An astronaut carried a pot containing soil weighing 60N from the earth to the surface of moon. He kept it there and just before return from moon to the earth he weighed the soil there on the surface of the moon and found that it was only 10N.

lettuce experiment to demonstrate cell diffusion/osmosis.
Aim : How do materials move in and out of the cell?
objective: 1. students will use a lettuce leaf to discover the function of a cell membrane.
2. Students will look at a multicellular lettuce and make-believe that it is a one-cell structure.
3.students will try to figure out what would be allowed into a cell by predictions,observations and by explanation
4.students will do an experiment to show the movement of water into and out of the cell
5.students will be able to state that the cell membrane lets materials in and out of a cell
materials required : Three bowls,food colour,salt,black pepper,water,a large lettuce leaf
Do now : Based on the knowledge aquired
#1 Predict what would happen if you placed a piece of lettuce into a salt solution
#2 Predict what would happen if you placed a piece of lettuce into food colouring
#3 Predict what would happen if you placed a piece of lettuce into a mixture of water and black pepper?
#1 salt solution #2 water food coloring #3 Water Black Pepper
