I am learning about magnetic forces, so I can determine which objects magnetic forces can pass through. Success Criteria: I’ll know I’m successful when I can explain how the thickness of a material affects magnetic forces. *Consider giving students different thicknesses of paper such as cardstock, cardboard, newspaper, etc. to I am learning about Earth’s magnetic feld, so I can understand how Earth is similar to a magnet. Success Criteria: I’ll know I’m successful when I can explain how a compass works. I am learning about Electromagnets so I can explain how they work. Success Criteria: I’ll know I’m successful when I can build an electromagnet or use an electromagnet.
