In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

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

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

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