Invisible ink lab
Today in class we made invisible inc. I was made from 100 ml of distilled water, 1g of phenolphthalein, and 10 ml of ethanol. This experiment was by far one of my favorites, because its the first time we ever made something with harm full chemicals. I think it is cool that andrew trusted us harmful chemical.
Ocean Acidification
There is to much acid in are ocean. carbon from the air that's getting made frome factory and other harmfull places or things like cars, busses, and planes are releasing it. The carbon floats around the air and can get pulled into the ocean. HOW ? There are circulations in the ocean that move components in the air into the ocean and components in the ocean to the air. CO2 is taken in from the air to go into the ocean and threw the circulation the ocean releases H2co3 which is a mix of Co2 and H2o This acers when the to meet together in the ocean. This is what the acid in the ocean is, I also wanted to know how this would affect human and animal life in future years.

state of matter
|
To learn about state of matter andrew showed us how to make are own rocks. To make the rocks you have to get liquid glass and metal it doesn't mater what type of metal. You mix the calcium chloride and liquid glass and get little crystals. The reason i think the crystals grew was because the air was trapped
under the medal and made the crystals go up when the air rises. |
properties of matter
Properties of matter are how it looks feels and acts. because if you look at a gas or a liquid compare the gas to the liquid it is going to be lighter at most times. Andrew showed is a fun why on how to learn about it. We got 1 trash bag , four candles and tow things of balsa wood. We put the two pieces of balsa wood in an x shape and taped them together. We broke the candles in half then melted them on the wood. then we poked holes in the trash bag for the wood to rest in, we put tape to hold it in better. After that we lit the candles on fire and let it do its thing. The reason it was going up was because the candles were trapping the heat in the bag and we all know that heat rises and thats why the bag went up in the air.

what are the phases of matter
The phases of matter
Solid to liquid = melting
liquid to solid = freezing
liquid to gas = evaporation
gas to liquid = condensation
solid to gas = sublimation
gas to solid = deposition
Dry Ice
To day in class we got to learn about dry ice. We got experiment with it we did lots of experiments like putting it in water, putting coins on it and my favorite is andrew put it in a pressurized tube and shot it out. When dry ice goes into water it makes steam/fog . I think it makes this because the air is coming out of the ice when it is fully submerged in the walter and the air is coming up making this fog. The fog was different than normal it was more dense than normal fog i was told that that is what clouds are made of. The other experiment we did in my group was we put coins on ice and made it so the ice froze all the way around it. I think it froze around the coin because it was trying to get the coin the same tempchar as the ice. The ice in the pressurised tube when it got to 70 thru 80 PSI turned into water and then andrew shot the ice/ water out of the tube and into the air and made snow. I think it made snow because when the ice turned into water it was half way between solid and liquid..

Light
Everything revolves around light. Light is the biggest form of energy in are universe that we know about. i learned a lot of things in the lab about light like why plants are green and why the sky is blue. Plants are green because they can take in all light colors except green they don't have eney use for the green light so that is them spitting out the green when you see it on the stem or leaf. The sky is blue because all other light can make it out of the atmosphere but not blue the blue light is trapped so it is just floating there with nowhere to go and that's why the sky is blue. Fun fact the reason blue can't escape is because it's in the lighter side of the light spectrum unlike how red can leave because it's on the darker side of the light spectrum.
The pitcher above is is of a light wave scale red is at the highest wavelength and violet is all the way at the end with the shortest wave length when all of the waves are seen together they make white light. But when the white light shines thru a prism the light breaks up into the colors we see in the light spectrum.

what is science update
everything
science is all around us in our everyday lives. everything can be traced to science like cars which is a form of the mechanical branches of science to rocks which is geology all the branches of science have ties into I think a hypothesis is a educated guess and you make one to to guess what happens in a experiment or project
up date
science is a huge un none but the branch of science chemistry is a little part of the science pie.
I think chemistry is awesome it helps us all understand what is going on a molecular level like what's going on in an explosion or just mixing water, citric acid and magnesium to make hydrogen . i also think that science could be trying to understand more stuff around us and figuring out questions like why is the earth round and why are plants green
hypothesis
In chemistry class we made a hydrogen filled balloon by mixing water, citric acid and magnesium. we lit it on fire and it made a explosion. I believe the explosion happened because the hydrogen in the balloon had a reaction with the fire because most of the time when an object gets lit on fire it does not explode and leave a residue of fire on the floor. another reason I believe that because it bernt fast and there was no smoke after it bernt because on a normal fire of that size would have left a lot of smoke.
Up Date
When my class bernt the hydrogen filled balloons that we biult out of water, citric acid and magnesium a combustion happened that allowed atoms to rearrange into equal amounts of 8. the flame just helped ignite the balloon to make the fiery explosion that left a residue of flames in the air for a half second. This is really cool because before this i thought that it just lit on fire and went boom but know i know the there is a huge amount of other things that make it go boom like how you need to have 8 atoms to make a full molecule. I also learned a lot about the periodic table of elements like how potassium is K even though you would think it is a P put it comes from the medieval latin word kalium. I think that just in these first 4 weeks i have learned a lot about chemistry whether it is building rockets or lighting a hydrogen filled balloon on fire.

combustion
I knew a combustion was a controlled explosion that we used to helped us get are rockets in the air. I new that there were internal computation engines that use small explosions to push pistons up and down and turn the crank and threw gears in the transmission and rear axle make the tires move.I also knew in order to get are rocket in the air or car tires moving you need to have a ignition charge to spark the motor.I didn't know before reading the article how there are three key components that need to be there to make it lunch. you need a fuel ,oxidiser , and a ignition source. I also did not know that fuels for combustion com in gas, liquid, and solids i thought that only solds could be used as fuel for combustion.
