In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

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

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

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 use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.

In this activity, learners investigate how some butterfly wings get their color.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
