A broken bone doesn't have to mean staying sedentary. After they conquer the initial pain of injury, kids with casts on their limbs usually bounce back quickly. The challenge for parents becomes twofold: Keeping them safe from re-injury, and also making sure they aren't spending their days glued to a screen. These xrays look great and come in various different sizes. Would buy again. Only thing is that the image is a bit fragile.

Summary

Students learn about the strength of bones and methods of helping to mend fractured bones. During a class demonstration, a chicken bone is broken by applying a load until it reaches a point of failure (fracture). Then, working as biomedical engineers, students teams design their own splint or cast to help repair a fractured bone, learning about the strength of materials used.
This engineering curriculum meets Next Generation Science Standards (NGSS).

Engineering Connection

Some engineers study bones, the skeletal system and the human body as they create methods and types of medical devices to help the body with many types of bone-related injuries, diseases and disorders. Modern splints and casts are products that protect, support or immobilize fractures during the healing process, as well as components to custom make them. Example devices include: finger splints, wrist/thumb supports, arthritis supports, cervical collars, knee/back supports, ankle/foot supports, shoulder supports/slings, casts, and compression and taping products, as well as x-ray and MRI equipment for diagnosis. Modern splints, slings and casts are durable, light-weight, comfortable, waterproof and/or removable.

Learning Objectives

After this activity, students should be able to:

  • Use a model to describe how a load might affect a bone.
  • Explain that biomedical engineers design medical devices to help in the healing of fractured bones.

Educational Standards

Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.

Introduction/Motivation

Do you know anyone who has broken a bone in his or her body? Have you? Bone fractures are common in our society, and some are more serious than others. Bone fractures can range from a very small crack in the bone to a complete break and separation of the bone. On average, people break a bone twice in their life. The occurrence is much higher among young children; bone fractures are among the most common types of injuries for children younger than 15. Children often are treated in the emergency room for a simple closed fracture, the most basic type of fracture.

Broken Bones Games For Kids

Today, we will be talking about the strength of bones and medical devices used to help repair a fractured bone. Let me read you a story:

Juan Skeleton is a healthy fourth-grader who loves to play soccer. One day he is outside at recess playing soccer with his friends when something happens to him.

As Juan slides to take the ball away from his friend Julia, his foot gets stuck in a hole in the ground and he hears something crack. This crack is in his lower right leg and it is very painful. Juan does not realize what just happened to him but he knows something is wrong. Bravely, he tries to stand up and walk off the field, but he cannot because the pain is too much to bear. Juan cries for help and his friends call the teacher who sees that Juan's leg is starting to swell.

Broken Bones The Game

The teacher, Mrs. Maria, carries Juan into the nurse's office. He explains what happened on the field, and both the teacher and the nurse realize that Juan just fractured the bone in his leg. Juan's parents are called and he goes to the hospital.

At the hospital, Dr. Arenas helps treat Juan's fractured leg. X-rays are taken to determine exactly where the fracture is located and how severe it is. After the tests and x-rays, Dr. Arenas tells Juan's parents that the fracture is not too severe. Juan has a simple closed fracture. Phew!! Good news for Juan (no surgery required to re-set the broken bones). The doctor tells his parents that Juan needs to have his leg wrapped in a cast to help heal the fractured bone.

The next day, Juan goes to school with a comfortable, light-weight and cool-looking cast on his leg. Since Juan cannot put any load on his leg or move it, he must use crutches to help him move. Juan is sad because for the next six weeks he cannot play soccer at recess, but he knows that the cast will protect his bone so it can heal and get better.

Many weeks after Juan hurt his leg, the cast is removed. After his leg regains its strength, he will be able to play soccer again! Yay for Juan!!

Did Juan's leg magically get fixed? What is the cast he had to wear? How did his bone fracture if he is a strong, healthy person? What is a fracture and is it different from a break? Why did Juan use crutches and was not able to apply any load/weight to his leg? You might be thinking about these questions and more!

