Human Body Project Ideas
Rate of cognitive decline in different elevations.
Oxygen partial pressure decreases with altitude, challenging blood oxygenation which may affect brain function. If you’ve ever felt some altitude sickness, then this is exactly what’s happening. This is because the atmospheric pressure decreases at higher elevations, leading to a decrease in the partial pressures of the gasses in the air, including oxygen. And of course, oxygen is needed for us to function. What is the effect on brain health/ cognition in sudden increased elevation: say, climbing Mount Everest? Does chronic exposure to high elevations increase the likelihood of dementia? In this project, a meta-analysis of published works examining the effects of altitude on cognition would be conducted.

Building a Blood Vessel
Use online graphics to illustrate how a blood vessel forms. Blood vessels are structures that carry blood and are responsible for transporting nutrients and oxygen throughout the body. There are three main types of blood vessels: arteries, veins, and capillaries. For this project, complete a literature search to understand what is known about blood vessel growth. Then, utilize this information to generate a graphic with no words to demonstrate how the vasculature (network of blood vessels) forms. The goal of this project is to explain science without using text and therefore make it more available to a larger community.

Regulation of Circadian Clocks
Sleep is known to be governed by two distinct processes: a circadian clock that aligns sleep and wakefulness to the solar day and the sleep homeostat that encodes for sleep debt as a compensatory mechanism against sleep loss. You’ve most likely heard about circadian rhythm and our body’s internal clock, and circadian regulation of sleep is a fundamental process that allows animals to anticipate sleepiness or wakefulness consistently every day. These mechanisms can be regulated in multiple ways: at the gene, protein, gene, and clock neuronal level. In this project, we will focus on 1) how to efficiently digest primary and review articles to compile and condense information, 2) investigate how circadian clocks are regulated at these different genetic levels, and 3) try to effectively summarize the information we've gathered. We can present this information in a variety of ways, and what the final product looks like is up to you.

The Biology of Aging
Aging is the number one risk factor for a variety of diseases including cancer, neurodegenerative disease, and loss of hearing/sight. We are only now beginning to truly understand the process of aging and have even started to uncover ways that we could stop, or potentially reverse, the effects of aging. What are the hallmarks/signs of aging? How do researchers study 'aging'? How does human lifespan and aging compare to the rest of the animal kingdom? Is it possible to stop or reverse the effects of aging? What advancements are being made related to this? We could explore these questions or brainstorm others you might have about the biology of aging.

Animals, Plants, and Nature Project Ideas
How genetically engineered mosquitoes are reducing rates of vector-borne diseases such as zika.
Many countries are already releasing millions of genetically engineered mosquitoes into the wild every week. These mosquitoes have been modified to reduce their ability to transmit disease-causing pathogens like dengue fever, Zika, and malaria, and are sent into the wild to mate with disease-carrying mosquitoes. However, this is still controversial as some people are concerned about the unintended consequences on the environment. What could be the potential pros and cons for this? The project will mainly focus on doing meta analysis of articles and watching informative videos to understand how/why genetically engineered mosquitoes can be used to reduce rates of different diseases. Students will have the chance to use critical thinking and do in-depth research on genetic engineering techniques, how scientists determine breeding rates and number of insects released, and epidemiology of different bloodborne diseases.
Idea by mentor Vanessa
Efficacy of Marine Protected Areas
Marine protected areas (MPAs) are areas of ocean or coastal waters that are set aside for the conservation and sustainable use of marine resources. These areas are established by governments, NGOs, or other organizations, and they can take different forms, from fully protected "no-take" zones to areas with regulated fishing or other activities. Marine protected areas have the potential to guide sustainable resource management and protect biodiversity, but have a host of reasons for why they are not currently effective. Explore reasons for why MPAs may not be effective. Then develop a framework for mapping, modeling, and implementing an effective Marine Protected Area.
Bioinspiration: Do animals hold the answers?
Can the toxins produced by frogs help us fight antibiotic resistant bacteria strains? How can understanding how lizards and newts regrow their limbs help us improve wound treatment? Why do tilapia skins help with burns? Discover the role of animals in the development of modern medicine as well as its potential. Are there any ethical concerns with these developments and findings? If so, what are they and do they matter? Share your findings in a research proposal, article, or presentation.

