Students spent the day working on the projects. Here are the projects that are being done...
- Rocket Recovery
- Why Aerobie Flying Wings Fly Better Than a Frisbee
- Chemistry of ice Cream Making
- How the Surface of an Inclined Plane Affects How Far an Object Can Travel
- Determining of Iodide Content of Salt
- Pinocchio's Arm (objective - to detect changes in the brain when a person is telling the truth and when a person is lying.)
The X-15 went straight up for about 200 feet, then immediately started flying towards the east (we were in the back of the school). We followed it until the parachute was supposed to deploy, but we couldn't see it. The group looked out front but couldn't find it. I hope it landed on the roof! Science is wonderful, but things don't always work out as we hope!
We finished the last light lab activities. These were...
- How Does Primary Colored Light Affect What We See? Students had four sheets of paper (red, blue, green, and white) and three flashlights (covered with red, green, and blue filters). Lights were turned off and students shined each color flashlight (along with one that had white light - the filter removed) on each color paper. Students then identified the color they actually saw.
- Adding Colors. Using the three flashlights with filters, students shined them on white light. They first shined each individually. Next, they combined two of the colors (red w/green; green w/blue; red w/blue). They identified the colors they saw with those light combinations. Finally, all three colors of light were combined and students should have seen white (or almost white, I hope!) light.
- Paddle Colors. Students received six color paddles (red, orange, yellow, green, blue, and violet). Students took two paddles (e.g., red and blue) and put them together. They shined the flashlight (no filter) through the paddles to see what color those two produces. They did that for all the combinations.
