(2 - 3 minutes)

2. The teacher then presents two problem situations to the students:

   • The first problem could be about a child asking why they look like their parents. This leads to a discussion about the passing of genetic information from parents to offspring.
   • The second problem could be about a teenager asking why they start to experience changes in their body during puberty. This leads to a discussion about the role of the reproductive system in these changes. (2 - 3 minutes)

3. The teacher contextualizes the importance of the subject by explaining how the understanding of the human reproductive system is essential for personal and public health decisions. For example, understanding the process of reproduction can help in family planning, and knowledge about puberty changes can help teenagers navigate this stage of life with confidence. (1 - 2 minutes)

4. To grab the students' attention, the teacher shares two interesting facts or stories related to the topic:

   • The teacher could share the story of how Gregor Mendel, an Austrian monk, discovered the basic principles of heredity by studying the traits of pea plants. This can highlight the importance of understanding the principles of reproduction.
   • The teacher could also share the fact that the human body produces around 300 million sperm cells every day, which can travel about 7 inches per hour. This can make the students curious about the incredible processes happening inside their bodies. (2 - 3 minutes)

The teacher also emphasizes that the game is designed to be fun and educational, and the first group to complete the journey will receive a small prize.

3. Game Play: Each group rolls the dice and moves their game piece along the board. The students then pick a card from the deck and read the question or problem aloud.

4. Question/Problem Answering: The group collaboratively discusses the question or problem and writes down their answer or solution on a piece of paper. They can also use their pre-class notes and the video they watched for reference. The teacher circulates the room, providing guidance and answering any immediate questions that may arise.

5. Verification Step: After each group has provided their answer or solution, the teacher reveals the correct answer or solution and discusses it with the whole class. This step allows for a collaborative learning environment and provides an opportunity for students to learn from their peers.

6. Progress and Recap: The group moves their game piece forward if their answer or solution is correct. The teacher also uses this time to recap the main points of the questions or problems, reinforcing the lesson's learning objectives.

Activity 2: Reproductive System Diagram Collage (10 - 13 minutes)

1. Group Assignment: Each group receives a large poster board, a selection of magazines or printed images, scissors, glue sticks, and markers. The teacher explains that the task is for each group to create a diagram collage of the male or female reproductive system. The collage should be creative, visually appealing, and accurately represent the different organs and their functions.

2. Collage Creation: The students cut out images from the magazines or printouts that represent the various organs and parts of the reproductive system. They then arrange and glue the images onto the poster board in the correct positions and write the names of the organs next to them. Using markers, they draw arrows to show the flow of gametes and the process of fertilization.

3. Presentation: When all the groups have completed their collage, they present their work to the class, explaining each part and its function. The teacher encourages each group to ask questions about the other groups' collages, fostering an interactive and engaging learning environment.

4. Classroom Display: The teacher can decide to display the collages around the classroom as a visual reminder of the lesson's content. This also gives students an opportunity to review the material throughout the school day.