How Climate Change Can Affect Future Distributions of Rare Species
Climate change, such as global warming and longer drought, can threaten the existence of some of the rarest plants on earth. It is important to understand how future suitable habitats will change for these rare species so that we can target our conservation efforts in specific areas. In this project, you will identify a rare species that you like (it can be animals, plants, or fungi!), and gather the data online on its current occurrences. Then you will learn how to perform species distribution modeling to map its current and future suitable habitat areas. To get you started on learning species distribution modeling, check out this Youtube resource here. The changes in the amount or location of future suitable habitats can significantly affect the destiny of a rare species. By doing this project, you will not only learn skills in data analyses but also become the best ambassador for this rare species that you love.

A Reef’s Best Frenemies
Coral reefs are in global decline. A primary cause of this is "coral bleaching" which results in the white reefs we often see in the news. Coral bleaching is actually the breakdown in the partnership between the coral animal and tiny, symbiotic algae that live within its cells. Corals and algae have a variety of thermal tolerances which are likely decided by genetic and environmental factors. However, despite how important this relationship is, it's currently very poorly understood. This project would review existing literature on the symbiotic partnernship and try to identify factors that predict bleaching and thermal resilience.

The Amyloid Hypothesis: Sifting through the controversy
For many years, scientists have thought that amyloid beta was the protein responsible for a patient developing Alzheimer's Disease symptoms. This "Amyloid Hypothesis" is now being questioned in light of current clinical data. Recently, drugs have been developed that reduce amyloid beta in patients. Surprisingly, the drugs worked in reducing amyloid beta, but it did not result in the slowing of disease pathology. Does this mean that the amyloid hypothesis is incorrect? Is amyloid beta less important in the progression of disease then what we once thought? This research project aims to explore the issues with the amyloid hypothesis and to assess where we stand in our understanding of amyloid beta's contribution to Alzheimer’s.

Idea by mentor Helen
Sleep Disruption Profiles in Various Mouse Models of Alzheimer’s
Alzheimer's disease (AD) has been studied for decades but we are no closer to understanding the mechanisms of the disease. Because of the vast number of researchers studying AD, there are numerous models used to study the disease. All these models have different sleep profiles, phenotypes, disease onsets, sex differences etc. Therefore, in this project we will compile a document based on extensive literature review about the various models there are. We will focus on sleep profiles in these animals with an emphasis on male and female differences. This information is valuable because it is important to know which model is best to use to answer your scientific questions and there is a lot of criticism (by other scientists) that can be brought on by the model chosen so you need to be able to justify your choice. This project will also introduce you to the world of AD research and some of the gaps in knowledge in the field.

Rethinking The Treatment Of Neurodegenerative Diseases
Neurodegenerative diseases affect millions of people worldwide. They are conditions that affect the nervous system, particularly the brain and spinal cord, and examples include Alzheimer’s and Parkinson’s. While billions of dollars have been spent trying to find treatments for the disease, very few drugs and therapies have had a meaningful impact on slowing down disease progression. This is often because by the time someone is diagnosed with a disease, it has progressed too far for a treatment to have a substantial effect. Some recent approaches to treatment have turned to looking for early indications of the disease (termed "biomarkers") that can occur before the onset of symptoms. By diagnosing disease and beginning treatment before symptoms arise, these treatments could have a more profound effect in slowing down the progression of disease. Students could review the recent progress being made on identifying biomarkers for neurodegenerative diseases, and either write a paper or even record a podcast on their findings!
Idea by mentor David
Genetics Project Ideas
Height and genetics: nature or nurture.
How much do your genes determine your height? How much do nutrition and environmental factors play a role? What gene variants are implicated in height differences and what is the role of epigenetics? Epigenetics is the study of heritable changes in gene expression or cellular phenotype that occur without changes to the underlying DNA sequence. These changes can be influenced by diet and lifestyle. We will access and analyze an open dataset on twins to estimate the correlation between monozygotic twins (who have the exact same DNA) and height. You will learn to use R to open a dataset, analyze data with statistical methods such the student’s t-test, and display your data as graphs and charts. Finally, you will learn how to make a research presentation on height and genetics, describe the research methods, and present the data in a compelling and thorough way.
Idea by mentor Adeoluwa
The World of Personalized Medicine
Similar to our fingerprints, our genetic code is also unique to each individual person. Our genetic code is what determines our hair color, height, eye color, skin tone...just about everything! For those that develop diseases such as cancer, their genetic code found inside the malignant cells that comprise a tumor may also be unique to them or to certain groups of people with similar mutations (the drivers of disease). So why is it that we treat each person the same way even though the genetic drivers of that disease may be disparate? The world of Personalized Medicine is new and exciting and looks to circumvent this problem. Personalized Medicine (also known as precision medicine) uses the genetic code of a patients disease to guide treatment options that prove to be highly efficacious. Together, lets write a review on a disease of your choice that could benefit from Personalized Medicine based on current literature and research.

