Sheila Porter Intel Ireland PowerPoint Presentation III Making Machines and Observing Functionality

Session 6: Making Machines Understanding the session:  Exploration of the mechanics of simple machines  Practical based lesson in which the student builds different types of “toys” using basic mechanics The session is broken down into 3 sections Section A: Design, Build, & Make It Go Section B: Gears, Cranks, Crankshafts and Belts Section C: Using Motors to Produce Motion

Activity 5A: Rolling Kit Goal: To allow students to become more familiar with the ideas behind basic mechanics, how energy can be stored, transferred and transformed. Outcome: Make a “Rolling toy which can travel metres as an introduction to mechanical engineering. Preparation: To do this you will need “One Rolling Kit” per student Materials required (“Rolling Kit”): 1 film canister with lid, with holes (8mm – 10mm Ø) drilled in both ends 2 Rubber bands (6.5cm) 2 small washers 1 piece of thick drinking straw Session 6, Activity A

Building the Rolling Toy Note: If film canisters are unavailable use empty coke cans See Design and Discovery Website - Resources Rolling Toy Video

Students  Are introduced to the concepts of mechanical engineering  explore the mechanics of simple machines and learn that most mechanical devices are really a set of simple machines working together  learn how machine action can be transferred or change direction by experimenting with gears, wheels and belts, and crankshafts Gears, Cranks, Crankshafts & Belts Crankshaft

Example of a Crankshaft Toy See Design and Discovery Website - Resources Crankshaft Toy Video

Materials Small milk carton 3 pieces of 16-gauge steel wire - 1 x 20cm long - 2 x 7cm long 1 straw Insulating tape for crank handle Needle nose pliers

The Session ends with the students building a Wacky Racer Can you build a Wacky Racer?
