This video will show students how to find the formula to calculate volume for a cylinder.

This video will show students how to find the formula to calculate volume for a cone.

This video will show students how to find the formula to calculate volume for a sphere.

Show students how creating a scatter plot can show a relationship between two different sets of data.

This video lesson reviews how to rewrite expressions using the properties of operations: the commutative property of addition, the commutative property of multiplication, the associative property of addition, the associative property of multiplication, the identity property of addition, and the identity property of multiplication. This video provides sample problems for your class to solve as you review each property.

How many bricks does Rosa need to make a border around her garden? This video lesson models how students can use what they know about shapes to solve a problem. Students will find the perimeter of the garden by adding the length of all four sides of the square.

Did you know most rain in the United States starts as snow? This video explains how water changes state during precipitation, resulting in snow, sleet, hail, or rain.

Explore force, friction, and the movement of objects. This video demonstrates how a student in a wheelchair uses force throughout the day to move objects. Students will learn about contact forces, balanced forces, and unbalanced forces.

Why does the shape of the moon appear to change? This science animation explains the phases of the moon.

Plants grow in different climates. Use this video to compare the growth of the water lily, cactus, orange tree, and morning glory. They are alike and different in many ways.

This video introduces students to two living things: plants and animals. See how living things grow, change, or move on their own.

This video demonstrates how water changes physical state from a solid to a liquid to a gas.

This video demonstrates how magnets attract some metal objects.

Watch this video to learn about food chains. A food chain shows how energy moves from one living thing to another.

Watch this video to learn about light and heat, two forms of energy. Energy makes things move or change.

This video teaches students to multiply two mixed numbers by changing them to improper fractions, then how to multiply and simplify.

Students can locate irrational numbers approximately on a number line diagram, and estimate the value of expressions.

This video defines what a transformation is, as well as rigid motion and image when identifying a figure.

This video shows students an example of how to rotate a figure correctly within a plane across an axis.

Help students understand the distributive property with subtraction using figures.

Help students find a unit rate by dividing the fraction, which is the same as multiplying by its reciprocal.

Show students using this video that they can use the signs of an integer to determine if the product will be negative or positive.

This video shows students the inverse relationship between multiplication and division. They will also learn to use the inverse to check their answers.

This animation demonstrates Newton's first law of motion, also known as the law of inertia.
