In term 4 the ideas for science club come from the students. It's no surprise that the first experiment request was edible slime.
As we discovered last week the slime everyone has been making is a polymer. This however is not edible. To create an edible version we used cornflour and gummy bears. When cornflour is mixed with water it creates gloop - a non-newtonian fluid. This time we mixed it with melted gummy bears to create a thicker malleable slime
As you can see in the photos below it was different from slime, more stretchy and stringy, but a lot of fun!
Making slime has to be one of the most popular experiments this years. Lots of children had made it before but didn't know the science behind it.
Here's how it works:
The glue is a polymer material. A polymer is a long chain of identical, repeating molecules. When we add the borax it changes the structure of the chain making the polymer thicker which then makes slime.
So using all the expertise in our club we made our own slime.
