I used a ruler and I put a metal disc on one end then put a plastic chip on the other side and the metal disc was the heveset.

I agree the plastic chip was light and the metal disc was heavier.

I agree because when something falls faster than another item that means the one falling faster is heavier and vise-versa.

Me and Abraham's claim was the plastic coin weights least amount and the metal coin was little amount heavier.Our support is when I tried to blow the plastic coin it moved little bit but the metal coin did not even move.

Me and Shruthika's claim was the plastic coin weighed less the wood square median and metal coin more. Our support was we blew the plastic coin and it moved fast the wood square moved slow and the metal coin barley moved👾

I agree with you because I think that the heavier object the metal disc was harder to blow because it has way more wait than the plastic coin.

We compare weights without using a scale by making our own out of a dry erase eraser,a rular,and our materials we were given. How we did this was, we put the dry erase eraser on the bottom/table. Then,we put the rular on top.

Next, We experimented. We put the materials we were given on the scale ,and from that, we figured out that the metal disk was heaviest,the wood was next,and the plastic disk was lightest.

We compared by using objects that we usually don't use without a scale.We tryed then vignesh gave me an idea then I put three markers on the floor and put a ruler on top of it and we put a object on each side and started weighing and put the metal disk on one side and a wood piece on the other side the metel disk went down

I dropped the metal disk and it made the lowest sound so it must be the heaviest and when I dropped the wood it made a sound that was not very loud but not very soft either so it would fall in the middle and when I dropped the plastic disk it made a very high sound so it would be the lightest.

I agree because when I balanced the ruler the the side with the metel disc tipped and fell so I think the metel disc weighs the most.

On one side and plastic chip on the other side of the ruler and the metal disc fell down,and when we did it with wood square the metal disc still fell down.Then we put the wood square one one side of the ruler and the wood square fell down when we did it with the metal disc the metal disc fell down.When we put the metal disc on one side of the ruler and the plastic chip on the other side the the metal disc fell down

My group and I had the idea to have a group member to blow the objects, such as a piece of light wood, a small metal disc and, a small plastic disc,so then we had a group member blow each item and see which one went the farthest, first we tried the plastic disc,it went the farthest, then we tried the piece of wood it went below the plastic disc, and finally we tried the metal disc it didn't budge.

Claim,we fixers out that if you put the metal disk and the cardboard to balance it will be the same weight but if you take out the cardboard and put the plastic disk the metal disk will be more haver because the metal disk has more gravity then the plastic disk but if you put the cardboard it will still be the same weight.

My claim is the metal disc weight the most and the plastic disc weigh the least and the wood was just right.My support is when we used the big paper when the metal was on one side and the plastic and wood were on the same side,it was even then the metal made its side fall down.Then when we used the wood on one side then the plastic on the other side of the wood it was even for a second then the wood took more power but when it touched the ground it kind of turned back even,but the plastic disc weigh the least and the wood just right out of all of them.

So we made a kind of a scale out of a ruler and a small dry erase eraser and we put the ruler on top of the eraser and waited until the ruler stayed still and we put the metal disc and the plastic disc on top of the ruler we saw that the metal disc is heavier.

I think the metal piece is heavier because it was the hardest to blow and the wood was easy and a little hard to and the plastic was the only easy one and when we got a ruler and a pencil we put the ruler on the top of the pencil and got a wood piece and a plastic I put one on one side and the other on the other side the wood side was just a little bit heavier than the plastic and if we scorched the wood piece a little to the middle the plastic and the wood will be the same weight but really the wood piece is heavier than the plastic and the metal piece is heavier than the wood and the plastic
