Mrs. Brinza's given the first graders a challenge...try to answer a friend's question WITHOUT TALKING!

Using a code, first graders are showing how they can communicate by using light.  Since light interacts with materials differently, light can send a message in many different ways.  Light can flash, stay on, turn off, and even create different types of shadows based on it's relative position to an object or the tyo of material the object is made from.  Knowing all these things will come in handy as first graders create a "LIGHT CODE."  

For example, flashing a light might represent "YES."  Turning the flashlight off might represent "NO."

Using this code, can you learn a little bit more about Mrs. Brinza?

First graders are working on drawing models.  Modeling is an important practice of an engineer's work. Using various materials, first graders are drawing and explaining what happens when those materials are placed in front of a flashlight.  They are looking for evidence to support the reasoning in their models.
