If you’re teaching a course in physics, perhaps you’re looking for resources to help you introduce or reinforce fundamental physics lab techniques that every student will benefit from.
There are many lab techniques that deal with matter, energy, and their interactions, but we’ve identified six that students would greatly benefit from knowing.
We’ve also identified six Labster virtual labs that help you teach each technique. Not only can your physics students learn the methods, but they can also have fun along the way!
A circuit is a closed loop that electrons can travel in. A source of power, such as a battery, provides electrical energy in the circuit. Generally, some appliances use electricity in the circuit that may provide light, heat, or mechanical energy.
Electrical Resistance: Apply Ohm's law to simple circuits virtual lab
Students will learn how resistors affect electric current and how modifying the size of a resistor can modify its resistance. They’ll also get the chance to build their own circuit to repair a broken radio to contact their scientist colleagues.
A simple pendulum assumes the following simplifications:
Law of Universal Gravitation: Use gravity to orbit the moon virtual lab
To deduce Newton’s Law of Gravitation, students will investigate how gravitational acceleration depends on the masses of objects and the distance between them. Students will learn about the difference between mass and weight. Sir Isaac Newton himself will get on the scales, and you will perform a pendulum experiment that will let you define the gravitational acceleration near the surface of the Earth.
A free-body diagram is a drawing of all external forces acting on a body. It is a useful tool for analyzing many problems related to forces and motion.
Labster’s virtual lab that teaches the free-body diagrams is:Forces and Free-body Diagrams: Learn how to navigate a drone virtual lab
Students move as a result of forces acting upon them. In this simulation, they’ll learn the basics of common forces as they experience them in everyday life. They’ll visualize the reaction of an object in a given condition using the free-body diagrams.
This concept is an attractive force that occurs between two masses. There’s a gravitational force between every object in the universe.
The Gravitational Field: The aliens are coming virtual lab
Students will meet the extraterrestrial Pondus and help him study Earth's gravity. They’ll learn about the gravitational field and acceleration at Earth's surface and anywhere in space and help Pondus understand if Earth is more suitable than his planet for space travel. The mass of his planet is so big that he needs a huge thrust to escape its gravitational pull.
Quasi-elastic neutron scattering (QENS) is a technique used to measure dynamic processes in solid materials such as plastic, ceramics, and gels.
Quasi-Elastic Neutron Scattering virtual lab
Students will perform a QENS experiment at a research facility while helping a group of scientists in the Arctic. Observe the structure of atomic layers inside a battery and see how some atoms move when it discharges.
In summary, here are the six physics lab techniques and their accompanying virtual labs:
