 My Blog! We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world. Mr. G's Blog Mr. G's Class Facebook Page

Elastic Force of a Stretchy Rubberband

Did you know that elastic force of a rubber band doesn't follow patterns? I did. My class and I did an expirment to measure the elastic force of a rubber band. We measured it in Newtons! If a rubberband is stretched 2 cm, it has the elastic force of 1 Newton. If you pull a rubberband back it can pull a certain amount of elastic force (measured in Newtons of cource) If you accidently let go of the rubberband, it will snap forward because the elastic force is being forced to be pulled back. If you pull to hard, the rubberband can break because the length the band is pulled can be too much to handle. In some cases it makes the rubberband extremely weak because it was stretched too much.
