Are you able to relate what you learned to what you already knew?
Today we learned in lab that matter is made up of particles. An example of these particles is an atom. We then were able to connect what we knew about how atoms move in matter to bridge the gap in our knowledge about particles.
Which parts did you find clear and which were confusing?
While talking about melting I got a little mixed up. I understood that there had to be a phase change, but when we started talking about if a Lifesaver in hot water was melting or not. I initially thought of it as dissolving, but after explaining it, it felt like melting. Then after more discussion, we decided it was dissolving because the sugar was still solid, just not in the shape of a Lifesaver.
I have more questions about how we know how to distinguish melting and dissolving. It feels like the sugar in the Lifesaver was turning into a liquid, but I know it was still able to be separated from the water.
*We also got to meet Squirt!*
Hi Meredith! I feel like I often still get confused on the concept vs dissolving. One thing that helps me to remember the difference is that when something melts you can reverse it but it is much more difficult if it is dissolved.
ReplyDeleteI also thought that the dissolving/melting conversation was slightly confusing. It helped for me to remember that the sugar was just diffusing into the water and still was sugar particles, and also to think of it similarly to the m&m experiment. I think these connections would also help elementary students to understand as well.
ReplyDeleteHey Meredith, I also was a little confused on if the life saver was dissolving or melting. After our instructor kind of explained on if it was melting or dissolving is through the process of reversal.
