In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this quick activity about size and scale (on page 2 of the PDF under What's Nano?

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.
