As our school continues to implement Next Generation Science Standards (NGSS), we are having to purchase items for units not taught before. I would like to purchase materials for hands-on science lessons where students will explore magnets and magnetic fields. The exploratory lessons cover NGSS Science Standards for Middle School Motion and Stability: Forces and Interactions. This standard requires students to conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.
