Our lab today

I think that the lab today went very well. We stayed on task, and we cleaned everything up when the teacher said so, we also helped each other during the cleaning up time. But lets get back to the experiment. Well our experiment went very well. I thought that it was very weird that first you think it’s a solid, but then it turns into a liquid, so you don’t know if that is a solid or liquid. Also when you hit it quickly it is like a solid, but if you put your hand slowly inside, it is like a liquid.  In my opinion I thought that this mixture is a homogenous mixture because you can really see what it is made of. Also what we used was water and corn starch to make it. During our experiments I think that at some points it was too hard and at some points it was too liquidy. So if you have too much water then it is not good, and if you put too much corn starch it is too hard. After a wile of touching it, your hands get wrinkles on them. But this might be an absolute material, not solid, not liquid, but something ells???  

Here is a video so you can see it

  1. Good reflection. I like how you described the liquid or solid...actually, it's called a non-Newtonian liquid.
