blog due friday

in class we are doing a project with a marble and some supples.

Mission:
we must create a roller coaster made out of stuff like paper towl rolls tape sticks different kid of supplies. Easy right?
NO!! we must buy our supplies with what we call omega money that you earn from the teachers but doing good deeds being nice helping people etc. You must have 4 hills and one difficulty like a tunel a lube something like that. The marble will be acting like the roller coaster cart and when my group was done we tested it out and it workd it might not seem hard but it actually is. You dont know if the marble will get enough speed to go over the hills or through the lupe (if you have one) you should try it at home and see if you can comeplete the mission!!!

Blog # 2 (due monday)

In school we made a transverse wave that we useed with sand heres how:

You get a cup with a hole in the bottem but not to big and then you get about 3 peices of paper that are togeather and you need to tie the cup to something so it sways back and forth to make the wave of course your going to need sand though. In order to make the wave you have to move the paper. Your wave should look something like this:

but it will be on paper and it will be sand. Then you will have to trace it with a pencil. Then label it it now should look something like this:
