Science and Math in FE8A

Today in science we looked at average density. This is, in case you weren't paying attention, or didn't take notes, something which we are all guilty of one time or another (but don't do anymore), is simply all the masses and all the volumes divided by each other.
In this diagram it shows the experiment that we did in class which illustrates average density.
1 to start this experiment we mixed baking soda and vinegar which caused us to end out with a bubbly liquid.
2 After we got our bubbly liquid we placed corn kernels in to the beaker causing the bubbles to form on to the kernels making them float.(lowering the average density)
3 Then when the kernels came to the top of the beaker the bubbles released into the air causing the average density to rise and the kernel sinks to the bottom. Then the process repeats over and over until there is no gas left to release.

Now to math.
In math recently we have been looking at angle proofs. tonight we had many angles to solve using all the rules. We will be having our unit test on Monday.
See you tomorrow
