Study magnets!
Have you seen a magnet stuck to a refrigerator? Magnets
stick to some things, such as metal. But they do not stick to
everything.
Magnets have two ends. They are called poles. One is
its north pole. The other is its south pole. A magnetic force
pushes or pulls magnets. The magnetic force is strongest at 5
a magnet’s poles. Opposite poles of magnets attract, or pull
together. If the poles are the same, magnets repel, or push
away from each other.
This push and pull makes magnets useful. Toy trains
connect with magnets. Some doors pull closed with magnets.
And recycling centers use big magnets to pull metal from
large trash piles. How can you learn more about magnets?

Seven Science Steps
Doing a science experiment is a fun way to discover new facts!
An experiment follows steps to find answers to science questions.
This book has experiments to help you learn about magnets.
You will follow the same seven steps in each experiment:

Seven Steps
1. research: Figure out the facts before you
get started.
2. Question: What do you want to learn?
3. guess: Make a prediction. What do you think will
happen in the experiment?
4. gather: Find the supplies you need for your experiment.
5. experiment: Follow the directions.

6. review: Look at the results of the experiment.
7. Conclusion: The experiment is done. Now it is time to
reach a conclusion. Was your prediction right?
Are you ready to become a scientist? Let’s experiment to learn
about magnets!
