Science: Gummy Bears
Firstly the pupils enjoyed learning about solids, liquids, and gasses where they made a human solid, human liquid, and human gas.
In a solid, particles are tightly packed.
In a liquid, particles are less tightly packed and free to move past each other.
In a gas, particles are spread out and move randomly.
Experiment time:
P5/6 created hypotheses of what might happen when we placed a solid (gummy bear) into a liquid (water) and left it overnight.
P2/3 led the learning by showing P5/6 what to do.
We left the cups containing our solid and liquids overnight to investigate today. When we returned the gummy bears has gotten bigger. We learned that this was due to a process called osmosis where water molecules travel from an area of high concentration of water to an area of low concentration of water.
Finally, we discussed how we could use this knowledge to remove the water from the gummy bear. Some hypotheses we have put to the test are:
- placing the gummy bear in a saturated salt solution
- placing the gummy bear in a saturated sugar solution
- placing the gummy bear in just salt
- placing the gummy bear in just sugar
Why don’t you ask your child about the final outcome?
