This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this online activity, learners discover how random variation influences biological evolution.

In this online activity about heart disease, learners will pick one of three patients (based on actual patient histories) and help a cardiologist diagnose and prescribe treatments for him or her.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.
