The teacher will also briefly touch upon the concept of cell division, which will be relevant to understanding how Monera reproduce.

2. Problem Situations: The teacher will propose two problem situations to pique students' interest and stimulate their thinking:

   • "Imagine you are a scientist who has discovered a new organism. It is a single-celled organism, and it doesn't have a nucleus. How would you classify it? Why?"
   • "Suppose you are an astronaut about to embark on a long space journey. One of your tasks is to find a source of food that can be easily stored and won't spoil quickly. Which type of organism would you choose? Why?"

3. Real-World Contextualization: The teacher will contextualize the importance of studying the Kingdom Monera by pointing out its significance in various real-world applications, such as:

   • "Did you know that bacteria are used to make some of our favorite foods like cheese and yogurt? They are also used to treat sewage and clean up oil spills!"
   • "Archaea, another group in the Kingdom Monera, are found in some of the most extreme environments on Earth, such as hot springs and deep-sea vents. Studying them can give us insights into how life might exist in other planets or moons!"

4. Topic Introduction and Attention-Grabbing Curiosities: The teacher will introduce the topic of the Kingdom Monera, explaining that it is one of the five kingdoms in which all living organisms are classified. It will be highlighted that this kingdom includes the most ancient forms of life on Earth. To grab students' attention, the teacher will share the following curiosities:

   • "Did you know that bacteria were the first living organisms on Earth? They appeared more than 3.5 billion years ago, long before plants and animals!"
   • "Some bacteria can survive in the most extreme conditions, like boiling hot springs and deep freezing temperatures. They are known as extremophiles, which means 'lovers of extremes'!"

Development (18 - 20 minutes)

Activity 1: "Classifying Monera"

1. Materials Required: Chart paper, markers, glue, pictures of different organisms (bacteria, archaea, and some eukaryotes), index cards with the names of different kingdoms (Monera, Protista, Fungi, Plantae, Animalia).

2. Procedure:

   • The teacher divides the students into five groups, each representing one of the five kingdoms.
   • Each group is provided with a set of pictures of different organisms and index cards with the names of the kingdoms.
   • The task is for each group to classify the organisms in their set, placing them on the chart paper under the correct kingdom.
   • Once completed, the groups will explain their choices to the class, with the teacher providing feedback and clarifying any misconceptions.

3. Objectives: This activity will help students visually understand how Kingdom Monera is classified among the other kingdoms. It will also introduce them to the different types of organisms within the Kingdom Monera.

4. Teacher's Role: The teacher will facilitate the activity, monitor the students' progress, and provide guidance as needed.

Activity 2: "Bacterial Colony Simulation"

1. Materials Required: Agar-agar powder, petri dishes, swabs, microscope, prepared bacterial cultures (can be ordered online or obtained from a local university).

2. Procedure:

   • The teacher explains that bacteria often form colonies, which are groups of many bacteria living together. To simulate this, each group will create their own "bacterial colony" in a petri dish.
   • The teacher preps the agar-agar (a gelatinous substance derived from seaweed) and distributes it among the groups.
   • The groups spread the agar-agar in their petri dishes using swabs.
   • The teacher then distributes the bacterial cultures, and the groups gently rub the swabs on the agar-agar, "inoculating" it with bacteria.
   • The dishes are sealed and placed in a warm, dark place for at least 24 hours for the bacteria to grow.
   • The teacher will remind students about the importance of hygiene and handling bacteria safely during the experiment.

3. Objectives: This hands-on activity provides students with a tangible representation of a bacterial colony, reinforcing the concept of unicellular organisms living together in a community. It also introduces them to the basic principles of microbiology and laboratory safety.

4. Teacher's Role: The teacher will guide the students through the experiment, ensuring that they handle the bacterial cultures safely and monitor the growth of the colonies.

Activity 3: "A Microscopic Journey into the World of Monera"

1. Materials Required: Microscopes, prepared slides of bacteria and archaea, student observation sheets.

2. Procedure:

   • The teacher divides the class into pairs and provides each pair with a microscope, a slide, and an observation sheet. The slides contain samples of bacteria and archaea.
   • Students use the microscope to observe the slides, noting down their observations on the sheets. They should focus on the organisms' shapes, sizes, and any visible differences between bacteria and archaea.
   • The teacher circulates to assist the students with using the microscope and answering any questions that may arise.

3. Objectives: This activity allows students to observe and compare different types of Monera under a microscope, reinforcing the concept of unicellular organisms and their unique structures. It also develops students' microscopy skills and powers of observation.

4. Teacher's Role: The teacher will support the students in using the microscope and encourage them to make detailed observations. They will also ensure that the microscopes are used correctly and handled with care.
