In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

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

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

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this activity, learners will discover why there are holes in bread.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
