The melting of Earth's polar ice is incrementally warping the planet’s crust both vertically and horizontally.

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...

What are all these funny little arrows? They're vectors! And we will use them to represent every single force we discuss in physics, so we need to know how to draw them, add them, subtract them, split them up into X and Y components, the...

In this video, students learn how to interpret data by creating a line plot. The teacher explains how to locate and plot data points on a number line, and emphasizes the use of symbols to represent data.

Learn about two different ways of speaking English: one is more horizontal, where you pull your lips wide, and one is more vertical, where you drop your jaw. Which one sounds more natural? Find out in this video.

Demonstrating the difference between vertical and horizontal mass-spring systems

Ferrofluid is a liquid that displays unusual properties in the presence of a magnetic field. Watch what happens when we mix ferrofluid with the liquid from a glow stick!

In This Episode, Tyler Teaches Us About How to Solve Slope Intercept Form with Fractions

In this video, the teacher explains the concept of slope and its importance when building a roof. The slope is the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line. The teacher demonstrates...

I want to investigate how population has changed in these cities…but these numbers are just numbers. They don’t mean anything to me. In this video, we are going to discover how great bar graphs are for providing us with a clear visual,...

In this video, the teacher explains how to create a right triangle on a coordinate plane using two points that form a diagonal line segment. They review the properties of right triangles and the Pythagorean theorem, and demonstrate...

Watch how I use Behr latex house paint samples and left overs to paint a large canvas to decorate my living room.<b<b<br/>r/>r/>


KEEP CREATING! :)

In this lesson, students will learn how to read and interpret line graphs by understanding the scales. They will understand the importance of considering units and scaling when analyzing graphs. By analyzing the slope of the graph,...

In this lesson, students will learn how to locate points in space by reading the coordinates of a specific point on a coordinate plane. They will understand the concept of the X and Y axes, and how to plot and name points using ordered...

This video explains how to graph exponential functions by modeling cutting a string. It demonstrates the concept of exponential decay and shows how the length of the string decreases exponentially with each cut. The video also explains...

In this video, the teacher explains how to identify line symmetry in irregular polygons. They discuss the three options for line symmetry - horizontal, vertical, and diagonal - and emphasize the importance of having matching parts when...

A derivation of the distance formula.

This video explains how to find the distance between two points on a plane without using a measuring tool. It introduces the Pythagorean theorem and demonstrates how to create a right triangle using the given points. By applying the...

In this lesson, students will learn how to accurately describe the location of places in a city using a coordinate plane. By moving on the X and Y axes, students can plot points that represent the distance and direction of various...
