Chemistry
Science in general makes me want to cry because its so confusing to me but i know once i understand I can have a blast learning that stuff, and Chemistry i believe will be the most fun of them all. Chemistry has several labs/projects/assignments throughout the year, and i think because of this hands on kind of teaching style it will be easier not only for me but all students to learn chemistry a little easier.
So far in Chemistry the only thing we have learned about is density and if it is intensive or extensive. Intensive meaning that density does not rely on shape or size of on object, extensive meaning density does rely on shape and size. We as a class determined that density is intensive, that density does not rely on shape or size. We determined this by starting with a few beakers filled with different amounts of water in them, we then placed a different amount of grams in all beakers, the amount of milliliters that were displaced after the grams were added gave us our volume of the object. The amount of grams that were added to a single beaker gave us our mass of the object. we then divided mass by volume the answer gave us the density of the object. We applied the same process to all of the beakers the density was the same for all objects even though different masses they still had roughly the same density and this proved that the density of an object is intensive.

Through gaining knowledge of how materials act when something happens to them, our past has been shaped by the chemistry of materials. By learning which materials can handle heat, which materials resist the most wear, which materials have a high tolerance for damage, we have learned which materials would be the best material for a specific use. Such as when ships replaced wood with metal because it had a higher damage threshold nor does metal rot in water after a period of time. In the future I am sure we will somewhere find that using a different material will be better for ships than metal.
