In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

This is an activity about turbidity, or the amount of sediment suspended in water.

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s

In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this environmental health activity, learners investigate their own vital lung capacities.
