Racing M&M Colors
Source Institutions
Learners design their own experiment to determine which M&M color dissolves the fastest in water.

Another Bright Idea!
Source Institutions
In this activity on page 5 of the PDF, learners use their knowledge of energy and batteries to create homemade flashlights.
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.

Urine the Know
Source Institutions
In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

Shapes and Colors and Textures, Oh My!
Source Institutions
This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

Why do Raindrops Sometimes Land Gently and Sometimes Land with a Splat?
Source Institutions
In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Burn a Peanut
Source Institutions
In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

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.

Exploring Moisture on the Outside of a Cold Cup
Source Institutions
In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

Beach Finds Curiosity Cart
Source Institutions
In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

The Primary Colors of Light
Source Institutions
In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

Wheat Germ DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

Yogurt Cup Speakers
Source Institutions
Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Estuaries
Source Institutions
An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

Secret Goldenrod Messages
Source Institutions
In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.
