2 ESL Activity I: Building Big Bones Teaching Point Science students will know the importance of lightweight bones and use models to show their understanding of how bones look and feel. 10 minute mini-lesson minute activity Bones aren t just dry, solid sticks! Bones are a living tissue, and need food and oxygen just like other organs and tissues! Vocabulary Words Blood Vessels- small tubes that carry blood throughout the body. Bone Marrow- the hollow space in the middle of the bone. Nutrients- natural elements that the body needs to grow and stay healthy. We get them mostly through food. Calcium- a kind of nutrient that the body uses to help make our bones strong. Every human being has a skeleton that is made of 206 bones. All of these bones work together to help you move the way you want to move. The bones also hold your body up and protect the organs inside your body! The outer layer of the bone is made of hard, compact bone tissue. hard bone spongy bone bone marrow At the center of some bones, there is bone marrow. In between the two layers of hard bone and marrow there is a layer of bone that is soft and light, almost like a sponge! This spongy bone allows you to move because it is lightweight like a sponge! Inside each bone you will also find blood vessels. The blood vessels help give your bones calcium and other important nutrients. Bones need these nutrients to stay strong and healthy.

3 Materials Needed: 2 cardboard tubes (1 for each partner) small rocks pieces of kitchen sponge Masking tape Scissors Ruler Permanent Marker Worksheet #5 and #6 Task You will be working with a partner to make bones out of cardboard tubes. In Part 1, you will fill the tubes with different materials, in Part 2, you will observe your partner s bone, and in Part 3, you will answer questions about the bones that you made. Ready! Set! Go! Instructions The person whose FIRST NAME comes FIRST alphabetically is Partner A. The person whose FIRST NAME comes LAST alphabetically is Partner B. Pair Up! Procedure Part 1 1. Gather all materials. 2. Partner A will fill their tube with rocks. 3. Partner B will fill their tube with sponge. B3 Partner A 1. Use a ruler to measure out a 1-inch piece of masking tape. 2. Write the word rocks on the tape. 3. Put your tape label on the side of your cardboard tube. 4. Cover one end of your tube with small pieces of tape so nothing can fall out of the tube. 5. Stand your tube up so the tape is on the bottom. 6. Fill your tube with small rocks, ALMOST to the top. Not too much! 7. Now, tape the end of the tube up so the rocks can t spill out! Partner B 1. Use a ruler to measure out a 1-inch piece of masking tape. 2. Write the word sponge on the tape. 3. Put your tape label on the side of your cardboard tube.

4 4. Cover one end of your tube with small pieces of tape so nothing can fall out of the tube. 5. Stand your tube up so the tape is on the bottom. 6. Fill your tube with sponge, ALMOST to the top. Not too much! 7. Now, tape the end of the tube up so the sponge can t spill out! What do you think are the differences between rocks and sponges? soft loud rough heavy inflexible quiet flexible Procedure Part 2 1. Take turns holding each others tubes. 2. Write your observations here: Example: How does the ROCKS tube feel? How does the SPONGE tube feel? Are they different? Are they the same? On your left are some useful terms you can use to write your observations! B4 noisy hard SPONGE ROCKS crunchy light 3. Write down your thoughts about bones:

5 WHAT WE KNOW About Bones WHAT WE WANT TO KNOW WHAT WE LEARNED _ B5 Procedure - Part 3 Answer the following questions: 1. Which materials made the bones lightweight and strong? 2. If bones were heavy like the bone filled with rocks, what kind of problems would humans have with movement?

6 3. Which material would be best for bones - the sponge or the rocks? Why? B6 4. How is the material you mentioned in Question #3 like spongy bone?
