Spot the Difference

Changes are happening all around us. Chocolate melts in the sun, water evaporates from puddles and cement hardens in the open air. Predicting the changes that can happen to everyday materials is important in understanding the best way to manage things such as, food handling and cooking, construction and packaging.

Our Spot the Difference unit is an ideal way to link science with literacy in the classroom. By observing change, students glimpse the diversity of materials in their world. Students explore change through the context of food including spaghetti, chocolate and popcorn. Students learn about how heating or cooling a food can change its properties and whether that change can be reversed or not. An investigation about which type of chocolate melts the fastest will help students draw conclusions about how fast or slow changes can happen and the consequences of change.
