Students can use the Iron Filings to plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
Students can use the Iron Filings to investigate and analyze data obtained from testing different materials to determine which materials have properties that are best suited for an intended purpose.
Students can use the Iron Filings define a simple design problem that can be solved by applying scientific ideas about magnets.
Students can do an activity with the Iron Filings with a Bar Magnet to analyze and interpret data from maps to describe patterns of Earth's features.
Students can use the Iron Filings to gather and make sense of information during an investigation.
Students can use the Iron Filings to ask questions about data to determine the factors that affect the strength of magnetic forces.
Students can use the Iron Filings 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.
When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object.
Students can do an activity with the Iron Filings with a Bar Magnet to construct an explanation based on evidence for how geoscience's processes have changed Earth's surface at varying time and spatial scales.
The magnetic object and the Iron Filings can be used to develop and model how two objects interacting through magnetic fields, illustrates the forces between objects and the changes in energy of the objects due to the interaction.
Students can use the Iron Filings in their experiments to see the attraction (pull) or repulsion (push) of different strengths or directions or magnetic forces. Use different strength magnets to show the amount of pull exhibited.
Students can do an activity with the Iron Filings and a Bar Magnet to model the Earth's magnet field. Place the magnet on a flat surface, cover it with white paper, slowing sprinkle the iron filings to reveal the magnetic field. This helps them to better understand the north/south identification on maps.
The above activity can also model how over the course of Earth's history, the magnetic field of the poles have swapped location, based on magnetic readings of the Atlantic Ocean floor.
Matter can be described and classified by its observable properties. Iron Filings are very interactive with any magnets for this investigation.
Each pure substance has characteristic physical and chemical properties that can be used to identify it.
Students can use the Iron Filings to develop a model to describe a phenomenon.
