Maths for AS Chemistry
No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

If Hot Air Rises, Why Is it Cold in the Mountains?
Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

Hydrocarbons and Fractionation
For this compounds worksheet, students identify molecules as compounds and provide a reason why they believe it is or is not a compound. Students write out chemical formulas. This worksheet has three problems to solve.

The Energy of Evaporation
Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...
Museum of Science
The Atom's Family: Mighty Molecules
In this activity, students construct models of molecules using marshmallows and gum drops.
Other
The Science House: Floating Candles
In this experiment students observe a combustion reaction and deduce the components necessary for the reaction to occur. They also see the relationship between pressure, volume, and number of molecules for gases.
Exploratorium
Exploratorium: Science Snacks: Conversation Piece
Did you know a balloon filled with carbon dioxide can act as an amplifier? In this activity test how sound travels through carbon dioxide molecules.
American Geosciences Institute
American Geosciences Institute: Earth Science Week: Chemistry of Burning
In this activity, students use pipe cleaners and foam balls to build a model of a hydrocarbon molecule. They then modify it to demonstrate the chemical reaction that happens when the hydrocarbon is burned.
Bill Nye
Bill Nye: Sock It to Me
This tutorial by Bill Nye explains how evaporating water (or sweat!) can cool you down.
PBS
Pbs Teachers: Bottle Fountain Experiment
Demonstrate how heating expands air molecules by constructing a bottle fountain powered by air pressure.
PBS
Pbs Teachers: Hot Air Balloon Experiment
Explore how heat affects the density of air by building and flying a hot air balloon using large plastic bags and the hot air from an electric hairdryer.
