In this activity, learners work in teams to study the observation skills essential to scientific research.

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

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

This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

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

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

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

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

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

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.
