chemistry variables worksheet

Variables in science teaching resources

Worksheets and ideas to get students thinking about control, dependent and independent variables in science (gcse and key stage 3).

Validity – the suitability of the investigative procedure to answer the question being asked, is all about controlling variables. For example, an investigation to find out if the rate of a chemical reaction depended upon the concentration of one of the reactants would not be a valid procedure if the temperature of the reactants was not controlled. 

Validity in science teaching

Making your results valid – controlling variables

Worksheet on control variables and the pollen count . Students read a passage about how pollen counts are carried out across the UK. They consider which variables must be kept the same i.e. controlled across the different sampling stations. Thanks to the University of Worcester ! ( PDF )

Worksheet on validity and writing a valid method . Students consider what the term ‘valid’ means. They plan an investigation to determine which fast-food restaurant has the saltiest chips. They must identify the dependent, independent and control variables when planning the experiment. Once they have completed the practical investigation, students use averages to display their data. ( PDF )

The independent variable

Changing only the independent variable . This short activity introduces the problems that arise when changing multiple variables at one time. A simple scenario involving a broken remote control helps students understand how changing more than one variable at a time makes it impossible to identify cause. Students work in pairs to discuss the problem and feedback ideas to the class. This would be a useful activity to do with students before introducing the concept of validity. ( PDF )

A simple context to plan an investigation to control variables

Once students have learnt about the need to control variables you could ask them to plan an investigation using the practical planner . A great context is curry! Ask students to plan an investigation into which drink relieves the burning sensation of curry the most: milk, coke, or water.  This context is familiar and so students can focus on variables as opposed to being distracted by the science. Variables to think about include – temperature of the curry and drinks, volumes, mass of curry eaten, chewing time and type of curry. Students will need to think about how to measure ‘hotness’ and relief. The science behind why milk works is here .

Lothar Meyer, upon hearing Avogadro’s hypothesis

It took chemists a long time to understand the nature of gases. Perhaps this was because of the ephemeral quality of gases or because experiments with gases required more sophisticated equipment that did experiments with solids or liquids. Nonetheless, once the Italian chemist Amedeo Avogadro (1776–1856) determined the true nature of gases, the mystery was solved and a more complete understanding of the atomic and molecular essence of matter was possible. This was Avogadro’s great contribution to chemistry, as Lothar Meyer so dramatically declared in the quote above. This unit explores the physical nature of gases, the laws governing the behavior of gases, and applications of gases from air bags to ozone depletion.

The Gas Laws and the Ideal Gas Equation

Because scientists like the Irish chemist Robert Boyle (1627–1691), the French chemist Jacques Charles (1746–1823), and Avogadro could easily observe the macroscopic gas properties of mass, pressure, volume, and temperature, they provided the data which eventually led scientists to understand what a gas must be like at the particulate level. These pioneers summarized their observations into a set of equations which are the foundation for the ideal gas equation. All of the other gas equations can be derived from the ideal gas equation, so it is important to understand it well. At low pressure (less than 1 atmosphere) and high temperature (greater than 0°C), most gases obey the ideal gas equation :

Each quantity in the equation is usually expressed in the following units:

  • P = pressure, measured in atmospheres
  • V = volume, measured in liters
  • n = amount of gas, measured in moles
  • T = absolute temperature, measured in kelvins
  • R = the ideal gas constant, which has a value of 0.0821 L atm/mol K

The ideal gas law was originally developed based on the experimentally observed properties of gases, although it can also be derived theoretically. It expresses the relationships among the pressure, volume, temperature, and amount of a gas. When Boyle and Charles studied the properties of gases in the seventeenth and eighteenth centuries, they studied the relationship between two of the variables, holding the others constant. Consequently, we have a set of simplified gas laws upon which the ideal gas law is based.

Boyle’s Law (1662)

At a given temperature and number of moles of gas, Boyle's Law states that the pressure and volume of a gas are inversely proportional. In the form of an equation,

PV = constant

Charles’ Law (1787)

At a given pressure and number of moles of gas, Charles' Law states that the volume and temperature of a gas are directly proportional. In the form of an equation,

VT = constant

Avogadro’s Law (1811)

At a given temperature and pressure, Avogadro's Law states that the volume and mass (number of moles, n) of a gas are directly proportional. In the form of an equation,

Vn = constant

Notice how the time line develops. The gas laws evolved over a period of nearly 150 years. During this time, scientists were struggling in an attempt to understand the particulate nature of matter, and it was Avogadro who finally made the breakthrough by recognizing the relationship between the macroscopic properties of gases and the particulate nature of matter. In order to standardize the literature about experiments with gases, scientists have adopted a convention whereby gas properties are often expressed at a set of conditions known as standard pressure and temperature (STP), defined as exactly 1 atmosphere and 273.15 K.

The Kinetic/Molecular Theory of Gases

Textbooks similarly state the details of the kinetic-molecular theory albeit somewhat differently. However, they usually summarize the same major points. Write a brief summary of the kinetic-molecular theory of gases , as presented in your textbook.

chemistry variables worksheet

this is great thank you

This is perfect, thank you

man is a legend

we still doin this 5 years later lmao

What's the answer for number 19? Thanks

No, in a non flexible container the volume cannot change to equalize internal and external press, so decreasing the external; pressure will not change the internal pressure

we still doing this a year later

we still doing this 3 month later
