Tuesday

We checked on our eggs today. We have been studying diffusion and we are weighing the shell-less eggs to see if they are losing or gaining liquid. The egg in corn syrup lost almost 40 grams of liquid. The salt water egg gained 6 grams and the green water egg turned green and gained 4 grams. The shelled egg that we put in vinegar has lost its shell and is at 67 grams. We will weigh all the eggs daily and see what happens to them.

Today we discussed that living and dead things have cells, but non-living are things that never lived and so they do not have cells. However, living, dead and non-living things all have elements. We discussed the elements in the human body and the contents of the human cell. (B42-45)

We watched a Youtube on photosynthesis "Photosynthesis" by mediasemantics. Many students understand this concept so it was a review, but for some it was their first time through.
