In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

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

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this activity, learners will use their chosen material to build the tallest tower possible in under three minutes. This activity uses problem solving and fine motor skills to challenge learners.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

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.

In this activity, learners will build the highest tower they can out of recycled materials.

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 activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

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