Hands-On Activity #1
Dry Ice Balloon
Science Area: Physical Science- States of Matter                     5.27- All material is a
solid, liquid or a gas
Materials:
    - tweezers    - balloon    -piece of dry ice
State Goals:
STATE GOAL 12:  Understand the fundamental concepts, principles and interconnections of the life, physical and earth/space sciences.
12.D.1b  Identify observable forces in nature (e.g., pushes, pulls, gravity, magnetism).
Safety Consideration:
    Be sure not to touch the dry ice with your bare hands!!!
Science Process Skills:
    -Observation
Math Process Skills:
    -None
Procedure:
1. Take the balloon and have one person hold the neck open.
2. Using the tweezers, grab the dry ice and place it into the balloon through the neck.
3. Tie the neck of the balloon and observe the balloon and observe it expand.
Explanation:
    As the inside of the balloon is closed off, the dry ice is changing its state from a solid to a gas.  As the dry ice gets warmer and more gas is increased, the balloon will expand since the gas cannot escape.

Hands-On Activity #2
Oobleck
Science Area: Physical Science- States of Matter                     5.27- All material is a
solid, liquid or a gas
Materials:
    - Corn Starch        -Water        -Container
State Goals:
STATE GOAL 12:  Understand the fundamental concepts, principles and interconnections of the life, physical and earth/space sciences.
12.C.1b  Compare large-scale physical pro­perties of matter (e.g., size, shape, color, texture, odor).
Safety Consideration:
    Make sure no one slips on the water.
Science Process Skills:
    -Observation
Math Process Skills:
    -Measurements
Procedure:
1. Pour 1 cup of water into the container.
2. Then add 1 and ½ cups of corn starch to the water and mix them together.
3. After they are mixed well enough, take the oobleck out of the container and play with it.
Explanation:
    When the water and corn starch are mixed together, they create an interesting substance called oobleck.  As you apply pressure to the substance, it acts as a solid and appears to be dry, but once you let go of the mixture, it will appear to be a liquid.

Hands-On Activity #3
Hydrogen Peroxide Meat
Science Area: Physical Science- States of Matter                     5.27- All material is a
solid, liquid or a gas
Materials:
    - Piece of hamburger meat    -Hydrogen Peroxide    -Water
State Goals:
STATE GOAL 12:  Understand the fundamental concepts, principles and interconnections of the life, physical and earth/space sciences.
12.C.1b  Compare large-scale physical pro­perties of matter (e.g., size, shape, color, texture, odor).
Safety Consideration:
    Make sure no one slips on the water.
Science Process Skills:
    -Observation
Math Process Skills:
    -None
Procedure:
1. Take the piece of hamburger meat and place some water on it and observe.
2. After nothing has happened, add a little bit of hydrogen peroxide and observe what it does to the meat.
Explanation:
    Water is comprised of two hydrogen molecules and one water molecule.  Hydrogen peroxide is two hydrogen and two oxygen molecules.  Both hydrogen and oxygen are gases, but together they form a liquid.  When poured on meat(solid), the meat begins to fizz up.  This is because the hydrogen peroxide takes the oxygen out of the area, with is what you see fizzing up.
