Traffic Light Detection

When you pull up to the intersection to turn onto my street, the traffic light is able to detect that my car has pulled up. Have you ever wondered how this is possible? I thought I'd explore more into this capability. The most common method is the use of an inductive loop which is a simple coil of wire within the surface of the road. https://auto.howstuffworks.com/car-driving-safety/safety-regulatory-devices/question234.htm This website gives a great example of how this process works.

Solar Street Lights

Solar street lights are becoming increasingly popular as a green alternative because they are a better value for their cost, have lower maintenance, and easier installation. But have you ever wondered how these technological advancements function? What powers it and how does it turn on at night? I decided to look into this and examine the circuits behind the lighting of a street lamp.

Have you ever seen a Galileo Thermometer? They are a pretty cool way of telling what the temperature is and it also serves as a cool decoration for your home. The thermometer has little glass bubbles with different color liquid inside of them. Each little bubble has a tag on them with a different reading of the temperature. You read a Galileo thermometer by reading the tag on the lowest bubble that is still floating. The way the thermometer works to change to different temperatures involves a bi

Vortexes and Mushroom Clouds

While doing some exploring on the internet, I stumbled across this video that does a pretty decent job of explaining a crazy pool vortex that forms when you push a plate through pool water. The woman in the video lists some examples of vortexes which include water going down a drain, hurricanes, tornadoes, and air going over a plane. In the example with the plate, the difference in velocity between the water moving with the plate and the stationary water next to it causes a shear force and makes

A Review and Conclusion

This year, I really pushed myself with new challenges that were difficult, but also very rewarding. I took on the challenge of a flipped classroom and learned a new way to be a student that will help prepare me for college. While at times it was a struggle to keep up, this course kept helped me prepare for college by forcing me to work on my time management skills. I think that I have a lot more of improvement to do on this, but I have come a long way from the beginning of the year. I think befo
