UNIT A Let’s Get Started Components of a Bicycle Race BMX racing is a highly organized sport involving people, bicycles, safety equipment, racetracks, rules, and regulations. In this activity, you will distinguish between the components of BMX bicycles and the components of an organized race. 1. Get a large piece of paper. Write “BMX” in a circle in the centre of the page. 2. Fold the paper in half vertically. At the top of the left-hand side, write the title “Bicycle.” At the top of the right-hand side, write the title “Race” (Figure 1). This is the beginning of a mind map. 3. In groups of three or four, brainstorm all the parts you can think of that make up a BMX bicycle. Record each part in a separate bubble. 4. On the right-hand side of your mind map the page, extend to include what goes into organizing a bike race. 5. When your teacher asks you, leave your paper at your desk and do a gallery walk to see what others have written. Bring your notebook and a pen with you to jot down new ideas. 6. After you return to your desk, add to your diagram any new ideas you obtained from your classmates. Write these ideas in another colour. 7. Recall what you have learned about systems in previous grades and think back to how a system was described in the Unit Preview. As a class, complete a KWL chart (Figure 2). You will leave the “What we LEARNED about systems” column blank for now. Bicycle Race What we KNOW What we WANT to What we LEARNED about systems learn about systems about systems Figure 1 BMX Fold down centre of paper Figure 2 8. Answer the following in your own words. (a) Pick a bicycle part from one of your mind map bubbles and describe the types of forces that act on that part of the bicycle. (b) Look at the photos in the Downhill Daredevils story. Describe the protective equipment that the cyclists are wearing. Use the idea of forces to explain how the equipment protects the cyclist. 6 Unit A • Systems in Action NEL
Unit Task Preview Helping Hands BMX bikes are designed to meet the needs of their riders. Everyday systems are also designed to meet the specific needs of their users. As you progress through the unit, you will discover how important it is to consider the needs of others when designing systems. You will develop the skill of “systems thinking” by examining the interrelationships among the components of a system, and between systems, societies, and environments. Enable Industries Inc., is holding a contest called “Helping Hands.” The contest involves designing a system to meet a specific need. You will design and build one of the following devices. 1. A Better Gripper Opening jars can be a daily challenge for people with joint pain, reduced hand strength, or simply small hands. You will design and build a system that helps a person safely hold a container and remove its lid. 2. An Extension Grabber Some places are hard to reach for individuals with reduced mobility. You will design and build a system that enables people to reach into the far corner of a closet or under a bed from a sitting position to pick up objects. 3. A Cup Lifter Some people are not able to raise a cup to drink from it. You will design and build a system to raise a cup of water so that someone can drink from it without having to bend over or lift the cup. Unit Task By the end of the Systems in Action unit, you will be able to demonstrate your learning by completing this Unit Task. As you work through the unit, continue to think about how you might meet one of the above challenges. Read the detailed description of the Unit Task on page 80, and look for the Unit Task icon at the end of selected sections for hints related to the task. Assessment You will be assessed on how well you • plan and design your device • build, test, and improve your prototype • explain your device in a User’s Guide, and communicate your project to the judging committee NEL 7
