Scientific Literacy: Newton’s First Law Comprehension SheetStudents define a force (as a push/pull) and write 5 things that forces causes things to do. Science Court episode: Forces and balanced and unbalanced forcesNewton’s second law: Acceleration of an object depends on the force and mass. The greater the force exerted on an object, the more it will accelerate. OR Acceleration (how fast an object speeds up)?depends on the force and mass.?The more force, the more it will speed up.?Scientific Literacy: Newton’s Second Law Comprehension SheetActivity – Students identify examples of forces on the Everyday Forces worksheetActivity – students complete balanced and Unbalanced Forces WorksheetForces and balanced and unbalanced forcesNewton’s third Law: For every action, there is a reaction that is equal in magnitude and opposite in direction. Scientific Literacy: Newton’s Third Law Comprehension SheetStudents predict the movement of objects with forces acting on themby using arrows to represent the direction the force is moving in.Newton’s First Law Comprehension SheetEveryday Forces worksheetNewton’s Second Law Comprehension SheetBalanced and Unbalanced Forces WorksheetNewton’s Third Law Comprehension SheetForce diagrams worksheet. Education Perfect Modules (new one every 2 weeks)3Inertia (ACSSU117) investigating common situations where forces are balanced, such as stationary objects, and unbalanced, such as falling objectsIntroduction: Watch the Car Crash Dummy Video and complete the inertia and your vehicle worksheet.As a group identify the forces working in the example.What safety features are there in cars that reduce the forces in the crash? How do they reduce the forces?Practical Activity“Newton and Seatbelts” Car crash dummies. Inertia and your vehicle worksheet Practical Activity“Newton and Seatbelts” p.16 (Part of Task 5)Task 4: Forces and motion experiment booklet.4/5Friction(ACSSU117) investigating common situations where forces are balanced, such as stationary objects, and unbalanced, such as falling objectsFriction as a forceRevise Newton’s Second Law of Motion. Acceleration = force x massWhat factors affect friction – eg. More mass, the less it will accelerate, and the more force is needed to move it.What is friction and what causes it?Friction is resistance that one surface or object encounters when moving over anotherFriction slows down moving objectsReducing friction Practical Activity“Investigating Friction” Part 1: complete an activity where students investigate whether the mass of an object effects the amount of force needed to move it.Part 2: Students choose one mass and change the surface to investigate which surface reduces friction the best, and therefore less force is needed to move an object.As part of the activity students will need to come up with other ways where Friction can be reduced.Practical Activity“Investigating Friction” p.16 (Part of Task 5)Education Perfect Modules (new one every 2 weeks)6-8Exam Revision and Exam(ACSSU117) investigating common situations where forces are balanced, such as stationary objects, and unbalanced, such as falling objectsRevision activitiesKahoot quizzesUsing mini whiteboards for in class quizzesEducation PerfectRevision booklet.Practical exam – set of stations set up. Students will complete over 1 period. Task 5: Practical Exam and Written Exam.Education Perfect online exam – NAPLAN style questions with a focus on literacy.9-10Simple Machines – levers – only if extension work is required.(ACSSU117) investigating a simple machine such as leverWhat is a lever?A simple machine is a device that makes work easier. A lever is a simple machine that has an arm that “pivots” against a fulcrum Student Activity: Students draw 3 types of levers Student Activity: Students conduct an experiment that investigates each type of Lever.
