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.
Film Canister Farming
Source Institutions
In this hands-on botany activity, learners sprout vegetables in film canisters.
Growing Plants: Track Their Growth
Source Institutions
In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.
Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.
If You Lived in a Forest
Source Institutions
This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.
Amphibian Skin
Source Institutions
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.
Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
Straws and Pins
Source Institutions
In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.
Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.
Balancing Act
Source Institutions
In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
COSI's Bubble Recipe
Source Institutions
Everybody loves bubbles, and this is the best bubble recipe ever!
Animal Guess Who
Source Institutions
In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.
Topographic Investigation: Map an Underwater Surface
Source Institutions
In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.
Roller Coasters
Source Institutions
In this activity learners will build roller coasters and test them using small balls or marbles.
Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.
Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.
Hungry as a Caterpillar
Source Institutions
In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.
Nature Journals
Source Institutions
In this activity, learners construct a home-made journal with simple, everyday materials.
