Pupils examine the principles of visual acuity and how it pertains to sight.  For this measuring lesson students complete several activities on vision. 

Learners participate in a teacher-guided activity to teach about protein synthesis. Student roles include one person as the DNA molecule, another is a single stranded sequence of complementary mRNA.

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...

You will need an electric drill and some Velcro™ in order to have this activity available for your class. It is, however, an intriguing display of optical illusion. After watching a spinning disk (provided), viewers look at one of...

Put a new twist on your collection of optical illusion activities. Affix the linked printable spiral to a drill, record player, or some other rotating tool. Have learners stare at the spinning disk for only 15 seconds and then look away....

Learners use their teeth for more than just eating. The activity shows class members how to send sound through their teeth by using an electric motor connected to a radio to generate vibrations. Biting on the motor...

Students view various images designed to create a sense of disequilibrium in visual perception. They view the images, decide what they see in each, record their ideas, and write stories based upon their observations.

Students examine how depth perception works through a class experiment. They design and perform their own experiment that investigates visual illusions.

Pupils view various pictures designed to create a sense of disequilibrium in visual perception. They view the images, decide what they see in each, record their ideas, and write stories based upon these observations.

By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference. 

Take a real close look at your phone screen. What do you see? Here's an activity that provides guidance on how to look at a smart phone screen in order to see the pixels and to see how the phone creates colors and motion on the...

Students study how images they see are transmitted to the brain.  For this sight lesson students complete several activities that have to do with visual pathways and field defects. 

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...

Build an interest and appreciation for architecture in your young learners with this fun 10-lesson art unit. Engaging children in using their five senses, the class first observes the environment around them, paying...

Young scholars compare the process of protein synthesis in an analogy. They simulate the process of protein synthesis kinesthetically using index cards and write a paragraph to explain the process.
