Enzyme Action
Source Institutions
In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

Multi-Variable Relations: Stressed to the Breaking Point
Source Institutions
In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.
Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

Smell the Difference
Source Institutions
In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

Frijolitos
Source Institutions
Esta actividad enseña la proporción y razón por hacer que los aprendices hagan "ensaladas" que combinan tres tipos de frijoles en tres combinaciones diferentes.

Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

Invisible Ink
Source Institutions
In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

Make a Salt Volcano (Lava Lite)
Source Institutions
This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

Molecular Menagerie
Source Institutions
In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Testing Vitamin C: Chemistry's Clear Solution
Source Institutions
In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

Bubble Bomb
Source Institutions
Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

Computation and Estimation: Alphabits
Source Institutions
In this math lesson, learners apply the concepts of ratios and percentages to the distribution of letters contained in a box of Alphabits® cereal.

Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
