In 2010, the Deepwater Horizon oil spill in the Gulf of Mexico became the largest in United States history. Killing 11 people, it injured people, ecosystems, and economies. This film explores the timeline of the spill, the cleanup,...

An introductory lecture to the basics of Andrew Jackson's Indian Removal Act.

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...

Facebook Marketplace is a fantastic place for individuals to find items at a great price from locals and vendors alike. In this video, I will break down for you everything you need to navigate and buy on Facebook Marketplace via mobile...

Learn how to write an equation that represents the proportional relationship between distance and time. Review how to find the unit rate and emphasize that distance should be divided by time to get the correct ratio. Using a table and...

We've got a great way to work in math skills into your next Phys Ed Class, with Numbered Junior Spots! These activities are a great way to reinforce odds and evens, addition and subtraction or any number of other problems you can come up...

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...

In this video, the teacher explains how to use scale maps and scale models to find the actual distance between two points or the dimensions of an object. They demonstrate how to calculate the distance using unit rates and provide...

In this lesson, students will learn how to compare prices represented in different ways and how to determine the better buy using unit rates. They will also learn how to compare the speeds of two trains by comparing their unit rates. By...

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...

Mr. Beat compares and contrasts Los Angeles and New York, the two largest and most influential cities in the United States.

In this video, students will learn about unit rates by exploring real-world examples. The video explains that ratios compare numbers, while rates compare different units. It provides examples such as comparing the price of a gallon of...

In this lesson, students will learn how to solve rate problems by using multiplicative reasoning. They will understand the concept of equivalent rates and how to set up a table to organize information.

In this video, the teacher explains how to simplify a rate to its unit rate using diagrams. They emphasize that a unit rate is a comparison of one quantity to another, reduced to something over 1. The teacher provides examples and...

If you're familiar with John Green's debut novel, looking for Alaska, then you know the reference to Miles' name (Miles to go before I sleep) comes from a Robert Frost poem. But, did you know that diving into this poem revels just how...

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,...

A fun music video featuring airplane condensation trails, also known as vapor trails. These common man-made clouds form behind high-flying aircraft as skinny lines but then they may spread out to merge with natural cirrus clouds.

In this lesson, students will learn about rates and their connection to ratios. The video explains that rates are a type of ratio that compare two or more quantities of different measures, such as miles per hour or price per pound. It...

The area of Southern Washington State around the Mount St. Helens Volcano has been nearly devoid of life since the 1980 eruption - making it a biology lab like no other as scientists observe it springing back to life. The regenerating...

In this lesson, mathematicians learn how to divide whole numbers by fractions using models. They are taught to think of the division as how many groups of the fraction are in the whole number.

In this video, students learn how to find a fractional unit rate by using a graph. The teacher explains that unit rates can be expressed as fractions instead of decimals, and provides examples of how to calculate unit rates from graphs....

In Rob's journey through the pear orchard he'll discover that ten ones make ten, ten tens make one hundred, and ten hundreds make on thousand. Then he undertakes an epic bike ride - 100 miles! Holy Moly! As his trip nears its end, he...
