Soap Making
Heidi Park | Sat, 07/08/2017 - 11:56
Heidi Parks offers a soap-making lab or activity that can be run in a chemistry class with 25-30 students working at the same time. She usually does this activity right before spring break, as it provides enough time for the soap to harden and cure (high school students are impatient to use their soaps right away, which you should not do with cold process soap). She has used this soap making activity at different points in the curriculum: during intermolecular forces, during acids and bases, and during stoichiometry.
Kool-aid, Cotton, and Intermolecular Forces

Red dye #40 found in strawberry Kool-Aid and various cloth fibers can be used in a very simple experiment that can teach students about intermolecular forces. A video is included that describes the experiment and analysis of results.
Punk Rock, Longboards and Mad Science

It all started with a class my son and I took together at Marc Adams School of Woodworking (link is external). To make a long story short, we started on a Saturday morning with nothing and left Sunday afternoon with a custom built longboard. (Think skateboard but...well...longer).
