Even more Newtons
Discussed Newton's laws of motion. Did four easy demonstrations today to as examples. These are easy and fun to do.
1) Blow up a balloon then let go and measure how far the balloon flies. It is difficult to get the balloon to fly straight so do several iterations.
Then blow the balloon up to the same size, add some weight, then let if fly and measure how far it goes. For weight, attach some coins or popsicle sticks. Putting the weight inside the balloon seemed to work better.
2) Put and empty baby food jar or similar container upside down over another identical container. Put an index card between the two. Pull the card out fast enough that the top jar remains on the bottom jar.
3) Put an index card on top of a baby food jar and put a large washer or a quarter in the center of the card. Pull the card out quickly. If you do it fast enough the quarter drops to the bottom of the jar.
4) Stack up at least six or seven quarters or large washers. Sharply hit the bottom quarter with a plastic ruler. The bottom one or two quarters will go flying off but the remainder of the stack should just drop down with out scattering.
Which laws are being demonstrated here?
Each student is required to write a lab report on one of the above demos. Each report should include:
Student's name
Date
Title of lab
Purpose of lab
Hypothesis
List of materials
Outcome of the lab
Discussion of results-what went right, what went wrong, what could be done to improve results
What you learned
Sections of the report should be written in paragraphs with proper punctuation, grammar, spelling, etc. The English Comp lesson comes free with the Physics class!
Write in the third person, present tense, and active voice.
Here are a few photos.
