8th Grade Science FOSS Unit: Electromagnetic Force
Inv 1 Test – Jan 15 What is Force
Investigation 1: What is Force
A force is a push or a pull.
The metric unit for force is the newton (N).
Friction is a force that acts to oppose a force acting to put a mass in motion.
The net force is the sum of the forces acting on a mass.
1.1 Push and Pull
Focus Q: What makes things move?
NB Sheets 1,2, & 3 (Pushes and Pulls A, B & C)
Students will demonstrate that a force is a push or a pull that will transfer energy to an object to cause it to move by:
Testing and measuring how much force is required to move objects
Describe force, interactions and newton’s, energy, kinetic energy and friction
Read/analyze Article: “The Force is with You”
Focus Q: How does friction affect the force needed to move an object?
NB Sheet 4 Friction Comparison
Students will demonstrate that it takes more force to move an object if there is more friction or more mass by:
Collecting and analyzing friction data
Read/analyze article: “Discovery of Friction”
Jan 9 & 13
1.3 Forces in Action
Focus Question: How do multiply forces affect motion?
NB Sheets: 5 &6 (Forces on Carts A & B) 7 Response Sheet Inv 1
Students will demonstrate that if the forces are not balanced an object will move in the direction of the greater force by:
Testing and analyzing the effect of different forces on carts movements
Practice calculating net forces
Watch the video: “Forces”
Read and analyze article: “Net Force”

I've included a link for the students to access the FOSS Web for science class. This is a general access for all students at this time. Individual students access will be available at a later date.
