The Magic School Bus Meets Molly Cule
Field Trip Notes
When Wanda's favorite singer, Molly Cule, comes to town, she chooses Ms. Frizzle's class to wash her famous car. The kids clean the car top to bottom, but Molly insists they missed a spot. Only when they shrink small enough to see molecules can they clean the car down to the very last bit - but time is running out, and they need a molecular miracle to get the job done before Molly's concert begins.
Time: 50 minutes
Group Size: 4
Ralphie discovers that soap and water slip grease and grime away because of the special characteristics of soap molecules. Your kids investigate some characteristics of oil, water, and soap.
What You Need
For each group:
Talk About It
Pass around samples of oil, water, and liquid soap. Ask: What are some characteristics of water? Oil? Soap? List responses. Ask: Do the teeniest-tiniest bits (molecules) of these things determine these properties? (yes)
What To Do
Draw timelines of the kids’ rocks. Decide on a time scale, and let kids give their ideas for: where their rock was a very long time ago and what it looked like; where it was found; where it will be and how it will look a long time in the future.
