Thursday March 24

We started class by going over homework. We talked about the scientific names for the first day of the seasons. Winter's is the Winter Solstice. The winter solstice is when there is the shortest day of the year. The Summer's fist day is called the Summer Solstice. This is the longest day of the year. The first day of Fall is the Autimanal Equinox and the Spring's is the Vernal Equinox. The Equinoxs are the days when there is an equal amount of night and day.
After that we did an experiment where Colleen held a laser still and Mr.Finley turned the globe around. Before the earth was turned arouned the dot was on the Tropic of Cancer. When it was turned around it was on the Tropic of Capricorn because of the tilt. This showed where the sun is in the Winter and Summer. We also comncluded that there are no seasons in between the Tropics and even if there are there very mild.
After that we did an experiment with a cicle and a bowling ball where we removed a part of the circle and the bowling ball went straight which showed that if the sun disapeared the planets would just go staight.
