James Kirk Engineering Lesson Plan Types of Bicycles 1 Grade level: 6-8 Overview The students are learning about the origin of bicycles, how they work, how they have changed over the years and the many different types that exist. Objectives The students will learn: ● To be able to identify the different types of bicycles ● To be able to identify the different components of the bicycles that makes each one different. ● To be able to compare the different types of bicycles Standards ● MS. 4 Describe technology as it is applied in the context of communication, construction, design, manufacturing, transportation, and related technologies. ● MS. 16 Select the appropriate devices and systems to meet personal and societal needs. ● MS. 19 Determine the impact of technological actions on individuals, society, and the environment. Materials The instructor will need: ● Any type of multiple speed bicycle, Microsoft PowerPoint and a projector or overhead slides and an overhead projector. Procedure 1. The students should already be able to identify a bicycle. a. The students should be able to 1 This is my own lesson plan 1 James Kirk Engineering Lesson Plan identify the purpose of a bicycle. b. The students should be able to identify the basic components of a bicycle. 2. Bring out the multispeed bike. If the bike is a road bike, jump to the road bike portion of the presentation. If the bike is a mountain bike, jump to the mountain bike portion of the presentation. 3. With Microsoft PowerPoint or the over head slides, show a list of all the bikes and the example picture that will be included in the presentation (including the multispeed bike that was covered) a. Road Bike b. Mountain Bike c. Motocross Bike (BMX) d. Beach Cruiser/ Pathway Bike 4. Go over the specific components of the Mountain Bike. a. Explain the purpose of the bicycle and what it was made to do. b. Using a projected picture, point out the specific components of the bike and explain why they are there. i. Ridged light weight frame ii. Wide spread handle bars iii. Front suspension iv. Disk brakes v. Thick knobby tires vi. Multiple gears (set low) vii. Raised seat height vii. Rear suspension (if shown) 2 James Kirk Engineering Lesson Plan 5. Go over the specific components of the Road Bike. a. Explain the purpose of the bicycle and what it was made to do. b. Using a projected picture, point out the specific components of the bike and explain why they are there. i. Light weight frame ii. No suspension iii. V-brakes iv. Skinny tires v. Multiple gears (set high) vi. Raised seat height vii. Dropped handle bars 6. Go over the specific components of the Motocross Bike (BMX). a. Explain the purpose of the bicycle and what it was made to do. b. Using a projected picture, point out the specific components of the bike and explain why they are there. i. Undersized, heavy weight frame ii. No suspension 3 James Kirk Engineering Lesson Plan iii. Single rear V-brake iv. Normal set reinforced handle bars v. Small 20” wheels with thick tires vi. Single gear vii. Low seat height viii. Pegs 7. Go over the specific components of the Beach Cruiser/Pathway Bike. a. Explain the purpose of the bicycle and what it was made to do. b. Using a projected picture, point out the specific components of the bike and explain why they are there. i. Strong, heavy frame ii. No suspension iii. Coaster brake iv. Large thick tires v. High comfortable seat height vi. High set handle bars vii. Single gear (set low) viii. Wheel fenders ix. Thick padded seat Evaluation 1. Upon finishing the presentation the students will be split up into different groups depending on the size of the class 2. Each group will be given two pictures of two different bikes and 4 James Kirk Engineering Lesson Plan will be asked to identify the bikes and list the differences. 3. The students will have to do the same activity individually on an exam at the end of the chapter.
