What have out scientists been up to?

7E Science – Changing States of Matter experiment.

In Science we are learning about the states of matter and how they can change state. Today we were observing how the ice changed from a solid to a liquid and then to gas. 

We added 5 ice cubes to a conical flask, placed a balloon on top and heated it using a Bunsen burner. As the water was heated and started to boil, the particles gained energy, which caused them to move faster. Eventually, the force of attraction between the particles could no longer hold them together, causing the water to change from a liquid to a gas. This caused the balloon it to inflate.

7SCIE conducted a science experiment, which involved investigating changing states of matter. We melted ice (a solid) in a conical flask, which changed into water (a liquid), which then changed into water vapour (a gas). This caused the balloon to inflate. 

We had lots of fun!!!!!!!!

7E Science – Changing States of Matter experiment.

In year seven we are learning about the particle model and the changing states of matter. Our experiment today showed changing states of matter in a simple and easy-to-understand way. We had a balloon attached to a conical flask and ice was inside the conical flask. We heated it until the water boiled and turned into water vapour. After this we let the equipment cool down. Once cooled, we ran the flask under cold water and the balloon deflated. This is because of the temperature changed the water vapour and it became water once again.
