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 activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

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.

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

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

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

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

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

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

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

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.

In this activity, learners are invited to imagine the park of their dreams!
