Grade 7 Agenda:
Draft two experimental questions related to this assignment for tomorrow.
in your science notebook
every single student
Slant: Magnetism can affect electrons - inducing an electric current
Demonstration 1: Induction flashlight
Demonstration 2: eddy current effect - magnet dropping through a copper tube
induced electric current in the tube
magnets apply force to electrons int he metal
this applies a reaction force to the magnet
slows fall of magnet
Project introduction: Investigating Magnetic Fields
STUDENT GROUPS TO FORMULATE TWO EXPERIMENTAL QUESTIONS THAT MUST ADDRESS THE FOLLOWING:
UNDERSTANDING FACTORS AFFECTING THE STRENGTH, PROPERTIES, AND NATURE OF A MAGNETIC FIELD.
You will design a scientific experiment that can answer the experimental questions you create.
