Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...

After training, pigeons can recognize correctly spelled words among misspelled words. In addition, they can use number sense to count, memorize thousands of pictures, and use navigational aids humans don't understand. As part of a larger...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Your eyes each work independently, so how do we only see one image? The quick hands-on experiment encourages young scientists to test their blind spots on each eye individually. After learning where the blind spot is and why it exists,...

Give pupils a magnifier, a mirror, and a flashlight so that they can examine their own pupils. As they shine a light on their eyes, the light is shone on how this structure dilates and contracts to control how much is allowed into the...

Visionaries create images out of dots to demonstrate the eye-brain connection. Through this activity, they learn that the brain interprets data collected by the eye into recognizable information. Search online for "Jacques Cousteau in...

A small card with a dot and an X is held at arm's length and used to show youngsters where their blind spot is. This illuminating little activity is a compact addition to your lesson on the structure of the eye as it explains the part of...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

You might find this video a little silly-ary (ciliary, as in, ciliary muscle). Giant, hat-wearing eyeballs with legs walk around as Chloe and the Nurb discuss different features of this light-collecting organ. Get your class focusing on...

Donde es la nariz? Distribute a copy of this picture to all of your young Spanish learners to introduce the Spanish words for eyes, nose, and mouth. They cut and paste the images over the words where they belong. Then, to finish, they...

This video about a delicate, often controversial topic, does not argue for one area or another, but does talk about the random process versus design of an involved organ. The lecturer talks freely about how infinite complexity such as...

A student is taking her first exam in Japanese. What are some factors that could affect her success? Learners consider the question, as well as examine a study on vision and feedback using authentic College Board materials. 

Deciding where to go to college is a tough choice, but psychology helps shed some light on how people make up their minds. Learners consider factors such as ethnocentrism and crystallized intelligence using an exam from College Board. A...

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...

Eyeballs or cameras—which have the best functions? The video presentations compare the important functions of the eyeball and the camera. As technology changes, cameras become more impressive, but the eyeball still out-functions the...

Why can some organisms detect polarized light, but others can't? Scholars observe as the narrator constructs, demonstrates, and explains a simple polarimeter during a video from a larger playlist covering physics. Concepts include how...

What would you do if you could be invisible? It may not be as much of a daydream as you think! Discover the possibility of invisibility through a video from the ACS's Reactions playlist. The resource covers current invisibility...

Does a carrot a day keep the eye doctor away? Junior nutritionists tackle the legend of better eyesight through carrot consumption using a video from the American Chemical Society's Reactions playlist. The narrator exposes the origins of...

Convince your pupils a purple ball is really red, blue, and green with a YouTube video lesson that demonstrates the persistence of vision using a simple ball. When the ball is in one place, it appears purple but when the instructor spins...

Legolas counts the number of riders on steeds at a distance of five leagues away, including knowing their colors and height, in J.R.R. Tolkien's Lord of the Rings. A video researches this possibility by starting with the assumption that...

What should you do if you are studying for a test and your glasses break? The video introduces an easy way to instantly improve your vision. It discusses why it works and the physics behind vision, lenses, and focus.

Our bodies have some amazing capabilities, but there are some limitations. Explore the limitations of the human eye through the eighth lab activity in a series of 12 biology lessons. Individuals measure their own peripheral vision and...

Why would someone need contact lenses that offer UV protection? With a 28-page packet full of instruction and worksheets, young scholars discuss solar radiation and its potential harm to eyes. They make snow goggles similar to ones...

Humans can only see visible light, but some insects can see ultraviolet light. Through a simulation, pupils explore how we see colors using one bulb. It moves on to demonstrate how we see colors by mixing three different bulbs (red,...
