Aim: To investigate the factors affecting the stretching of springs and rubber bands Scientific Knowledge: Before doing the experiment I came to the conclusion that this experiment relates to Hooke's Law which states that extension is proportional to the load, meaning that if you stretch something with a steadily increasing force, then the length will increase steadily too. By looking at various sources I have also found out that if a mass m on a …

…each other. This would have given a wider variety of results. To extend the experiment I could look at the elastic limit of different stretchy materials and add weights until the spring/rubber band does not go back to its original shape, by doing this I will be able to compare how much weight the different materials can withstand and what factors affect their strength by looking closely at the inter-molecular bonds within their structures.
