This is the first lesson in a series of lessons listed below. The first lesson starts out with students exploring how many shapes they can see on different pieces of paper at various locations around their classroom when the lights are turned off.
Lessons in the unit include:
L1: What can we see in our room?
L2: How can I block the light that’s coming into our room through the windows?
L3: Which materials will block the light best (to help us make our room as dark as possible)?
L4: What do we see when we look into a place where all the outside light is blocked from getting in?
L5: How does letting light into the box affect what we can see inside it (with the ipad/smart phone)?
L6: What are some light sources that are small enough and safe enough to bring into our box?
L7: What would we be able to see in the box (or any closed up place, like a cave covered up at the opening) if we brought a light source into it?
L8: Where else do people use materials to block out the light?
L9: Will all materials create a shadow?
L10 Where else in the world do we see light sources, light going through different materials, and different materials making shadows
L11(a-c) How can we use light to communicate without making any noise? L11(d-f) How can we evaluate our designs and use the results of everyone’s tests to improve our own design?
L12 What materials could we use to redirect light around a corner to communicate with someone in a different room, or in a different hallway, or on a different floor, without making a sound?
