Simpler Version:
Activity: Building Molecules with Covalent Bonds
Objective: To introduce the concept of covalent bonding by building simple molecules using molecular model kits.
Materials:
- Molecular model kits (balls and sticks)
- Index cards
- Pen or pencil
Procedure:
1. Explain the concept of covalent bonding to the students, emphasizing how atoms share electrons to form stable molecules.
2. Divide the students into pairs or small groups.
3. Distribute the molecular model kits to each group.
4. Provide each group with a set of index cards and a pen or pencil.
5. Instruct the students to choose two different elements from the periodic table and write their symbols on separate index cards.
6. Ask the students to use the molecular model kits to build a molecule by connecting the atoms with covalent bonds.
7. Once the students have built their molecules, ask them to draw the molecular structure on the index cards, indicating the atoms and the bonds between them.
8. Have each group present their molecule to the class, explaining the elements involved and the overall structure of the molecule.
9. Conclude the activity by summarizing the key points about covalent bonding and its role in forming molecules.
