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.

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.

Hydrogen
Peroxide Meat

Materials:
- Piece of hamburger meat
-Hydrogen Peroxide -Water

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.