In our activity today, we are going to see that even though Juan's bones are strong, too much load or force causes bones to fracture. A fracture is the same as a broken bone; the word 'fracture' is the term that doctors use. As for the cast, it is a medical device designed by biomedical engineers to help repair broken bones. Its purpose is to maintain the bone in a fixed position so that it does not move (get re-injured) and can heal. Today, we are going to measure the load that a bone can hold before it breaks and then you can design your own casts, just like biomedical engineers. Are you ready for some fun with bones and casts and splints?

Procedure

Background

By using chicken bones to simulate human bones (which are many times stronger) students see the amazing strength of bones. In the class demonstration, a point load is applied to a bone with a gradual increase in load (weight) until the bone can no longer support it and fails (fractures). In the hands-on student activity, student teams work as biomedical engineers to create and design casts or splints that immobilize body parts to help the body heal. They also explore the strength of materials as they test the strength of their casts/splints.

Before the Activity

Broken Bones Game Online

  • Gather materials, and make copies of the Bone Breaking Design Worksheet and Bone Breaking Group Testing Table, one each per team.
  • Thoroughly clean the chicken bones. Make a small fracture in each bone by taking a flathead screwdriver and carefully tapping it with a hammer until the bone cracks, being careful not to completely break the bone. Set aside one bone for the demonstration.
  • Place cast- and splint-making materials on a separate table to serve as the 'class store.'
  • (optional) If making plaster of Paris casts, cut newspaper into 2-inch (4-cm) strips. Make the paper-mâché mix in advance or have another adult make it during class.

Part 1: Observing Bones and Class Demonstration – Bone Breaking (Day 1)

Using two classroom tables or desks, follow the next steps to set-up the load testing area for the class demonstration.

  1. Move tables or desks to create an open 1.5-inch (~4-cm) span between them (see Figure 1).
  1. Using the S-hooks, connect a hook to each end of the link chain (see Figure 1).
  2. Hook an end of the chain, using the S-hook to the bucket handle (see Figure 2).
  1. Divide the class into teams of two or three students each.
  2. While at their desks, give each team a fractured chicken bone to observe. It should be similar to the one you are using for the demonstration, or pass around the bone that you are using for the demonstration to each group. Review pertinent concepts and functions of bones and the skeletal system.
  3. Have each group study their bones for characteristics, such as size, color, shape, strength, etc. Encourage students to examine the bone by sight, touch and smell. Tell them not to taste the bone or break it.
  4. Using Part 1: Gathering Information on the activity worksheet, have students draw the bone, write down any observations about it (size, color, strength, etc.), as well as a prediction of the total amount of load (weight) that the bone will be able to carry before failure (fracture).
  5. Once students have finished Part 1 of their worksheets, have all groups gather around the testing station.
  1. Using duct tape, take the demonstration bone and tape it across the open span of the tables/desks making sure the bone is fastened tightly to each side (see Figure 3).
  2. Use an S-hook to attach the loose end of the chain to the middle of the bone (see Figure 3). The chain and bucket should hang in the middle of the opening (see Figure 4). Make sure the bucket is suspended above the floor.
  1. For safety, keep bone pieces, marrow and other fragments from flying, by placing a clear plastic bin or container over the bone while you are adding weight to the bucket.
  2. In 5-lb (2.3-kg) increments, carefully add weight into the bucket, pausing for 5-10 seconds to allow the additional weight to settle. Do not drop weights into bucket; place them gently into the bucket. (Note: Most chicken bones are capable of holding 40-50 lbs [18-23 kg].).
  3. Continue to add weight until the bone cracks.
  4. Have students record on their worksheets the amount of weight that caused the demonstration bone to fail (fracture).

