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.

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.

The Snack Shop
Source Institutions
In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.

This Bitter Be Good
Source Institutions
In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

¡Helados!
Source Institutions
En esta tira cómica, Mateo y Cientina emplean su conocimiento de la química y las medidas para esta actividad deliciosa - ¡hacer helado!

Sweetly Balanced Equations
Source Institutions
In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

Three Bean Salads
Source Institutions
This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

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.

Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

Joe's Place
Source Institutions
In this math activity (Page 8 of the Dining Out! PDF), younger learners select items from a menu and count out the total amount needed using the fewest bills and coins possible.

Jiggly Jupiter
Source Institutions
In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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.

Ziptop Bag Chemistry
Source Institutions
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.

Potato Power
Source Institutions
Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

How Boulders Are Born
Source Institutions
In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

Number of Mentos vs. Height: Soda Geyser Series #5
Source Institutions
In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

Dye Like A Natural
Source Institutions
In this activity, learners stain fabrics--on purpose!
