The Pearl Exchange is a hands-on experiential learning activity that shows how buyers and sellers determine equilibrium price in a market. It also shows how changes in a market will lead to shortages or surpluses and result in changes in...

In this lesson, students will learn about the different forms of quadratic functions and how they can provide valuable information about the function. They will explore the vertex form of a quadratic function and understand how it can...

In this video, students learn how to find the maximum height of a baseball hit into the air by writing its quadratic function equation in vertex form. By completing the square, they can easily identify the vertex of the parabolic...

In this video, the teacher explains how writing a parabola in vertex form helps solve application problems. They go through the process of completing the square to find the vertex form of a quadratic equation. The video also demonstrates...

Learn about the energy levels and electronic configurations of atoms of different elements in this video from the Properties of Matter chapter of the Virtual School GCSE Chemistry.

Learn about the science behind nature's most spectacular light show. Caused by the sun, solar wind interacts with Earth's magnetic shield and reacts with gas molecules creating the visible aurora.

Learn the basics about Energy Levels and Electron Configuration. Where do you find energy levels? How do you recognize electron configuration? Find out more in this video!

Build a simulated market from scratch and see supply and demand curves emerge.

In this video, the teacher explains how to use different forms of quadratic functions to solve problems. They review the three equal forms of quadratic functions: standard form, vertex form, and factored form. The teacher demonstrates...

In this lesson, students will learn how to find the vertex of a quadratic equation and determine whether it is a maximum or minimum point. By analyzing the coefficient of the squared term, students can determine if the parabola opens...

This video explains how to graph a line using the slope and Y intercept. Review examples and walk through the process step by step. The video covers topics such as rate of change, plotting points, and finding maximum and minimum values....

Newton's first law tells us that an object in motion will remain in motion, but we don't really see that on earth, do we? If you throw a ball, or push a hockey puck, these things do eventually stop. Why? To answer this we must learn...
