Lesson Planning
Teaching
- Understand the arrangement of particles in different states of matter.
- Describe the changes in state seen in ice cream and chocolate sauce.
Activities
- Use a data logger to record the temperature of water in a jug before and after the addition of ice (Yrs 3&4).
- Play an active game to simulate the arrangement of particles in solids, liquids and gases (Yrs 3&4).
- Observe and record the changes in state in a dessert of ice cream and chocolate sauce by making an annotated drawing (Yr3) or writing an explanation (Yr4).
Investigation - exploring over time
The café staff want to serve foods and drinks that show people how materials can change state. Use a thermometer to measure the temperature of hot soup as it cools and ice cream as it melts. Freeze some fruit juice to make a slushy. Use data loggers.
Year 3 - Use given key vocab e.g. melting, cooling, freezing in a scaffolded task.
Year 4 - Explain findings using key vocabulary.
