WE BUILD CUSTOM KITS!
Students will benefit from demonstrations using Ferrofluid. Ferrofluid can be quite messy if handled recklessly. This kit is recommended for hands-on use with students in middle school and older.
Students can use Ferrofluid to gather and make sense of information during an investigation.
Students can use the Ferrofluid in an investigation to ask questions about data to determine the factors that affect the strength of magnetic forces.
Students can use the Ferrofluid 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.
Students can do an activity with the Ferrofluid 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 Ferrofluid 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.
Using a variety of magnet shapes and the Ferrofluid will allow students to observe the various shapes magnetic field can take.
When a bar magnet is used, it can model how the magnetic properties of the North and South Poles of the Earth. Students can use this information to 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. Rotate the magnet 180 degrees to model the geologic history of the Earth's magnetic field.
Each pure substance has characteristic physical and chemical properties that can be used to identify it.
Investigations using Ferrofluid and magnets will demonstrate the attraction and repulsion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects. Use the Ferromagnetic Liquid to show the magnetic field.
Students can use the Ferrofluid to develop a model to describe a phenomenon. The students will be engaged in learning as they visualize various magnetic fields.
