Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Swimming pools are no fun without water. For a pool in the shape of a trapezoidal prism, scholars first calculate the amount of water needed to fill the pool. They use experimental data on water flow to determine whether to haul water...

The area is essential to volume. As part of the review for the General Certificate of Secondary Education math assessment, a helpful video covers how to find the volume of several common 3-D figures. Pupils use the general volume formula...

The formula works no matter the shape of the base. A short video shows how to find the volume of a prism when the base is a composite shape created by rectangles. Handouts provide the class members opportunities to practice the skill and...

Not all prisms are cubes. A short video introduces the definition of a prism and uses that definition to create a general volume formula. Worksheets provide pupils several opportunities to practice finding the volume of a wide variety of...

Turn up the volume. After identifying the three dimensions of a prism, the presenter gives the formula for finding its volume. Using the formula, the video shows pupils how to find the volume of a rectangular prism and a cube. Classmates...

Calculate one hypotenuse then repeat. The resource provides a variety of ways for finding the length of the diagonal in a prism. Using the Pythagorean Theorem, pupils find a variety of distances in 3-D figures. The distances range from...

Don't let your classes get stuck on area calculations—grab their attention with an inquiry-based lesson! Scholars must develop a plan to determine how may sticky notes it takes to cover the surface of a door. They decide on the...

Who knew there were so many parts to a geometric solid?! Well, you probably did, and your pupils will, too, after watching a video lesson on three-dimensional figures. Instruction includes a description of the parts of solids, naming...

That would make a lot of cans! Learners analyze a photo of a truckload of aluminum to determine its value. The provided information includes the weight of a smaller block and the dimensions of the larger block. It's up to your pupils to...

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

Set the bases of a conversation on prisms. The segment of a playlist on geometry introduces prisms and their parts. After visualizing prisms, the video discusses how to find the surface area and volume of prisms.

Slice up solids. A portion of a geometry playlist introduces two conventional ways to visualize 3-D figures in 2-D. The resource defines cross-sections and nets and provides examples of both.

Scholars see cross sections come to life using an app to investigate cross sections of three-dimensional solids. They look at prisms, pyramids, cylinders, cones, and double cones.

There's no need to mention Cavalieri's principle obliquely. Individuals investigate the relationships between the volumes of right and oblique three-dimensional solids. Application of Cavalieri's principle helps them calculate volumes of...

Show your class how to model tents using geometry. Provided with pictures of different types of tents, pupils determine a geometric shape they could use to model them. They then use a variety of prisms and pyramids to model the tents.

How can you better explain the standards? A collection of resources gives teachers the resources needed to teach topics within the eighth grade curriculum. Lessons provide engaging activities to use within the classroom. 

Ever made solar s'mores? Or recreated the solar system using peanuts? Astronomers young and old investigate all things solar using a variety of activities. Explore how the sun works, types of light it emits, and methods of charting the...

Take a look at a prism after slicing and dicing it. Given a rectangular prism with all three dimensions, pupils draw the horizontal and vertical cross-sections and provide their dimensions. They also determine the dimensions of a...

Fascinate young life scientists by showing them how their brain learns. By using prism goggles while attempting to toss bean bags at a target, lab partners change their outlook on the world around them, producing amusing results....
