Team GCM Member and Field Trip Educator, Essence, is our handy-dandy chemist today to teach you about the chemistry of handwashing. Essence will tell you all about polar and nonpolar molecules in the handwashing process using LEGOs, then get into a fun polar/nonpolar art demonstration, and a demonstration of great handwashing tips using paint!
Polar/Nonpolar Explanation Materials:
- Box of LEGOs with three distinct colors
Polar/Nonpolar Art Demonstration
- Whole milk (preferred) or 2% milk
- Water-based food coloring
- Dish soap
- Q-tip (optional)
- Shallow bowl or plate
Directions:
- Add the milk to a shallow bowl or plate until it covers the bottom. Using a light-colored plate or bowl can be helpful so you can see the colors more clearly.
- Add 3-6 drops of food coloring to the bowl. Be sure not to stir or disturb the plate or bowl.
- Dip the tip of your finger or your cue tip into some dish soap and place it gently on the surface of the milk.
- Watch as the water-based food coloring moves away from your finger or cue tip. Paint a picture using this technique and repeating it on different areas of the surface of the milk.
