In this science lesson, we are investigating whether different types of chocolate melt at the same rate!
This lesson is intended to be accessible to children from reception all the way to year 6. The joy of an investigation is that the children can add their own ideas, or go off on a tangent, if it interests them to do so. It’s best if you can let them explore the concept without guiding too much. If you feel that your child needs them, there are some extension questions included.
You will need:
- Dark, milk and white chocolate (preferably bars with similar sized chunks)
- Large bowl
- Thermometer if you have one (for measuring water temperature)
- Observe that some materials change state when heated or cooled.
- Set up simple practical enquiries, using comparative testing.
- Identify differences, similarities or changes related to simple scientific ideas and processes.
- Use straightforward scientific evidence to answer questions or to support findings.
