In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity. There are three parts to this...

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of...

In this activity, learners are challenged to design and construct a jointed figure that moves in a motion (something like jumping jacks) when a string is pulled. Use this project as a culminating...

In this activity, learners build a figure that moves and "comes to life" when they pull its string. This engineering activity introduces learners to simple machines, specifically levers,...

In this activity (on pages 11-14 of PDF), learners cut out pictures from magazines of foods that help make bones strong and glue the pictures to a paper bone. The lesson plan includes information...

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways. By building their own pinhole viewers, learners make observations about the...

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans. In addition, learners discover how scientists estimate the...

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins. Learners discuss where these proteins are located...
