Kitchen Gadgets Galore!Student HandoutIntroduction:Have you ever thought about mixing and baking a cake with your bare hands? What about flipping aflapjack or beating an egg? Luckily, we don’t have to do these things with our bare hands. We aresurrounded in the kitchen by numerous gadgets that make our lives much easier.Kitchen gadgets; such as can openers, vegetable peelers, and pizza cutters; are machines—devices thatmake doing work easier. These machines are made up of one or more simple machines, i.e. levers,pulleys, wheels and axles, inclined planes, screws, and wedges0.In this activity you will explore the simple machines that make up common kitchen gadgets. In PartOne, you will examine several common kitchen gadgets and identify the simple machines that make upeach gadget. In Part Two, you will use your knowledge of simple machines to design your own newkitchen gadget.Purpose:1. To identify the simple machines that make up common kitchen gadgets2. To design a new kitchen gadgetMaterials:Part One -15. Corkscrew16. Egg slicer17. Ziploc® container18. Spatula19. Pizza cutter20. Tongs21. Scissor tongs22. Nutcracker23. Nut pic24. Can opener25.

Brass paper fastenersProcedure:Part One –For each of the common kitchen gadgets listed above complete the corresponding worksheet.1. Examine the gadget.2. Describe the function of the gadget. For what task is the gadget designed?3. Identify the simple machines that make up the gadget.The Science Behind Our Food

4. Sketch the gadget to scale. Clearly label all simple machines that make up the gadget. Forlevers, include class and locations of fulcrum and input and output forces.Part Two -1. Your task is to design a new kitchen gadget. Think about a job in the kitchen that you wouldlike to make easier. You will design a new kitchen gadget that combines two or more simplemachines to accomplish this task. The following information regarding your new gadget shouldbe recorded on the worksheet provided.• Name of Gadget• Description of Gadget – Describe the gadget. Include the number and types of simplemachines that make up the gadget.• Function of Gadget – Describe the task for which the gadget was designed to accomplish.• Labeled Drawing of Gadget – Sketch the gadgetand clearly label the simple machines that make up the gadget. For levers, include classand locations of fulcrum and input and output forces.2. Using the provided cardstock and brass paper fasteners, construct a model of your new gadget.The model should be built to scale and should function as much as possible.The Science Behind Our Food
