Bbc: Gcse Bitesize: Heat Energy Changes in Chemical Reactions

Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Learn about how chemical reactions require energy to activate and how to draw energy diagrams for chemical reactions. After watching the video, learners discuss why mixing hydrogen and oxygen gas in a balloon won't result in water.

Teach the basics of writing chemical equations with a video introduction. The video lesson discusses the components of the chemical reaction and how chemical equations represent each. The discussion includes mention of catalysts and...

Students will conduct two chemical reactions: endothermic and exothermic. They will see an animation that shows that it takes energy to break bonds and that energy is released when new bonds are formed, and use that animation to explain...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Follow the energy conversion from potential to kinetic in this interactive activity that explores total energy in chemical reactions.

Use these demostration video clips to help understand the energy changes in some chemical reactions.

How are chemical reactions like dating? A collision must first occur! In this hilarious approach to speeding up chemical reactions, viewers find out that five changes can increase the rate of reaction: smaller space, increased number of...

In this chemistry practice test worksheet, students review their knowledge of energy changes in chemical reactions as they answer 17 multiple choice and short answer questions.
