Weekly Homework March 15-19

One option this week Food Flight Due: Friday

Problem: Imagine that you are a food traveling through the digestive system. How can you make a series of postcards to describe your trip?

Suggested Materials:

large note cards

colored pens or pencils

Devise a Plan
1. Study the materials and think em to describe a food's trip through the digestive system. You will need to create five postcards, one for each of five major areas of the system: the mouth, the esophagus, the stomach, the small intestine, and the large intestine

2. Choose a food. On one side of each postcard, use words to describe the journey from the food's point of view. On the other side of the postcard, draw a picture of something that the food might "see" or pass through during each part of the trip. For example, suppose the food you chose was an apple. Your postcard describing the mouth might have a picture of teeth on the front. The message on the back might begin, "Dear Mac-So far, I have had a miserable trip. I haven't even left the mouth yet, and already the teeth you see on the other side of this postcard have torn me apart, crushed me, and cut me into pieces."

3. Try to include as much information about the digestion system on your postcards as you can. Be sure to explain the function of each part or structure that you describe. Also, define any science words that you use, such as absorption
or enzyme.

Analyze and Conclude

After following the plan you devised, answer the following questions on a separate sheet of paper.

1. Identify two types of nutrients your food contains and explain why each of these nutrients is important to the body.

2. To which food group or groups of the Food Guide Pyramid does your food belong?

3. In which part of the digestive system are most of the nutrients of your food absorbed?

4. In which part of the digestive system does your food become a thick liquid?
