Does the moon change size? It sure looks like it! Two optical illusions are suggested as an explanation: Ebbinghaus and Ponzo. However, there are problems with both of these. Convergence micropsia may answer the question, but many...

Students draw an optical illusion. For this optical illusion lesson, students create the optical illusion vase. Students draw a profile and repeat the drawing in reverse creating the vase image.

In this recognizing equivalent fractions worksheet, students use a color code box of fractions with color names, determine and color the equivalent fractions on figures of optical illusions, and answer word problem questions. Students...

You could call this five presentations rolled into one resource! The first topic of concern is the characteristics of electromagnetic waves.The electromagnetic spectrum is examined next, followed by the behavior of light. Several slides...

Students investigate the concept of an optical illusion and how they are used. They conduct an information search of how the eye works. The information is used in order to set the context upon the creation of a personal optical illusion.

What the eye perceives can be deceiving. Learners can make a spinner that creates an optical illusion by merging two images. They can experiment with ways to make them in different shapes and styles to get varied results.

Here is a great science lesson. It extends the concept of vision into the area of optical illusions, perspective, and tessellation. This well-designed plan has tons of great activities, utilizes interesting video, and should lead to a...

Students examine and create a tool that enables them to explore the scientific principle the Moire Effect. Using markers, paper, and scissors, they create an optical illusion that involves superimposing a grid of lines over another...

Learners explore the composition of 3-D optical illusions by analyzing and combining 2-D visual elements graphically in banner form. They dissect the designs to undercover the mathematical elements of the illusion.

The focus of a playlist on the history of film shifts from the development of early film technology to techniques used by filmmakers like Georges Melies. Melies, a former magician, used dazzling illusions and tricky editing to create...

Students explore illusions by drawing and viewing images in class. In this art perspective lesson, students analyze a skeleton outline drawing which demonstrates the ability to draw in a two point perspective. Students utilize the...

Learners create an optical illusion. In this optical illusions lesson, students sketch a monster's face to create the optical illusion of a vase in the positive space. Learners create an original piece of art.

What have our eyes and brains evolved to see? Discover the way our photo receptors and brains assemble visual information into the three-dimensional world we see around us.

Students are given a mnemonic device to review the light spectrum as it relates to the different components of refracted light. In this components of light lesson plan, students read Light Magic and review the properties of light....

Op art is fun to look at, and it's fun to make. Kids learn about the origins of op art and the op art master, M.C. Escher. They view simple to complex examples of op art to see how it works and then create an optical piece of their own....
