Mini Project #2

The mysterious moving liquid:
in chem we observed a mysterious liquid that continuously moves. It was made with with either milk or glue or some white liquid, i am pretty sure that is was milk but what ever. then some food coloring was placed in just a drop of different colors. after a little bit of soap was dropped in and all of a sudden the whole mixture began to move:I can not tell if the science in this is, because its a solution or if its because of its properties so i am going to say that its both a solution and a liquid experiment of some sort.

Mini Project #1

The mysterious play-dough type thing...
In chem we made this mysterious dough like material. it was made with flour and oil or water or something liquid most likely water. we put in food coloring. then it was heated on a hot plate. it smelled pretty bad. after it was done it looked like this: (the thing on my nose :D )



the science here is the fact that we combined different reactants added some energy, to create one product or play-dough type thing. the reactants are the flour water food coloring and heat. the product of course was the play-dough. PEACE OUT!!!

Gas Molecules and Pressure Standard 4a

students know that the random motion of gas molecules and their collisions with a surface create the observable pressure on that surface

Pressure= force/area

The speed and amount of gas molecules are what cause the amount of collisions on the surface. The collisions apply force to that surface. The more gas molecules in a container the more pressure, because the molecules take up more space.


The pressure of a gas is the force that the gas exerts on the walls of its container. When you blow air into a balloon, the balloon expands because the pressure of air molecules is greater on the inside of the balloon than the outside. Pressure is a property which determines the direction in which mass flows. If the balloon is released, the air moves from a region of high pressure to a region of low pressure.


Take a soda bottle for example. When you shake the closed soda bottle the carbon dioxide is released inside the bottle. the random moving gas molecules continuously bounce and repel off each other in the small space above the liquid and the surface of the bottle. the force that is applied to each square unit is that amount of pressure that is on the bottle. You can notice that the bottle feels hard.

We went on a field trip for our chemistry class. it was really interesting, because all we did was walk through mills canyon. We looked at the beautiful scenery and noticed the chemical reactions taking place

IProposeWe

"IProposeWe" make HOT Salt Water!

Materials:

• A small pot

• A glass

• Some sort of Water dispensing devise (a faucet)

• At least one table spoon of salt

• A stove or hot plate, preferably a stove

Procedure:
1: Pour about 1 cup of water into your pot
2: Then turn your stove on and place the pot on top of the stove
3: In about 4 to 5 minuets take the pot off the stove.
4: You need to fill the glass 3/4 full with water.
5: Take 1 teaspoon of salt and drop it in the water
6: Stir the two together until the final solution looks clear.
7: FINALLY DRINK IT!!!!!................or not

Safety Precautions:
1: Make sure you always have a good grip on the glass, because if it drops it will shatter and break into a lot of sharp pieces.
2: Wear gloves, because when you pour the hot water into the glass you don't want the hot water to spill on your hands and burn you.
3: Make sure you do not spill the salt, because if you do you will bring bad luck on yourself, and no one wants that.....

Scientific Principles: The science in this is the fact the what you end up with is a solution. The water is the solvent and the salt is the solute, that leaves salt water as the solution. Stirring the salt allows the salt to diffuse throughout the water faster, and heating the water up just allows
the salt to diffuse even faster.

SWIM MEET AT M-A

Yesterday the Mills high swim team went to M-A, or mennlo athertin. We knew we were goin to get destroyed, but we were goin to try hard nyway. In the 50 meter freestyle me and my good friend timothy liang got 1st and 2nd, which was AWESOME!!!!!! then in the 200m relay we got third sadly but its okay cuz we were close to beating our time. which is 1:51. Overall the meet went really well and i thought we did really good against a team that is better than us.

David Webb!!

A guest speaker came to our class and showed us all these kool demonstrations, with his equipment. All of them were about vacuums and how they don't suck they create a low pressure system. he was a great speaker, and his experiments such as, the feather and the washer dropping at the same time, were really kool. i got a kool souvener too it was a crushed can. kinda funny. I really enjoyed his demonstrations and it was the highlight of my chemisrty year. PEACE!!
