Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

Learners draw pictures of how they envision scientists. By comparing and discussing the features in their pictures, they can discover common thoughts and stereotypes about scientists.

Pairs of learners play the roles of programmer and robot. The programmer gives specific directions to the robot to accomplish a simple task (e.g. walk across the room and pick up a pencil).

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.

In this online activity, learners partner up to complete several physical exercises and assess their starting fitness level.

In this online activity, learners measure their pulse rates and investigate how their pulses change when they engage in different activities.

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

In this online simulation, learners use antibiotics to cure patients with bacterial infections.
