Home Water Audit
Source Institutions
This activity offers learners and their families several ways to raise their awareness together about home water.

The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

Planaria Fishing
Source Institutions
In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

Build A Bee Bath
Source Institutions
In this activity, learners use found natural materials to create a water haven for bees and other insects.

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.

Soil Density
Source Institutions
In this activity, learners will test soil content using their sample, some water and a container that seals.

Frog Eggs
Source Institutions
In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

Do Plants Need Sunlight?
Source Institutions
In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

Sock It To Me
Source Institutions
In this activity, learners discover how sweating makes us feel cooler. Learners put on one damp sock and one dry sock and sit in front of a fan.

Make a Friend from Soil and Seeds
Source Institutions
Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.

How Animals Stay Warm
Source Institutions
In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

Veggies with Vigor
Source Institutions
In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

Root Beer Float
Source Institutions
In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Clean It Up
Source Institutions
In this "Sid the Science Kid" activity, learners get their hands dirty by playing in a container of soil. Then they compare the effectiveness of cleaning their hands with just a paper towel vs.

Make Your Own Sea Otter
Source Institutions
In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.
Soil Secrets
Source Institutions
In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.
River Catcher
Source Institutions
In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.
