Monday

We went into the lab and started an experiment to learn about osmosis and diffusion. We take shell-less eggs and put them in water, corn syrup and a salt water concentrate. We will record the eggs weights starting and then every day. The students will also put a shelled egg in vinegar water to observe that.

Diffusion is when molecules move from an area of high concentration to lower concentration. Osmosis is the diffusion of water molecules.

We also reviewed the jobs of cell organelles. Students then were asked to write the cells jobs without looking. This will help prepare them for their test.
