Use a timeline to identify the sequence and time required for building and breaking down of geologic features on the Earth. To observe a magnetic force an interaction between a magnetic field and a material such as iron must occur. Electricity is a form of energy. Static electricity is a result of objects being electrically charged through friction. Current electricity can be generated and transmitted through pathways.
Some materials are capable of carrying electricity more effectively than other materials.
Students will understand that magnetism can be observed when there is an interaction between the magnetic fields of magnets or between a magnet and materials made of iron. Investigate and compare the behavior of magnetism using magnets. Investigate how magnets will both attract and repel other magnets. Compare permanent and electro-magnets. Conduct an investigation on the effects of a magnet on a compass.
