BLUE SKY LAB REPORT Purpose: The purpose of this lab report is to see whether or not we could recreate the color of the sky with milk added to water and a flash light. In class we learned about what makes the sky blue and how it becomes blue due to our eyes and white light. Hypothesis: The sky is blue because blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. I do think you can recreate the color of the sky in a glass of milk with a little water added to it because the sky and the milk are both originally white. The flash light gives off white light, white light has all the colors of the rainbow (Red, orange, yellow, green, blue, and violet.) The light will reflect through a prism and scatter all its color, so the color blue will reflect to our eyes and the other colors will be absorbed by the milk. Materials: Water, Milk, Cylinder, and a flash light. Procedure: 1. The first step we did in our experiment is we took school milk and added it to a little bit of water in a cylinder. 2. Next, we took a flash light and flashed it upward but couldn’t really see any colors. 3. Then, we flashed it forward through the cylinder and saw a little red but little to less of any colors 4. We then used store bought milk with a little water to see if there was a difference in school milk and store bought milk. 5. With the store bought milk we flashed the flash light above the cylinder and could see blue and a little red/orange sunset in the bottom of the blue. 6. Finally, after setting the flash light in different positions with the store bought milk it showed the same colors no matter what position with the color blue and a little sunset under it with the color red/orange. • Blue sky When we used the store bought milk you could see the
