👉 You will learn how to add and subtract integers. We will work through adding and subtracting two integers up to multiple integers. We can look at adding and subtracting integers by looking at there values on a number line where there...

This live-action video program is about the term lunar cycle . The program is designed to reinforce and support a student's comprehension and retention of the term lunar cycle through use of video footage, photographs, diagrams and...

In this video, the teacher demonstrates how to solve two-step math problems using an open number line. The teacher explains the concepts of addition and subtraction using number line models and provides examples for students to follow...

Muscles are a very important type of tissue that allow us to perform many functions - from simpler actions such as blinking our eyes and chewing our food, to more complex ones such as swimming and playing football. Muscles are...

This video is an educational lesson that teaches about place value and how to understand the relationship between the different place values within a number. The lesson explains how to count the number of ones, tens, and hundreds that...

How to find the determinant of a matrix.

Using animation and real world examples, this video explores the change in kinetic energy of particles with heating and cooling that produces expansion and contraction and change in density in matter. Students will observe and come to...

The period between WWI and WWII brought about major political changes in Italy, and yet it's fairly uncommon to discuss what actually went on in Benito Mussolini's fascist state during those years. Mussolini implemented policies and...

I think that nine out of ten people, if you ask them to picture a planet in their minds, will picture Saturn. Why? It's those rings! They are irresistible. Rings are to planets as peanut butter is to chocolate. The perfect complement....

In this video, students are taught about fractions and how to compare them using models and real-world examples. They learn that the denominator represents the number of equal parts, while the numerator represents the number of parts...

Inertia is the resistance to a change in motion. So an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by an unbalanced force.

We've learned about the stellar life cycle, so we know what happens to smaller stars like ours, and we know what happens to larger stars that become neutron stars and black holes. But what are the limits on either side? How small can a...

In this video, I go over tips on how to print ABS on an open printer and avoid warping or delamination.

Landforms part 7/9: The video provides an overview of the different types of water features found on Earth. It highlights the differences between oceans and lakes, including the fact that oceans are much larger and contain saltwater...

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...

In this video, students will learn about fractions and how to divide things into equal parts. They will learn how to write fractions using numbers and how to compare fractions to see which are larger or smaller. The video also emphasizes...

Fractions and mixed numbers.

In this video, the teacher explains how to measure objects using smaller, equally sized objects as units of length. By comparing the size of different objects like crayons, paper clips, and blocks, students learn how to determine the...

In this lesson, students will learn how to solve equations with variables on both sides by using inverse operations to collect like terms. They will understand the concept of combining like terms and isolating the variable to find the...

KS4 maths: A local dance school has a problem - it wants to enlarge the logo on their t-shirts. Dave heads off with tutu and ruler in hand to see if he can help. Dave has made two pieces of cake for himself and Fran, but cannot work out...

In this lesson, students will learn how to determine if two triangles are similar by checking for two corresponding congruent angles using a rotation and a dilation. They will understand that a dilation changes the size of an object...

In this lesson, students will learn how to create and graph exponential relationships by using a table of values. They will explore the concept of exponential growth and decay, and understand how to translate it into an equation.

When numbers don't tell the full story

Michael Goodisman is digging up the dirt on yellow jackets' peculiar sex lives by studying their nests, behavior, and genetic make-up. With support from the National Science Foundation, he is getting a better understanding of what drives...
