Do you believe that your race correlates to your skin tone? Because that wasn't always the case. So how did Americans come to believe that race equals certain visible physical characteristics such as skin color and hair? And why is it...

When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules from each other. This is known as specific latent heat. Specific latent heat is defined as the...

In This Episode, Tyler Teaches Us About Finding and Plotting Slope Intercept Form from Standard Form

In this lesson, students will learn how to estimate solutions to systems of equations by graphing when both equations are in slope intercept form. They will understand the concepts of slope intercept form and how to graph linear...

This video provides a concise overview of human embryonic development, starting from fertilization and the formation of a zygote, to the development of germ layers, major body systems, and finally the birth process. It emphasizes the...

This video explains how to interpret scatter plots by calculating the rate of change on the graph. Learn how to find the slope or rate of change by choosing two points on the line and determining the vertical and horizontal distances....

What is it to take the derivative of a function? Let's derive and define the power rule, so that we can take the derivative of simple polynomials.

Mapping part 5/10

In this video, students will learn how to determine the rate of change in linear relationships by comparing slopes on a graph. The video explains that rate of change is a ratio that compares the change in output to the change in input,...

In this live-action program viewers will learn that the scientific method is a disciplined, systematic way of asking and answering questions about the physical world. Students will come to understand each step of the scientific method...

In this lesson, students learn how to interpret the rate of change of a line of best fit by calculating the slope. They review the concept of slope as the ratio of change in Y to change in X, also known as rise over run. The lesson...

From fertilization, to germination, to growth, to death, this series of videos explores the life cycles of plants. The means by which plants respond to their environment is also highlighted. Specific attention is paid to development of...

According to a paper published in the journal Nature, researchers extracted ice core data in order to examine rates of surface melt and run-off in Greenland.

Planets Set: 3. This clip presents a simplified overview of the Earth's geography and biomes.

The Sun, Water Cycle, & Climate shows us how the sun produces heat to drive the water cycle. It's made clear that the water cycle continues in the absence of sunlight or heat. We learn how the two components of climate- temperature and...
