Mills Canyon Field Trip

Here's a map of the route to the park, Mr. Olson's Chemistry class went to. I did not go to the field trip, but looks like people had a lot of fun there and learned a lot of new stuff!

Mini Project: making ice cream

photo credit: me

ingredients

1. 1 cup of milk
2. 1 tsp of vanilla
   
3. 6 tbs of sugar
4. rock salt
5. ice
6. small sandwich bag
7. large sandwich bag

directions

1. pour the milk, vanilla, and sugar into the small sandwich bag
2. zip it up
3. fill half the bag of the big sandwich bag with ice and add a lot of salt rocks in there
4. put the small sandwich bag with ingredients inside of it into the big one
5. zip up the big one
6. start shaking the bag
7. shake for about 5-10 minutes or until ice cream starts to form
8. you can add syrup or toppings to your ice cream if you want
9. enjoy!
   

Mini Project: Defying Gravity

materials

1. a cup
2. 1/2 cup of water
3. piece of paper

directions

• fill cup with water up to half way
• take piece of paper and put it over the cup
• slowly turn the cup upside down
• slowly remove your hand from the cup
• you will see the paper will not fall down

science
the paper was able to stay up because of the different air pressure inside and outside of the cup. The air pressure outside of the cup is higher and the pressure inside is lower. It made it able for the paper to stay in place, and defy gravity.

Gravity: the force of attraction by which terrestrial bodies tend to fall toward the center of the earth.

Mini Project : Play Dough

IN CLASS WE MADE PLAY DOUGH! (:


ingredients we used
3 cups of all purpose flour
1 1/2 cup of salt
2 tbs of oil
food coloring ( if you want the play dough to have color)

directions

1. pour flour, salt, and oil into a big bowl
2. mix
   
3. add food coloring
4. pour play dough into a dish that is able to be put on the burner
   
5. have burner on high
6. stir while on burner
7. mixture should start to clump up and become play dough
   
8. have fun!
   

Chemistry Standard

Chem Standard 11g: Students know protons and neutrons have substructures and consist of particles called quarks.

A substructure is any basic structure or organization.

A quark is an elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons.

A hadron is a composite particle made of quarks held together by the strong force. Hadrons are categorized into two families: baryons ( made of three quarks), and mesons ( made of one quark and one antiquark). The best-known hadrons are protons and neutrons (both baryons), which can be found in the atomic nuclei. All hadrons except protons are unstable and undergo particle decay–however neutrons are stable when found inside the atomic nuclei. The best-known mesons are the pions and kaons, which were discovered during cosmic ray experiments during the late 1940s and early 1950s.

There are six types of quarks, known as flavors: up, down, charm, strange, top, and bottom. Up and down quarks have the lowest masses of all quarks. The heavier quarks rapidly change into up and down quarks through a process of particle decay: the transformation from a higher mass state to a lower mass state. Because of this, up and down quarks are generally stable and the most common in the universe, where as charm, strange, top, and bottom quarks can only be produced in high energy collisions.

The proton is a subatomic particle with an electric charge of +1 elementary charge. It is found in the nucleus of each atom, along with neutrons, but is also stable by itself and has a second identity as the hydrogen ion, H⁺. It is composed of three fundamental particles: two up quarks and one down quark.

The neutron is composed of one up quark and two down quarks.Video about quarks

PROPOSAL: MAKING CLOUDS

PRE LAB DISCUSSION
Removal of the stopper from an any opaque bottle or container results in the delayed evolution of a large cloud of water vapor some what like the mystical "jinni".

MATERIALS

• Hydrogen Peroxide, H2O2
• Potassium Iodide, KI
• A large Bottle
• Stopper
• Rubber Gloves
• Tea Bag
• Safety Goggles
• Table Spoon

SAFETY PRECAUTIONS

• WEAR RUBBER GLOVES
• WEAR SAFETY GOGGLES
• CONTACT WITH HYDROGEN PEROXIDE MAY CAUSE BURNS

SCIENTIFIC PRINCIPLES

• Water Vapor is the gas phase of water
• Water Vapor is lighter or less dense than dry air

PROCEDURE

1. Obtain a large opaque bottle and a stopper or cap to fit.
2. Add 30-50 mL of 30% hydrogen peroxide to the bottle. CAREFUL: WEAR RUBBER GLOVES and SAFETY GOGGLES. WHEN HANDLING 30% HYDROGEN PEROXIDE. CONTACT WITH THE SKIN MAY CAUSE BURNS.
3. Remove the tea from a tea bag and refill it with 1/4 table spoons of solid potassium iodide. Tie the tea bag securely with its string.
4. Place the tea bag inside the neck of the bottle. While holding the string/ insert the stopper to hold the bag in place.
5. When ready to perform the demonstration/ remove the stopper and allow the tea bag to fall into the hydrogen peroxide. Be sure to point the neck of the bottle up and in a safe direction.
6. Within a few seconds, an exothermic reaction in the bottle will produce a large amount of oxygen gas and water vapor that will form an impressive cloud as it escapes from the bottle.

so i didn't go to school on

March 23, 2010

I MISSED OUT ON THOSE PEOPLE THAT CAME TO OUR CHEM CLASS.

sooo i have to right about vacuums...?


that right? ^ haha! JK!

sooo here's a link to the real vacuum thing im talking about.
