Ice Energy

Ready to take your chemistry class on its first big lab adventure? Dive in to differentiation between chemical and physical changes with a thoughtfully designed set of experiments! Partners conduct a series of reactions, describe their...

Before completing this worksheet, chemists are supposed read a portion of their textbook. Assign the chapter on bond energies, endothermic, and exothermic reactions. Then have your class answer the questions and fill in the data tables...

The amount of energy Americans use doubles every 20 years. The first lesson plan in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in...

If you have taught the first activity in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

What happens when chemical bonds break and form? Science scholars explore the movement of energy in a chemical system by watching a well-rounded video. The narrators illustrate exothermic and endothermic reactions in terms of temperature...

Mr. Mole and Mr. Matchmaker entertain and educate your chemists about how quickly or slowly reactants are used up in a chemical reaction. Thorough explanations of the influencing factors are offered, and demonstrations are done. After...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Learners study about electrochemistry by increasing their understanding of electron transfer and its role in chemical changes. They explain that energy appears in different forms. Heat energy is in the disorderly motion of molecules.
