Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

Owl Pellets
Source Institutions
In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

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.

What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

Tobacco Mosaic Virus
Source Institutions
In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

Antigen-Antibody Testing: A Visual Simulation or Virtual Reality
Source Institutions
In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.

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.

DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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.

Altered Reality
Source Institutions
In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

Mapping Sea Level Rise
Source Institutions
In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

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.

Amphibian Skin
Source Institutions
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

Air-filled (Pneumatic) Bone Experiments
Source Institutions
Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.
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.

Dirt Life
Source Institutions
After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).
Are you a Supertaster?
Source Institutions
In this activity, learners examine their tongue and taste buds.
