In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.
