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 in an attempt to create a multi-layered rainbow …

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 …
