Individual Responses Can Be Different

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

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...

Provide high schoolers with their own indoor gardens! Emerging scientists discuss the process of photosynthesis and germinate seeds before growing plants in multiple lighting conditions. The hands-on application allows pupils to see...

Students understand how they can incorporate dietary guidelines in their daily life.  In this investigative lesson students set dietary goals and incorporate an activity to learn how to create a new seed variety while studying dispersal...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Students measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

In a 15-minute lecture, a neurobiologist expounds upon the function of the human brain. So many of the pharmaceuticals prescribed for psychiatric disorders have unacceptable side effects. He shares current research that holds hope for...

Students examine how all levels of government react to chemical emergencies. They identify activities which could lead to an emergency. They discuss how they respond to contaminants released into the air.

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...

Students study plants and what they need to thrive and survive. They make plant extracts from chosen wetland plants and test their allelopathic effects on the germination rate, radicle growth, and hypocotyl growth of test seeds of other...
