Objective: At the end of this activity, you should be able to explain that particles of matter move and have space in between.
Materials: 1 piece 30 mL plastic syringe (without needle), transparent glass, 1 cup of water, 1 piece dinner plate, and silver spoon.
Directions:
Write your observations; Answer Questions 1-5 with YES or NO.
Procedure:
A. Pull the plunger of the syringe until it reaches the 30 mL mark. If a plastic syringe is not available, just refer to the picture below.
1. Cover tightly the tip of the syringe with your thumb. Can you push the plunger?
2. Do you think there is space between particles of a gas inside the syringe?
B. Let your syringe suck water from the cup up to 30 mL.
3. Again, cover tightly the tip of the syringe with your thumb. Can you push the plunger?
C. Transfer the 30 mL water from the plastic syringe to a transparent glass.
4. Is the shape of water changed?
D. Place a silver spoon in an empty cup, then transfer it to the plate.
5. Does the shape of the spoon change?
The air inside the syringe is compressed from 30 mL to 15 mL. The water flow as you transfer it from syringe to a transparent glass, then take the shape of the glass. The shape of spoon was not changed. Are the particles of matter moving? What is in between them?
