By exploring magnets, students are indirectly introduced to the idea that there are forces that occur on Earth which cannot be seen. This idea can then be developed into an understanding that objects, such as the Earth or electrically charged objects, can pull on other objects. The Next Generation Science Standards (NGSS) addressed:
MS-PS2-3 Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
MS-PS2-5: 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.
