Simpler Version:
Title: Discovering Atoms
Objective: To introduce 11-year-old students to the concept of atoms and their basic parts.
Materials:
- Chart paper or whiteboard
- Markers
- Small balls or beads (representing protons, neutrons, and electrons)
Introduction (5 minutes):
1. Begin the lesson by asking students if they have ever wondered what everything around them is made of.
2. Explain that everything, including themselves, is made up of tiny particles called atoms.
3. Write the word “atom” on the chart paper or whiteboard and ask students if they have heard of it before.
Main Lesson (15 minutes):
1. Explain that atoms are the building blocks of matter and are too small to see with our eyes.
2. Draw a simple atom on the chart paper or whiteboard, consisting of a nucleus (center) and electrons (orbiting around the nucleus).
3. Introduce the three main parts of an atom:
a. Nucleus: Explain that the nucleus is the central part of an atom and contains protons and neutrons.
b. Protons: Explain that protons have a positive charge and are found in the nucleus.
c. Neutrons: Explain that neutrons have no charge (neutral) and are also found in the nucleus.
d. Electrons: Explain that electrons have a negative charge and orbit around the nucleus.
4. Use the small balls or beads to demonstrate the parts of an atom. Assign different colors to represent protons, neutrons, and electrons.
Activity (5 minutes):
1. Distribute small balls or beads to each student.
2. Instruct students to create their own simple atom using the materials provided.
3. Encourage students to share their creations with the class.
Conclusion (5 minutes):
1. Recap the main points discussed during the lesson, emphasizing the three main parts of an atom: protons, neutrons, and electrons.
2. Highlight that atoms are the building blocks of everything around us.
3. Encourage students to continue exploring and asking questions about atoms and the world of science.

Title: Exploring the Atom
Objective: To introduce 11-year-old students to the concept of atoms and their parts.
Materials:
- Chart paper or whiteboard
- Markers
- Small balls or beads (representing protons, neutrons, and electrons)
- Sticky notes
- Handout with atom diagram (optional)

2. Draw a simple atom on the chart paper or whiteboard, consisting of a nucleus (center) and electrons (orbiting around the nucleus).
3. Introduce the three main parts of an atom:
a. Nucleus: Explain that the nucleus is the central part of an atom and contains two types of particles called protons and neutrons.
b. Protons: Explain that protons have a positive charge and are found in the nucleus.
c. Neutrons: Explain that neutrons have no charge (neutral) and are also found in the nucleus.
d. Electrons: Explain that electrons have a negative charge and orbit around the nucleus in specific energy levels or shells.
4. Use the small balls or beads to demonstrate the parts of an atom. Assign different colors to represent protons, neutrons, and electrons.
5. Emphasize that the number of protons determines the type of atom, and different atoms have different numbers of protons.
6. Discuss that atoms are mostly empty space, with the electrons occupying the majority of the space around the nucleus.
Activity (5 minutes):
1. Distribute sticky notes to each student.
2. Instruct students to write down one question they have about atoms or something they found interesting during the lesson.
3. Collect the sticky notes and briefly discuss a few questions or interesting points raised by the students.
Conclusion (5 minutes):
1. Recap the main points discussed during the lesson, emphasizing the three main parts of an atom: protons, neutrons, and electrons.
2. Highlight that atoms are the building blocks of everything around us.
