Week of 1/11 - 1/15

This week was probably one the busiest and knowledge learning week ever! Well to take up two of the days in the week, we took the test for the Biology Placement. The first day we had about 40 questions of muliple choice and for the last day we took a essay. I had ade many careless mistakes on the questions but for the essay I think I nailed. I'm not that interested in Honors next year because first I want to see what High School intells for me. The other three days of the week we continued on learning about the moon but we switched gears from learning about phases to tides of the moon. There are two tides the Neap tide, Spring Tide. The tides and the moons rotation creates the high and low tides at the beach. The neap tide means moderate or less extreme tides. These are the low tides but then the spring tides are very high tides or very low tides. So there the huge ones or the calm flat water. In other words the neap is like the average low/high tide. And the spring is either those really high ones or the really low ones.

We also learned about the tilts of the earth and how that creates the seasons. If the earth is tilted closer to the sun then the season is winter and if its farther the season is summer. Many people and I would think that if the sun is closer to the sun its summer because its warmer but apperantly thats not true. The earth being tilted causes one hemphirse to be pointed to the sun and the other should be pointed away from the sun. Also sun light is more consentrated based on tilt and position. And based on position in revolution the tilt could change. All of these aspects could change whether is winter or summer.

The real world application for this lesson could be just looking at the moon you can not just tell the phase but also the tide and then you can know if its summer or winter.
