Info Needed: The moon looks different from night to night because it moves around Earth. Sometimes we see the whole moon, and sometimes we only see part of it. These changes are called moon phases. If you look at the moon each night, you can watch it slowly change shape, from a tiny sliver to a big round circle and back again.
Possible Projects:
- Oreo Moon 8 Phases (20–30 min) – Create all eight moon phases using Oreo halves to show how the moon changes over time.
- Oreo Moon 7 Phases (20–30 min) – A simplified version with seven key phases for younger learners or quicker sessions.
