Today we took one last peek at our eggs... WOW! Osmosis really does go from high to low (totally pulled the water out of the distilled water cups and watered down the sugar solution!).
We also observed the energy stored in food when we boiled water with the energy stored in just one almond! That energy releasing process in our cells is called respiration. We read pages 49-51 and took THESE NOTES (PRINT IF YOU WERE GONE AND PUT ON PAGE 75). Monday we shall explore the relationship between photosynthesis and respiration plus discover what cells do when they don't have enough oxygen to respire (it's called fermentation).
This is the last weekend to get work caught up from chemistry of cells and diffusion/osmosis.
