Push and Pull Simple MachinesAbout the PackTo the teacherTeacherTo the teacherThe pack is designed around the display and rolling stock in the Fitch Pavilion, which relatesto simple machines - Push and Pull. Worksheet is self-guided and is supported with aMuseum map and Answer sheet.About Push and Pull - Simple Machines at the MuseumDefinitions to know:Work - done when an applied force causes an object to move inthe direction of the forceEnergy - ability to cause change; can change the speed, direction, shape or temperature ofan objectLoad - the weight being lifted by the simple machineEffort - effort is the force placed on the simple machine to movethe loadWhat are simple machines? simple machines are tools that make work easier simple machines make work easier for us by allowing us to push or pull over increaseddistance they have few or no moving parts simple machines give us an advantage by changing the amount, speed, or direction offorcesTypes of simple machinesTwo groups:Inclined planes ramp wedge screw1

Levers lever wheel and axle pulleyIn the Museum you find many simple machines - wheels, axles, ramps, levers, pulleysYou can also find may complex machines made up of two or more simple machinesworking together. The railway uses many different types of machines to make workeasier for people.ScienceYear 3Curriculum content descriptionsElaborationsWith guidance, identify questions in familiar choosing questions to investigate fromcontexts that can be investigateda list of possibilitiesscientifically and make predictions based on jointly constructing questions that mayprior knowledge (ACSIS053)form the basis for investigation listing shared experiences as a wholeclass and identifying possibleinvestigations working in groups to discuss things thatmight happen during an investigationScienceYear 4Processing and analysing data andinformationCompare results with predictions,suggesting possible reasons for findings(ACSIS216)Elaborations discussing how well predictionsmatched results from an investigationand proposing reasons for findings comparing, in small groups, proposedreasons for findings and explainingtheir reasoningMathsYear 3Measurement and GeometryMeasure, order and compare objects usingfamiliar metric units of length, mass andcapacity (ACMMG061)Elaborations recognising the importance of usingcommon units of measurement recognising and using centimetresand metres, grams and kilograms, andmillilitres and litresMathsYear 4Curriculum content descriptionsCompare angles and classify them as equalto, greater than, or less than, a right angle(ACMMG089)Elaborations creating angles and comparing them toa right angle using digital technologies2

ScienceYear 7Science UnderstandingChange to an object’s motion is causedby unbalanced forces, including Earth’sgravitational attraction, acting on the object(ACSSU117) investigating a simple machine such aslever or pulley systemElaborations investigating the effects of applying different forces to familiar objects investigating common situations whereforces are balanced, such as stationaryobjects, and unbalanced, such as fallingobjects investigating a simple machine such asa lever or pulley system exploring how gravity affects objects onthe surface of EarthDesign and TechnologiedFoundation to Year 2Knowledge and UnderstandingExplore the characteristics and properties ofmaterials and components that are used toproduce designed solutions (ACTDEK004)Elaborations developing new meanings for objectsand action during play, for exampleexploring how household packagingcan be used to represent other objects exploring systems used in theclassroom or community for creativelydealing with problems and needs,for example storage systems forequipment, traffic system flow for dropand go zones, the use of hoists andramps to facilitate access exploring facilities in localenvironments for accessibility andenvironmental impact, for examplelocation of bike tracks and sportingfields using digital maps to view localarea experimenting with techniques tocombine or alter materials to satisfy afunctionResource designThis pack has been designed in accordance with the SACSA framework. Material is mostsuitable for Year 3, Year 4, Year 5, Year 6, Year 7.For the StudentSuggested Support Material, comprising of sheets A to E, which will help you in yourpreparation. Bring your Worksheet - comprised of seven questions, when you visit theMuseum.3

Push and PullWorksheet1 Locomotives push and pull many different types of things.Explore the Fitch PavilionDraw a line to match the name of the wagon to the photoSAR Carriage 3Provision VanCaboose No 4367Wooden Tool and GoodsVan No 2514

2Find the Glenelg Line Signal, located near row 3.Find a lever, wheel and pulley. You can operatethis interactive exhibit.Pull the lever to move the signal. If the armis pointing straight out should the train stop or go?(Clue: read the instructions).Demonstrate/explain how this lever makes heavy work easier.5

3Go to the large platform - Break of Gauge Platformin the Fitch PavilionWhat simple machines can you find on the platform?.Is the machine a example of a lever or a pulley?.do you push or pull the machine?.also discuss ramps/platforms versus stairs luggage and goods height of ramps energy and force to move objects do you need less energy and force to move objects with a platform6

4Power/energyIntroductionTypes of power/energy have been used over timeto help move wagons, vans, carriages etcFind the MIC 4 (refer to your map and photo)Complete the sentence, by underlining thecorrect answer.The car was operated bysteam/motor/hand?Find the locomotive - Rx93Underline the type of power that moves this locomotiveelectricitypeople chemicaldieselsteam movementFind the fire truck in the photo. It is near the entrance of theFitch Pavilion. Sorry you cannot move this exhibit.Can you find a lever, axle or wheels? How is the truck moved?.Look at the display in The Long Journey - Women In Railways.Find the red Hard Yakka 3 wheel Pump TrikeComplete the sentence, by underlining thecorrect answer.The trike was operated bymotor/steam/hand?Is the trike moved by pushing or pulling?.Can you find a lever?7

5Wheel and AxleIntroduction the axle is a rod that goes through the wheel and lets the wheel turnExplore the museum. Discuss the size of locomotivewheels. Look for the axle.How was the Explosives Van moved?.6Go to the Model Railway and the display cases (refer to your map)List the toys and models that can be pushed and pulled.Discuss the objects in the Model Railway how are they moved/powered in real life.8
