P5/6 & P2/3 Science Experiments

British Science Week: Experiment Time

5/6, along with P2/3 explored osmosis through experimentation.

Firstly the pupils enjoyed learning about solids, liquids, and gasses where they made a human solid, human liquid, and human gas.

Solids consists of lots of tiny particles packed close together:

Liquids consist of less tiny particles which are spread out:

Gasses consist of the least tiny particles which are spread out even more:

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 transfer from a region of high water concentration to a region of low water concentration.

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 solution of water and lots of salt
  • placing the gummy bear in a solution of water and lots of sugar
  • 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?

P5/6 explored water density through experimentation.

As a class, we discussed the experiment before each pupil wrote down their own hypothesis of what might happen.

We discussed different variables before carrying out the experiment such as volume of water, how many spoonfulls of sugar, and volume of food colouring, to ensure that we could ensure an accurate comparison. This involved good communication and team work to ensure we got it right.

The final stage of our experiment was to observe the results and discuss why we thought this happened. When we poured each of the separate solutions into one main beaker, we saw the different coloured solutions ‘layering’ in the beaker and Joey was able to explain that he thought this was due to the density in the solutions (with each solution having a different density due to the amount of sugar that was dissolved in each). 

Super work P5/6!
