Year 10 Academic


Chemistry students carry out lab tests to identify different substances.

Oh dear, some of the labels have fallen off the bottles in the Science lab and the technician no longer knows which solution is which? What can the students do to clear up the uncertainty and restore some equilibrium back in the lab?

Presenting the Year 10s with this hypothetical situation, Mr Smith handed them the tools and necessary equipment to carry out a range of tests to work out the differences between the various bottles of clear-coloured liquid.

The girls have been learning about different ions. They know how to carry out flame tests to identify positive ions and how to conduct precipitate tests to work out negative ions. This was their opportunity to bring the two together to identify the likes of sodium (it burns with an orange/yellow flame) and dioxide (it fizzes) and put the correct labels back on the bottles. Phew, confusion over.
