Germination Station
Source Institutions
In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.
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.
Breaking the Tension: Surface Tension 1
Source Institutions
Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.
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.
Runaway Runoff
Source Institutions
When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.
Super Soaking Materials
Source Institutions
In this activity, 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.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Window Under Water
Source Institutions
Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
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.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Clear Water, Murky Water
Source Institutions
How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
Giving Water the Treatment
Source Institutions
In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.
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.
