revOlutIONS aND oUR EArTh

MONDAY- HOOOOROAAAAYYYY MLK DAYY!! NOOOO SCHOOL!! NOOOOO SCIENCE!!!!!.....i mean boo

TUESDAYYYY- now werwe back at the Npms, fun 3 day weekend!
ok so today, tuesday not monday!,we discussed why the earth has seasons, a BIT of a continuation from last week. so we did an experament with a flash light where we made the OpEN door INDIREct and a closed one EDIREct. the flashlight was the sun. and the door was the earth. there is a 23.5 degree tilt on the earth. the tilt on the earth makes the sin's light direct and indirect. when indirect it is cooler, and when direct it is wawrmer.

WeDNESDAy- yayy not TUeSDAY
ok so TODAY we went over SOLTICCES and EQUINOXES. a soltice casuses the longest and shortest days and the equinoxes is when the days and nights are equal. ex- 12hrs day and 12 hrs night.

THURsDay- yayy not WEDNESDAY
ok so today we went over a lot of stuff too. we had a quiz on equinoxes and soltices and whatever the heck we leanred! we also did a simulation during class with the earth and sun. we did this because we were learing about earth and moon revolutions and orbits.

FRIDYYy!- YAYYY (this is today!!!)
ok so today ( and this time thats ACTUALLY today!)
we made a list of things that u have to do in order to orbit. as follows
+2 massive objects
+object has some sort of initial velocity (but it has to be juust right)
+moving too fast, it will just "flyu away"
+moving too slow, crash into earth haha
+distance away makes a difference.
+and mroe!

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.

tHURSdaY AND WeDnESDAY
we had that honors biolilogy thing......

FRIDAAYY
we went over seasons agaibn!

MOOoON

This week in science we started a new unit. i am so happy that theres nooo more kinimatics and dynamics!!! yayy!!!!

ok so this new unit is moon stuff.

on the first day (MONDAY) we went on a website and we looked at moon simulatioins. we made observations about it. we had to make like ten observations in our notebook. and then we shared them with the class. in the class we disscussed about moon patterns and we got an introduction to the moonphases.

on tuesday, (SECOND DAYY]] we did moon phase stuff. we tried to memorize them...

on wednesday, thursday, we did a lab in the website.

on friday we went over it.
