Human Traits
Source Institutions
In this activity, learners investigate variations in human traits. This allows learners' natural curiosity about their identity to draw them into the study of heredity.

Seeing the World Through a Different Lens
Source Institutions
Learners participate in a variety of activities modeling different disabilities.

A Closer Look at Crystals
Source Institutions
In this activity, learners compare different types of salt crystals under a magnifying glass.

Rubber Band newton Scale
Source Institutions
In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

Thar She Glows!
Source Institutions
Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.

Swirling Milk
Source Institutions
In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

Everyday Poisons
Source Institutions
This reading and writing activity (on pages 2-9) teaches what plant parts should be avoided, how a person can get rid of toxins, symptoms of plant poisoning, and how plants create poisons to repel pre

Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

Two-String Yo-Yo
Source Institutions
Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

Unlocking the Secret in Product Codes
Source Institutions
In this activity, learners will explore how product barcodes are scanned accurately and be able to "guess" the last number in a 13 digit barcode correctly every time.

Frog Olympics
Source Institutions
Did you know that a bullfrog can jump a distance of 10 times its body length? Learn more about nature's most acrobatic amphibian, the frog, through this set of short, hands-on activities.

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

Seed Adaptations
Source Institutions
By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

Benham’s Disk
Source Institutions
In this activity (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.

Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Probability: Rock Around The Clock
Source Institutions
In this math lesson, learners apply the Monte Carlo method of simulation to determine a reasonable estimate.

Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

Stained Glass Glue
Source Institutions
In this activity on page 6 of the PDF, learners use glue instead of glass to create artwork that can be hung in a window.

Marble Challenge
Source Institutions
In this physics activity (page 6 of the PDF), learners will try to keep a marble in a bottomless cup without touching the marble inside.
