Today’s lesson is posted to Google Classroom. I will be slower with answering questions and giving feedback today, so please be patient. Remember, our goals is to just try and learn what we can while we are apart. Your first priority should be to your health, your safety, and the health and safety of your family. I will copy the text of the lesson from Google Classroom below:
The demo from yesterday is a classic demo on surface tension. Here are a few more things you can do by playing with soap and water: https://www.youtube.com/watch?v=WsksFbFZeeU (I’ll copy the link below too)
Click the Google Doc below to create a document that you can answer the questions on (it will automatically share it when you turn it in). Also, if you change the color of the text, or use italics, it will help me when I read it. Thanks!
How is experiment 3 similar to the demo from yesterday? How is it different?
How could you design a demonstration/experiment to prove the boat moved because of the soap, and not just because the Q-tip made waves in the water?
Insert a drawing into your document to model what you think soap does to make the pepper/boat move across the surface. (You can insert an image of your own drawing, or draw with the computer using “insert–> drawing –>+new. Use the line scribble tool to free hand draw)
What other questions do you have about the video?
BONUS: Describe any other experiments you could do to help us answer questions about these demos.
BONUS BONUS: If you can record yourself doing some experiments, I will figure out how we can share them and learn from them
