4. Today we are going to learn about one of the organ systems—the skeletal system. This system is all about the bones in our bodies. Bones have five different functions, or purposes. At first glance, the skeletal system might not seem as important as some of the other systems, but today you’ll learn why we can’t live without it.

5. Notes
Remember to be filling in your notes sheet as we go through the information together. After we write our notes, we will review using the PowerPoint.

6. What are the five functions of the skeletal system?

7. Functions of Bones Provide shape and support to the body
Protect internal organs
Enable motion
Make blood cells
Store minerals

8. Function #1: Shape & Support
Provide shape and support to the body

9. Bones determine an animal’s shape

10. Shape is determined by bones

11. Not just shape, but support

12. Function #2: Protect Internal Organs

13. Function #3: Help us to move
Enable motion by giving muscles a place to attach themselves

14. Function #4: Make Blood Cells

15. Function #5: Store Minerals
Got Milk?
Your body stores calcium and other minerals in your bones, so you can save them for later.
Eating/drinking calcium makes bones stronger, because more minerals are stored inside them.

16. Real-life examples Human femur (upper leg bone) Bigger Longer Wider
Looks stronger
Elephant Femur

17. Arms
Human arm
Whale arm

18. Bat Skeletal System

19. Triceritops

20. Bird Bones
Ostrich femur
Typical bird femur

21. Bone Facts Bone is five times stronger than mild steel.
Every three months our bone cells are completely replaced.
Almost a quarter of your bones are in your feet and ankles.
One out of 20 people have an extra rib.
A person's nose and ears continue to grow throughout his or her life.
Your thumb is the same size as your nose.

22. Glossary Time

23. Complete the Skeletal System worksheet on your own.

24. Tuesday Feb 5 or Wednesday Feb 6

25. Today’s Plan
Read about the skeletal system to reinforce what we learned last time and to learn even more about this organ system
Complete the Shape of Bones lab to better understand how the shape of bones impacts their strength
Complete an exit slip to make sure you understand the skeletal system

26. Skeletal System Article
Read about the skeletal system together and then answer the questions on the worksheet.

27. Shape of Bones Lab
Follow the directions to complete the lab.

28. Cylinder: A 3-D object that has
two flat circular ends
Rectangular Prism: a 3-D rectangular
object with 6 faces
Triangular Prism: a 3-D prism with
triangles for bases

29. Exit Slip Time!
Label your note card with your FIRST AND LAST NAME, DATE, and HOUR. Labeling this correctly is worth one point.
First and Last Name Date Hour 1. 2. 3. 4.

30. Exit Slip
Clear everything off of your table. Close lab books and put them on the floor.
NO TALKING, at all. If you have a question raise your hand SILENTLY and wait for the teacher.
When you’re done, flip your exit slip over and draw a picture of a skull.

31. Question 1
1. True or False: We would not be able to move without the skeletal system.

32. Question 2
2. True or False: Blood cells are made inside of bones, so without the skeletal system we would not have blood.

33. Question 3 3. Which is not a function of the skeletal system:
Protection
Movement
Storage
Strength
Support

34. Question 4
4. Write at least one sentence explaining why we need to skeletal system to stay alive.

35. Thursday Feb 7 or Friday Feb 8

38. Facts about the Muscular System

39. A single muscle cell of the sartorius muscle in the thigh can be more than 12 inches long.
The strongest muscle of the body is the masseter muscle used for chewing!

40. Your hand contains 20 different muscles.
If all your muscles could pull in one direction you could create a force of 25 tons!
Muscles account for approximately 40% of your body weight.

41. No matter how much you exercise you can not increase the number of muscle cells you have. By getting bigger, via strength training, you are simply increasing the size of each muscle cell.
The muscle that lets your eye blink is the fastest muscle in your body. It allows you to blink 5 times a second.

42. You have all the muscle fiber you will ever have at birth
You have all the muscle fiber you will ever have at birth. Once damaged they can't be replaced.
Arnold Schwarzenegger has as many muscle fibers as you - They're just thicker!
