Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

Space Stations: Sponge Spool Spine
Source Institutions
In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Do Your Own Dig
Source Institutions
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

Composting
Source Institutions
In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

Fossils: Observing, Making and Learning
Source Institutions
In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.

Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.

Make a Dinosaur Model
Source Institutions
In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

Positive Planning Adds Up
Source Institutions
In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.
The Earth's Timeline
Source Institutions
In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

Wetlands
Source Institutions
Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

Spectroscope
Source Institutions
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

Rubber Blubber Gloves
Source Institutions
In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

Dinosaur Sock Puppet
Source Institutions
In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

Corals on Acid
Source Institutions
The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

Stream Table
Source Institutions
In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.