Part 2: Engineering Design and Cast-Making (Day 1)

  1. After the class demonstration, discuss with students their observations during the load testing: What did you notice as more weight was added? How strong is a chicken bone? Were you surprised to see the chicken bone carry that much weight? Do you think a human bone could withstand more or less weight?
  2. Review the healing process for fractured bones and the various biomedical devices (casts and splints) used to help heal bones, clarifying the differences between each.
  3. Have student teams return to their desks and complete worksheet Part 2, Analyzing the Information.
  4. Once students have finished Part 2, review the engineering design process with them and explain that they will be acting as biomedical engineers, designing their own type of cast or splint as a team. Explain to students that when engineers design a new or improved product, they work in groups and follow the steps of the engineering design process: 1) understand the problem or need, 2) come up with creative ideas, 3) select the most promising idea, 4) communicate and make a plan to describe the idea, 5) create a prototype or model of the design, and 6) evaluate what you have made, thinking of possible improvements.
  5. Introduce the design concepts and constraints for the activity. Either provide students with already-specified constraints that serve to limit and guide the design challenge, or brainstorm with the class to come up with additional constraints/design goals. Consider the following (or some combination) as suggestions for design goals/constraints: strength of the cast or splint, weight of the cast or splint, cost to make the cast or splint, most realistic cast or splint for usability.
  6. (optional step; follow if using cost as a design constraint) Reveal to students the types of 'store' materials available for the construction of casts and splints, and the 'cost' of each material (for purposes of this activity). Explain that one of their design constraints is cost; they may spend up to a certain amount of money (such as $200 in play money), but no more, to make their device. Hand out the play money to each team.
  7. Have students pick a specific type of cast (splint or plaster cast) to design. Give them 5-10 minutes to complete their design on their worksheets, including Part 3.
  8. Once students have completed their design and obtained teacher approval, direct one team at a time to obtain (or use their play money to buy) from the 'store' (teacher) the necessary materials for their medical device.
  9. After teams have supplies, have them create their model casts, building around their broken chicken bones.
  10. For teams that want to make a plaster cast, follow the paper-mâché-making steps (next section). Note: Making a plaster cast requires an extra 15-20 minutes plus overnight drying time, so allow enough time for this option.
  11. Once all groups have completed their splint or cast, have students pick up and clean their work areas.

Bike Jumping Games

'Plaster'-Making (Paper-Mâché) Steps (requires overnight drying time)

  1. Mix three parts warm water with one part flour and one part white glue. Stir until a smooth, creamy mixture is obtained.
  2. Cut newspaper into 2-inch (5-cm) strips.
  3. Dip each strip into the mixture and squeegee any excess material with fingers.
  4. Wrap the wet paper strips around the bone or bone covered with gauze, to make the cast. Help students, as necessary.
  5. Continue to dip and wrap the strips until the cast is finished. Let the groups decide how thick or thin they want their casts.
  6. Once all groups have completed their casts, have students pick up and clean their work areas.

Part 3: Cast Load Testing (Day 2)

  1. Recap with students their activity from the previous day(s). Briefly review the strength of bones, the types of bone disorders (such as fractures, osteoporosis, etc.), the methods and types of medical devices used to assist in these conditions, and the activity itself thus far (design goals, materials, etc.)
  2. Give teams time to make any final adjustments or alterations to their designs, or finish their casts/splints if they have not already done so.
  3. Once all groups have completed their casts/splints, gather around the testing station.
  4. Have teams number off to decide the order to test their casts. Or, provide a pre-selected list for the order.
  5. Guide each team to test the strength of their casts and how well they protect the fractured bones. For each team's cast/splint, use the testing station with bucket and weights, and repeat steps 9 through 14 from the bone-breaking demonstration.
  6. To keep all students engaged during the load testing, have students fill out the testing table to track the weight that each group's design was able to hold.
  7. Conclude by engaging students in the post-activity described in the Assessment section. Ask them to think about the materials in the different cast/splints, what worked and what did not, and what they might do to improve their designs.

Assessment

Pre-Activity Assessment

Exploratory Discussion: As a class, discuss the following topics:

  • What is a bone fracture? (Answer: A medical condition in which a bone is cracked or broken.)
  • Review the human skeletal system and the importance of bone strength.
  • Have you ever had a broken bone? If so, what was done to help heal the bone?