General Biology Project Ideas
Teach a biology concept two ways: to your fellow students and to the general public.
One of the best ways to learn is to teach. Choose a biological concept that interests you and prepare a lesson and or demo on it. The format should be a video recording of yourself teaching (a la Khan Academy or a Zoom class), but the other details are up to you. Consider incorporating a demonstration (e.g. how can you use items from your kitchen to illustrate properties of mixtures?) or animation (e.g. to illustrate molecular motion). Also consider how you will check that your students understand the concept(s) and/or skill(s) you have taught them. Prepare and record two versions of your lesson: one intended for your peers and one for the general public. How will the versions differ to reflect these different audiences? You will learn what it's like to teach, gain a much greater understanding of your chosen concept(s)/skill(s), and learn how to communicate science to different audiences.

What is Biology
Simply said, biology is the study of life.
Biologists now agree that life is a product of a certain set of processes that arise from the arrangement of matter.
Biologists have compiled a list of features that define the “set of life processes” shared by all organisms as living: The living:
- Use up stuff and power.
- To have offspring; to perpetuate one’s genes.
- Evolve and expand.
- Demonstrate inherited differences or variants.
- Are well-suited to their natural habitat.
- React to external influences.
The scientific nature of biology has led to the categorization of life’s defining features into the following categories:
- Harmony and Variety
- Constancy in Genealogy
- Characteristics of Human Nature
- Harmony between Form and Operation
- Organism-Environment Interactions
All of the Life Science classes have a common thread of these key ideas.

Biology Projects are great teaching tools educators can use to boost student interest in the subject and spark classroom participation.
Testing plants and gravity
Testing root growth in relationship to gravity is a fun and simple idea. To do this, students need to cut a strip of paper towel approximately one inch wide. Then, they lay pinto beans on the strip and roll it up. Next, moisten the strip and tape it to a square of cardboard, placing the entire thing in a zip top bag. Finally, place it in a warm window and observe over time and look for roots and stems to sprout.
Once the roots and stems sprout, students will notice that the sprouts point up and the roots point down. After making this observation, students should turn the bag so the plant is growing sideways, then upside down, continuing to observe root growth with these changes
Fruit flies and tea
Tea is often offered as a healthful drink, but which tea is the most healthful? This project tries to answer that. To set up the fruit fly and tea experiment, students must create a mixture of tea and fruit fly food. This works best when students choose four different teas to test four different groups of flies. A fifth group — the control group — will receive fruit fly food with plain water. The tea should be brewed by seeping a tea bag in three tablespoons of boiling water for a set period of time. Then, it should be mixed with fruit fly food.
Once the food is prepared, it should be added to five separate vials. Then, each vial receives 10 adult fruit flies. Every day, the fruit flies that remain alive should be removed and transferred to a new vial that contains the same tea and food mixture. This should be repeated until all fruit flies have died. The student can then determine which food/tea mixture provided the greatest longevity to the flies.
Cleaning oil off birds
When birds are coated with oil after an oil spill, their life is at risk. This project will test a variety of solvents to determine which is the best to use in this situation. It uses feathers, not live birds, to make this determination.
The experiment begins with weighing several sets of feathers, then dipping bird feathers in oil. After the feathers are dipped, they are weighed again. This shows the weight of the oil on the feathers and serves as the means of measuring the effectiveness of the solvents.
Once they are all dipped and weighed, the feathers are washed in a range of cleaners, with one group remaining unwashed to serve as a control. After washing, the feathers are weighed yet again. This should indicate which solvent is the most effective, as the feathers washed in it will show the most oil weight loss.
Vitamin C and colds
Vitamin C is often offered as a solution to help prevent the common cold. This simple experiment helps determine if there is much fact to this common bit of advice. The student selects two groups of willing participants, preferably people who do not live in the same house. One group will agree to take a vitamin C tablet daily for a month, while the second will agree not to. All will record any cold symptoms they experience during that month.
At the end of the month, the groups will switch. After a second month, the data can be collected and analyzed to determine if taking vitamin C made a difference in cold symptoms.
Each of these biology project ideas tackles a different aspect of the subject, including botany, environmental science, human biology and zoology. They all provide an interesting way to present important biology ideas to students in a way that encourages inquiry.

