Learn all about ellipses for conic sections. We will discuss all the essential definitions such as center, foci, vertices, co-vertices, major axis and minor axis. We will also discuss the essential processes such as how to graph and...

👉 We will explore how to evaluate the limit at infinity. When evaluating the limit at infinity or negative infinity we are interested to know where is the graph going right and left. This is also commonly explored as end behavior of the...

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...

A horizontal spring is attached to a cord, the cord goes over a pulley, and a 0.025 kg mass is attached to the cord. If the spring is stretched by 0.045 m, what is the spring constant of the spring?

What are the equations needed to solve for the X direction? Projectile Motion, Part 2

What are the equations needed to solve for the Y direction? Projectile Motion, Part 3

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt looks at the science of projectile motion and...

In this video students will learn about unconformities and how they help geologists to discover episodes of volcanism, uplift, erosion and deposition that provide evidence for plate tectonics during Earth's history. Through video and...

In this video, students will learn about the differences between bar graphs and picture graphs. They will understand that bar graphs use bars and a scale to represent data, while picture graphs use symbols and a key.

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. 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...
