[Mini-Project Blogposts #4] ICE CREEEEAM!















photocredit: NatalieChung6


We made ice cream with rock salt in Mr. Olson's class!!!!!! YUMMM!



Ingredients:
  • 1 tablespoon sugar
  • 1/2 cup milk or half & half
  • 1/4 teaspoon vanilla
  • 6 tablespoons rock salt
  • 1 pint-size plastic food storage bag (or Ziploc)
  • 1 gallon-size plastic food storage bag
  • Ice cubes
Directions:
  1. Fill the large bag half full of ice, and add the rock salt. Seal the bag.
  2. Put milk, vanilla, and sugar into the small bag, and seal it.
  3. Place the small bag inside the large one, and seal it again carefully.
  4. Shake until the mixture is ice cream, which takes about 5 minutes.
  5. Wipe off the top of the small bag, then open it carefully. Enjoy!
You can put chocolate, strawberry, or caramel syrup in the small bag along with the milk, vanilla, and sugar to add flavoring! You can also add marshmallows or bunney mallows :) or sprinkles, too! YUMMM

Science:

Salt water freezes at a much lower temperature than fresh water so adding salt to ice makes the ice to melt and the temperature to drop. This cooling effect is used to freeze the ice cream.

Here is a molecule of NaCl, or AKA rock salt!

ChemStd 11d: Halogens: Alpha, Beta, Gamma

ChemStd 11d(Halogens): Students know the three most common forms of radioactive decay (alpha, beta, and gamma) and know how the nucleus changes in each type of decay.

There are three types of radioactive decays:

  • Alpha
  • Beta
  • Gamma
Radiation is energy traveling in the form of particles or waves in bundles of energy called photons. Some everyday examples are microwaves used to cook food, radio waves for radio and television, light, and x-rays used in medicine.



Alpha Decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle.

After the alpha decay, the nucleus changes to a mass number 4 less and atomic number 2 less.


4 He

2



Beta Decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted.

After beta decay, the nucleus has the same mass, but have a atomic number of 1 more.

0 E
-1



Gamma decay is when a nucleus in an excited energy state decays to a lower-energy state by emitting a high-energy photon. The photons produced in this decay are known as gamma rays.

After gamma decay, the nucleus's mass and atomic number stay the same.

[Mini-Project BlogPosts #3] Diet Coke + Mentos


Photo Credit: Mi Madre AKA My Mom.

Today, Mr. Olson created an explosion! Haha using mentos and diet coke!

Ingredients
  • Minted flavored Mentos
  • Diet coke
Directions:
  1. Open a liter of diet coke
  2. put mentos in it
  3. step away and experience the coolness
Science:

Dropping some Mentos into the bottle, usually around four, causes the Diet Coke to foam at a rapid rate and spew into the air. The mentos take away the carbon dioxide from the diet coke making it explode!

[Mini-Project BlogPosts #2] Making Water and Oil with Food Coloring!

Why doesn't water and oil mix? With the help of food coloring!

Ingredients:
  • Any food coloring
  • water
  • oil
  • bottle with a cap
Directions:
  1. Pour water in a bottle
  2. then pour oil in the beaker
  3. then put 5 drops of any food coloring
  4. then shake the bottle with the cap on
Science:

Water and oil doesn't mix because water molecules are polar – they have a small positive charge at one end and a small negative charge at the other end, and they stick to each other. Oil molecules are non-polar – they have no charge. Because of this, oil molecules are more attracted to each other than to water molecules, and water molecules are more attracted to each other than to oil molecules.

[Mini-Project BlogPosts #1] Play Doh

Photo credit: NatalieChung6

Ingredients:
  • 2-3 cups Flour
  • 1 and 1/2 cups Salt
  • 2-3 cups Water
  • 2 tablespoons Vegetable Oil
  • 1 tablespoons Cream of tartar
  • few drops Food coloring few drops
Procedure:
  1. Mix ALL of the ingredients in a large saucepan.
  2. Cook over medium low heat, until the dough comes away from the edges of the pan and it becomes difficult to move the spoon.
  3. Remove from heat. Cool until it can be handled.
  4. Place on counter or wax paper knead 3-4 times.
  5. Store in an air tight container.


Science:
When we make playdoh, it's hot, so when we touch it, it's squishy. But, if we leave it out and let it cool, the molecules packs up and then it hardens, so when we touch it, it is hard.

The Never Ending Mills Creek Canyon (WITH MyMAPS)

1, 2, LETS PLAY ZOO!

It was interesting, really. A hundred something students from Mills going to a never-ending hiking trip. Out of 10, I rate it 6. I thought there was a stop at a park with green grass and a beautiful creek or something. But, it was a never-ending rooooooooooadddddddd. . . *sob sob* I was panicking the whole time :( I'm scared of up and down steep hills hiking camping muddy slippery stuff because I know I will fall and trip and roll and bloop! But it was a great experience! YOU should give it a try, here's the directions to. . . Mills Creek Canyon from Mills High School!!!!

iProposeWe. . . MAKE ICE CREAM WITH DRY ICE!


Q: What's better th
an making ice cream with dry ice in chemistry class on a hot day?
A:
Nothing! (Laugh out loud!)


