this week in science we started to learn about what solstice and equinoxs are. i found out that a solstice is A solstice is an astronomical event that happens twice each year, when the tilt of the Earth's axis is most inclined toward or away from the Sun. i got this from wikipedia. and the equinox is An equinox occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the Sun being vertically above a point on the Equator which i also got from wikipedia. Then later in the week we looked at this really cool earth to sun orbit simulator, i thought it was kinda like a game because i wanted to see if i can get the orbit perfect around the earth. but we had to do 20 trials of placing the earht from the sun and testing the speed we would put it at. In the begging i could not get it to orbit but after a while and seeing what speeds and distances worked close i got it.

this week in science we went over a lot of different and new things. the first objective that fin gave us was to look at this moon simulator and make different observations. i found out a lot of cool things about the moon the way it revlovels and the different illmultations it has. there are 8 different phases of the moon. also i learned what the differnce is between wanning and waxing. wanning is when it is in a phase but over time the ammount of moon you can see will decrease. but when it is waxing it is the opposit you will be able to see more of the moon. we were going over this through out the week but at the end of the week we were starting to go over what the moon can do with the tides. our homewoork was to reserach what the moon does with the tides, so i am going to stop blogging and do my homework.
