Experiment
Butter from a bottle
- ages 3–9
- 40 min
Children turn heavy whipping cream into butter by shaking a jar, then sample it on bread.
Steps
- Conversation: where milk comes from and what is made from it (cheese, yogurt, butter).
- Pour heavy whipping cream (at least 30% fat) halfway into a jar or bottle.
- Sitting in a circle, children pass the jar and shake it to a song for 10-15 minutes.
- Observe how the cream thickens, and then separates into butter and buttermilk.
- Spread the butter on bread and taste the buttermilk.
Tip: Drop a glass marble into the jar; butter forms faster. Check parents for dairy allergies.
Materials needed
- Large glass jar (1 per group)
