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

The Physics Behind Curling

As I looked into other Olympic winter sports for my third edition of physics in winter, I thought I might explore the physics behind curling a little but more in depth. At first when you consider curling, you automatically think of friction and how that plays a large role in where the stones land during competition. I also thought about conservation of momentum because when the stones knock into one another, it is pretty clear to see that momentum is conserved when one block moving with some ini

Electric Motors

In class we learned about how electric motors work and we talked about a couple examples of things with electric motors such as your air conditioning. To review, moving charges in magnetic fields experience forces. When the charges move perpendicular to the magnetic field, they experience a force which is applied to the wire. With electric motors, moving charges are sent through a loop of wire which creates motion when you examine the forces acting on the wire. There are several everyday househo

Popcorn

Popcorn is probably my favorite snack ever. But how does a small hard kernel turn into this fluffy, buttery treat? Here is what I learned: Popcorn kernels have a hard shell on the outside, but on the inside there is moisture and starch. Thus when you put a bag of popcorn in the microwave, the kernels inside start to heat up and the moisture within the kernels turns into steam. The steam then tries to escape, but is blocked by the hard outer shell. The pressure that builds up from the s

Spinner Reflection

On Monday during physics class, we were asked to create a “top” that would spin for a long period of time. The materials we were given included two small paper plates, a pencil, six pennies, and tape. At the end of the lab experiment, we were asked to answer the following questions in a blog post: How did today's opening activity relate to the engineering design process? The engineering design process involves designing, building, and testing something. This relates to what we did in c
