Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...
Lesson Planet: Curated OER
Energy Foundations
Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and readings. Scholars...
Lesson Planet: Curated OER
The Rate of a Chemical Reaction
If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...
Lesson Planet: Curated OER
Endothermic and Exothermic Reactions
Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical composition...
Lesson Planet: Curated OER
Change in Temperature - Endothermic Reaction
Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...
Lesson Planet: Curated OER
How to Blow Up a Balloon With Baking Soda & Vinegar
A simple combination of baking soda and vinegar creates enough carbon dioxide to blow up a balloon! It's an awesome illustration of chemical reactions for upper elementary learners, or use it with slightly older scientists to introduce...
Lesson Planet: Curated OER
Exothermic and Endothermic Reactions
How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...
Lesson Planet: Curated OER
Can You Design a Hot or Cold Pack?
You're getting warmer. Groups conduct an experiment to determine which of four chemicals are in hot/cold packs. They learn about exothermic and endothermic reactions and use this knowledge to design a hot/cold pack that is small enough...
Lesson Planet: Curated OER
How Much Heat Can a Phase Change Produce?
Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.
Lesson Planet: Curated OER
How Much Energy Is That Anyway?
The fifth lesson in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.
