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 investigate color vision as well as plan and conduct their own experiments.

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.

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 investigate the olfactory system by conducting several experiments.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.

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 discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners conduct the "Stroop Effect" test and explore what happens when they try to complete two simple tasks at the same time.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.
