Enhanced Water Taste Test
Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

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.

An Ice Lens
Source Institutions
In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

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.

Straw Kazoo
Source Institutions
In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

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.

Synaptic Tag
Source Institutions
In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

Water Sphere Lens
Source Institutions
In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.
Moving Pictures
Source Institutions
In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

Diffraction
Source Institutions
In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

Hunting Minibeasts
Source Institutions
In this activity (p.6-10 of PDF), learners use different methods for hunting minibeasts (bugs). Learners can either make traps or simply look for minibeasts under stones and logs.

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.

Decibel Cannon
Source Institutions
In this activity, learners will construct an air cannon as a model for the human ear.

Kitchen Jamboree
Source Institutions
In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.
Breakfast Sweets
Source Institutions
In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.

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.
