Experiment in progress

here are some pictures of me doing my experiment/ related stuff:


Rubber bands in experiment tray

and putting rubber bands in the oven.






15 rubber bands in each group

Putting another group into the fridge with same tray




Sideways oven :)

Aim and hypothesis

Not really sure if this is necessary because last time i heard it was just the method required...
anyways, here it is (By the way, this is meant to go before my method shown in previous posts)

Aim: To investigate whether temperature will have an effect on the load a rubber band can carry before rupture.

Hypothesis: Rubber bands heated above room temperature will be more elastic than rubber bands heated at or below room temperature.

For variables, see the post somewhere down there :)
