This lesson will be the introduction to osmosis. The students will be divided into pairs. Each pair will be given a slice of eggplant and some salt. Students will sit at lab stations of four people to a station. They will have a discussion with their lab groups and develop predictions about what they think will happen to their eggplants after pouring salt on them. They will then record their predictions on their lab sheets. Students will also draw what their eggplants look like before they add the salt and what they think is happening to the cell membrane before the salt is added. Students will then pour the salt onto their eggplants. They will record their observations every five minutes in order to see how the eggplant is changing. Students will discover that the eggplant begins to release its water and shrivel up after about ten minutes because the water is pulled out of the cell by the process of osmosis. The salt sprinkled on top of the eggplant dehydrated the plant by drawing the water across the eggplant cell membranes and out of the eggplant. The kids will then be asked what they thought happened. We will discuss the kids' explanations as a class and write their ideas on the board.
