Day 4

For our morning meeting, we went into a room, shut off the lights and closed the door, got used to the darkness, then covered one eye and walked around outside of the room. Then we went back to the room, made it dark again and uncovered the covered eye. One eye could see while the other eye looked like it was covered or blindfolded. Our "homework" was to figure out what was happening. Our eyes were adjusting to the light by making our pupil smaller, but in the dark the pupil grows so it can take in more light.
Today I finished my experiment with using ultrasound to find the depth of ice. I found that as we used bigger ice, we had to use lower frequency on the machine to be able to transmit through the whole cube. I also searched for ways to make snow. I enjoyed today because of the hands on experiences.
