Short activity: Density Rainbows

The purpose of this demonstration is to expose students to the principles and applications of variable density (as is relevant in many scientific and engineering fields). In this hands-on demonstration, the students will be carefully layering different concentrations of colored sugar solutions to create a colorful demonstration of how solutions …

Bulding an Endoscopic Surgery Tool

In the hospital, doctors use endoscopic tools to perform minimally invasive surgeries on patients. These tools are developed by biomedical and mechanical engineers, who consider the difficulties that might arise for the surgeon, such as tight spaces or limited movement. Students will recreate this design process through erector sets or …

Automated Programmable Garden

In this activity, participants design an attachment for a flower pot, complete with water sensors, irrigation pump, and red LEDs to help the plant grow. For the control of this “Programmable Garden,” participants will program a microcontroller (a simple computer) called an “Arduino” - the “brains” of the garden.

There is …

Short activity: Electrochemical Cell

In small groups the kids will be designing and assembling a water electrolysis device. In principle, the “device” uses electricity from a battery, to electrochemically separate water into its constituent components (hydrogen and oxygen). Each group of students will be supplied with a plastic, transparent cup, two electrode leads (insulated …
