I used scientific text to find out about phosphorus. I did this so that I could complete a project or thought and back it up with evidence. I also so did this because it would make sure that what I said on my project wasn't true or could be misunderstood.

MIXTURE COMPOUND
An atom is what makes up the earth and everything we know of. An atom is made up of four things, a nucleus, protons, neutrons, and electrons. The nucleus is the center of the atom, protons and electrons are the things that make it. A proton it what makes up the nucleus, it is also what gives an element on the periodic table of elements it's periodic number. Let's say that a atom has 3 protons then it has a periodic number of 3. Also a proton has an positive electric charge, that is why some people put plus signs on it when they draw it.
A neutron is another part that makes up the nucleus, a neutron has a neutral electric charge. An electron travels around the nucleus and creates almost a barrier around it, fun fact the number of protons in an atom is the same as the number of electrons let's say you had 9 protons you would have 9 electrons. Electrons have a negative charge.
An element is made up of molecules. A molecule is when two or more of the same type of atom chemically bind together. When we make these into elements then we can sort them in the periodic table of elements which is organised by periodic number. A periodic number in the number of protons in an atom, each substance or element has it's own periodic number, like hydrogen has a periodic number of 1.
A mixture is when two different substances or elements are forced to mix together by physical bonds, when this happens no chemical reaction occurs so that makes it so you can separate the two substances or elements from one another. This is like a compound but they can be taken apart.
A compound is when two different substances or elements combine chemically so that a chemical reaction occurs. Once this happens their is no going back and you can not separate them again. You know that a chemical reaction has occurred when your senses sense something different about the substance.

In science I explained molecules, atoms, compounds, and mixtures. I did this by making sure that all the detail that was needed to be able to explain this in a kid friendly way but still complicated enough for grown ups and older kids to understand. I also made sure that my work was correct by using the stuff that my teacher said and paraphrasing it to a way that it had the proper and right meaning. Then I wrote about it which finished the explanation through my work properly and efficiently.

M&M experements

Do other colors dissolve faster than others? In order o find this out you will need a flat surface, different colors of M&M's, as many plates as M&M's with two circles on it, a ruler, and a plastic cup. To start put the plate on the flat surface. Then fill the cup with water and fill one plate and then repeat till all plates are filled. Then you put one M&M in and start counting once it reaches the first circle measure how many centimeters till the next circle and keep counting. Once it has reached the last circle you divide the amount of time ( in seconds) by the area it traveled in Centimeters. The answer that you get is the speed, repeat. So, do some colors dissolve faster than others.

In class we asked two scientific questions. The first scientific question is do M&M's dissolve in water. We found out in our experiment that they do. The second scientific question that we asked is do certain colors of M&M's dissolve faster than others the answer is no. Even though one dissolved like a tenth faster that is like no difference so the answer is no.

Weather
http://www.weatherforkids.org/images/wind-tree.jpg
Fronts are what happens when cold air and hot air met. What you would need to make a front is hot air and cold air. This makes a front because the cold air comes and pushes up the warm air. When this happens the weather it probably not going to be on your side. A warm front is when you are on the side that the warm air is, a cold front is where you are on the side where the cold air is.
High and low pressure systems are what controls clouds. When you are in high pressure you will have little to no clouds. Why is their little to no clouds? This happens because the high pressure squeezes the water in the air so it can't expand and make clouds. When it is high pressure you can expect it to be sunny and warm. When you are in low pressure you can expect cloudy skies. Why are there lots of clouds? There are lots of clouds because the low pressure allows the water molecules to expand and make clouds. You can also expect storms and cold temperatures.
Have you ever wondered how weather forms? Well if you have you came to the right place. Weather forms by using high and low pressure systems, fronts, the water cycle, and wind. One of the main things that keeps our weather going is the convention current. This is the way that the wind blows, In a circle. The warm air goes up and to the side then it cools and goes down to the opposite side and repeats.

In class we made a cloud in a soda bottle. This helped me with understanding how low pressure and high pressure effect the weather. I also helped me learn how clouds are made and what you need to make them. It also helped me understand why clouds usually form over firers.

Charity fair
After what we did in language arts we had to trace our supplies back to where they came from and find the amount of CO2 that we put into the air every time we get the product. To do this we had to see where the product came from. Then we had to find out how it got to San Jose and how much CO2 that went into the air when it came over. After that we had to find out how far it was (in kilometers) to get here. After that we had to figure out how much of it did we need for our project. If you need a lot then it would be a thousand if you need a good amount it would be five hundred if you need a little then it was two hundred fifty.
After we figured all of this out we had to multiply the amount we need by the amount of CO2 that went into the air when whatever we brought it in gave away and then we multiplied that by the distance. The product that we got is the amount of CO2 that went into the air every time we shipped over that product. The next thing we had to do was we had to pick one product from our list of stuff that we needed to make the product and we had to write a whole paragraph about how we could reduce that amount. For ours we choose the plastic bags that we got from China. Originally it would have come on an airplane but the way that we choose to reduce the amount of CO2 that went into the air we decided that we could bring it over by boat and that made the whole number go down.
After doing this in math class we had to figure out how much it would cost us to make ten of our product. First we had to figure out how much it cost us to make one and then we multiplied that by ten. After we found out how much it cost us we found out how much we wanted to sell them for then we multiplied that by ten then we subtracted the amount that it cost us to make it and the was our answer on how much we would make if we sold ten of our item. After that we had yo do the same steps to find out how much we would make if we sold 1000 and 1000000 of our product.
In elective we had to make our trifold poster that would stand outside our table and have all of the work that we did printed and pasted on to the poster. What we needed was to have our ignite presentation and our math calculations our carbon footprint and our step by step instructions on how to make our product. In elective we also set up for the charity fair and sold it to the parents and to the oak grove school district.
Backward looking
I think that I could improve by next time not just saying what our product is and what charity we are doing it for but instead say the process of making the product and about the carbon footprint and the math calculations. I think that this would help us improve because then we could be more convincing about why they should buy our product. I also think that next time we should make more of our product because we sold out.
Inward looking
I think that our work payed off because we raised a lot of money for our charity and we sold out. I really like the way that the trifold poster came out and I think that that was a success. i liked the way that the letters that we cut out turned out and how the back round wasn't all white and plaine. I think that the one thing that I would have changed was the language arts presentation and the presentation on exhibition night.
Outward looking
I think that we were different from the others because we were the only ones that was selling our item and we also were the only charity that was a breast cancer charity. I think that we were different as while because our poster didn't look the same and we were the only people in the classroom that had free samples. We were similar to other groups because we had a trifold poster and was selling items. I also think that we were similar to other people because we all had to do the carbon footprint the math calculations and the ignite presentation.
Forward looking
One thing that I would change if we had more time was make more of the product and earlier on in the time that we were selling start advertising the fact that we had free samples. I also think that something that I would work on is making sure that I have enough change for a twenty dollar bill just in case the teacher is not around when someone hands me a 20 dollar bill or something that we can't make change for so that we don't have to turn away customers or make them wait while we try to find the teacher to get change.
