Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
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.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Moving On Up: Capillary Action 1
Source Institutions
Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Use Clues to Solve an Ice Mystery
Source Institutions
Learners explore the variables that affect the properties of ice and the places where different types of ice are found.
Moving On Up: Capillary Action II
Source Institutions
Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
Crumple a Watershed
Source Institutions
Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
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.
Forces at the Nanoscale: Nano Properties of Everyday Plants
Source Institutions
This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
