Unit Outcomes
• IF3.1 ~ Investigate the effects and
applications of magnetic forces on a
variety of materials. (draft)
• IF3.2 ~ Investigate the effects and
applications of static electric forces on a
variety of materials. (draft)
Unit Overview
• 14 lessons
– 9 lessons for Magnets
– 3 lessons for Electricity
– 2 lessons for review & test
• Lots of hands on, interactive experiments and
labs to engage, explore, explain, elaborate, and
evaluate the in depth aspects of magnets and
static electricity.
• Students will be working independently and
cooperatively with their classmates during this
unit as they study and create their own
magnets and electric devices from common
materials.
• All info, notes, labs, and handouts are all
included and ready to be photocopied.
Lesson #1
•
•
•
Make a KWL chart with the class what they
know and want to know about magnets
Show & explain the types of magnets and their
uses
Magnetic or Nonmagnetic?? Experiment
– Given items to predict whether they are magnetic
or not and in groups test them with various types
and strengths of magnets
•
Complete KWL chart with what they learned
Lesson #2
• Read: That Magnetic Dog by: Bruce Whatley
• What is a Magnet?, What items are Magnetic? &
Poles fill-in-the-blank notes
• Flying Butterflies exploration
• Tug-a-war with class and explain how it is like
magnets
Lesson #3
• Magnet’s Magnetic Field
• Experimenting with iron filing to see the
magnetic field of the magnet
• Draw their magnet and the field that the iron
filings showed
• Magnetic Lines of Force notes
Lesson #4
• Read: Franklin is Lost ~ Paulette Bourgeois
• Earth is a natural magnet
• Make a Compass by making a temporary
magnet
• POE chart
• Earth’s Magnetism notes handout
Lesson #5
• CENTRES
– #1~Can you rescue a paperclip from a glass of water without
getting wet?
– #2~ Will the paperclip climb the ruler?
– #3~Can you guide a paperclip through the maze?
– #4~Interactive website: Engineering Interact- Magnetic Forces
– #5~ Brainpop movie & Quiz- Magnetism
• Students will fill out a question sheet with
one question per centre to show what they
learned
Lesson #6
• Magnet’s Strength fill-in-the-blank notes
• 2 Measuring a Magnet’s Strength
experiments
• Compare 2 magnets in Venn Diagram by
strength, shape, length of force, etc.
Lesson #7
• Read ‘Magnets’ by Ron Brown lyrics
• Discuss familiar uses of magnets
• Magnets can wreck things – Magnetic
Storage info
• Distorting Sound experiment
• Read ‘Magnets’ by Ron Brown lyrics one
more time but like a rap song this time
Lesson #8
• Bill Nye: The Science Guy – Magnetism
video
• Students will answer the question sheet
while they are watching the video
Lesson #9
• Making Refrigerator Magnets
• Students will be moulding the already prepared
dough into a shape that fits into a theme in the
classroom
• Bake, paint, & share with class
Lesson #10
• Talk about Static Electricity
• Experiments are a class demonstration:
– On End
– Charged or Not Charged
– Making Sparks
• Static Electricity notes
• Summarize and explain experiments
Lesson #11
• Brainstorm with the class on a web what
machines that they own use batteries
• Making a Circuit experiment
• insulators, conductors, circuits matching
handout
Lesson #12
• Potato Power
• Make a Potato Battery to run a calculator
with guided instruction
• POE chart in science duotang
• Explain experiment/why it happened?
Lesson #13
• ‘Jeopardy’ theme song
• Play ‘Jeopardy’ keeping score for the
teams
• Tally points review any questions they
don’t understand for test next class
Lesson #14
• Unit Test
– Handout
– Students write
– Hand in and read silently
Hope you have the opportunity to
use my unit and enjoy!! 
