Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Here is a straightforward practice test for first year chemistry learners. Responders balance equations, identify types of reactions, represent electron configurations, and solve stoichiometry problems. Keep this handy to use as...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...

In preparation for an introduction to chemistry exam, play Chemistry Jeopardy with your class. The categories include molar relationships, phases of matter, atomic structure, chemical nomenclature, and scientific investigation. If the...

Learners explain the laws of volume and pressure, identify what a limiting reagent is and why it is important in a chemical reaction, and distinguish between fossil fuels and renewable energy sources.

In this chemistry overview worksheet, students review stoichiometry, states of matter, thermochemistry, gas laws, chemical bonding, molarity, chemical equilibria, and kinetics. This worksheet has 41 problems to solve.
