Lesson plan of Genetics: Introduction

Objectives (5 - 7 minutes)

1. Understand the concept of genetics: The teacher should help students understand what genetics is and how it is important for understanding the biological world. This includes explaining heredity, the structure of DNA, and the basic concepts of genes and alleles.

2. Understand the importance of genetics in everyday life: Students should be able to realize how genetics affects their daily lives. This can include discussions about genetic diseases, DNA testing, genetic modifications in plants and animals, among others.

3. Apply genetics knowledge to practical situations: Students should be able to use what they have learned about genetics to solve practical problems. This can include predicting inheritance patterns in family trees, interpreting DNA test results, among others.

Secondary objectives:

• Promote critical thinking: The teacher should encourage students to question and think critically about the presented genetics concepts, as well as their ethical and social implications.

• Stimulate interest in genetics: The teacher should seek to arouse students' interest in this field of biology, showing its relevance to medicine, agriculture, biodiversity conservation, among others.

Introduction (10 - 15 minutes)

1. Review of previous content: The teacher should begin the class by reviewing the basic biology concepts that are fundamental to understanding genetics. This may include a review of cells, DNA, genes, and heredity. This review can be done by asking students questions, encouraging active participation and engagement from the beginning.

2. Problem situation: The teacher can then introduce two problem situations to arouse students' interest. The first may be about the similarity of physical characteristics between parents and children, and how this is related to genetics. The second may be about the possibility of predicting the occurrence of certain diseases in a family based on its genetic history. The teacher should ask students what they think is behind these situations, encouraging curiosity and reflection.

3. Contextualization: The teacher should then contextualize the importance of genetics in the real world. This can include examples of how genetics is used in medicine to predict and treat diseases, in agriculture to improve food production, and in biodiversity conservation to understand and protect endangered species. The teacher may also mention the recent explosion in the popularity of genealogical DNA tests and how this has impacted people's perception of their own genetic heritage.

4. Gaining students' attention: To gain students' attention, the teacher can share two curiosities related to genetics. The first is about the Human Genome Project, which mapped the entire human DNA for the first time. The second is about the discovery that all humans share more than 99% of their DNA, and that the difference of only 1% is what makes us unique. These curiosities can serve to pique students' curiosity and interest in the subject.

5. Introduction to the topic: Finally, the teacher should introduce the topic of the class - Genetics: Introduction. Explain that in this class students will deepen their understanding of genetics, learn how it affects their daily lives, and how they can apply this knowledge in practical situations.

Development (20 - 25 minutes)

1. Activity 1 - "My Genes, My Choices" (10 - 12 minutes)

   • Description: In this activity, students will simulate making decisions based on genetic information. They will receive a fictitious genetic profile, which will include information about physical characteristics, predispositions to certain diseases, and other characteristics. They will then have to decide things like: what type of diet to follow based on their predispositions to certain diseases, what type of physical activity to practice based on their physical characteristics, among others.

   • Step by step:

     1. The teacher divides the class into small groups and distributes the fictitious genetic profiles to each group.
     2. The students, in their groups, discuss the information contained in the genetic profiles and make their decisions.
     3. Each group shares their decisions with the class and justifies their choices based on the genetic information.

   • Objective: This activity aims to show students the relevance of genetics in their daily lives and how they can use this information to make informed decisions about their health and well-being.

2. Activity 2 - "Investigating Heredity" (10 - 12 minutes)

   • Description: In this activity, students will investigate the heredity of physical characteristics in their own families. They will choose a physical characteristic, such as eye color, hair texture, height, etc., and interview their parents and siblings to find out if this characteristic is hereditary in their family.

   • Step by step:

     1. The teacher guides students in choosing a physical characteristic to investigate and in preparing a list of questions.
     2. The students interview their parents and siblings, writing down the answers.
     3. The students, in their groups, analyze the data and try to identify inheritance patterns.
     4. Each group shares their findings with the class.

   • Objective: This activity aims to help students understand how genetics influences our physical characteristics and how these characteristics are passed from generation to generation.

3. Activity 3 - "Genetics Game" (5 - 8 minutes)

   • Description: In this game, students will test their genetics knowledge in a fun and engaging way. They will be divided into teams and will compete to answer questions about genetics. The team that gets the most questions right will win the game.

   • Step by step:

     1. The teacher divides the class into teams and distributes the questions.
     2. The teams discuss the questions and decide their answers.
     3. The teacher collects the answers and announces the correct answers.
     4. At the end of the game, the team with the most correct answers is declared the winner.

   • Objective: This activity aims to reinforce genetics concepts in a playful and motivating way, encouraging cooperation and critical thinking.

Feedback (8 - 10 minutes)

1. Group Discussion (3 - 4 minutes):

   • The teacher should promote a group discussion with all students in the class. Each group will have a maximum of 3 minutes to share their solutions or conclusions from the activities carried out.
   • During the discussion, the teacher should encourage other students to ask questions and make comments, thus promoting interaction and exchange of ideas among the students.
   • The teacher should ensure that all groups have the opportunity to share their findings, ensuring that all students feel included and valued.

2. Connection with the Theory (2 - 3 minutes):

   • After the discussion, the teacher should return to the key points of the activities and connect them with the theory presented at the beginning of the class.
   • The teacher should explain how the practical activities helped illustrate and deepen the theoretical concepts of genetics. For example, how the "Genetics Game" helped reinforce the understanding of different inheritance patterns, or how the "Genetic Decision-Making" activity showed the practical application of genetics in everyday life.

3. Individual Reflection (2 - 3 minutes):

   • To conclude the class, the teacher should suggest that students do a brief individual reflection on what they have learned.
   • The teacher can ask questions like: "What was the most important concept you learned today?" and "What questions are still unanswered?"
   • Students should have a minute to think about their answers, and then they will have the opportunity to share their reflections with the class.

4. Teacher Feedback (1 minute):

   • To conclude, the teacher should give general feedback on the class's participation and performance during the class.
   • The teacher can praise the students' effort and dedication, comment on the interesting ideas that emerged during the discussion, and encourage the students to continue exploring the subject on their own.

Conclusion (5 - 7 minutes)
