Moon Moon Moon!!!!!!

OOHHHH MONDAYY!!!!
today we applied force diagrams to the earth sun moon relationship. we learned about tides and how they have to do with the moon! the moon affects tides because of thier gravitational pull, apparently its NOT the magical moon stuff. we learned about 2 force diagrams, and 2 different tide types. here they are!
Neap Tides- moderate or kess extreme tides
Spring Tides- very high high ties and very low low tides. tides are to thier extremes.
THATS A LoT OF STUFF FOr ONE SIMPLE MODAY!!

YAYY TUEsDAY
on tuesday we andswered some astronomy questions including WHy do we have seasons? this was a very good question. we spent a looooonnnngggg time thinking of hypothesis and we narrowed it down to these
1. tilt causes earth (one hemisphere) to be pointed/angled toword the sun, and one (hemispohere) away from the sun, causing warmer/ clolder wseasons. we have four but not nesesirly everyone does.
2. sunlight is more concentrated based on tilt and position.
TILT AND ROTAION DETERMIN SEASONS.
