In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.
