Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.
Join the Dinosaur Age
Source Institutions
In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.
Workin' It Out
Source Institutions
In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Exploring Shadows
Source Institutions
This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan
Exploring Structures
Source Institutions
This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different
What Trickles Down?
Source Institutions
Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.
Serving Sizes
Source Institutions
In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels
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.
Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.
Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin
Air, It's Really There
Source Institutions
This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.
Dinosaur Interaction
Source Institutions
In this activity, learners explore why animals, specifically dinosaurs, live in families.
Neural Network Signals
Source Institutions
In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
Weighty Questions
Source Institutions
In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.
Making Regolith
Source Institutions
This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?
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
What's in the Water?: Biotic and Abiotic Elements in Aquatic Ecosystems
Source Institutions
In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.
Muscle Fibers
Source Institutions
In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.
Don't Stop for Hitchhikers
Source Institutions
In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.
