We have been looking at why things sink and float.
It is amazing what happens in nature.
This week we checked our prior knowledge, you know, what I already have in my mind.
Our next step was to make some predictions about why a rock sinks , bone floats, why a ten ton ship doesn’t sink and a ten ton ship submarine does.
We tested a solid ball, spoons inside a bag, little rocks, a bead, clay, paper towel, a bark and a spoon.
I wondered what other mystery will we learn about in our science next week.
