In this multi-part activity learners examine non-point water pollution.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

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

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 outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

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

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

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 game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

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

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.
