today in science we made a Foss plan. first we used Popsicle sticks and sanded them down until they were the right size. Next we used straws to put the plane together. After that we had to staple it all together.

After we put the plain together we tested the Foss plane. We had to put the plain on fishing line so we could test it. After we put it on the fishing line we had to see how many winds it took to get the plane to the other side of the string. Then we had to see how many winds it takes to get to the middle of the string. when we did I that noticed that the number of winds it took to get to the middle is just half the winds to get to the other side.

I learnd that you can't change more than one variable at a time
