Decomposition vs. Synthesis Reaction

More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

What is a chemical reaction? Learn about chemical equations, the four types of chemical reactions, and other fun facts.

Explore the chemistry behind the airbags that keep you safe in a collision. Using a simulation, your classes find the best gas to use to inflate an airbag. The simulation shows the time it takes to inflate to a maximum volume....
