Aim:

I want to find out what happens to Gummy bears when we put them into different solution.

Prediction:

I predict that they will dissolve into the solutions.

Method:

Equipment

 2x petri dishes

 paper towels

 marker pen

 Water

sugar water

Sugar water

Instructions:

1. Get your equipment.

2. Put on your safety glasses.

3. Using  the marker pen, write the name of the condition on the petri dish. DR

Discussion:

What is Osmosis?

Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane

Diffusion: The movement of any substance from a higher concentration to a lower concentration.

Conclusion:

The dry Gummy bear lost weight and was lighter after 6 days.

The Gummy bear in Normal water lost 1.82 gm in 6 days.

The gummy bear in salt water lost 1.2 gm in 6 days.

The gummy bear in sugar water lost 0.7 gm in 6 days.
