Summary:
        There are lots of different kinds of galaxies and they are spiral, elliptical, peculiar, and irregular galaxies. Spiral galaxies have a red center because the center is made of older stars and the other stars, gas and things or the “arms” are shaped like a spiral and they are like flat disks. We live in the milky way and the milky way is a spiral galaxy. Elliptical galaxies are shaped like spheres or they can also be shaped like a football type shape, they are mostly made up of older stars. Peculiar galaxies have a weird and a hard to make out shape but they are mostly products of galactic collision. Irregular galaxies also have a weird and no distinct shape, and they larger ones are possibly caused by galactic collisions.

S&EP 1: Asking questions and defining problems:
        We asked a scientific question and it was, "how does the distance of a planet from the sun affect the planets?". Even though this seems super obvious the further away from the sun the colder the planets are and one of them even is made of partly ice. We also found out that the further away the planet are the longer the years are because it takes a longer time to actually orbit around the sun due to it being further. Another thing that we found out is that when the planets are further for the sun they can have a longer sunlight time like how uranus is the 7th from the sun and it has sun for around 42 earth years at a time. There are tons of other factors that make planets different like some are gas giants (they are mostly made of gas and have many rings and moons) and some are rocky planets9 mostly made of rocks and metal with no rings and few moons if there are any).

Summary:
       There are 8 phases of the moon and they are the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, wast quarter and waning crescent. The waxing stages are when the moon is "growing" from a new moon to a full moon and waning is when it is "shrinking" from a full to a new moon. The reason why it looks like their are different "stages" of the moon is because of how much is visible on earth.  The earth rotates which gives us days and nights and the moon orbits the earth which makes it get closer or further from the sun. The closer the moon is to the sun the less the moon shows and the further it is from the sun the more moon shows. The moon does not actually change its shape but it looks different because it orbits the earth. Each cycle the moon goes through takes about 29 days so it will look different on different day of the month.

S&EP: Developing and using models:
        We were doing a formative and we had to do lots of drawings to show the different phases of the moon and seeing what the moon was like on certain days. We had to see what phases of the moon would it be for this whole month  and we had to see what phase the moon was o during our birthdays. From looking and drawing these things I found out that on the day I was born and I found out I was born on a full moon and this year my birthday is going to be between a last quarter and a waning gibbous. I also found out that this month the full moon is going to be on the 1st, 29th and the 30th. We had t do lots of drawings of the phases of the moon to show what the moon will be like during certain times and all of the phases of the moon.

Summary:

       Sound is caused by molecules vibrating and then entering your ear and because of the fact that molecules are closer to each other in solids it travel 18 time faster then in air and it air sound travels the slowest. A crest in the top of a wave like a sound wave and a trough is the bottom of a wave. Amplitude is the height from the middle of a wave to the top, or the height of the wave and changing the amplitude will change how loud it is for sound waves. Frequency is how fast the wave is moving and vibrates and this is what changes how high pitched something is. Wave length is the length from one crest to the next crest or one trough to the next. There are two types of waves and they are mechanical and electromagnetic and the difference is that mechanical waves do need mater or a medium to pass through and electromagnetic don't. Sound is considered a mechanical wave because it does need a medium or matter to pass though like air, water or a solid.

Backward-looking: How much did you know about the subject before we started?
        Before we did this sound unit I knew the basics like how it is caused by vibrations and that there are sound waves but most of it was new. I knew that with air the molecules were spread further apart in air and they were closer together in things like solids but I did not know that sound traveled faster in solids. I also did not know  what the parts of  a wave were and what they represented but I knew what frequency and a few other words meant prior to this unit. I knew that tension was how tight or lose something was and I knew that to make something higher pitched you have to tighten or shorten it. I did not know and learned a lot from this like how there are multiple types of wave and I also knew a little bit before we did this.

Inward-looking: Have you changed any ideas you used to have on this subject?
        I think that this was something that was a challenge at the beginning because we had to change it quite a bit with the strings and then I was going to have the washers be on a nail but then I just bent a paperclip and different things. It was also hard to tune the straws because when you cut some off you can not just glue it back on so I was originally going to have 6 straws but then I took 3 of them off because they were bad. I also was going to but my rubber bands and then hot glue them but then they would come off and things so I tried to use a binder clip and that worked. I had to change some of my ideas to make my instrument better and in the end it made them so that they were better and it was not pretty and not perfect but it worked and it got the job done. I wish I could have done a little better but I still think it was good. 

Outward-looking: Did you do your work the way other people did theirs? In what ways did you do it differently? In what ways was your work or process similar?
        I think that everyone had a similar work process and we would all make our instrument and then we would learn more about sound from different assignments and then make changes to our prototypes. It was similar because we all ad to make an instrument made with everyday items and then we also had to make it have 3 notes on the percussion, strings and wind. We also did it in a similar way because lots of people used pipes, straws, card board, rubber bands, and more. It was different because everyone's looked and sounded different then the others. Everyone's instrument played different notes and sounded different them the others but that is what made everyone's great.

Forward-looking: One thing I would like to improve upon is ...
Something that wish I improved on it how it looks because it looks kind of messed up and there are some parts that are colored with sharpie. I wish that I added some sort of paint or something to make it so that the instrument did not looks so messed up and so that it did not look as plain as it does. I also wish that I made it so that you could tune it and I wish that it would have more notes with the wind. I think that I did good but I also could have used something other then washers so the different jingling noises sounded more different from each other. I got a good score on the project and I think that I like how it turned out but it could have been better.
