In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
