Ice Cubes Pats of Butter
Burner/Hot Plate (2) Aluminum Pans
Empty Container with Narrow Neck Empty Bottles (Small)
Plastic Cups Crayons
Balloons Color Water
Baking Soda Glue
Introduce the topic of states of matter, and ask the students to observe the
demonstration very carefully. Then, open a can of pop and pour some into the
plastic cup. Point out to the students that matter has three (3) different
phases (solid, liquid, and gas). Ask the students how these words: solid,
liquid, and gas are related to what they have just observed? Next, display a
block of wood or ice, a balloon filled with air, and a pot of boiling water.
Make sure you tell the students that liquids have no definite shape. Show the
students pictures of a ball, football, basketball, and a bike tire. Ask the
students what each object is filled with? The students should answer air. Have
the students explain that air and water will be the same shape of the container
that holds it. Tell the students to observe the pot of boiling water for about
five (5) to ten (10) seconds. Point out that steam is a type of gas. Ask the
students if the steam comes out of the pot in a regular pattern? The students
should answer no.
1. Classify the following objects as solids, liquids, and gases according to
sight and touch: crayons, chalk, screws, blocks, water, dice, inflated

(Borax Solution: 1 teaspoon of Borax soap and 100 mL (20 teaspoons of
Ask the students the question: What product is being formed?
After completing each activity, each student will identify the properties of
matter and classify different substances as solids, liquids, and/or gases.
