Teacher takes 2 magnets from the foss kit, the type that is cylindrical and looks like a washer. Place the magnets on a pencil with similar poles facing each other. Ask the students if they know why the magnets aren't touching each other. do not give the answer yet. Instead, shows students a video on Maglev trains. Show your display again and ask if they figured out why the magnets did not attached to each other now.
what do you know about magnets? (respond in writing and share out)
Students will generate questions on to why the magnets did not touch each other.
Teacher can then teach about poles of a magnet. allow students to use two magnets on a pencil ( the ones in a Foss Kit which has the cylindrical magnets) where they would attach or repel depending on pole position.
Allow the students to discover for themselves how the poles on a magnet work.
2 objects that attach to magnets
Have the students write a hypothesis on objects that will attach to magnets.
Hand out various objects for students to test which will ones will attach to magnets.
Compare their result to the hypothesis.
students generate questions as to why certain objects attached and others didn't.
3 Dig Deeper
Handout the worksheet from Go-Math stem
Worksheet has 3 short stories about Maglev train, MRI, and electromagnet teacher will need to provide some prior knowledge about MRI for the students.
1-What must an object contained in order to attach to a magnet and how did your hypothesis compare to your result?
2-what have you discovered about magnets?
Next step: use a D battery and coil to teach how to create an electromagnet much like the one shown on the YouTube video.
Students read and answer the questions on how magnets are used in our everyday life.
Students will also go on formative to answer the short response questions about the lesson
