This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
