Energy Choices Board Game
Source Institutions
This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.
Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

Star Power
Source Institutions
In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

Resonant Rings
Source Institutions
Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

Postcards from Space
Source Institutions
Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.
Shrinkers
Source Institutions
Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
Concentrate: Concentrations and Reaction Rates
Source Institutions
Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

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

Find the Best Way to Clean Oil off Bird Feathers
Source Institutions
