Temperature Affects the Solubility of Gases
American Chemical SocietyAdd to list DetailsIn this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water. Learners design their own procedure,...
Dissolving a Substance in Different Liquids
American Chemical SocietyAdd to list DetailsIn this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving. The sugar will dissolve to a different extent in each...
Comparing the Amount of Acid in Different Solutions
American Chemical SocietyAdd to list DetailsIn this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar. By comparing the number of drops used to return each solution back to its blue...
Dissolving Different Liquids in Water

Color Changes with Acids and Bases
American Chemical SocietyAdd to list DetailsLearners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base. Learners can follow up their study of acids and bases...
Neutralizing Acids and Bases
American Chemical SocietyAdd to list DetailsLearners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid. Use this as a follow-up...
Mysterious M&M's
American Chemical SocietyAdd to list DetailsLearners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M. This introductory activity...
Colors Collide or Combine
American Chemical SocietyAdd to list DetailsLearners place multiple M&M's in a plate of water to watch what happens as the candies dissolve. Often learners expect the colors from each M&M to blend when they come together, but...
