Temperature Changes Everything

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...

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...

Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...

Pupils compare the temperature change in a closed and open box as a demonstration of the greenhouse effect. 

Ready for a lesson on the wonders of cooking? Young scientists view the short video segment and explore the science of temperature changes on physical and chemical properties in food as the cooking process transforms raw ingredients into...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of...

Students determine the effect of temperature on the motion of particles. They study the difference between particles in a gas, liquid, and a solid and see how the characteristics of solids, liquids, and gases can be explained by particle...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

Get your class thinking about climate change as a scientific theory. Guided by a handout, emerging earth scientists read articles and take notes about glaciers and sea ice. To conclude, they write an evaluation of the evidence for...
