Chemistry in the Kitchen

Students will complete the red cabbage chemistry experiment to observe a chemical change. Then students will demo multiple recipes and classify the changes as physical or chemical, including: mixing a salad, making a smoothie, making popsicles, making sun tea, making pancakes, observing oxidizing apples, sauteing a vegetable.

Essential Questions

  • How can we observe and explain the differences between a physical and chemical change?

Standards Addressed

Focus
  • S5P1. Obtain, evaluate, and communicate information to explain the differences between a physical change and a chemical change.
    • a. Plan and carry out investigations by manipulating, separating and mixing dry and liquid materials and communicate collected data to demonstrate examples of physical change.
    • b. Construct an argument based on observations that the physical changes in the state of water are due to temperature differences, which cause small particles that cannot be seen to move differently.
    • c. Plan and carry out an investigation to determine if a chemical change occurred based on observable evidence (color, gas, temperature change, odor, new substance produced)
