Assignment 1 - Skeletal System WebLesson
Get ready to learn about your skeletal system! Your body has lots of bones! Bones help give your body shape.
All your bones together are called your skeleton. When we talk about the way your bones work together it is
called your skeletal system. Without your skeleton, you could not stand or even move. Think about what your
life would be like if you didn't have a skeleton, or if your bones didn't work together in a system.

Assignment 2 - Muscular System WebLesson
Muscles are attached to your bones to help them move. Without muscles you couldn't move at all! Muscles
also give us strength. Muscles are constantly doing simple things like helping you blink or breath. They also do
harder chores like help you run, jump, and play. So how do they work?

to load, so be patient. It is worth the wait! Then look at Muscular Introduction , and Your Gross & Cool Body:
Muscular System and answer these questions:

Assignment 3 - Respiratory System WebLesson
What's a respiratory system? Breathing and the way your body uses oxygen is
called respiration. We must breath to live. The organs used to help you breathe
and use oxygen make up the Respiratory System.

System Worksheet or download it and label that instead of drawing.)
2. Compare a cough and a sneeze. What are the similarities and differences?
Look at The Respiratory System
3. What is the Respiratory System ? How does it work? Share at least two
interesting facts about the Respiratory System.
Now go to The Human Respiratory System. (Site not available, I have used a
wonderful resource The Internet Archive's Wayback Machine to allow you to view
an archived copy) Read about your Respiratory System.
4. Describe how the air passes through the respiratory system, the four major
areas it travels through, and what happens in each place.

Assignment 4 - Digestive System WebLesson
The food you swallow goes on a long journey through your body. The digestion process begins as you take
your first bite of food and ends as your body disposes of the unusable parts. The digestive system mixes,
mashes, and breaks down foods into nutrients that your body can use. What is not needed leaves your body.
