Window Under Water
Source Institutions
Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.
Seeing Is Believing
Source Institutions
This activity is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Learners look through two cups with small holes in them to simulate what it'
Mystery Shapes
Source Institutions
In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.
Artificial Intelligence: The Intelligent Piece of Paper
Source Institutions
This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ
Starch Breakdown
Source Institutions
Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.
Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Small Habitats
Source Institutions
In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).
Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
Logs to Soil
Source Institutions
In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.
Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Creating a Local Field Guide
Source Institutions
In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.
Soak It Up: Understanding Amphibian Permeability
Source Institutions
In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.
Exploring Size: StretchAbility
Source Institutions
In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.
Exploring Structures: DNA
Source Institutions
In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.
Clear Water, Murky Water
Source Institutions
How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
