In our rubberband experiment we learned that with one rubberband it took 1,320 grams to snap one rubberband. We concluded that it would take 2,640 grams to snap two rubberbands. But we soon learned from another group that they snapped two rubberbands with less than 1,320. We then concluded that instead of putting the heaviest wieght you could on the rubberband that you would have to put fragments of wieghts and then but heavy wieghts on. This is do to Elasitisity which is do to an object being able to expand and return to its original size.
What did we learn in the rubber band experiments?
We learned that force can be pushing and pulling for example, when you push a door the door uses a force to push it the door pulls, or when you lean on a table you push force on the table and the table puts force on you.
We learned that rubber bands are made differently and no rubber bans are exactly the same. Some rubber bands stretch farther then others. When you are weighing rubber bands and adding mass constantly to see how far they can stretch before breaking the rubber band tends to snap quicker if you start off with a large amount of mass then gradually adding mass little by little so the rubber band stretches enough so it can get longer and longer which would make the length of the rubber band greater.
Yes, we have determined that if you gradually add mass little by little the rubber band can stretch farther than if you started with a large amount of mass it would tend to break quicker.

What did we learn in the rubber band experiments?
We spent a lot of time in the last week working with rubber bands and studying forces.
What did we learn about force?
What did we learn about rubber bands?
And, most importantly, have we determined any relationship between the mass of an object and how far a rubber band will stretch with the added mass?
