Question: Writing Assignment: Cooking and Eating

A pressure cooker is a special type of cooking pot in which the pressure inside the pot is increased. Pressure cookers cook food faster than traditional pots and pans. Suppose you place some green beans in a pressure cooker, cover them with water and close the pressure cooker so that the pressure inside the pot increases. You cook the beans and observe that they cooked much faster than they would have in an ordinary pot.

You sit down for dinner and eat your green beans. During the process of eating, your food goes through both physical and chemical change

Now consider the following question based on the concepts you have learned in this section.

1. Why would food cook faster in a pressure cooker?

2. What is one example of a physical change that food goes through as you eat it?

3. What is one example of a chemical change that food goes through as you eat or digest it?

Create a written report OR a recorded speech OR slide presentation to answer the questions above.

If you need to, you can do some web research with key words such as "how a pressure cooker works" or "digestion and chemical changes," etc.
