We started our 6 week unit studying the human eye. Each week we learned about a new feature of the eye. So far we have learned about the iris, the pupil, the lens, muscle, retina and optic nerve.
Then we asked, Which light sources would you not want to be without?
We considered many objects that give off light but life without the sun we could not quite imagine! While all objects reflect light we were interested in identifying in the school objects that are light sources.
How does light travel?
Mirrors helped us answer this question. We learned that light travels in straight lines. We learned that a mirror reverses what we see. We learned that depending on how we set up mirrors we can change how many bears were in the reflection! We could even make the bear disappear!
What is the difference between translucent, opaque and transparent materials?
We will enjoy experimenting with these materials and using what we learn to create shadow puppets.
Finally we will observe how white light is made up of different colors. Now, how will we do that?
