Free Gasses Lesson Plan for 10th Grade Students

Topic: Gases: Rules and Charles' Law

Objectives & Outcomes

• Students will be able to understand the concept of gases and the behaviors of gases under different conditions.

Materials

• Large balloons
• Small balloons
• Glycerin solution
• Fresh air (or other clean gases)
• Table salt
• Water
• Ice
• Heat source (e.g. stove, heater, etc.)
• Small bowls or cups
• Timer
• Pencils and paper

Warm-up

• Show the students a fresh air balloon and ask them to describe what they see. Then, have them rub their hands together and cup their hands around the balloon, slowly releasing their hands as they move them away from the balloon. Ask them to describe what they see.
• Explain that both of these demonstrations are examples of how gases behave under different conditions.

Direct Instruction

• Introduce the concept of gases and their properties, including their ability to expand to fill any available space and their ability to interact with other gases and objects.
• Discuss the different types of gases and their characteristics, including boiling point, density, and solubility.
• Show the students a few different types of gases and have them identify them based on their color and odor.

Guided Practice

• Have the students work in pairs to fill a container with a gas using a gas syringe.
• Have them observe the gas and describe its properties, including its color and odor.
• Ask them to calculate the gas' density based on its volume and mass.
• Have the students compare their gas to the gas in the other container and explain any differences they see.
• Review any terminology or concepts that the students are having difficulty with.

Independent Practice

• Have the students create a poster or presentation to teach others about the properties and behavior of gases.
• They should include information on density, volume, color, odor, and any other properties they observed during the activity.
• They should also include any safety precautions that need to be taken when working with gases.

Closure

• Review the main points of the lesson, including the differences between solids, liquids, and gases, and the properties and behaviors of each.
• Ask the students to share something they learned or found interesting about gases.
• Remind them to be safe when working with gases in the future.

Assessment:

• Observe the students during the lab to assess their understanding of the concepts covered in the lesson.
• Have the students complete a worksheet or quiz asking them to apply their knowledge of the properties and behaviors of gases to specific scenarios.
• Evaluate their work before they leave the class to ensure they understood the material.
