Jelly Baby Osmosis
What we did was we first got 8 jelly babies in 2 colours ( pink and yellow ) each of us got 2 per each person. We then got our petri dish and filled it up with either sugar/salt and water.
We took our jelly babies and placed to in each dish. There were 3 petri dishes in total for (Maddison, Ayla, and Me). Maddison used Water, Ayla used Salt, and I used Sugar.
Hypothesis : What will happen to the jelly babies in each solution?
Ayla : I think they will all expand but the water one will have the least growth
and the salt will have the most.
Erin : I think the jelly babies all with grow but the water one won't grow as much as the salt and sugar one,I also think the salt one will grow the biggest.
Maddison : I think they will grow but salt will be the smallest and sugar would be the
biggest and they would dissolve in the bath if salt,sugar,water ,i feel like the the jelly babies that
go in salt water will dissolve
The results were :
The salt one was falling apart when we moved it.
The sugar one felt the hardest and most put together but still a bit moshed.
The water one fell apart but not as much as the salt one.
Hi Erin
ReplyDeleteYou have described the experiment well. I like that you have included the hypothesis from all of your group. Did your experiment results prove them right or wrong.
Can you think of how you could get more accurate results?
Well done.
