math instruction, that is.Actual weight of my van... more like 5500 lbs., so we were off by a bit. Can you figure out our mistake? Leave your hypothesis in the comments section below, and add it to your SJ notes from today.
2. Finish the Foot Pressure lab, answer the questions, turn in on Thursday.
3. Choose a demonstration to present to the class on Monday. Email me your choice, because the first one to choose a particular demo gets it. Also let me know if I can help with supplies--although mostly you should use your own household items. The subject is Air Pressure, and I want you to try able to explain the how and why of your demo to the class, in terms of kinetic particle theory. (All matter is made of particles, in constant random motion, colliding with each other and with the walls of their container.)
Here a site s to check out: http://www.thehomeschoolmom.com/top-ten-air-pressure-experiments-to-mystify-your-kids-using-stuff-from-around-the-house/
- Or Google "air pressure demonstrations"
- or YouTube it
- Remember to email which demo you choose; first come, first served.
4, watch this video, in which a physicist explains why the tanker collapsed, and write down that explanation in your journal on the page about the crushed can & cartoon strip. (last Monday's lesson)
Laura's hypothesis, if we tried to get exact measurements then we failed.I think we were not exact on measuring how much of the tires are touching the ground. By the way can I do the Magic Water Glass Trick? Laura
ReplyDeletecan i do the fountain bottle ths is alek
ReplyDeletehey mrs harmon can i do plumber magic
ReplyDeleteWe might have gotten the wrong area/surface area/perimeter of the wheels, which may have contributed to the wrong answer.
ReplyDeleteOr we forgot to half our answer (I don't know if that's part of the equation,) but if we halved our answer, we would have been close/closer.
Also, can I do the magic water glass trick?
ReplyDeleteIll take flying papers
ReplyDeleteZachary's hypothesis- The air pressure gauge was not accurate, which effected the calculations.
ReplyDeleteEthan-
ReplyDeleteI don't think the pressure gauge was on correctly causing the pressure to be to high or to low.

ReplyDeleteidk about measurements or pressure, they both sound right, but maybe it was a reading the gauge thing? also, i would like to do the water glass thing, bc the instructions on the others were kinda unclear
ReplyDeleteor the ballon and jar experiment
ReplyDeleteMaybe we rushed a bit, so all of the calculations were off by a little bit.
ReplyDeleteI might do the Fountain Bottle, is that okay?
ReplyDeleteNiles -
ReplyDeleteI think that, as other people have said, that the air pressure gauge was not correct and I also think that we could have got more exact when messurring the surface area
