Learning Objectives
Students will be able to list five characteristics of an ideal gas according to the kinetic molecular theory of gases.
Materials & Teacher-developed Resources
- Paper, pencils, textbooks, software
- Student handouts
- Popcorn, margarine, hot plate, beakers, food color
Learning Activities
- The teacher reviews basic properties of solids, liquids, and gases
- Few video clips will be inserted into a Power Point presentation to help students visualize aspects of kinetic molecular theory of gases.
- The teacher will perform the “Kinetic Molecular Theory with Popcorn” demo
- On the second day, the teacher will perform an experiment showing the students that the diffusion rate in a liquid (also a fluid) is influenced by temperature
Students will answer the following questions:
- When the temperature increases, do the particles move faster or slower?
- The particles of a gas are moving in a pattern or randomly? Explain
- What happens to the pressure inside a coke plastic bottle when you shake the bottle? Why?
- If you increase the number of molecules inside a balloon, what happens to the pressure inside?
