Chemical Change
Source Institutions
In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

Ambiguous Cube
Source Institutions
In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

Handwashing Laboratory Activities: Bowl Technique
Source Institutions
In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

If Trash Could Talk
Source Institutions
Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

Pencil Balance
Source Institutions
In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

Ants
Source Institutions
In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

The Scoop on Scallops
Source Institutions
In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

Habitat Observations
Source Institutions
In this outdoor activity, learners discover the wonders of the habitat surrounding them.

Water Filter
Source Institutions
In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Deep Sea Diver
Source Institutions
In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

Seed Orbs
Source Institutions
In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.

Small Snails, Enormous Elephants
Source Institutions
This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

Handwashing Laboratory Activities: Fingerprint Technique
Source Institutions
In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

Make Your Own Weather Station
Source Institutions
This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

Scale Models
Source Institutions
In this activity, learners explore the relative sizes and distances of objects in the solar system.
