• Soap Bubble & Bottle Investigation - Prepare one empty 2-liter soda bottle (no cap). (2) Prepare soap bubble solution. Liquid dish soap should work, but if the bubbles pop too easily, try a solution of 8 parts water, 4 parts liquid dish soap, and 1 part glycerin. (3) Prepare one cold water bath: one 6-quart tub with approximately 3 inches of cold tap water. If the water isn’t very cold, add ice. This can be prepared ahead of class. (4) Have materials ready to prepare one hot water bath: one 6-quart tub with approximately 3 inches of hot water. If your school has a hot water tap, this is sufficient. If not, use the electric kettle(s) from the Energy Affects Matter Unit to heat the water. Water does NOT need to be boiling
