Subtraction Games, Inferencing, Sinker or Float Experiments

Inferencing

I can make inferences when I read:

This week we will be reading new nonfiction articles about Nova Scotia's Geography. From these articles, after reading multiple times and making think notes we will be challenged to make inferences.

Sinking and Floating

Today we were challenged with making something that sinks float. We had to hypothesis about what we were going to do and why we thought that might make the plasticine float:

Ask me what designs I tried, if they worked, and if they did not what I would try next time?

We decided that shape, size, even and stable walls, hollowness and no holes all helped make a successful floater.

Next we were challenged to make a floater sink!!

Through classroom discussion we agreed to try adding weight to our floaters to see if we could sink them this way. Ask me how many marbles or objects until my floater sank? Ask me some other ways I could have made a floater sink besides adding weight?
