The document describes an experiment conducted by Sara, Leila, Nina and Rhiannon to test their hypothesis that a boiled potato would not absorb water through osmosis like an unboiled potato. They cut a potato in half, boiled one half and left the other raw, then placed both halves in a salt solution to test if the boiled half absorbed less water. After waiting a day, they observed the results and drew a conclusion about their original hypothesis.

4. Hypothesis
We think that the boiled potato will not have water I it
And that the not boiled potato will have water in it

5. What is osmosis?
Osmosis is the chemical process of diffusion, involving the
transfer of solvent with a lower concentration of a certain solute
through a semipermeable membrane, and into the area
containing a higher concentration of that solute. It sounds like a
confusing concept to teach younger children just getting into
the sciences, but it’s actually quite simple, and can be
demonstrated with only a potato, some water, and a little bit of
salt

6. Materials
– 1 potato
– Water
– Potato peeler
– Salt
– Knife
– Petri dishes
– Something to boil it in
– Boiler

7. Method
– We cut the potato in half
– We boiled 1 half
– We made a hole in both of them
– We filled the Petri dish with water
– We filled both of the halfs with salt
– And then we wait
