They were
- Barley
- Porridge
- Rice
- Cornflower
- Jelly powder (strawberry)
At first I prepared cold and hot water plastic cups and placed barley there. Barley is not dissolve in cold water but it swells up in time left in hot water for 30 minutes.
Second was porridge and after being placed in cold water it did not dissolves, but swells up in hot water left for 30 minutes.
Third was rice and it did not dissolve in cold water but after being placed in hot water and left there for 30 minutes it swells up.
As a fourth I was testing cornflower. Cornflower mixed nicely in cold water and dissolve but after being mixed with hot water it thickened the water.
As a fifth and last I was trying to dissolve gelatin, actually strawberry jelly powder, which not dissolve in cold water leaving transparent flakes in pink water. After mixing in hot water, however, it dissolved completely. I placed the container in the fridge for 3 hours as producer recommended and after that time my jelly become solid.
Unfortunately my mum camera did not work and we wasn't able to take any pictures, but we are planning to do some more tests over the weekend and then I am going to add pictures.
