What did you learn this week?
This week we learned a lot more about matter and how to describe it. We also review what some properties of matter are. We discussed buoyancy, density, conductivity and other properties of matter. We applied our knowledge to experiments on M&Ms and how the water affects how they M&M dye spreads. We learned that hot water makes the dye spread fastest, with room temperature water second fast. The salt water spread decently fast, but all the colors spread into each other while all the other plates had separate colors.
Which parts did you find clear and which were confusing?
I didn't understand why the different waters with the M&Ms were causing the dye to spread faster, slower, or mix together. I think it has to do with a reaction with the salt or sugar in the water and the atoms of the dye, but I am not quite sure. I do understand why groups would time their experiments and take pictures every 15 second to watch and measure the spread of the dye.

Hi Meredith!
ReplyDeleteI like how you mentioned the heat makes atoms move faster so that is why the dye dispersed quicker. So it would make sense that the hat water is making the dye move quicker. I really like your illustration of density. Good job!
Hi Meredith, I really liked your post and thought that it was really well written. I liked the part where you talked about the idea that the hot water is what caused the dye to spread faster than it did in the room temperature water. This is not something that I had talked about before and now makes me wonder if cold water would cause it to spread slower than the room temperature. Nice job!
