12th Grade Sexual Reproduction And Asexual Reproduction Lesson Plan Example

Topic: sexual reproduction and asexual reproduction

Objectives & Outcomes

• Understand the different types of asexual reproduction and the benefits and limitations of each type.
• Know the different types of sexual reproduction and the benefits and limitations of each type.

Materials

• Diagrams or images of different types of asexual and sexual reproduction
• Handouts with information on the different types of asexual and sexual reproduction

Warm-up

• Ask students what they know about asexual and sexual reproduction.
• Write their answers on the board and discuss as a class.

Direct Instruction

• Begin by discussing the basics of sexual reproduction, including the process of fusion of male and female sex cells (i.e. sperm and egg) to form a fertilized egg.
• Then, introduce the concept of asexual reproduction, explaining that this is a type of reproduction that occurs without the fusion of sex cells.
• Examples of asexual reproduction include budding, fragmentation, and parthenogenesis (development of an egg into an embryo without fertilization).
• Discuss the advantages and disadvantages of asexual reproduction vs. sexual reproduction.

Guided Practice:

• There are a number of classroom-friendly demonstrations that can be used to illustrate the process of sexual reproduction and asexual reproduction.
• For example, you can use a pair of onion plants to demonstrate sexual reproduction, showing how the male and female parts of the plant (the male flowers and the female flowers) come together to form a fertilized egg.
• You can also show how asexual reproduction occurs using a piece of an onion bulb. By cutting the bulb into multiple pieces and allowing the pieces to grow, you can illustrate how each piece can form a new onion plant without the need for fusion of male and female sex cells.
• For the Guided Practice section of this lesson, have students work in pairs or small groups to complete a worksheet that includes questions about sexual reproduction and asexual reproduction.

Independent Practice:

• For the Independent Practice section of the lesson, have students work on a project-based assignment that requires them to research and present information about a specific type of sexual reproduction or asexual reproduction.
• Students could choose to research a specific animal species that undergoes sexual reproduction, or they could focus on a specific type of sexual reproduction such as parthenogenesis. -They could also choose to research a specific type of asexual reproduction, such as fragmentation.
• For their project, students should create a presentation that includes information about the process of sexual reproduction or asexual reproduction that they have researched. This could be a traditional oral presentation, a written report, or a more creative presentation such as a poster or a video.

Closure:

• End the class by having each group present their project to the rest of the class.
• Have students share what they learned about sexual reproduction or asexual reproduction and what is unique about the process in their chosen species or type of reproduction.

Assessment:

• Observing students during the guided and independent practice activities to make sure they are able to identify the parts of the plant or animal and complete the tasks given.
• Collecting and grading the completed worksheets or independent practice projects.
