Last week our Year 3 class finished their year with a lesson experimenting with chromatography using skittles. We placed the skittles around the outside of plates and pour warm water over them. We watched very excitedly as the colours all merged in the middle. After that we did an experiment to make crystals, an experiment that we have been waiting for all year. We are still watching our crystals now. we discussed how they might form in small groups. Our favourite thing, however, was making slime at the end of the lesson. We all had a go at mixing the ingredients ourselves and watching it form.
