Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.

Harvesting Chemicals from a Battery
Source Institutions
In this activity, learners take apart a used zinc-carbon dry cell battery.

Getting Your Bearings
Source Institutions
In this activity, learners explore the concept of friction and how ball bearings reduce friction.

Macro-Microarray
Source Institutions
In this activity, learners explore the "nuts and bolts" of gene chips.

How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.

Instant Ice Cream with a Dry Ice Bath
Source Institutions
In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

Coral Snapshots: Biodiversity in Marine Protected Areas
Source Institutions
In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

Eyepatch Challenge
Source Institutions
In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

Wind Turbine
Source Institutions
Learners build a wind turbine and test it to see how much energy is created.

On Target
Source Institutions
In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

Mapping a Study Site
Source Institutions
In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

Flashy Fish
Source Institutions
Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.
Coastal Erosion: Where's the Beach?
Source Institutions
Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

Measuring Biodiversity
Source Institutions
Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

Isolation of DNA from Onion
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

Effect of Environment on Plant Growth
Source Institutions
The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
