Students are challenged to recreate a tire that is missing from a Lego racecar using measurements that they take.  Students must first measure all of the dimensions of the tire that they need to recreate.  Then the model car and tire will be taken away, and the students will work with Crayola Model Magic clay to recreate the missing tire entirely based on their measurements. The students will then test the fit of their newly created part in the racecar, testing the size and movability of the racecar with their new tire by rolling it down a ramp and (optionally) measuring its...

In this module, the interactions between liquids of different densities are shown by placing multiple liquids in a test tube. Each liquid will "isolate" itself from the others, thus showing clear boundaries between different-density liquids! Additionally, solid materials of different weight (paperclip, bottle cap, etc.) will be dropped into the test tube to see how the heavier materials will sink into the liquids with higher densities.

The Lighting module introduces the concepts of energy and power through a study of light bulbs power consumption. Students determine the power consumption of different light bulb types and compare to the values indicated on the original packaging. Energy consumption is calculated by assuming an average daily usage and energy cost calculated based on current electricity rates. Other aspects of light bulb use are evaluated including: 1) luminosity, 2) dimmability, 3) lifetime, and other factors such as bulb hazards and color. Total cost of illumination is calculated from electricity (...

We teach kids about crystallization by making rock candy with them.

This module uses PlayDoh extrusion to generate and visualize the parabolic profile for flow of fluids through a tube. Participants make predictions on the pattern of the flow profile, collect data and calculate velocities. Follow-up questions allow those leading the module to debrief on what the participants observed.

After the demonstrations and activity students will know about the properties of hydrophilic and hydrophobic materials. To introduce the concepts, a demonstration of will be used, a “lava lamp” made with cooking oil, water, and alka seltzer. The topic of density will also be explored in the demonstration. After the demonstrations students will be able to participate in a hands on activity where they will take home their own art made using hydrophobic and hydrophilic everyday items. ...
