1 Activity #12 What s happening inside? Challenge Question: Prediction: (Wait for directions) Evidence: (Draw, color and label how your Clay model looked when it was complete) Act #12 pg 1 of 3

2 Analysis Questions 1. The liver is the largest internal organ of the human body. (Was the liver the largest organ in your model? Do you think that the other organs you modeled were accurate in size? Why or why not?) 2. Was the model that you created in Part Two a good model of the human body? Why or why not? 3. Complete the table below. Systems include: Circulatory, Digestive, Excretory, Muscular, Nervous, Reproductive, Respiratory, Skeletal Function 1. Removes waste in the form of urine 2. Releases carbon dioxide into the air 3. Stores and breaks down food Organs and Structures System 4. Absorb oxygen from the air 5. Moves food into the body 6. Protects the spinal cord and supports the head and back 7. Holds solid waste before it is expelled from the body 8. Breaks down and neutralizes poisons 9. Helps the body move 10. Signals the body to react to changes in the environment like danger and the smell of food 11. Pumps blood around the body 12. Holds urine before it is expelled from the body 13. Protects the lungs and supports breathing 14. Absorbs water and salts from food 15. Carries messages from the sense to the brain. Act #12 pg 2 of 3

3 Organ Systems: Summarize the function of each organ system. Organ system Function Organ System Function Circulatory Nervous Digestive Reproductive Excretory Respiratory Muscular Skeletal Summary: In the beginning of Activity # I thought the answer to the challenge question was.. but now I think (or still think) My evidence for this is Act #12 pg 3 of 3

4 Disarticulated Skeleton In this activity, you will reassemble the disassembled bones of Mr. Bones. Once he is reassembled, you discover the four general groups of bones by coloring and labeling him. Part I: Disarticulated Mr. Bones 1. Obtain a disarticulated skeleton sheet, a pair of scissors, a glue stick, and a piece of colored paper. 2. Cut out the pieces and try to reassemble Mr. Bones Apart on your piece of paper. 3. Before you glue down your pieces, check your arrangement with Ms. Kim for approval. Part II: Labeling Mr. Bones 1. Now that Mr. Bones is reassembled, neatly label the following bones: Humurus Ribs Fibula Ulna Sternum Metacarpals Radius Pelvis Metatarsals Femur Patella Scapula Tibia Carpals Tarsals Phalanges Vertebrae/Spinal Bones Part III: Coloring Mr. Bones according to Bone Classification 1. Using the information below, you will now color code Mr. Bones into four groups: Long Bones, Flat Bones, Short Bones, and Irregular Bones. 2. Long Bones = Blue, Flat Bones = Red, Short Bones = Green, Irregular Bones = Yellow 3. Make a small color-code key on the top right corner of your paper. Long bones form the levers of our arms (humerus, ulna, radius) and legs (femur, tibia, fibula). Other long bones are in the hands and the feet (metacarpals and metatarsals). They are strong shafts made of compact bone tissue. They have large ends consisting of spongy tissue covered with compact tissue. They are slightly curved enabling them to absorb shock. Flat bones provide broad surfaces to protect other structures and for anchoring muscles. Examples include skull, some facial bones, shoulder bones (scapula), ribs, breastbone (sternum), and hips (pelvis). Flat bones are broad flat plates of spongy tissue sandwiched between two layers of compact tissue. Short bones are strong, irregular cubes, made of spongy bone covered with compact tissue. Short bones include the kneecap (patella), wrist (carpals), ankle (tarsals), and fingers and toes (phalanges). Irregular bones are shaped differently enough that they cannot be grouped with the other three types of bones. The proportion of spongy to compact tissue varies from bone to bone. Vertebrae (spinal bones) and some facial bones are in the category. Part IV: Mr. Bones wants to know On the back of your paper, answer the following questions in complete sentences. 1. What are five important functions of the skeleton? 2. Draw a bone and label the following: outer membrane, compact bone, spongy bone, and compact bone. Briefly describe each structure next to the labels. (Hint: Refer to textbook pg ) 3. What is cartilage? What is its function? 4. Compare immovable and movable joints. Provide an example of each.