Links:
http://chemistry.about.com/od/dryiceprojects/a/dryicecream.htm
http://www.ehow.com/how_4789495_ice-cream-using-dry-ice.html



Ingredients:
  • dry ice (Don't know where to get it?)
  • 2 cups heavy cream
  • 2 cups half-and-half milk
  • 3/4 cup sugar
  • 2 teaspoons vanilla extract
  • 1/8 teaspoon salt


Materials:

  • mallet, hammer, or rolling pin
  • large mixing bowl
  • wooden spoon
Procedure:
  1. Use a mallet, hammer, or rolling pin to crush the dry ice.
  2. Mix heavy cream, half-and-half milk, sugar, vanilla extract, and salt in a large mixing bowl.
  3. Gradually add in the dry ice into the mixture after each stir.
  4. As more dry ice are added, it will start to harden and will get more difficult to mix. Continue adding dry ice until the ice cream has reached the desired consistency.
  5. Additional candy or sweets may be added for tasting.
  6. Freeze leftover if needed.
Safety Precautions:
  • Youngsters at a young age should have supervision by an adult.
  • The ice cream may be very cold! Use care when eating it to avoid frostbite or brain-freeze.
  • Dry ice is extremely cold and will hurt if contacted skin too long.
  • Use ice gloves when handling dry ice.
  • Be careful of surroundings when using a mallet, hammer, or rolling pin.
Scientific Principles:
  • Dry ice is a solid form of carbon dioxide used as a cooling agent.
  • Dry ice has a temperature; -109.3°F or -78.5°C.
  • Dry ice changes directly from a solid stage to a gas stage (which is also called, sublimation) without going through a wet liquid stage. That's where dry ice got it's name!

Shabu Shabu


I LOVE SHABU SHABU!
It's SO good.
Omg.
I'm going to faint.
They have two types of beef, lean kobe or .. regular?
Then you can choose from two different broths; spicy miso or regular miso.
Then they give you a bowl of rice, plate of veggies, and two delicious sauces; peanut and citrus soy sauce.
Omg.
I'm drooling. . . .

Cornell Notes



20 POINT QUESTION:

What do you think of cornell notes?
a) I LOVE it
b) It's okay, I guess.
c) It can go eat Momo's poop
d) I do it everyday

The correct answer is C, it can go eat Momo's poop.
You know, cornell notes are okay sometimes. But, it takes awfully LONG.
Now, I gotta ditch this and go cornell noting.

There's gas inside of you (David Webb and Vacuums)


That's right. There is.

Today David Webb, a cool vacuum scientist, and his wife, came here. Yes, here at Olson's class in Mills High School. There was so much that I learned, saw, and heard. David Webb had a really cool vacuum, well, he had a lot and there was a cool pump. Cool. Cool. Cool. Cool. Hah, Maryellen didn't know that the atmosphere consists oxygen!(I didn't know that either) Also, water boils at a lower Celsius temperature when it's under pressure. Also, in 1660, Robert Boyle was the first to show a vacuum is lethal to small animals.

The Energy Test




The energy test was the hardest test I'd took in chemistry class. I'm foreals. Half of the test was fulled of numbered problems and I was like... what? This test was 120 points and I'm really disappointed. There were 50 multiple choice problems and 1 problem with 5,000 numbers that was worth 20 points. No way, huh? Right now, I'm listening to a beautiful song to ease my stress.

FLAMING HOT


This is a random blog about my life. Right now, I'm blogging about blogging. Next to me, I have "flaming hot" Alberta Liao. ;) Alberta says, "I love One Piece Manga!" And across from me, I have Mary Ellen Hodge, and she a pyromania, if you didn't know. Ow, Alberta is poking me with a lime colored ruler.

"The Lab"


Quack Quack... does birds quack? In Olson's class, we did "The Lab" and it was kinda fun. We get to CRUSH diet coke cans and we were able to stare at The Happy Bird. It looks so happy. And I found out that why the happy bird drinks. ;) It's because of pressure!

The First Swim Meet


On March 18, 2010, it was Mills first swim meet against Carlmont in 2010. They were soo fast, I mean seriously. I didn't hear the results yet but I know we lost. But, we tried! That's the most important part. :) If you're interested to watch any future meets, just check our the Mills High School Swim Team Website.

Like Dissolves Like

DISSOLVING (<---- CLICK FOR MORE INFO)
1. To change a solid into liquid form (melt).
2. To cause to disappear or vanish (dispel).
3. To break into component parts (disintegrate).


In this figure, you see a solvent, aka water, dissolving salt, a solute.

-------------------

LIKE DISSOLVES LIKE (<---- CLICK FOR MORE INFO)
"like dissolves like" is an expression used by chemists to remember how some solvents work. It refers to "polar" and "nonpolar" solvents and solutes.

Example: Water is polar. Oil is non polar. Water(H2O) will not dissolve oil. Water is polar. Salt (NaCl) is polar. Like dissolves like so polar dissolves polar so water dissolves salt.

Winter Break

Alberta is mean. :(
2583838-10
LOL mr. olson said that.
anyways winter break was... i don't know.
well, i went to reno aka the "fake las vegas" so ugly! except for the snow:) i fell on the snow with my face flat down hahahhahahahahahaha hohohooho hahahah hehehehe haha hoho the ice was so freaking cold haha it tasted like hawaiian shaved ice... except without the flavoring. well winter break is over already. what do you think i am doing? writing a blog during winter break? U WISH!
