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.

In this story time program, young learners listen to the Dr.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

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 (11th activity on the page), learners use pennies to test their hearing acuity.

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).

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
