Hello I am a preservice teacher at IPFW. I am teaching a lesson about solids and how they can change state of matter and how somethings are soft solids. Is their anything you can share to help me better prepare for this lesson coming up

Hi, I am a student teacher in first grade and we did a unit over solids and liquids. Students always like being involved to if you could be hands on with them I am sure that they would enjoy that as well as stay engaged. I am sure that students would like if you brought in soild and liquid objects such as rocks or water. Teaching about solids and liquids is a fun unit, when you are finished with your lesson you can have students complete a sort to check for student understanding. Hope this helps!

Hi Spencer - I am also a pre-service teacher and taught a lesson about states of matter a couple of weeks ago. My lesson focused on the three states of matter and I had the students do an initial sort of materials I had gathered, to think about how they would group those materials. I then had them watch a video that discussed the three states of matter and do a re-sort. It was really interesting to see them puzzle through how they would group materials. However, in my case, I wanted them to think of solids as something that did not change form - to distinguish solids from liquids and gases. You might consider doing something like I did. Or, if you want to do something that demonstrates the changeability of solids, you might consider using ice. I hope the lesson goes well! - Julie

I great soft solid would be Play-Doh! Kids can roll it and play with it, or mold it into different shapes. Also you can have them experience Oobleck. Oobleck is a non-Newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands. It is a little messy, but can easily be washed away using water.

Ooblek is a great activity to do with kids exploring states of matter. I used to do this activity with third graders and they loved it. I encourage you to give it a try.
