Fun With CO2!

In today's activity, we mixed two compounds, Sodium bicarbonate (Baking soda) NaHco3 and Acetic acid (Vinegar) CH3COOH in a large beaker. In the beaker was a burning candle. A chemical reaction occurred generating lots of bubbles. A few students noticed that the bottom of their beaker turned colder, indicating an endothermic reaction. The candle flame went out! The bubbles contained the gas Carbon dioxide, CO2. When the students went to relight the candle in the beaker, they were unable to. This was because the beaker was filled with the CO2. CO2 is heavier, or more dense, than air so it pushes the air out of the way. The air has Oxygen, O, in it. Without the Oxygen, you can't have a fire. Take a look at the video of this chemical reaction.

Who am I? I am a dull, bluish-gray, non-magnetic metal. I am the fourth most common metal in use and am used to coat steel to prevent rust and corrosion. I am also used in the alloy brass. In addition, I am used in some batteries and compounds of me are also used in deodorants and sunscreens. Small amounts of me are necessary for the human body. Pennies made after 1981 are made of of mostly me with just a thin copper coating.

Element of the Day! Wednesday, May, 28th


Who am I? I am a colorless, odorless, tasteless gas. I make up 78.08% by volume of Earth's atmosphere. I am an essential part of amino acids and nucleic acids, both of which are essential to all life - plants, animals, insects, etc. - on Earth. When I am in my liquid state, my temperature is -321 degrees F below zero and I can then be used for cooling and freezing things.

NASA's Phoenix Mars Lander!


On Sunday, NASA's Phoenix Mars Lander landed on Mars! Phoenix is on a three-month mission to excavate the soil on Mars using its 8-foot-long robotic arm to reach the ice believed to be buried inches to a foot deep. The lander will study whether the landing site could have supported primitive life. Among the things it will look for is whether the ice melted in Mar's history and whether the soil samples contain traces of organic compounds, one of the building blocks of life.

Go to NASA's Phoenix Mission web page for more information and photographs sent from the lander to Earth!

Working with compounds

Today in class we investigated compounds. Compounds are 2 or more elements that have been chemically combined. We used Manganese dioxide (MnO2) and hydrogen peroxide (H2O2). When mixed together, a chemical reaction occurred. A chemical reaction is a process in which substances undergo chemical change. One of the indicators of a chemical reaction includes bubbling, or the release of a gas.
When we poured the H2O2 into a beaker with some MnO2, bubbling occurred. We slowly lowered a glowing wood splint into the beaker and the splint burst into flames. this "glowing splint" test showed that the gas released was oxygen. Take a look at this video of the activity.

Who am I? Under regular conditions I am a dark-purple/dark-brown solid. I am primarily used in medicines to clean and disinfect wounds, photography, and in dyes. Table salt is often fortified with me. I am rare in the solar system and Earth's crust, however, compounds with me in them are very soluble in water and I am concentrated in seawater. I am necessary for the proper functioning of the thyroid gland in the human body.

Parker Community Day











The Parker Community Day was held last Sunday in cold, misty conditions. Nevertheless, many parents and students showed up to help clean up the school grounds. Weeds were pulled, mulch was spread, and a great pancake breakfast was served to all.








These photos are of the Bird Garden being cleaned up as part of Community Day. Four years ago volunteer parents and students designed and built this wonderful garden. It was designed with birds in mind. The plantings provide natural food and shelter for the birds. Teachers can take their students outside to make use of this garden for Art, Science, or Language Arts activities.

Model of an Atom Project

I would like you to make a model of an atom. It should clearly show the major parts of an atom: the nucleus which is made up of protons and neutrons, and electrons which travel around the nucleus in a “cloud”. Your model should show that there is empty space between the nucleus and the electrons. Label each part or make a key. Refer to the “All About Atoms” handout you received and use the Periodic Table of the Elements in your agenda for information.

Use your imagination and creativity in selecting materials for this project. It can be presented as a free standing model, or suspended from something like a coat hanger, or mounted on a poster board. Feel free to use gumdrops, mini marshmallows, jelly beans, Styrofoam balls, paints, fabric, cut paper, etc. to represent the parts of an atom.

Your grade will be based on:
* Demonstrating a knowledge and understanding of the parts of the atom
* A neat and creative visual presentation
* The model is original. It presents a familiar topic (the parts of the atom) in an unfamiliar way.


This project is due on, or by, Monday, May 5th, 2008
