Project Title: Atoms and the Periodic Table
Objective: Explain atomic structure, isotopes, and periodic trends.
Project Instructions:
- 1. Draw a simple atom model for two elements.
- 2. Identify atomic number and mass number for each element.
- 3. Explain what isotopes are using one example.
- 4. Describe one periodic trend (atomic size or reactivity).
- 5. Consult your coach where necessary.
Evidence to Submit:
- • Atom models and labels.
- • Isotope explanation.
- • Periodic trend notes.
Submission
Part C: Training Others
Teach a peer about atoms and the periodic table.
Guidance:
- • Explain protons, neutrons, and electrons.
- • Demonstrate how to read atomic number and mass.
- • Discuss one periodic trend with examples.
Reflection:
- • What did the learner understand well?
- • What needed more explanation?
- • What support do you need from your coach?
Submission
