Colors Collide or Combine
Source Institutions
Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.
M&M's in Different Temperatures
Source Institutions
Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.
Exploring Baking Powder
Source Institutions
In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
Mysterious M&M's
Source Institutions
Learners 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.
Color Changes with Acids and Bases
Source Institutions
Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.
Change in Temperature: Endothermic Reaction
Source Institutions
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.
Temperature Affects the Solubility of Gases
Source Institutions
In 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.
Neutralizing Acids and Bases
Source Institutions
Learners 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.
New Sense about Cents
Source Institutions
In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.
Racing M&M Colors
Source Institutions
Learners design their own experiment to determine which M&M color dissolves the fastest in water.
Using Chemical Change to Identify an Unknown
Source Institutions
In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Milli's Insulation Investigation
Source Institutions
In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.
Dissolving a Substance in Different Liquids
Source Institutions
In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.
Iodine Investigators!
Source Institutions
In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.
Dissolving Different Liquids in Water
Source Institutions
In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.
Comparing the Amount of Acid in Different Solutions
Source Institutions
In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.
Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.
