Have the video 6th - Unit 1 Lesson 8 Peppermint Candy in Different Water OSE loaded on your computer for day 1.
Setup Day 1 Food Coloring Lab:
The night before the lab, make ice cubes or refrigerate a pitcher of water to chill water to 6℃ (enough for 250 mL per group).
Set out a pitcher of water overnight to bring water to room temperature at 22–24℃ (enough for 250 mL per group).
Prepare an electric kettle to heat water to roughly 50℃ (enough for 250 mL per group). Note: Do not heat water to more than 55℃ or it will damage the plastic cups.
Each group will need 3 9-oz plastic cups, 3 drops of food coloring, and 1 cup measuring cup/8 oz. or 500-mL beaker to measure water for the cups.
Safety: Warn students about handling hot liquids. Be sure to have one pair of safety goggles for each student when using hot water.
