Poem- What's
the Matter?By: Tom
McGowen
What's the matter, do you ask? I'll tell you right away. It's everything around you, As you work or sleep, or play. A chair is matter, a table, too, And so is a rock or tree. A cloud, a star, a blade of grass, A raindrop, a bumblebee. The earth is matter, so is the sea, And the sky is matter, too. (Of course what matters most of all Is the matter that is you!) There's matter almost everywhere, Except in one special place-- The vast, black, lonely emptiness, That we call outer space.
Activity-Similar But Different• Which number ball do you think has the most
matter? ________
• Do NOT pick up the balls. Rank the balls in size, from largest to smallest. 2, 4, 5, 1, 3, 6
• Pick up the balls. Rank the balls by weight, from heaviest to lightest. 1, 3, 2, 4, 5, 6
Number ball Mass (g)
1 51 g
2 40 g
3 50 g
4 15 g
5 12 g
6 1 g
property• something about matter that you can observe with 1 or more of your senses
What are some properties of matter that you can observe?
• Size
• Shape
• Texture
• Smell
• Taste
• Sound
• Color

How do you know helium inside a balloon is matter?
• It takes up space.
What are two objects that have some properties
similar to the properties of a tennis ball?
states of
matter
solid
• keeps its shape
• particles packed tightly together –jiggle very fast
liquid• takes shape of its container
• particles are loosely connected
gas• no shape
• particles spread apart- fill whatever space is available
States of Matter Animation
pressure• pushing force of air
Air Pressure activity
1. Blow up both balloons so they are the same size.
2. Tape one balloon to each end of the yard/meter stick.
3. Tie a string to the center of the stick and adjust it so the stick balances when held by the string. Tape the sting in place to prevent it from slipping.
4. Ask the students, "If one end were heavier, would the heavier end move up or down?".
5. Supporting one balloon, have someone carefully deflate the other balloon. Try poking the balloon with a pin in its neck to prevent the balloon from tearing apart as it pops.
6. Release the remaining balloon and ask the students to explain what happens.
Since the inflated balloon weighs more than the deflated one, the side of the inflated balloon will drop. Imagine the weight of air if that balloon were now 15 miles (24 km) tall. That is actually what is occurring at this moment in your classroom. When we measure air pressure, we are measuring the weight of a column of air 15 miles (24 km) high directly over us.
Draw, color & label pictures of 2 solids, 2 liquids & 2 gases.

What are the particles of a solid like?
• The particles of a solid are packed tightly together and are firmly connected. They jiggle very fast but stay in place.

How can you tell the difference between a gas and a liquid?
• A liquid takes the shape of whatever it is poured into. It takes the same amount of space in any container.
• A gas has no shape at all, and the amount of space it takes up changes. It will fill all available space.
You know matter takes up space. If you pour orange juice into an empty glass, what happens to the air inside
the glass? How do you know?
• The air is pushed out of the glass, and the orange juice replaces it. This happens because two objects can not occupy the same space at the same time.
element• matter made of a single type of particle too small to see
HELIUM
atom
•smallest particle of an element that has the properties of that element
periodic table•way of arranging elements based on their properties
What is an element?
• An element is matter made of a single type of atom.
How are gold and iron alike and different?
• They are both elements. However, they are made of different kinds of atoms.
Is it possible to have an atom of paper? Why or
why not?
• No, because paper is not an element; it is a combination of different types of atoms.