True/False Trivia: As a discussion extension, ask the following true/false questions and have students respond with thumbs up for true or thumbs down for false. Tally the votes on the board. Then, ask the same questions at the end of the activity and compare results.

  • True/False: Engineers create devices that help heal broken bones. (Answer: True)
  • True/False: Engineers do not need to know about the strength of bones in designing devices to help heal broken bones. (Answer: False. Engineers must study the strength of bones to determine what types of materials might help protect and support the bones.)
  • True/False: Engineers improve our lives by inventing things that can help repair our bodies. (Answer: True. Biomedical engineers study the body and are interested in designing devices to help make our lives better.)

Activity Embedded Assessment

Worksheet: Have students record observations, record results, design their casts and answer questions on their worksheets. Review their worksheets to gauge their understanding of the subject matter.

Engineering Design: Before and during the design and construction portion of the activity, remind students of the engineering design process steps: Define the problem (Ask), brainstorm ideas (Imagine), design (Plan), build and test (Create), and re-design (Improve).

Post-Activity Assessment

Graphing the Results: Using the data from the Group Testing Table, graph the maximum weight held from each team and the type of device used. Based from the graph, discuss which form of medical device proved stronger. Additionally, have students calculate the average weight held by both the cast and splint.

Closing Discussion: As a class, review the activity results and use the following questions to lead a concluding discussion:

Break My Bones Game

  • What happened to the chicken bone as more weight was added to the bucket?
  • Which casts/splints worked best? Why? What were they made of? Which materials worked best? What construction techniques worked best?
  • Based on the testing results from your and other groups, what could you do to improve your design?
  • Do you think human bones would be able to support more or less weight? Why? Would you make any changes to your cast/splint for a human bone? How?
  • What is a bone fracture? What types of medical devices are used to heal or repair a bone fracture? Would you change your design for fractures on an arm compared to a leg?
  • What is biomedical engineering? How are biomedical engineers and the human body related?

Safety Issues

  • Remind students not to taste, eat or bite the bone.
  • Remind students to be careful with scissors.
  • Keep students a safe distance from the testing station when conducting the demonstration or load-testing the casts/splints.
  • During load testing, have one person hold a clear bin over the bone and cast/splint, in case any pieces fly off.

Cartoon Network

Troubleshooting Tips

Make sure the load testing station works well. As necessary, make adjustments so the bone does not slip when weight is added to the bucket, the bone is covered with a clear bin to catch any scattering fragments, the spacing between the tables is not too wide or too narrow, etc.

Do not impose more than one or two specific design constraints in addition to the cost.

Making a plaster cast takes more time than the other options (+15-20 minutes plus overnight drying time), so allow enough time for this option. It also helps to have an adult assist students who choose to make a paper-mâché cast.

Cooked bones are probably easier to work with (and less messy!) than raw bones, but either can be used.

Activity Extensions

What happens if your bone injury is not a 'simple closed fracture'? An 'open, multi-fragmentary fracture' usually breaks the skin, exposing the bone to contamination, and involves the bone splitting into multiple pieces, which usually requires surgical repair to restore the bones to their natural positions. Have students research the engineering devices and techniques designed to treat these more complicated fractures. Devices might include surgical nails, screws, plates, pins and wires to hold the fractured bone together. Materials might include titanium, cobalt-chromium alloy, stainless steel and/or plastics.

Activity Scaling

  • For lower grades, remove some of the design requirements for the cast building and limit it to one achievable goal, such as cost, cast strength, or a waterproof cast, etc.
  • For lower grades, instead of having students 'buy' the materials for cast building, give each team a certain and limited amount of materials with which to work.
  • For lower grades, the design and construction of the casts may take a while to complete. To reduce the overall required time, eliminate the worksheet or eliminate the paper-mâché as a cast-building option.
  • For higher grades, add two or three additional design constraints and/or goals in addition to cost and strength.

Additional Multimedia Support

For ideas of the types of modern casts, braces, slings and splints, search for orthopedics, splinting and casting products in various online medical product catalogs, such as http://www.allegromedical.com or http://www.sammonspreston.com.
