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

In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

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 explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

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

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 activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

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

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.

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.

In this activity, learners make self-assembled polymer spheres.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.
