Introduction
Our bodies are remarkable feats of interactions and complexity. We perform most actions without thinking about all the coordination and mechanics that go on in our body. Why do we need to eat and sleep? How much do we need to eat? How much energy do we use? What affects our energy levels? How quickly can our body convert the food we eat to energy? Starches, fats, and protein take time to be converted to energy. In this WebQuest you will develop an understanding of the concepts and topics related to the human body to aid you in understanding the body s energy needs and how various organ systems contribute to energy transformation in the human body for the Human Body: Energy Needs and Energy Transformation unit.

Purpose of Activity
The purpose of this activity is to introduce students to the key systems of the human body that relate to human energy needs as well as the key ideas and terms to help them with the 2 week unit on the human body.
Materials needed
Students will need access to the internet and a computer. This activity is best done in a computer lab so all students have access to a computer to work during class time.
Time required
It should take students no more than a full class period to complete this assignment (45 minutes).
Body Systems
Use the following link to answer the questions below. http://kidshealth.org/kid/htbw/htbw_main_page.html You should be on the page that says How The Body Works. Scroll with the microscope until you reach Stomach, Lungs, and Heart to answer the questions. Please answer in complete sentences with proper grammar if it is a short answer question.

Digestive System
1. The digestive system is made up of organs that work ________________ to break down food and turn them into ___________ to help your body work and grow.
2. T or F: The digestive system in the video includes all of the following: mouth, tongue, salivary glands, esophagus, liver, stomach, pancreas, small intestine, large intestine, rectum, gall bladder.
3. The digestive system process begins at the ________ and ends at the ______. This digestive tube is ________________________ in adults.
4. The blood brings ______ , __________ , ____________________, and __________ to the liver, which helps make them into __________________ the body needs to live and grow.
5. _______ from the liver and _______________________ from the pancreas help release nutrients from the food so they can be absorbed and __________________ around your body and bloodstream.
6. Where is feces formed?
7. Describe the process that occurs during digestion. Include the organs, their functions, and the location as food moves through the digestive system.

Respiratory System
1. What is the respiratory system made up of?
2. What is a question you have about the respiratory system? How will you answer it?
3. How does the respiratory system work? (What gases are exchanged and in what direction?)
4. T or F: The diaphragm relaxes when you breathe in and contracts when you breathe out to push carbon dioxide out of your lungs. 5. What s surprising to you about bronchioles?
6. When you exercise you need to ____________________ to bring in more oxygen and get rid of more carbon dioxide.

Circulatory System
1. The heart is roughly the size of (circle one): your palm, your fist, or your foot.
2. Blood carries ______________ and ______________ the body needs and carries away ___________________________ and ____________________________. This is called circulation.
3. What are the 4 chambers of the heart?
4. T or F: The chambers of the heart are synchronized.
5. T or F: The atria receive incoming blood, which moves to the ventricles to be pumped out.
6. The _________________ of the heart pumps oxygen poor blood from the body to the lungs while the _________________ brings oxygen rich blood from the lungs to the body.
7. T or F: There are 4 valves that move blood in the right direction.
8. T or F: The sound that your heart makes when it beats is the valves opening and closing.
9. _______________________________ is the measurement of the force of blood as it flows through arteries of cardiovascular system.
10. Is this correct for blood pressure: diastolic/systolic? Do you know your blood pressure? How can you find out?

Conclusion
Wrapping it all up
Please write a half page summary of what you ve learned through the WebQuest and hand it in no later than a week after completing the WebQuest. You can also choose to take the quizzes in each section on the digestive, respiratory, and circulatory system and print them out to hand it. You must have earned at least an 80% on the quizzes.
Further exploration
Now that you ve explored how various organ systems contribute to energy transformation in the body, try to think about how you can create a balanced lunch for yourself taking into consideration calories, energy input (energy from food) and output (energy used up), and energy transformation. The following websites may be of help to you: Energy Challenge http://www.abpischools.org.uk/page/modules/energychallenge/activity.cfm?age=Age%20Rang e%207-11&subject=Science Balanced Diet http://www.abpischools.org.uk/page/modules/balanceddiet/activity.cfm?coSiteNavigation_allT opic=1 Mitochondria http://www.biology4kids.com/files/cell_mito.html Cellular Respiration YouTube Video http://www.youtube.com/watch?v=wHM4X0I4iq0 Some guiding questions for cellular respiration: When Paul first starts exercising, what form of energy was converted to what? Once you hit the wall, is it possible to use more energy to keep going? If so, how?
