Additional Learning Objectives 1. Know what mechanical engineers make/ what their job entails. 2. Know what an engine is. Required Background Knowledge 1. Introduction to engineering – Sparky’s Engineer 1.A.I Essential Questions 1. What is a mechanical engineer? 2. What do mechanical engineers do/make? 3. What is an engine? Introduction / Motivation Ask students if they can remember what a mechanical engineer is. See if any of the students can give examples of what mechanical engineers do. Procedure Session I: What do mechanical engineers do? – 20 minutes Instructor preparation: 1. Print out the pictures of the car, train, and motorcycle found in the attachment section. 2. Print out one “What is a Mechanical Engineer?” handout for each student. The instructor will: 1. Show the attached pictures of a car, a train, and a motorcycle. For each picture have the students identify what the object is and what it is used for. -2- Partnerships Implementing Engineering Education Worcester Polytechnic Institute – Worcester Public Schools Supported by: National Science Foundation Explain that a mechanical engineer designed all of these objects. Mechanical engineers also help design boats, and robots. 2. Distribute the “What is a Mechanical Engineer?” handout to the students and instruct them to complete it. 3. Review the worksheet with the students. Session II: Making an engine – 25 minutes Instructor preparation: 1. Photocopy attached take home letter for parents along with the “Wheels” and “Template B: Chassis” templates following the letter. Send home in advance so that students can collect materials. 2. Photocopy Template “A” onto printer paper for each student. 3. Ensure that all students have 4 cutout wheels, 2 unsharpened pencils, a rubber band, a 5”x7” piece of thin cardboard, and corrugated cardboard cut out as shown in Template B. The instructor will: 1. Distribute the pencils, rubber band, cardboard wheels, thin cardboard, Template “A” photocopy, and precut corrugated cardboard. 2. Have students cut around the large dotted black line of Template “A.” This will help make it easier to glue onto the thinner cardboard. -3- Partnerships Implementing Engineering Education Worcester Polytechnic Institute – Worcester Public Schools Supported by: National Science Foundation 3. Have the students glue Template “A” to the thinner cardboard using a minimal amount of glue. The students can choose to have the template on the top or bottom, depending on if they want the box to show. 4. Instruct the students to cut out the shape of the car once the glue is dry along the solid line. 5. Use a hole punch to punch out the 4 rectangles on the sides of the car. This is where the pencils will be held. It is important that when the pencils are inserted through these holes the pencils are lose and can rotate freely. If not, the car will not move when put together. Pencils go through these holes to act as axels for the car -4- Partnerships Implementing Engineering Education Worcester Polytechnic Institute – Worcester Public Schools Supported by: National Science Foundation 6. Punch holes in the center of the wheels. A sharpened pencil can be used to make the hole as well. 7. Bend the 4 sides of the car on the dashed lines. Staple the corrugated cardboard on top of the thinner cardboard. This is done to make the car sturdier and not bend. . 8. Insert the pencils through the holes and attach the wheels to the ends of the pencils. Use tape to hold the wheels upright and in place if necessary. -5- Partnerships Implementing Engineering Education Worcester Polytechnic Institute – Worcester Public Schools Supported by: National Science Foundation 9. Cut the rubber band in half and staple it to the front of the car. Use tape to secure the rubber band to the rear pencil. Wind the pencil up, put the car on the floor and let it go! This works better on the carpet instead of hard floors or desks due to friction. Session III: Testing the engine – 30 minutes The instructor will: 1. Let the students have a contest to see whose car will go the farthest. -6- Partnerships Implementing Engineering Education Worcester Polytechnic Institute – Worcester Public Schools Supported by: National Science Foundation Materials List Materials per class Pictures of car, train, and motorcycle Tape (scotch or masking) Stapler Amount One Office supply store Office supply store Materials per student “What is a Mechanical Engineer” worksheet Template “A” Thin cardboard for Template “A” Corrugated cardboard for Template “B” Rubber band (the longer and more pliable the better) Unsharpened pencil Location Attachment section Amount Location 1 per student Attachment section 1 per student 1 per student Attachment section Around the house (cereal box) 1 per student Around the house (corrugated cardboard box) 1 per student Office supply store 2 per student Office supply store Vocabulary with Definitions 1. Engine – a machine that makes objects move. 2. Mechanical Engineer – a person who helps design cars, engines in trains, cars, boats, and airplanes. They also design things like toys, machine parts, and appliances. Assessment / Evaluation of Students The instructor may assess the students in any/all of the following manners: 1. Check to see if the students have followed directions and assembled their engines properly. 2. Ask the students what mechanical engineers do. Lesson Extensions None Attachments 1. Car picture 2.

Students will be using the engineering design process to design, construct, and test a model car. We ask that you please have your child bring in 2 unsharpened pencils, a rubber band, and a 5”x7” rectangle from a cereal box or similar cardboard box. We also ask that you use the 2 attached templates to cut out cardboard pieces for your child to make their car. Please cut out 4 wheels and the shape provided in the template using corrugated (thicker) cardboard. If you could help your child gather these materials and then have your child bring them to school on ____________________________________it would be greatly appreciated. Thank you for your support!
