|Prototype||Observations||Strengths for this Prototype||Limitations for this Prototype|
|Prototype 1:Noodle slime||The polymer was too stringy, it wouldn’t stick together and would fall apart, just like homemade noodles||The prototype wasn’t too sticky and was very stretchy.||It couldn’t stick together at all so when it would have to stick onto pans it would not work|
|Prototype 2:Noodle Slime 2||The polymer was very similar to the first noodle slime however it was thicker||It wasn’t very sticky||It could not stick together and was too thick to be able to stretch|
|Prototype 3:||This slime was too sticky and wouldn’t hold itself||It was very thick and sticky||The polymer was too sticky and wasn’t stretchy at all. It would break apart right away.|
Use evidence from above observations to complete.
Prototype # __4__, called _____Heat Reduct∞_______________, was most effective for meeting our goal because:
It was thick but stretchy and was sticky enough to attach itself to pots and pans, it was very durable and had a great grip.

What was the process like? What was challenging? What was interesting? What did I learn?
The process was very difficult for us. We wanted our polymer to be able to form around a person’s hand like a glove. We tried various ways to make the prototype perfect, at the end we had to give up. We had spent too much time trying to create the perfect prototype, so we needed to go with what we already had. We decided to ditch the glove idea and just go with a prototype that you could form into whatever shape you wanted. The reason why we chose this idea instead of one of the others was that this prototype was heat resistance. Instead of using it as a glove you could use it to hold hot materials, such as hot cups, hot pans, hot bowls, etc.. The new idea worked really well. We made a great commercial and I think we learned that we shouldn’t make everything so complicated because the simple ideas can often be the ones that turn out the best.
