This video explains the difference between meteoroids, meteors, and meteorites. They discuss the history of meteors and how they were once believed to be fireballs or signs of impending doom. The video also covers the origin and...

👉 Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph...

This video explores the origins and history of Valentine's Day, tracing it back to the ancient Roman festival of Lupercalia. It highlights the various legends surrounding Saint Valentine and how the holiday evolved over time to become a...

The graph of a quadratic function in a single variable is always a parabola, and when the function is written in vertex form, we can identify the coordinates of the parabola's vertex simply by looking at the function. But how is the...

Water is the life-blood of Yosemite National Park. The Tuolumne and Merced rivers water some of the most productive farmland on the Earth, and urban dwellers throughout the state depend on the Sierra Nevada snowpack for their domestic...

Sometimes arithmetic operations result in fractions greater than one, called "improper" fractions. An improper fraction can be converted into a "mixed number" composed of an integer plus a "proper" fraction.

Adjectives are words that modify the meaning of nouns or pronouns. They usually come before a noun. There is an order of adjectives that we usually follow. In this lesson, Mr. P./Marc will provide a table showing the exact order of...

A general introduction to the major sociological perspectives.

In this lesson, students will learn how to plot points on a coordinate grid system. They will understand that coordinates are like addresses for points on a plane and are written in parentheses, with the X coordinate first and the Y...

In this video, students learn how to determine if two figures are congruent by using a sequence of transformations. Learn about three types of rigid transformations - rotations, reflections, and translations - and understand how to apply...

This video explains how to represent a situation involving two runners, Mark and Paul, on a coordinate plane. By graphing ordered pairs, we can visually compare their running times and distances. The video demonstrates how to plot...

This video explores an example of a family driving at different speeds throughout a trip. By calculating the average rate of speed for each segment of the journey, a more accurate understanding of the trip is obtained. This lesson...

In this video, students learn how to identify a proportional relationship by understanding the meaning of the origin on a graph. The video explains that a proportional relationship is characterized by a straight line on the graph and a...

Graphing lines in algebra.

Perpendicular lines have slopes which are negative reciprocals of each other, but why?

Fossils discovered within rocks led scientists to begin to change their ideas on the creation of life on earth. Charles Darwin's 5 year voyage on HMS Beagle led to him collecting different flora and fauna from the countries he visited....

This video explains how to determine the constant of proportionality from a graph. It demonstrates the process using an example of time and distance. The constant of proportionality can be found by finding the ratio of y to x, and it...

Come on a treasure hunt with the NUMBEROCK crew as we explore a deserted island and follow the coordinates on an ancient coordinate plane treasure map that leads our favorite characters to modern treasures!

In this online video we will learn Introduction to coordinate geometry, what is cartesian coordinate system, quadrants, x-axis, y-axis in plane

Come on a treasure hunt with the NUMBEROCK crew as they explore a deserted island and follow the coordinates on an ancient coordinate plane treasure map that leads our favorite characters to modern treasures! The ordered pairs are...

Which is actually pretty much what it also means in maths. When a shape is transformed, it’s appearance changes. It can be rotated… reflected… translated… or enlarged. In maths, we learn about these 4 different types of transformation…...

Linear equations of the form y = mx+b can describe any non-vertical line in the Cartesian plane. The constant m determines the line's slope, and the constant b determines the y intercept and thus the line's vertical position.

In this video, students are taught how to find the trigonometric coordinates for angles of 30 and 60 degrees on the unit circle using special right triangles. The lesson explains the concept of the unit circle, equilateral triangles, and...

In This Episode, Tyler Teaches Us About Plotting Lines using Slope-Intercept
