She talked about different states of water- solid, liquid, gas. Ice is solid because it doesn't change shape, water is liquid because it can change shape and moves freely while steam is gas and is free to move around in the air. We pretended we were water molecules in different states.
In our first experiment, we had to put our finger a jar of water. Our finger looked bigger in the water than out of the water. Sally told us that this is called 'refraction'. Refraction is the change in direction of a wave caused by the change in the wave's speed, in this case water.
In our next experiment we wrote 'x' on a piece of paper and put it under a jar full of water. When we looked at the jar from the side, 'x' had 'disappeared' like magic. Water can play a lot of trick on us!

Another experiment involved some pepper. Sally sprinkled some pepper on the water and she told us that water can have 'skin' on top. The pepper floated on the top then she added some soap. The soap was heavier so it sank to the bottom creating a white surface. Sally then added some water and as if by magic, the 'hole' was filled up.
We also had a boat race with soap chasing the boat.
We had a challenge too! Our challenge was to add as many popping corn as we could to a jar full of water and count each time we put a corn in. We were able to put 56 corn without the water spilling out! We could see that the water was higher than the brim but it hadn't spilled, we wondered how many more could it take?
Room 6 looks like you had such fun playing with water and learning all about it. I really like playing with water also and especially swimming in water
ReplyDeleteSally taught us a lot about water, some things I did not know. We all are always learning.
