Objective
1. Students will be able to identify and define the three most common states of
matter: gas, liquid, and gas.
2. Students will be able to visualize the three states of matter, gas, liquid and
solid by simulating molecules in motion.
Materials: Students, Classroom with desks set up in rows (at least two)
Procedure:
1.
|
Initiate a discussion about what matter is and that matter is all around us, have students identify things made of matter.
|
2.
|
Activate prior knowledge that all matter is made up of molecules tell students that today they are the molecules.
|
3.
|
Instruct students to get out of their seats and move about the classroom, no space is off limits (except up on things)
|
4.
|
As the students are moving about the classroom, sometimes bumping into one another ask "What state of matter are you molecules? A solid? A liquid or a gas?
|
5.
|
After a few minutes guide students toward the rows of desks, place a chair on one end blocking the row off, move to the other end of the row and place another chair. The students will still be able to move but now they are confined to the space between the rows. Ask the students to differentiate between the way they are able to move now compared to how they were able to move when they were a gas. Ask students "what state they are now in?"
|
6.
|
Lastly, to simulate a solid push in the chair on one end of the row until the students are "packed" together, able to only "vibrate" Again ask the students "what state they are now?"