Dissecting a frog is a quintessential part of high school biology. If possible, try to get both female and male specimens for your class so students can see the eggs and compare the insides to the male frog.
High schoolers can get a bit squirmy about frog dissection. Have a flower dissection instead. The teens can find and label the female and male parts of the flower. It can be fun for high schoolers to check out flower intricacies under a microscope.
Diversity Among Plant Samples
Another simple biology experiment involves going into your natural environment, such as a local park, to observe diversity among plant samples. To make the experiment more detailed, students can rub collected samples on filter paper to observe which plants present which colors . Teens can work to find out why certain plants present certain colors.
It can be enlightening to show kids how phototropism affects plants. They can set up an experiment by using different materials to affect light. They can see how affecting the light affects the growth of the plant.
Water From Common Sources
Water is everywhere. Unfortunately, water contains numerous elements too. A great experiment is collecting water samples from various sources and viewing them under a microscope. Students can then compare their results and attempt to postulate why a given water source would present more organisms than another would.
Another experiment involves taking a piece of bread to monitor the molds that grow over a period of two weeks.
Everyone has their own taste. Literally! Some people like sour things while others like sweet. Find out if everyone perceives taste the same way and has the same threshold for taste by doing an in-class experiment.
Ever wonder how effective hand sanitizer is at killing bacteria? Test it! Grow bacteria in a Petri dish along with paper soaked in peroxide, white vinegar, rubbing alcohol, etc. Find out how each one of them works to inhibit bacteria growth.
Pea Plant Genetics
Students can recreate Mendel's genetic pea plant experiments . By growing pea plants and comparing their phenotypes, students can determine each parent plant's genotype.
Fingerprints are pretty amazing features on the human body. Not only can you use them to open your phone, but each one is unique . Put your fingerprint on paper and examine the different aspects of the lines and arches on your fingers. Compare fingerprints among everyone in class.
Comparing Animal and Plant Cells
To better understand animal and plant cells, students can compare cells from their cheeks to cells from an onion. Just stain the cells with iodine or another dye to better see the cell structures under a microscope.
Creating a DNA model is a great way to help students understand the structure and function of DNA in genetics. Students can use candy, string, and toothpicks to develop a fairly realistic model of the double helix structure.
Water Bottle Germs
Many people refill their water bottles in high school. But do they add germs or bacteria to the bottle? Is refilling a disposable water bottle safe? Have students take swabs of the water bottles they use and look for bacteria around the lid or on the bottle.
Teens use a lot of hair products. But do they truly work? Have teens in your class take a few samples of their hair. See what happens to the hair when common hair products are added.
Understanding the water cycle isn't hard. But teens can look at it firsthand by creating a water cycle experiment. Just have them fill a baggie with water and tape it to a window. They will watch evaporation, condensation, and precipitation in action.
Closed Ecosystem Bottle
It can be hard for students to imagine something having its own ecosystem. However, you can use a plastic bottle to create a closed ecosystem.
Field Survey Biology Experiment
This experiment is great because it is cheap, easy, and you can do it in a variety of areas around your school or send students home with it. The goal is to observe the surrounding area over time and monitor the samples that you collect.
Materials You'll Need
For this experiment, you need to grab:
- Jar or baggies to collect samples
- Stakes and string or cones help mark an area
- Paper or journals for taking notes
- Slides, slide covers, and a microscope
Take note that you will observe your area for several months, so choose an area that is easy to re-mark or where you can leave the markings up, so you return to the same designated area each time.
- Have students choose one spot to observe. The spot should be no more than two to three feet square.
- Do you see evidence of animals? (Look for prints, scat or guano, fur, owl pellets, etc.)
- What plant life do you see? (Look for moss, lichen, weeds, and other plants).
- What fungus do you see? (Look for mushrooms and other fungal growth).
- What insects do you see? (Encourage students to look specifically for relationships here - such as connecting mosquitos with water or bees with flowers or a hive).
Sampling and Classroom Instructions
Bring the research back into the classroom by following these instructions.
- Guide students to make connections and note relationships in their marked area. Have them inventory the area and draw a crude map of where everything is.
- If possible, have students use tweezers and gently take samples of soil, fungus, moss, plant life, insects, etc.
- pH value of soil or water
- Microorganisms in water
- Plant cells under a microscope
- Comparative structure of flowers you find
- Require students to record everything in their own journal or interactive notebook.
Teacher tip: Set up stations in the classroom for viewing, dissecting, drawing, testing pH, etc. This will allow students some choice in how they proceed with examining their specimens.
