Sadly, it seems we must delay racing our MTcars till after the holidays. I tried out a couple of them at the tennis court this afternoon, and it seems not to be as good as I had hoped it would be. Slightly sloped (so rain doesn't puddle) and too much friction, I guess. So we will wait. In the meantime, you may take yours home and fiddle, if you like, so long as you bring it back whole. I think all the cars would benefit from increasing the traction, using balloons or gluing rubber bands around the wheels. Reducing friction also, and aligning the wheels, shortening the string so it doesn't tangle or get caught on the hub may also need to be done.
Homework is the worksheet that was so difficult to print from last blog, but this time it needs to be completed, with the exception of where it asks for you to calculate speed, acceleration and momentum. (Answer the questions where it says "Application," and also the page of the 3 laws.) The worksheet does not leave sufficient room to answer the questions, so use a separate piece of paper, and write your answers in complete sentences. Type, if you can.
Also, if you did not complete the test, you need to do so as a worksheet and turn it in.
Thanks!
I already did the sheet a few days ago.
ReplyDeleteHey Mrs.Harmon,
ReplyDeleteIt's Abigail. I was just wondering how we fill out the application part, because we gave you the card that we filled out with that information on it, and I don't think I have a tool to calculate Newtons.
Hello Mrs. Harmon,
ReplyDeleteI do not have my mouse trap car to fill out the mouse trap handout. However, I may be able to fill out some things... ?
Thanks,
