7.1: Forces & Motion 3 Dimensions & Progressions

Unit 1

CSD Resources Phenomena: Change in Motion

Objective

Overview

Materials

● Students watch one or two of the videos and make observations on the change in motion.

● “Science of the Winter Olympics--Ski Jumping” ● “ESPN Sports Science: The anatomy of a Top Fuel Dragster” ● Optional video for more drag racing fun: “Physics Drag Racing” ● Myth Busters Table Cloth Yank

● I can make observations about change in motion.

Activity: Balanced & Unbalanced Forces

Objective

Overview

Materials

● I can describe how

● Students participate in 2 different experiments showing balanced and unbalanced forces.

● Balanced vs. Unbalanced Forces Lab ● Cups ● Pennies ● Rulers ● Ping Pong Balls

balanced and unbalanced forces affect objects.

Activity: Newton’s Laws Webquest

Objective

Overview

Materials

● I can 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.

● Simulations provide experiences that are

● Computer/iPad Lab ● Newton’s Law Simulation Investigation ● Newton’s Law Webquest

diffcult to replicate in the lab and help students explore how forces change the motion of objects

Activity: Gizmo - Free Fall

Objective

Overview

Materials

● Observe that all objects fall at the same rate in a vacuum.

● Investigate the motion of an object as it falls to the ground. A variety of objects can be
