    Bundle Description

    Twenty four labs to study pinholes, concave and convex lenses, concave and convex mirrors, the human eye, and how telescopes are designed. Most of these labs require no setup and could be used in centers or stations. The directions are written directly to the students so you don't have to introduce them.

    Six of the labs includes a one-page reading that can be used as a read aloud or student reading or teacher read-aloud. Reading includes questions and answers. All labs include cards for Claim, Evidence, and Reasoning (CER) that can be used in a variety of ways. Each of the labs is complete in itself and builds upon concepts taught in the other labs.

    Use this to learn and reinforce answers to questions such as:

    • What happens when you put a pinhole in front of a bright scene?
    • How can you set up a pinhole to show a scene?
    • How does the size of a pinhole affect the image it makes?
    • How does the shape of a pinhole affect the image it makes?
    • How does the distance of a pinhole from a screen affect the image it makes?
    • How do objects look when viewed through a convex lens?
    • How do objects appear to change according to the position of the convex lens?
    • When does an image appear upright when viewed through a convex lens?
    • How do images appear different when viewed through convex vs. concave lenses?
    • What type of lens can flip an image vertically or horizontally?
    • What types of lenses are used in telescopes and why?
    • How does the image viewed in a concave mirror change depending on your location?
    • What does an image look like when an object is held near a concave mirror?
    • How are concave mirrors used in everyday life?
    • How do curved mirrors affect light?
    • What type of mirror can make enlarged images?
    • How do curved mirrors compare to curved lenses?
    • What structures can you identify in a friend’s eyes?
    • What is the purpose of a pupil?
    • What structure(s) in your eye focus light?
    • How does your eye react to changing light?
    • What is your blind spot and how can you demonstrate it?
    • How does your eye focus on different objects?

    Once students try this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions. 

    Concepts Addressed

    • Light coming from objects can be projected onto a screen.
    • A pinhole will cast an image of whatever is behind it.
    • Lamps radiate or give off light.
    • The size of a pinhole doesn’t affect the size of the image it makes.
    • The shape of a pinhole affects the clarity and brightness but not the shape of the image it makes.
    • The farther a pinhole is from a screen, the larger the image it creates.
    • When a convex lens is held near an object the image is always upright.
    • Convex lenses converge or focus light.
    • The image you see through a convex lens depends on its location relative to its focal point.
    • Both convex and concave lenses can change the size of an image.
    • Convex lenses can flip the image vertically and horizontally.
    • Concave lenses don’t flip images.
    • How does the image viewed in a concave mirror change depending on your location?
    • What does an image look like when an object is held near a concave mirror?
    • How are concave mirrors used in everyday life?
    • Concave and convex mirrors will make distinctly different types of images.
    • Concave lenses behave like convex mirrors.
    • Convex lenses behave like concave mirrors.
    • Your pupil is formed by your iris. It contracts and expands to let in light.
    • The sclera encases and protects your eye.
    • The optic nerve exits from the back of the eye and connects to the brain.
    • Light stimulates a reflex to contract muscles in the eye.
    • Our retinas have a blind spot where there are no light receptors.
    • Muscles in the eye can stretch and change its lens’ shape.
