yeah, i can help.  i can help you be a better parent by giving you some advice:  don't do your son's homework for him.  you are sending him to school to learn, aren't you?  how is he going to ever learn how to do anything if you spend days doing his work for him?  \n\nsure, he might end up with an A in first grade, but who cares about what you got in first grade?  you could make an argument that grades are important to his future if they are high school grades, but it's far more important that he actually *learn* things at this age.\n\nsheesh.

On 1 graph you could put age(x) and height(y).....and on another graph, you could probably put age(x) and weight(y)......I think :)

a) You have to draw gravity as a straight line down. Then you have to realize that gravity does no work if the block was on a horizontal surface. Work done by gravity is alway M*G*H.  The mass is 4.8 kg and the gravity is 9.81 m/s^2 .  The height will be sin (30) = H/2.  the sin (30 degrees) is 0.5 so .5=H/2.  the height will be .5/2 = .25 m.\n\nsoo you will have 4.8*9.81*0.25\n\nb) the work done by the frictional force will always be the frictional force times the distance.  The frictional force is going to be the normal force times Uk.  The normal force has components to it, so its going to be sin(30)*g*m.  The you need to multiply that by the friction coefficient and then by the distance traveled.  You will have 2*0.436*sin(30)*4.8*9.8\n\nc.  The work done by the normal force is just going to be cos(30) (i think) times 2 ( the distance traveled) times 9.81 (gravity) times 4.8 (the mass)

Are you do this project for yourself or one of your children? Go to your nearest "Craft Store" - there you will find all that you need, including the hundreds of "Popsicle sticks" you will need. Good Luck, and if I am correct and your doing this for your child, you need to speak to the teacher, this assignment is far to difficult for a Grade 3 student. The teacher should have started with a "hot plate holder" first! Have fun Mom!

Use cardboard, clay, or sugar cubs.  Cardoard would be the easiest.

You mean find "g" as if you didn't know the constant? Okay.\n\nPretty simply really. Have the height measured that you're going to drop it from to where it's going to land (this will be your "h"). Make it a high one (one meter is enough). Measure the mass of the object (that's the "w"). Then when you do the experiment, time it. Start it at the instant you let it drop and stop it once it touches where ever it lands. That's enough information to find "g." Just solve for "g" then that would be the answer.\n\nActually, for an experiment, you should solve for "g" as a formula before you start doing anything else. So the formula would be like this:\n\ng = (2h)/[(t^2)(w)]\n\n(t^2 is "t squared")\n\nSo just have that formula then do the experiment: measure height of the drop, the mass of the object, then time it when you drop it (you need good reflexes when you drop it, as it falls fast).\n\nPS Penguins!!!

These are some ideas aimed for pre-k, 1st and 2nd grade:\n*you can provide different geometrical shapes and have them sort them according to color, size, shape, etc.\n*with the same shapes have them complete a pattern you start for them ex. red circle, yellow square, red circle, yellow square, etc.\n*try looking for a game called "Tangram", I don't know if you can buy one already done or you can make your own in this site:http://www.tangram.i-p.com/\n*give students play money and have them solve problems using it.

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

I am a former science/math teacher and science fair judge.\nunfortunately your question does not contain enough information for me to help you.  First look at the papers from school to see what is required.  Choose a topic.  Research the topic.  Do the project.  make a report (usually they require those boards that stand up on tables you can buy them).

use trusses. basically triangles. if u wanna do it easily, use 45 degree angles. to make it more stable use 30 and 60 degree angles. so basically make each side first and then to connect between them, i have no clue but dont do it straight across. u have to connect the top of the left to the bottom of the right. o rsomethin

My skateboard weighs 3.5 kilograms- I just weighed it. Standard double nose deck, independent trucks, Simms 94A wheels, no risers.

I dont think anyone is going ot do the work for you to build you a table, try looking it up on google.\n\nSorry

The following link has some good ideas for different projects. \nhttp://www.all-science-fair-projects.com/category0.html\n\nAlso, the following link might help you set up a science fair display board if you have to have one.\nhttp://www.sciencebuddies.org/mentoring/...\n\nA good elementary science fair project is testing the density of various liquids.  All you need is a tall clear glass or vase and various liquids such as... dishwashing detergent, mineral oil, corn syrup, olive oil, water (dyed blue), molasses, or corn oil.  Use at least five different liquids (of different colors... makes the project more attractive) and slowly pour them into the container.  Also, perform the experiment more than once adding the liquids in different orders and note your results.  This project is easy, but it is also very educational and helps to teach the basic concept of density.
