#### Determining Densities

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Lesson Planet

#### Floaters and Sinkers

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Lesson Planet

#### Composite Solids: Lesson

Combine the formulas to arrive at one volume. Using the formulas for different solids, the video introduces finding the volume of composite solids. The portion of an extensive playlist on geometry works a couple of problems, one with an...

Lesson Planet

#### Spheres: Lesson

Unwrap the surface of a sphere. A section of an extensive geometry playlist introduces the formulas for finding the surface area and volume of a sphere. The video includes a clip of how the surface area formula is developed by unwrapping...

Lesson Planet

#### Pyramids: Lesson

Pyramids: they're not just in Egypt! The segment of a large geometry playlist introduces the formulas to find the volumes and surface areas of regular pyramids. Using the formulas, the presentation works several examples to ensure your...

Lesson Planet

#### Cones: Lesson

Just how much ice cream will the cone hold? The video provides the formulas to find the surface area and the volume of cones. Using example problems, the section of a geometry playlist shows how to use the formulas to find the surface...

Lesson Planet

#### Cylinders: Lesson

The solid is the same as a prism ... well, almost. The presentation makes connections between finding the volume and surface area of cylinders to prisms. Using the newly derived formulas, the portion of a large geometry playlist...

#### Raspberry Chocolate Heart Cake

Have you ever finished a piece of cake and wished you had more? Solve this common dilemma with math! A straightforward worksheet prompts middle schoolers to use the given dimensions of a heart-shaped cake when planning to bake two larger...

Lesson Planet

#### Water Bottle Unit

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

Lesson Planet

#### Cape Florida Lighthouse: Lore and Calculations

Analyze the Cape Florida Lighthouse with a little mathematics! Combining different aspects of cones, pupils calculate the volume of the building materials needed to build the lighthouse and then the surface area of the outside. Because...

Lesson Planet

#### Sports Drinks

Drink it all in. By applying the volume formulas, learners determine the amount of a sports drink that fits into a cylindrical cooler. They compare this volume to that of 24 individual containers.

Lesson Planet

#### Snow Cones

Snow cones: more volume with cones or cups? Individuals find the volume of a cone and a cylindrical cup from diagrams. They compare the volumes to answer the opening question.

Lesson Planet

#### Softball Complex

Before we can take you out to the ball game, there needs to be a field on which to play. Future mathematicians design a softball complex given several criteria. They then create a scale drawing of this complex.

Lesson Planet

#### Volume of Pyramids: Fluctuating Height

The height of a pyramid may change, but the usefulness of the interactive will not. Learners drag the apex of a pyramid to change its height. They then answer a set of challenge questions designed to investigate how changing the...

Lesson Planet

#### Linear Equations: Deep Dish Pizza

Explore the volume of solids with a real-life connection. Learners calculate the volume of a deep-dish slice of pizza to determine its price. They model the slice as a part of a cylinder and create a formula for calculating the cost.
