Last week we took part in our first ever science experiment! We had to ensure we knew all of the safety precautions needed to work in a laboratory before beginning. This experiment focused on our knowledge of scientific vocabulary. We learned about a variety of meanings in science, and in particular we learned about the meaning of ‘soluble‘ and ‘insoluble‘. We now know that sand and iron shavings, may be two very minuscule pieces of solid matter, but as neither of them are a liquid, they will never dissolve. We spoke about how some chemical reactions are reversible and some are irreversible. we spoke about what tools we can use to separate some states of matter (e.g. drain pasta from hot water using a sieve). We were a very clever bunch, and realised very quickly that a magnet would work to separate the iron from the sand, as it is a metal. Here we are as scientists for the afternoon!
