Dear Mimmo,
This week you will learn about Planetary Orbits one of the questions will be why don't planets crash into the sun if the sun is pulling them in? One of the things you should think of is if your walking straight and someone pushes you you turn directions, and if that keeps happening then eventually you will turn into a full circle like an orbit.

What science ideas did you learn?
This week we learned about Solstice and Equinox. We learned that there was a winter solstice where we have the shortest day and there is a summer solstice where we have the longest day. The reason we have a summer solstice is that the we are tilted towards the sun so the sun takes he longest to travel across the sky. We have a winter solstice because we are tilted away from the sun so it takes the smallest amount of time for the sun to travel across the sky. We also learned why if the sun pulls the earth in then why doesn't it crash it to the sun. We learned the reason for this is that since the earth wants to go straight, but the sun is pulling it in the it makes a circle around the sun.
How did you learn these ideas?
We learned about the solstice because Fins asked us to look up the definition and then we made a picture to show the answer. We learned about the sun and the earth because we had to look at a simulator and we had to observe what happened in it finally we did a little lab and handed it.
Why is it important to learn this idea (What real world application is there)?
It is important to know that the Earth won't crash into the sun because if I didn't I might do something stupid because I would think I only had a few days left to live

What science ideas did you learn?
This week we learned a tiny bit more with tides, but very little. We mainly learned about why we have seasons. Many people these days don't really know why we have seasons, but I do. W learned that we have season because the earth tilts back and forth towards the sun so in the summer the sun is direct and in the winter the sun is indirect.
How did you learn these ideas?
We learned this idea because Fins asked us why we had seasons and made us look at a diagram of the earth rotating around the sun and we had to come up with hypothesises. Finally we put them all together and took out the incorrect ones.
Why is it important to know this idea (What real world application is there)?
It is important to know this because one day I could be on a game show with the million dollar question and it could be why do we have seasons. Then I could think back to 8th grade science and win the money.

What science ideas did you learn?
This week we learned a lot. We learned about the moon. We learned how the moon rotated and revolved around the sun. We also learned the 8 phases of the moon. We also learned how each phases is formed. Each is formed because the sun shines on part of the sun and that's what we see. Finally we started to learn how the moon effects the tides.
How did you learn these ideas?
We mainly learned these ideas by looking at s simulator. Finley told us to watch the simulator and to see how many things we can find out about the moon. After, we started to answer questions about the sun and the moon.
Why is it important to know this idea (What real world application is there)?
It is important to know this idea because one day I could be a fisherman. If I know how each phase effects the tides then I would know when is the best time to go fishing because the tides effect the fish. Then I would think back to 8th grade science I would catch more fish and make more money.

What science ideas did you learn?
This week we did a lot of the same stuff as we did last week. We did more force diagrams and motion diagrams. The many thing we really learned was that when two objects hit the forces are equal. For example when someone hits a golf ball with a club when they hit (lets say) they both put 50N on each other. The only reason the ball moves forward and the club doesn't move back is that the club is every.
How did you learn these ideas?
We learned this idea because Mr. Finley told us to draw a force diagram of a golf ball being hit by a golf club. When we drew it, we had to draw to separate diagrams because they were two different objects working on different things.
Why is it important to know this idea (What real world application is there)?
It is important to know this because one day I could be playing golf with Whoopi Goldberg and she might ask me to draw force diagrams for her hitting the ball. I would then think back to 8th grade science and draw a perfect one.

What science ideas did you learn?
This week we learned that the delta v arrow points the same direction as the unbalanced force. Other than this it was the same stuff as last week. We did more motion diagrams and force diagrams, but this week it was more with double force diagrams going horizontally and vertically.
How did you learn these ideas?
We learned that the delta v arrow goes the same direction as the unbalanced force because we had a class argument and then we identified the longer arrow to be the unbalanced force. Therefore the delta v arrow goes the same direction.
Why is this important to know (What real world application is there)?
It is important to know this because one day I could be a professional force and motion diagram drawer and I will have to know that the delta v arrow is the same direction as the unbalanced force> To know this I will have to think back to 8th grade science.

What science ideas did you learn?
This week we learned about force. We learned what forces do to objects. For example to hold a ball up you apply force up while the earth applies force down. Then we learned that the heavier the more force has to be applied to hold it up. We also learned when there is more earth force then the opposite force the object goes down, but if there is less earth force then the object will go up. We also learned how to create force diagrams. You make a dot to be your object and then you draw one arrow going up from the dot and one arrow going down from the dot. If the object doesn't move then your arrows are equal. If your object is going up then the upward arrow is longer. If the object is going down then the the arrow going downward is longer. We finally learned about force number sentences. For example (+10)+(-10)=0, this means the object isn't moving. If the object is going down the answer would be negative. If the answer is going up the answer would be positive. Finally we learned about another force diagram that has three arrows. This means there are forces pushing it up and down and there is one pushing it in another direction. For example a hockey puck. It the earth pushes it down, the ice pushes it up, and the shooter pushes it across.
How did you learn these ideas?
We learned these ideas because first Mr. Segen showed us force diagrams then, Laura had to hold a bowling ball up,in one hand, and a basketball in the other. Then Mr. Segen told us to draw a force diagram for this. Then this led to the number sentences and other force diagrams.
Why is it important to know this idea (What real world application is there)?
It is important to know this idea because one day I could be a teacher and my students might ask me what forces interact with a hockey puck being hit. Then I could think back to 8th grade science and tell them the earth's force, the ice's force, and the player's force.
