3. Online Quiz: As a form of assessment, the teacher will create an online quiz with multiple-choice questions based on the reading and video. This will help the students review the material and gauge their understanding of the concepts.

In-Class Activities (25 - 30 minutes)

Activity 1: "Protein Synthesis Board Game" (15 - 20 minutes)

1. Setup: The teacher will divide the students into groups of 3-4 and provide each group with a "Protein Synthesis Board Game" kit. The kit will include a game board, dice, game cards with different amino acids, RNA codons, DNA bases, and various proteins, and colored pieces to represent different parts of the protein synthesis process.

2. Game Instructions: The teacher will explain the game rules. The objective of the game is to correctly synthesize a protein by rolling the dice and moving the pieces on the board. The players will need to match the codons on their RNA cards with the appropriate amino acids to build the protein. The first group to successfully complete a protein wins.

3. Game Play: The students will play the game, discussing and strategizing as a group. The game will help reinforce their understanding of the protein synthesis process in a fun and interactive way.

Activity 2: "Protein Detective" (10 - 15 minutes)

1. Problem Setup: The teacher will present a problem to the students. Each group will be given a case file with a different scenario related to proteins and a set of clues (related to the various types and functions of proteins) to help them solve the problem. For example, a case file might be about a person with a genetic disorder caused by a missing enzyme.

2. Investigation and Solution: The students will read the case file, discuss the clues, and work together to figure out the solution. They will use their knowledge of proteins and protein synthesis to identify the problem (e.g., the missing enzyme in the case of the genetic disorder) and propose a solution or treatment.

3. Presenting Findings: Each group will then present their case to the class, explaining their thought process and the solution they came up with. The teacher will provide feedback and facilitate a class discussion on the different types and functions of proteins and the importance of protein synthesis.

These activities will not only reinforce the students' understanding of the topic but also encourage collaboration, critical thinking, and problem-solving skills in a fun and engaging way.

Feedback (5 - 7 minutes)

1. Group Discussion: The teacher will facilitate a group discussion, asking each group to share their solutions or conclusions from the "Protein Detective" activity. This will provide an opportunity for students to hear different perspectives and understand how their peers approached the same problem. The teacher will guide the discussion, linking the students' solutions to the theoretical concepts learned in the pre-class activities and the "Protein Synthesis Board Game" activity.

2. Connection to Theory: The teacher will then take a moment to connect the conclusions from the group activities to the theoretical concepts of protein synthesis.
