No wonder Coulomb's law would spark your interest! In this simulation, you will learn how charges interact through the electrostatic force, how different factors influence the strength of that force, and how to determine its direction.

Dr. One's hair-raising new look

Your helpful science assistant, Dr. One, is considering powder coating their case, a process that involves electrostatic forces. Join the lab to learn all about the law that governs those forces: Coulomb's law. Use scientific equipment to measure different values of the electrostatic force and play this sim's minigames to figure out the effect of the charges' signs on its direction.

Charges, distances, and the electrostatic force

Measure, collect, and graph data to figure out the effect of the value of distance and charge on the electrostatic force using realistic scientific equipment, experimenting freely with different values of the parameters. Visualize the impact of the charges' signs on the force through fun graphics and interactive activities. This simulation allows the student to measure the effect of Coulomb's law using a realistic lab setup without the risks electricity entails in real life. Starting from the measurable physical phenomena, the simulation guides the student through increasing stages of mathematization, highlighting the physical meaning behind the algebraic expression of Coulomb's law.

Master Coulomb's law

By the end of the sim, you will have built a qualitative and quantitative understanding of Coulomb's law through the interactive activities in the lab. Do you know what the force between the two charges tells us about Dr. One's new coating?

## For Science Programs Providing a Learning Advantage

Associate Professor
North Dakota State College of Science

“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”

Lewis Mattin
PhD
Lecturer in Human Physiology
University of Westminster

"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.

Melody McGill
Curriculum Coordinator
Modesto City Schools

"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."

Kyle Hammon
Wenatchee Valley College

"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”

Dr. Melody Esfandiari
Chemistry Lecturer
San José State University

"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

Dr. Stuart Goodall
Lecturer
Northumbria University

“The Labster simulations get students to do things, and they're not just sitting there consuming a webinar where their mind can drift. They become an active participant in that learning experience.”

How do students access Labster?

Labster can be integrated within a school's LMS (Learning Management System), and students can access it like any other assignment in their LMS. If your Institution does not choose an LMS integration, students will log in to Labster's Course Manager once they have an account created. Your institution will decide the access method during the sales process.

How is Labster purchased?

Labster is only available for purchase by faculty and administration at academic institutions. To procure Labster, simply reach out to us on our website. Schedule a demo, book a meeting to discuss pricing, start a free trial, or simply fill out our contact form.

How is Labster different from other learning solutions?

Labster simulations are created by real scientists and designed with unparalleled interactivity. Unlike point and click competitors, Labster simulations immerse students and encourage mastery through active learning.

What types of courses does Labster support?

Labster supports a wide range of courses at the high school and university level across fields in biology, chemistry and physics. Some simulations mimic lab procedures with high fidelity to train foundational skills, while others are meant to bring theory to life through interactive scenarios.
