Magnetic Poles and Fields

Lab Brief #2

🎯 Your mission

Predict it first. Then prove yourself right (or wrong).

⚡ The twist

Nature loves to surprise the careful watcher.

What you'll learn

Magnets have north and south poles. Opposite poles attract and like poles repel. The magnetic field is strongest at the poles and gets weaker with distance.

Key words

work
Using force to move an object over a distance.
electromagnetic
Related to electricity and magnetism working together, like light and radio waves.

Make a hypothesis first

Before you start: write down what you think will happen, and why.

Say your guess out loud — then find out if you were right.

Get ready

🧰 What you need

rubber bands

⚠️ Safety first

Have an adult check your set-up before you start, and tidy everything away afterwards.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Construct a catapult from popsicle sticks and rubber bands. Launch a marshmallow from different angles and measure the distance. Find the angle that gives the longest launch.

Step 3 of 4 · Observe

Watch carefully for any changes and note the time.

Step 4 of 4 · Record

Create a data table to organize your measurements.
