New ReviewHere's a short video that hits all the high notes! Young scientists observe as amazing patterns appear in sand during a short demonstration. In addition to art and music, the resource explains standing waves, nodes, and how a 3-D model...

New ReviewHow can something as vast as the universe also be flat? Go beyond the Big Bang Theory using a video from an expansive physics playlist. Topics include the expansion and inflation of the universe, why opposite sides of the universe are...

New ReviewWant to see your class flip out over a simple question? Blow their minds and challenge young physicists using a video from an engaging physics playlist. The narrator demonstrates how mirrors show only what they are presented and...

New ReviewCombine 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...

New ReviewSlice 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.

New ReviewBlow up a solid by a scale factor. A section of a larger playlist on basic geometry introduces the ratios of the surface areas and volumes of similar solids. Using the ratios, the video works several examples involving similar figures.

New ReviewImagine a poly-what? With the aid of pictures, the segment of an extensive geometry playlist introduces specific polyhedrons and their parts. The presentation uses Euler's Theorem to explain the relationship between the number of faces,...

Does the shape of a hay bale affect profits? A practical instructional activity asks scholars to calculate the volume of both square and round bales of hay. They compare their results with hay prices to determine value.

Salt and sugar look the same but taste very different! Scholars learn that while isometric drawings look the same, it doesn't mean they are the same. They begin by determining if two constructions are equivalent or not. Then, they learn...

What we call 3-D is only a good substitute. Part of a larger playlist on physics, an interesting video demonstrates different attempts at three-dimensional perception. The final example shows a true 3-D projection in the form of a...

Time for a change in perspective. A video lesson explores the progression from 2-D to 3-D images. The instructor from the physics playlist first explains the workings of a traditional camera and compares that to the creation of a 3-D...

Scholars examine isometric drawings that seem to be impossible as part of the final lesson in a six-part series. They use the isometric drawing tool to build figures and observe them and then investigate one way Escher created these...

Can you have an object with a larger volume than surface area? Young mathematicians explore finding the volume and surface area of three-dimensional figures. Using an isometric drawing tool, they discover the volume and surface area of...

Mat plans combine the aerial view with the number of levels at each point. Middle schoolers compare an isometric drawing with a mat plan as part of the fourth lesson in a six-part series. They practice making their own mat plans and use...

Visual reasoning plays a key role in architecture, engineering, and video game design. Scholars use visual reasoning to translate isometric drawings into front-right-top views during the third instructional activity in a six-part series....

Here is a lesson plan that is a diamond in the rough! Groups work to find all the possible nets of jewelry box in the shape of a cube. Using grid paper, they draw out their nets and defend them to the rest of the class.

Think of current acoustic levitator technology as a hover board for tiny things! Introduce young physicists to this emerging gadget using a video from an informative playlist touching on physics topics. Viewers watch as Physics Girl and...

Things are really shaping up! Provide young chemists with polyatomic ion practice using an interesting interactive. Individuals complete puzzles focused on molecular geometry and complex ions.

We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

Finally, an easy-to-make volcano model: no baking soda and vinegar required! Junior geologists construct a volcano in 3-D, then use it to answer questions about the processes and timescale of igneous rock formation. The activity includes...

How do they create those 3-D views on a 2-D surface? The video presents the history of the art of using anamorphic perspective. A review of perspective drawing provides background knowledge to the class. Pupils see different methods...

Graphics can make or break a video or computer game. A thorough installment of the Crash Course Computer Science series describes different types of graphics projections, including orthographic projections and perspective projections. It...

Who cut the cheese? Given a drawing of a wedge of cheese, pupils determine the 2-D figure cross-sections. They draw and describe the cross-sections created by making slices perpendicular and parallel to the base.

If you draw it, they will view it. The resource allows pupils to draw 3-D figures using faces, edges, or cubes. Learners inspect their figures while rotating, decomposing, and viewing it in two and three dimensions.
