Seismic Slinky!
Source Institutions
Did you know that a Slinky makes a handy model of earthquake waves?
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Glue Stick Sunset
Source Institutions
In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.
The Game of Life: Stem Cell Edition
Source Institutions
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
Straws and Pins
Source Institutions
In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.
Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.
A Mole of Gas
Source Institutions
In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.
Macro-Microarray
Source Institutions
In this activity, learners explore the "nuts and bolts" of gene chips.
Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.
To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).
Cylinders and Scale
Source Institutions
In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.
Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
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.
Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
Carbon Configurations
Source Institutions
In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
M&M® Model of the Atom: Edible Subatomic Particles
Source Institutions
In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).
Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
Geodesic Gumdrops: Candy and Toothpick Architecture
Source Institutions
This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.
