Lesson 1: Barrier Breakout
Learning Objective
Students will observe and conclude that magnetic force can pass through non-magnetic materials like paper, plastic, and wood.
The Hook
Place a paperclip on a desk. Hold a strong magnet underneath. Move the clip without touching it. Ask: "Is this magic, or science?"
Lesson Flow
5-10 min
Introduction & Hook
Demonstrate the "magic" desk trick. Introduce the term "Invisible Force." Explain that today we are testing what blocks this force.
20 min
Workshop: Barrier Stations
Students work in pairs. They use their worksheet to test 4 specific materials: Paper, Cardboard, Plastic, and Wood (Desk). Encourage them to find a 5th "Mystery Material" in the room.
10 min
Group Debrief
Ask: "Did anything stop the magnet?" Discuss why these materials didn't block it. Key takeaway: Magnetic fields act through non-magnetic barriers.
Key Discussion Questions
"What happens to the paperclip if the barrier is too thick?"
"Can you feel the magnet pulling even if it's not touching the clip?"
"What do you think would happen if we used a metal barrier like a lunchbox?" (Lead to future investigation)
Support
Provide pre-cut barriers for easier handling. Use high-contrast magnets (red/blue) to help students orient north/south poles if they get stuck.
Challenge
Have students stack sheets of paper to find the exact "breaking point" where the thickness of the barrier finally stops the magnetic force.

Lab Journal Example
What did we learn?
The magnetic force is strongest at the ends (poles) and spreads out in a beautiful pattern called the Magnetic Field.

Invisible Art Teacher Guide Teacher Facilitation Guide
Lesson 2: Invisible Art (Visualizing Fields)
Learning Objective
Students will identify that magnetic force exists in a specific pattern called a "field" and that the force is strongest at the poles.
Safety Tip
Always use sealed cases for iron filings. If loose filings are used, they can ruin magnets and get into eyes/skin. Keep cases closed!
Lesson Flow
5 min
Introduction
"If we can't see the air, how do we know it's there? (Wind, leaves moving). If we can't see magnetism, how do we know where it is?"
10 min
Modeling the Discovery
Show students how to gently tap the side of the filing case to distribute the filings before placing the magnet. Demonstrate how to trace the curved lines.
20 min
Artistic Investigation
Students sketch the field of a single bar magnet. Once finished, they should try the "Mystery Challenge" with two magnets. Encourage them to see how fields interact (Push/Pull).
Scientific Observation "Look-Fors"
Filings clustering at the North and South poles.
Curved lines connecting the poles.
Clear space further away from the magnet (where force is weak).
Interaction between two magnets (fields blending or avoiding).
Troubleshooting
"Everything is just a big blob!" → Students likely have the magnet too close or the filings are too clumped. Shake gently and hold the magnet slightly further away or use a weaker magnet.
"It's too hard to draw." → Remind students they aren't drawing every piece of dust, just the paths the dust takes.

