This half term, Year 5 and 6 have started a new Chemistry topic: Materials and their properties.
In this week’s Science learning, we learnt all about which materials are soluble (do dissolve in water) and which materials are insoluble (don’t dissolve in water).
We tested each material by placing an amount into a cup of water and observing whether they dissolved or not.
Independent variable: the material
Dependent variable: the solubility
Control variable: the amount of the material, the amount of water, time observed for, temperature of water
We found out which materials were soluble and recorded our results in a table!
Help at home: Ask your child to define: soluble, insoluble, dissolve, independent variable, dependent variable and control variable!
