Butter Making Experiment Worksheet

Science experiments lesson 17: Butter from shaking cream · Set 225 · 40 questions

What you do (Shake till it clumps): 1. Fill the jar only one-third full of fresh cream. 2. Screw the lid on tightly. 3. Shake hard, taking turns, for 10–15 minutes. 4. When lumps form, pour off the buttermilk and rinse the butter in cold water.
