Tech post #3

It is the third week of tech. Yesterday we learned about atoms. We talked about how space has no sound and if you screamed no one would hear you. There is no sound because there is no oxygen. We also talked about how eyes have cones and rods. Rods help you see in low light and rods help with the color you see. We talked about lasers and how class 3 and class 4 could blind you if you stare at the laser. Class one and two are safer. Tech is fun and I am excited to continue the quarter!
