I am still trying to find how to build a Simple Windmill.. but I also found out that roller coasters came up when I searched for Physics and Motion together... so any other ideas? I have a week and a half till I present the co op class help!
TM, motion experiments are pretty boring in my opinion. I am in the middle of rewriting the lab portion of MSP and this is what I have for motion (Newton's Laws and circular) 1st Law - spinning egg 3rd law - milk carton water wheel The second law is so hard to find stuff for - all I have for ideas is shooting marbles but I have not worked it out yet. You can buy those collision carts as well, but pricey. You could also have them make a Rube-Golberg contraption as a class - but it woudl be time-consuming.
This is great! It is a two step project! We have Motion this month and we volunteered for electricity in January our next class so the project will go good with from here to there type of sagwey.. I think. I am planning on getting about five or so of the wind up air planes as well. You know the kind with rubber bands? I figure we can show that the prop turns the rubber band .. this increases the velocity by turn... Johnny knows all the tech words to it thanks to yoU! He corrected me with my discription so I told him he can explain how it works. We are going to have them wind it like a couple times, and let it go. lack of motion causes it to stop. Motion being the prop. So the amount of times turned will equal the distance flown.. is kind of what I want them to work out as a lab... Then I was thinking the younger ones can make a pinwheel wiht paper brads and i pencil ... then they have a fancy pencil later too! I have the plastic kind of paper that you use with scrap booking that should work I think... what do you think?
http://www.all-science-fair-projects.com/project1200_57_1.html what do you think will this one using 3rd law of motion work with its explaination of my plane prop thing? ..
Yeah, that's a good one! I like it because it shows how the propeller will move the cart backwards - perfect 3rd law example!
Have you ever thought about building one of these things? This one's made only out of bamboo. It takes imagination more than anything else.
http://www.answers.com/topic/newton-s-laws-of-motion wow this guy is really great! I am so getting this stuff! WOW! Colorado mom and Steve check it out, is he right on? IT seems so easy!
http://www.plymouth.k12.in.us/Lincoln/science/chap08.pdf how do I copy from something like this? lol its the cal state science book ... I like how they explained the laws better here than the guy, he forgot a crucial informative statement!
The most profound discoveries are always the simplest! Bear in mind that, before the age of early discovery, no one had any idea of the order that underpins the universe. It seems so natural to us that this is directly proportional to that, or that this is related to the square of that, but why should this be? Why not related to the power of 3.12 or 4.56 or 17.01? It came as an eye-opener to discover that gravity, for example, depends on the inverse square of distance - or even one mass multiplied by the other. We read these things now in boring textbooks, but they were all profound discoveries. A little before Newton, Kepler's eyes must have boggled when he happened across his three laws. By the way, others had some idea of these things before Newton, but he saw a little beyond them and transcribed them into three simple laws. That's the sign of true genius.
you know every year with ds13 I get amazed how much I missed in Science in school!, Now to find that the public schools here have a pretty good handle on the information in thier standard book helps me not be so worried about what ifs, at least California HAS some information, whether or not they use it is another story...
