Knowing how materials interact with light is important...especially when they'll be needed to solve a problem!
First graders are using their knowledge of how light interacts with materials to get a Lego man to illuminate. Sounds easy...except Lego man is behind a wall and they can't move the light source! Using a set of mirrors and changing their angles (or the way they are tilted), students are using the engineering design process to reach their intended goal. When one plan doesn't work, they improve their plan to include another idea!
Awesome work first graders!
