We are taking advantage of our short week and hitting up our science unit in full force! We had the chance to get in four science experiments this week. The kids learned that there are 3 different states of matter: Solid, liquid, and gas. We talked about the different attributes that go along with each state of matter:
We also talked about changing matter from one state to another (solid ice cube to liquid water & liquid water to the gas water vapor).
At the end of our experiment, I gave them a new kind of matter to play with to see if they could figure out what form of matter it was. We got a little messy and played around- they noticed that the Oobleck had some attributes of a solid and some of a liquid! 🙂
This was so much fun and it was super easy. If you haven’t tried it before, it’s simple to try at home!
1 1/2 C. Corn Starch
1 C. Water
Food Color (optional)
Mix the ingredients and allow children to play with the mixture. When ”pushed” together, the mixture will appear dry and solid; as children let go of the mixture, it flows like a smooth liquid.
We also studied magnets. Each student and partner was given a bag with multiple objects inside. First, we went through and predicted if we thought the object would be magnetic or not, and then we went back and tested them all. We were a little surprised by some of the answers! The paperclip was magnetic, along with our scissors, but the penny was not. We explained that in order for an object to be magnetic, it needed to have something special called IRON in it. We went through our list of predictions to figure out which objects had iron in them!
The next thing we talked about was how magnets have 2 poles, a north and a south. The kids learned that opposites attract and the same poles repel, or push away from each other. We experimented with all different kinds of magnets to find out what poles were the same and what poles were opposite.
The last day, we turned into magnets! One of our hands had a “N” and the other had a “S”. We practiced a few times showing how we could “attract” to a partner by having a N and S together, or how we could repel from a partner if we both put up the same pole. Once we got the hang of it, the kids moved around the room to music and when the music stopped they had to listen for their direction to either repel or attract the closest person to them. We would continue and each time the music stopped- the kids stopped and thought about which hand to put up to show the proper magnetic response. 🙂
Another attribute of matter that we studied was sinking or floating. The kids really enjoyed investigating different vegetables and objects and predicted what might happen when these things were placed in water. We also created boats out of Play Doh. Many of our boats had the properties needed to make them float, some of them were sinkers.
