Liquid Layers

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.

Lighting

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 (...

Investigating Fluid Flow Using PlayDoh

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.

Hydrophilic vs Hydrophobic

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. ...

Fun with Fluorescence

This module allows students to learn about two physical phenomena: fluorescence and crosslinking polymers. Students will have the opportunity to add sodium alginate to calcium chloride to produce a cross-linked polymer, calcium alginate; this is unique because students can take two liquids and make an insoluble gel.  Furthermore, one of the sodium alginate solutions contains liquid highlighter dye, so students can observe fluorescence by placing those with highlighter dye under a black light. In particular, this module covers concepts of chemical bonding and the absorption of light as...
