Students will plan investigations to provide evidence that the change in an objects motion depends on the forces acting on the object and the mass of the object. Students will apply Newton’s third law (for every action there is an equal and opposite reaction) to design a solution to a problem involving the motion of two colliding objects. Student expected prerequisite knowledge Common student misconceptions PS2.A (3-5) The effect of unbalanced forces on an object results in a change of motion. Patterns of motion can be used to predict future motion. Some forces act through contact, some forces act even when the objects are not in contact. The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center. 2|Page Unit Completed by: Date: Science Grade 7 Unit 1 Bend 2 Unit Learning Outcomes Bend Title: Bend Description: Disciplinary Core Ideas: Standards: Grade 1 Unit Length Content Unit 7 Energy: Forces Affecting Motion (Bend 1 of 4) In this bend, students will explore Newton’s laws of motion. Students will plan investigations to provide evidence that the change in an objects motion depends on the forces acting on the object and the mass of the object. Students will apply Newton’s third law (for every action there is an equal and opposite reaction) to design a solution to a problem involving the motion of two colliding objects. PS2.A: Forces and Motion For any of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction. (Newton’s third law). The motion of an object is determined by the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. PS2-1 Apply Newton’s Third law to design a solution to a problem involving the motions of the two colliding objects.* PS2-2 Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. PS2-5 Conduct and investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact. 3|Page Unit Completed by: Date: Science Essential Questions: Grade 7 Unit 1 Bend 2 How can one describe the physical interactions between objects and within systems of objects? (These goals should be aligned to Standards.) Goals: (These should be aligned to the Goals above) Learning Targets & Skills Students will be able to apply Newton’s Third law to design a solution to a problem involving the motions of the two colliding objects I can… Students will understand that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. Students will understand that fields exist between objects exerting forces on each other even though the objects are not in contact.
