Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

LEGO Robots
Source Institutions
This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

Average Names
Source Institutions
In this activity, learners compare the number of letters in the names of the people in their families or group of friends.

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

Making Mosaics
Source Institutions
In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

Games of Chance and Brains
Source Institutions
In this activity, learners build and play three math games. In the first game, called "Switcheroo," learners place marbles in holes 1 through 4 and 7 through 10.

Enciérrelo
Source Institutions
Jugando a este juego de estrategia, los chicos desarrollan su entendimiento de área y perímetro. En su turno, cada jugador hace una línea entre dos punto contiguos en la cuadrícula.

Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

Fingerprint Identification
Source Institutions
In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Food Grab
Source Institutions
In this outdoor activity, learners design devices that will catch prey or gather plants.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

The Muddy City: Minimal Spanning Trees
Source Institutions
In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

Tracking Otters
Source Institutions
This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.
It's A Gas!
Source Institutions
Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
All Mixed Up!: Separating Mixtures
Source Institutions
Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

Tug-of-War
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.
