Aim:
The aim is to find out what happens to Gummy Bears when we put them into different liquids.
Prediction:
I think that the Gummy Bear might absorb some of the liquids.
Method:
The method we are
Equipment
Three solutions - water, sugar and salt
Four Gummy Bears of the same colour
Two Petri Dishes
Marker pen
Electronic Balance
Measuring Cylinder
Beaker
Steps
Get your equipment.
Label Petri dishes with DRY, WATER, SALT WATER, SUGAR WATER
Weigh the Gummy Bears and record their weight on the Petri Dish.
Add 40mL of the solution into the Petri dish.
5.46 - Gummy bear - Salt petri disc (Without liquid)
5.37 - Gummy bear - Water petri disc (Without liquid)
Findings:
Weight change
Water Absorbed by Gummy Bear
How many mL left in the petri dish?
Water Absorbed by Gummy Bear?
Why did the dry gummy bear lose weight?
Why did the normal water gummy bear absorb more water?
Why did the sugar water gummy bear absorb less water?
Osmosis - what does this word mean?
