Data is just waiting for scholars to analyze. By viewing a video of a data analyst explaining his job and the math that surrounds it, scholars begin a lesson on data collection and analysis. Groups develop questions for a poll on teenage...

Some days seem longer than others, but recent research proves our day actually lasts much longer than in the past. SciShow Space shares recent research on the length of Earth days and how this data confirms past research with much more...

So what is an engineer? An informative video provides a brief introduction to engineering. It shows what kids think an engineer is and what engineers think of the profession.

Hardware and software go hand in hand. The last installment of a five-part series explains the relationship between computer hardware and software. It turns out that the computer's operating system provides the link between the two.

Sal continues to look at changing the length of compounding time, from daily to hourly compounding interest. Now he is able to show that compounding 100% annual interest converges on the number 2.71É or e as the number of compounding...

This video focuses on rational expressions and completes Sal's lecture series on working with and solving this particular type of equation. Its length would be ideal for a computer lab visit or homework assignment (in conjunction with a...

Here is a fairly basic video that uses three equations, each written in slope-intercept form, to determine whether the lines are parallel. Sal graphs each equation on the same coordinate plane to show how their slopes compare. The video...

Provide your algebra class with some review of rational expressions in this video. Sal uses several sample problems to demonstrate the process, and his explanations are clear and easy to follow.

Adding two polynomials begins with simplifying when possible. Sal demonstrates the process he uses to combine like terms and explains why the process works. This video would be great for those who need a quick refresher.

This video provides a reasonable explanation for blossoming mathematicians, explaining the difference between average and central tendency, as well as arithmetic mean, median, and mode. Those who haven't grasped these concepts in algebra...

Continue your lecture on radical equations with this video, which features Sal solving a few more problems with his classic clarity and understandable way. Young mathematicians will benefit immensely from seeing his cool hand guide the...

Starting with a set of values for the x and y variables, this video shows how to tell whether these points determine a linear or non-linear function. Sal first defines linear functions in terms of the change in y over the change in x,...

This short video looks at different points on a coordinate plane and answers a question about whether these points could represent a function. The answer is determined by looking at each point individually to determine whether, given a...

Here is a great video explaining multiplying a fraction by a whole number. Sal shows students how to put a whole number over 1 to multiply it by a fraction. He simplifies his answer and writes it as a mixed number.

When you have to flow, you have to flow. The lesson introduces class members to microfluidic devices and their uses in medicine. They watch a short video on how the diameter affects the rate of flow. The worksheet has individuals...
