11th Grade Organic Compound Alkane, Alkines And Alkynes Lesson Plan (Science)

Topic: Organic compound, alkane, alkines and alkynes

Objectives & Outcomes

• Students will be able to define organic compound, alkane, alkine and alkyne.
• Students will be able to give examples of each type of compound.
• Students will be able to identify the functional group present in alkanes, alkines and alkynes.

Materials

• Whiteboard and markers
• Handouts with definitions and examples of organic compounds, alkanes, alkines and alkynes

Warm-up

• Ask students to name some common organic compounds (e.g. ethanol, methane, acetone).
• Ask students to explain what they know about these compounds.
• Write their responses on the board.
• Discuss the common features of organic compounds, such as their bonding structure and their origin from living organisms.

Direct Instruction

• Show the students the model of an alkane and alkene on the board.
• Discuss the structure and naming of organic compounds, focusing on the difference between alkanes, alkines and alkynes.
• Explain how to determine the number of carbon atoms in an organic molecule using the counting rule.

Guided Practice

• Have the students work in pairs to identify the number of carbon atoms in each organic molecule using the counting rule.
• Check the work as a class, using the model of the alkane, alkene and alkyne to show how the counting rule is applied.

Independent Practice

• Have the students work in small groups to experiment with the physical properties of the alkanes, alkenes and alkynes.
• Have each group choose one organic molecule and conduct experiments to observe its physical properties (melting point, boiling point, vapor pressure, etc.).
• Have the groups present their findings to the class, using a chart or graph to illustrate their results.

Closure

• Review the properties of the alkanes, alkenes and alkynes that were studied in the lesson.
• Ask the students to share what they learned about organic compounds and how their physical properties can be used to identify them.

Assessment

• Observe the students during the guided and independent practice activities to assess their understanding of the concept.
• Collect and review their written answers to the guided and independent practice activities to assess their ability to apply their understanding of the concept.
