Seperating mixtures

When you mix things together, sometimes it is an irreversable change, but sometimes you can reverse the process. We looked at different mixtures and thought about how you would be able to separate them again.

We looked at the processes of filtration, evaporation, magnetic attraction and sieving in order to separate the mixtures.

Can you think of how these processes might be used in real life?

Science – Insulators

We have been looking at conductors and insulators this week.

We experimented to find out the best heat insulator by wrapping ice-cubes in different materials and seeing which ones melted the quickest.

We wanted to find out the materials that DIDN’T melt very quickly, this meant that they we good heat insulators.

We found that plastic and rubber were the best.
