Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

Stiff Bones, Bendy Bones
Source Institutions
Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

Exploring Materials: Hydrogel
Source Institutions
In this activity, learners discover how a super-absorbing material can be used to move a straw.

Water Striders
Source Institutions
In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

Make a Balloon-powered Nanorover
Source Institutions
In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

Jar Races
Source Institutions
In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

Weather Stations: Temperature and Pressure
Source Institutions
In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

Exploring How Robots Move
Source Institutions
In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

Spectroscope
Source Institutions
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

Stop the Stretching
Source Institutions
Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

Homemade Bath Fizzies
Source Institutions
In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

Jiggly Jupiter
Source Institutions
In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

Salty Pits
Source Institutions
In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

Dress Like a Frog
Source Institutions
In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

Carbon Dioxide Removal
Source Institutions
In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

Washing Air
Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

Colored Shadows Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.
