Elementary Science: Simple Machines2011-2012
Goal:Co-ordinate with teachers to create a common approach to teaching the Grade Five Science Unit “Simple Machines” that builds on the development of Scientific Literacy and the Goals of the BC Curriculum.
Scientific literacy is an evolving combination of the science-related attitudes, skills, and knowledge students need to:
develop inquiry, problem-solving, and decision making abilities as citizens become lifelong learners maintain a sense of wonder about the world around them

Learning Outcomes - Physical Science: Forces and Simple Machines
It is expected that students will: demonstrate how various forces can affect the movement of objects demonstrate mechanical advantage of simple machines, including lever, wedge, pulley,
ramp, screw, and wheel design a compound machine describe applications of simple and compound machines used in daily life in BC communities

Steps in the ProcessStew Savard ([email protected]) Page 1
Elementary Science: Simple Machines1. Create, on the SD71 eLibrary pages, set of accessible resources for
students, teachers and parents to support the development of “inquiry, problem-solving, and decision making abilities” central to Scientific Literacy.
2. Build an easily adaptable set of assessment tools, for this unit, which reflects both 21st Century Skills and the Essential Skills needed by students.
3. Identify a common kit that can be used by all teachers in SD71 and sustained by the Learning Resource Centre.
4. Identify teachers with Grade Five Science assignments and build a community of sharing teachers.
5. Identify teacher/teachers at a school and team teach initial unit (bridge between what they’ve been successfully teaching with new resources – physical and tactile). Build on experience so that the lessons, from successive iterations, can be shared with the Science community.
6. Identify multi-year crossover opportunities so that students who use equipment/tools in grade five can access similar equipment/tools in later grades so that experiences become integrated over time.
7. Invite Fred McGregor to share in what we are doing so that the strongest Green elements possible can be built into our practice.
8. Create a path knowledge path for parents to follow that provides them with an awareness of this part of the curriculum, the learning outcomes related to these Science topics and possible short-term and long-term resources and support for students with a passion for Science and Technology.
9. Create a simple set of Career links for student to follow so that they inform themselves about career and other life-long choices related to Science and Technology.

Elementary Science: Simple Machines
Process to date:
Introduction1. Intro to the Simple Machines kits and a description of the pieces. Suggest you then do a
inventory of the yellow and grey “hubs” at the top of the kit.
2. Intro to the Building booklets.
3. Sort students into pairs and set desk heights.
4. Unpack kit, find books for build 1a and 1b and set top tray on desks

Builds5. First build – project number 1 – “Lawn mower”
a. Critical Learning Elementsi. The Ikea moment – graphical/photographic literacyii. Transitional boundaries
b. I Stand to Learnc. Inventory – (left hand row – blue beams and blue flat pieces)

Elementary Science: Simple Machines
6. Second build #4 - “Hammer” (Must place the “join” properly)More complex. Lever. Wedge. Screw. Gear. Allows for gravity and friction conversation
Inventory – (mid-left row – mixed shapes and white beams)
7. Third build #2 - “Fishing pole” Simple build (String gets knotted)Pulley. GravityInventory – (middle – yellow-grey hubs, black-blue, red ‘torches’)
8. Fourth build #5 “Geared racer”Simple build. Five runs to conduct Engineering Experiment. Centre of Balance – offsets force of gravityWhat is forward – backward?Build it out – down ramp longest run
Inventory – (right-middle – light-dark grey, beige, ‘weird’ pieces)
9. Fifth build # 11 “Powered car” batteries (floor races – up the inclined plane)Power – Gearing – Types of wheels (allows for “fastest racer)Batteries in and out every class
Inventory – (right hand row - gears – mixed pieces)
10. Sixth build #13 “Walker” Hip movement (a levered activity) – undersea pollution rescueAll done on joined student desks.
Inventory – (right hand row – axles and bottom tray all pieces)
