In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners investigate and compare the rate of drying in different conditions.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this outdoor activity/field trip, learners explore an aquatic site such as a pond, lake, stream, river or seashore to find and investigate plants and animals that live in water.

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.

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.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
