BELL WORK! You will need a sheet of notebook paper. Create a KLW Chart on your notebook paper. K= Know Write what you already knew about Earth’s atmosphere, gravity, or magnetic fields. L= Learn Write down at least 3 things you have learned over the past week. W= Want to Know Write down some things you’d still like to learn about the current topics.

This Week in Science…

Today’s Goal… I can compare the magnetic field lines of a bar magnet, Earth, and an electromagnet.

What is an electromagnet?

Electromagnet Field Lines

What is an electromagnet? Iron Core Battery Wire Coils

How do you strengthen an electromagnet? To strengthen an electromagnet, you could Wrap the wire coils around an iron core Add more coils Use a bigger battery

Build an Electromagnet Lab Make sure you following the directions very carefully. Record accurate data. Fill out your lab sheet as you go. Every group needs a direction reader. Be sure to listen as the direction reader tells you what to do.
