Kitchen Chemistry Memories

We say good-bye to Jessi, Alexa, Zoe, Robbie, Murphy, Russell, and Maysie. We will miss you !!!! (But, hey, you'll only be across the hall!)

Kitchen Field Trip

After the kitchen field trip, students created a product to show what they learned in the kitchen. We had a rap, a song, several posters, and a few written accounts.

We went in the freezer today. The temperature was 10 degrees below zero. Russell

The water in the dishwaster is 180 degrees. - Murphy

We learned that a convection oven works because there is a fan in the back that moves the heat around the oven. - Ethan

The food cooks faster in the convection oven. - Cole

We learned that every can and jello bag is bigger than the original. -Michael

The temperature inside the milk cooler is 32 degrees. - Hart

We brainstormed restaurant names. - Alexa

Second graders started making their own menus. - Jessi

The food in the kitchen is used within six weeks of getting it. - Caitlin

They serve more than 500 people a day in our cafeteria. - Kathleen

On Grandparent's Day they will serve over 1,000 people. - Robbie

They are already working on the turkey for Grandparent's Day. - Ethan

We saw a huge mixer. It was about ten times the size of the one you have at home. - Zoe

We went inside the refrigeration. It was 32 degrees. - Blake

S'mores (sort of)

S'mores are called that because once you try one, you want some-more. - Zoe

We tried to make s'mores but they wouldn't melt very much. - Alexa

Because of the wind and cool temperature, they didn't melt. - Maysie

We put them in boxes, lined with aluminum foil, and covered with black construction paper. - Cole

We were using solar energy. - Robbie

We put a coke bottle outside and put a mento in it. It exploded. - Blake

We learned a new term that astronauts use. It's called carbon dioxide bubble nucleation. - Zoe

The mentos have tiny pores. The mento looked the moon under the microscope. Each pore made a carbon dioxide bubble. - Cole

Mentos with a smooth surface don't produce carbon dioxide bubble nucleation. - Jessi

We saw a cool website with brain games. http://www.lumosity.com/ - Ms. Searcy

Egg-Citing Day in TAG 9.28.09

Get a Voki now!



I tried a soft-boiled egg. I did not like it. – Jessi

When you put a chicken bone in vinegar for a week, it will eventually get so soft you can bend it (even tie it in a knot). – Caitlin

You can take an egg and put it in vinegar. After a few days, you can rub off the shell and see inside of it. – Murphy

If you put a raw egg in boiling water, the egg my crack and some of the white will cook and leak out – makes it look like the egg has a hairdo. – Zoe

When you leave an egg in a bag for a week, it smells REALLY bad. – Russell

When you put baking soda in a cup and then pour vinegar in it, it’s like a volcano and it pours out the top. It’s a chemical reaction. – Cole

We played a game, boys vs. girls, on chemical and physical changes. - Blake

When you put marshmallows on a fire, a chemical change happens. – Michael

When you melt a candle’s wax, it’s a physical change. – Alexa

Cutting paper is a physical change. – Maysie

Burning a candle is a chemical and a physical change. – Jessi

When you put an old, rusty penny in lemon juice it will turn shiny. – Kathleen

A penny gets rust because of oxidates. – Jessi

The Statue of Liberty is green because of all that rust – 200 years worth. – Zoe

I tried soft-boiled eggs, also. I thought they were great. – Alexa

Old people like to put soft-boiled eggs on their toast. I think I’ll try it. – Caitlin

If you boil eggs too long, the water will evaporate and the eggs will explode. – Zoe

We look at food through microscopes and it looked weird. – Hart

You can get a microscope at Radio Shack for only $10. – Alexa

Things that sit out for a long time gets oxidation (rust). It gets all brown. – Ethan

If you cook an egg too long, the yolk will turn blue and green. - Murphy

From the Plate to the Stomach

Some things we did today:

We tried marshmallows dipped in cheese. Cheese-mallows. - Russell

We sat in a dark room and chomped on wintergreen lifesavers. When you chomped on them, they lit up in the dark. - Zoe

That is called bioluminescence. - Ms. Searcy

Fish that live deep under the sea where there is no light have bioluminescence. - Alexa

Sea creatures like gulper eel, jelly fish, flashlight fish, some shrimp, and squid all have bioluminescence.

We ate cow tongue !!!! Zoe

The students really liked the cow tongue. You can buy it in a Jewish deli in the meat section.

We measured the time between lighting and thunder. - Jessi

The distance mean of the lighting strikes was six miles.

We turned solid cheese into a liquid and then later it hardened back into a solid. - Cole

This was a physical change. - Ethan

We had fondue.

We dipped bread, apples and marshmallows into our fondue cheese dip.

How does food travel from a plate to a stomach?

Lift the food from the plate to the mouth.

Open the mouth.

Insert the food.

Chew – saliva mixes with the food.

Swallow.

Go to the epiglottis. It will close the trachea and open the esophagus.
Food goes down the espophagus. Muscles push it down – this is called peristaltis. Gravity helps move it down. Slimy mucus helps, too.

Into the stomach. Acid digests your food (chemical digestion). Muscles push the food around (physical digestion).

Today we learned about physical changes - Alexa

A physical change is a change in shape. - Cole

Water and ice - physical changes - Michael

An ice cream cone from Bruster's melting on a hot day - physical change - Murphy

Water and steam - liquid and gas - physical changes - Robbie

Rotting is a physical change - Zoe

We learned about chemical changes - Jessi

Mold growing on the bread - chemical change - Russell

Water is inside corn. - Murphy

Marshmallows can be smooth when you lick them. - Michael

Corn kernels that don't pop are called "old maids." - Hart

When you pop popcorn, the kernel turns inside out. - Zoe

Popcorn kernels explode because the heat makes the water steam. - Robbie

When you put Vitamin C on apples, it stops them from getting brown. - Caitlin

The Vitamin C keeps the air (oxygen) from getting to the apple. - Ethan

Marshmallows - did you know it had an "a" (not marshmellows). Alexa

A popcorn kernel contains about 14% water. - Cole

The water inside the kernel boils when it is hot. - Blake

You can heat kernels with hot oil. - Kathleen

One of the ingredients in marshmallows is blue dye. - Caitlyn

We washed our apple skins with soap and water. - Michael
