Why Do We Have Blind Spots?

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,...

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...

Students determine their eye's blind spot. In this biology instructional activity, students explain what causes this visual deficiency. They give real life applications of this concept.

Electron dot diagrams seem simple, but does bonding complicate the notation? The video explains how to draw dot and cross diagrams when bonding exists. It describes both covalent and ionic bonding and the different ways of depicting...

Pupils read a description of a physical situation and select the free-body diagram that best matches. As part of a series on applying Newton's Laws of Motion, scholars reinforce their skills applying forces and considering their relative...

In this service-learning engineering project, students follow the steps of the engineering design process to design a hearing testing device. More specifically, they design a prototype machine that can be used to test the peripheral...

Students gain a conceptual comprehension of the functioning of the Human Eye in relation to optics and optical vision correction. They explore optics with light sources and various lenses, relating these to visual acuity, accommodation,...

Scholars work through three activities building motion diagrams as part of a series exploring dimensional kinematics. Each activity has six descriptions requiring application of velocity vectors, acceleration vectors, and challenge...

Most pupils learn quickly how to apply Newton's Second Law equation to calculate net force. However, many struggle to determine net force before calculating the value of an unknown force from a force diagram. As part of a larger series...

Scientists use many different kinematic representations of motion. Review each of them with the help of an engaging interactive that is part of a larger series on Newton's laws of motion. The resource provides three levels of challenge...