Lesson 3: Strength Showdown
Learning Objective
Students will measure and compare the strength of different magnets using a standard unit (paperclips) and realize that size does not always determine strength.
Material Prep
Provide a variety of magnets: large ceramic bar magnets, small but powerful neodymium (silver) magnets, and flexible magnetic strips. Ensure each group has 50+ paperclips.
Lesson Flow
5 min
Prediction Phase
"Look at these magnets. Which one looks the strongest? Why do you think so?" Have students record their predictions first.
25 min
The Chain Workshop
Model the "Chain Lift": Hold the magnet and add paperclips one by one in a hanging line. The count is the last clip held before the chain breaks. Students rotate through testing different magnets.
10 min
Data Discussion
Gather the class. Ask: "Were you surprised? Which magnet was the secret superhero?" Focus on the tiny silver magnets (neodymium) vs large bar magnets.
Teaching the Concept: Strength
Explain that magnets are made of different materials. Some "pull" harder than others, even if they are small. This is like a tiny ant being able to carry a big leaf—strength isn't just about being big!
Math Connection
This lesson uses counting, comparing numbers (greater than/less than), and simple graphing (1:1 correspondence in the boxes). Ask students: "How many MORE clips did the silver magnet hold than the bar magnet?"
Support
Work in pairs where one student holds the magnet and the other adds/counts the clips. Use jumbo paperclips if fine motor skills are a challenge.
Challenge
Have students test if the strength changes if they put a piece of paper between the magnet and the first clip. Does the chain get shorter?
Magnetic Mazes Slides Magnetic Mazes
Can you finish the path without touching it?
The Invisible Pilot
You are going to drive a paperclip through a maze. But there is a catch: You can only touch the magnet UNDER the plate!
🏎️ 📎
Step-by-Step
01
Draw a path with a START and a FINISH.
02
Place your paperclip "car" at the start line.
03
Guide it through using the magnet underneath!
Pro Scientist Tips
"Move slow and steady! If you go too fast, the clip will fall off the force."
"Keep the magnet touching the bottom of the plate at all times."

Lesson 4: Magnetic Mazes
Learning Objective
Students will apply their knowledge of magnetic forces acting through barriers by designing and navigating a paperclip through a maze using a magnet.
Materials Needed
Paper Plates (or the Worksheet)
Paperclips
Strong Magnets (Bar or Neodymium)
Markers/Crayons
Lesson Flow
10 min
Design Phase
"Design a path that isn't too narrow. Think about where your traveler (paperclip) will start and finish."
20 min
The Great Race
Students test their own mazes. They must move the clip from Start to Finish without touching the clip with their hands. Encourage "Slow Science" (fine motor control).
10 min
Peer Testing & Swap
Students swap mazes with a partner. This provides a "Peer Review" where they can see if others find their maze too easy or too hard.
Science Behind the Fun
This activity reinforces that the magnetic field is a continuous link. If the magnet moves too fast, the friction of the paper and the air might overcome the magnetic pull, "breaking" the connection. This helps students understand that force has limits.
Support
Provide a pre-drawn maze for students who struggle with fine motor planning. Use a larger object like a small magnetic ball if paperclips are too fiddly.
Challenge
Add "Obstacles" to the maze—draw small circles. If the paperclip touches an obstacle, they have to go back to the start! Or try navigating through two plates stacked together.

What do you think?
YES
The pull will work through water.
NO
The water will block the force.

Lesson 5: Underwater Fishing
Learning Objective
Students will investigate if water blocks magnetic forces and conclude that magnetic fields can act through liquid barriers.
Setup Tips
Shallow plastic bins with 2-3 inches of water.
Ensure magnets are wiped dry after the lesson to prevent rust.
Laminated "mazes" or maps can be placed at the bottom for extra fun.
Lesson Flow

The Great Wet Debate
"If you are underwater in a pool, you move slower. Does a magnet's pull move slower too? Will the water get in the way?"
20 min
Fishing Expedition
Students work in small groups at water stations. They try to "fish" for paperclips, magnetic marbles, or small washers. Challenge them to see if they can catch a fish from the surface without putting the magnet *into* the water yet.
15 min
Sequence Reflection
This is the final lesson. Review all the barriers tested: Paper, Desk, Air, Plastic, and now Water. Ask: "Is there anything we've found that completely stops a magnet?"
Big Picture: Action at a Distance
Remind students that magnetism doesn't need "stuff" to travel through—it even works in the vacuum of space! The fact that it works through water, paper, and wood shows that the field is a force that doesn't need a physical connection.
Magnet Master Graduation
Have each student name one thing they learned about magnets before they "graduate" from the Magnet Lab. They can use their final worksheet as a certificate of completion!
Support
Use magnets with long handles (wand magnets) to keep hands dry if needed. Provide a checklist of items to "catch."
Challenge
Try to "fish" through a deeper container or through the *side* of the bin. Does the thickness of the water affect the pull?
