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

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

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).
