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

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

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

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

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

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.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