Testing for Bacteria
Have students see where the most bacteria are lurking. This experiment is great if you want a lab that has guaranteed results. There is always some kind of bacteria lurking somewhere, just waiting to grow in a student's Petri dish.
These are the materials you are going to need to have on hand.
- Prepared Petri dishes, three per student
- Sterile swabs
- Painter's tape
- Scotch tape
- Permanent Marker
- Graph paper
Material notes : You can also purchase sterile Petri dishes and agar separately; however, it is much more likely students will contaminate the plate before they swab.
Preparing Your Petri Dishes
Prepping your Petri dishes is an essential part of the experiment.
- Before opening any materials, have students identify three places (but in one physical location such as at home or at school) that they are going to swab for bacteria. Encourage them to hypothesize about which place they think will grow the most bacteria.
- Using the Petri dish, trace three circles on the graph paper and cut it out.
- In pencil, draw a line to denote the 'top' of the circle. It doesn't matter where you draw the line, but you will need something to show you how your Petri dish is oriented so you can be sure you're tracking the same colony each time you observe.
- On the back of the graph paper circle, note the location where you will take the swab, as well as the date you are taking the swabs. Do this for all three Petri dishes you have.
Have students bring their unopened sterile swabs and closed Petri dishes to the site. Carefully, they should:
- Set the Petri dish down on a flat surface.
- Unwrap the swab.
- Swipe the swab across the area they suspect has bacteria.
- Lift the lid, gently wipe the used swab across the agar, and close the lid, carefully but quickly.
Hint: Sometimes, it's helpful to tape the Petri dish shut so that the Petri dish doesn't accidentally lose its lid.
Now that you've swabbed the areas, it's all about the results.
- Have students draw Petri-dish-sized circles in their lab books or on separate graph paper. Draw one week's worth of Petri dishes for each dish the student has.
- As the colonies start to grow, have students draw the size in their notebooks, making daily observations. If they cannot observe daily, have them observe on the same day(s) over a month.
- They should also be recording the color and other notable features of their bacteria colonies in their lab books.
- At the end, the students should write a conclusion of their study.
The Effect of Light on Growth
In this lab, students investigate how light affects plant growth. Students may use any plants, but cress will grow more quickly, so your students can get results faster.
Gather up your materials.
- Styrofoam cup or bowl
- Potting soil
With your materials at the ready, it's time to start your experiment.
- On Day 1 - plant seeds in the soil in the cups.
- Label the cups according to the light you're going to use. You can compare sunlight vs. complete darkness, or you can compare several types of light.
- On each day after the initial day, take a picture of each cup and try to measure the growth, if any.
- For your lab entries, measure the sprouts, and note color and shape characteristics.
In this lab, students watch the rate at which planaria regenerates and test whether how you cut the planaria makes a difference as to how they grow back.
To conduct this experiment, you want to grab.
- 9 planarias
- 3 small plastic Petri dishes
- 1 large plastic Petri dish
- 1 plastic pipet
- 1 magnifying glass
- 1 plastic coverslip
- Spring water
- Paper towels
- Ice pack(optional)
Getting the setup right is half the battle when it comes to creating fun and interesting biology experiments for high schoolers.
- Start by numbering the three small Petri dishes to ensure nothing gets confused later.
- Using the pipet, move a planarian into the large Petri dish.
- At this point, you may want to try to set the Petri dish on an ice pack for a few minutes. This isn't totally necessary, but it will slow the planarian down to make it easier to cut.
- Right behind the head
- Right in the middle
- Right towards the tail
- Use the pipet to gently transfer each segment to a new Petri dish (with spring water).
- Repeat the steps with all remaining worm segments.
- Every day, observe the planaria. Regeneration will be considered 'complete' when the photoreceptors (the black dots that look like eyes on the planarian's head) appear.
Scientific Method and High School Biology Experiments
Much of high school biology is focused on instilling the elements of science in students. The scientific method is one of these main focuses. The method prompts participants in science to be investigators and to come up with a guess about what will happen in a given experiment, called a hypothesis. The point of the experiment is then to either prove the hypothesis correct through the experiment or prove it incorrect. This prompts teens to get involved in the scientific method while teaching other scientific skills, such as:
- The ability to make a rational estimate based on present factors and knowledge
- Close detail and monitoring skills
- The possibility of being wrong and how to move past that if it turns out to be the case
- Quick thinking skills
As much fun as biology experiments can be, there is an educational component spearheading the experiment.
Fun and Interesting High School Biology Experiments
For teens, high school biology can be fun. Finding the right experiment can help biology pop off the page and become more than just another required course of study. Who knows? Perhaps your student will even be prompted to enter a science fair or a career rooted in science?
