Make Your Own Slushies
In this activity, learners will make their own slushies and learn some of the science behind how the process works.
LEGO® Chemical Reactions
This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).
Change in Temperature: Endothermic Reaction
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Hot and ColdAdd to list Details
In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.
Ziptop Bag Chemistry
In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.
Matter of DegreeAdd to list Details
In two separate bags, learners mix water with Epsom salts and detergent.
Hot and Cold: Endothermic and Exothermic ReactionsAdd to list Details
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
Hot & Cold
In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.
