In Science this week, Year 5’s CSI team have been trying to discover what substance was put into Professor Brainstorm’s tea.
Continuing with our topic of properties and changes of materials, we looked at how to separate mixtures using sieving, evaporation, filtration and magnetism processes. The children also established that some changes are reversible and irreversible.
It turned out that someone had put sodium chloride in the professors tea… the investigation is ongoing. Check back next week for any case updates!
