What I've learned from:
1. Website http://www.bbc.co.uk/schools/ks2bitesize/science/materials/
Explanation: I have learned about changing state. We can change solid into liquid by heating, liquid into gas by heating more than 100 degrees Celsius, gas to liquid by cooling. We need to boil dirty water because it has bacteria.
2. Website http://www.sciencekids.co.nz/gamesactivities/gases.html
Explanation : I have learned about solid, liquid and gas. The solid objects are ice, sand, and wood. The liquid objects are syrup, milk, and rain. The gas objects are helium and steam. When liquid is heated, it changes into gas. Gas spreads easily. If we remove the lid of the beaker that contains of gas, the gas goes out.

Explanation: I have learned that molecules in solid move very slowly. Heat causes the molecules in a solid to move quicker and change into a liquid. In order for water to turn from a liquid to a solid, it must hit its freezing point of 32 degrees Fahrenheit.
