American Chemical SocietyAdd to list DetailsIn this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases. Learners create colorful rainbow trout artwork using universal...
Hot and Cold
SciencenterAdd to list DetailsIn this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain. With this understanding, they try to find a combination of chemicals that could be used to...
Ants
Lawrence Hall of ScienceAdd to list DetailsIn this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food. Learners attempt to discover an ant "superfood" and use that food...
Fruit Juice Mystery
SciencenterAdd to list DetailsIn this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar. Learners add vinegar (an acid) and washing soda solution (a base)...
Disappearing Colors
SciencenterAdd to list DetailsIn this challenge, learners figure out how to make a juice stain disappear. (Younger learners will definitely need assistance, and safety instructions are included in the PDF.) First they...
Illuminations on Rates of Reactions
The ExploratoriumAdd to list DetailsIn this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
Plant Power
SciencenterAdd to list DetailsIn this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen. Multiple fruits and vegetables, both raw and...
