Activity 01
Formal Debate: Is the Moon Worth It?
Divide the class into two teams. One team argues that we should spend billions on lunar exploration for scientific and inspirational reasons; the other argues the money should be spent on Earth's environmental issues. Students must use evidence to support their points.
Explain why the Moon appears to change shape over the course of a month.
Facilitation TipDuring the Structured Debate, assign roles clearly and provide a timer for each speaker to keep the discussion focused on evidence, not opinion.
What to look forPresent students with images of the Moon in different phases. Ask them to label each phase (e.g., Full Moon, First Quarter, Waning Crescent) and write one sentence explaining why it appears that way.

Activity 02
Inquiry Circle: Designing a Moon Base
Groups are given a list of lunar challenges (no air, extreme temperatures, radiation, low gravity). They must design a simple base that addresses these needs using available resources (like lunar soil or 'regolith') and present their blueprint.
Construct a model demonstrating the different phases of the Moon.
Facilitation TipFor the Moon Base design, provide graph paper and a scale (e.g., 1 cm = 1 km) to ensure realistic planning.
What to look forPose the question: 'If you were an astronaut on the Moon, how would the Earth appear to change shape in your sky as the Moon goes through its phases?' Facilitate a class discussion, encouraging students to relate the Earth's appearance to the Moon's phases as seen from Earth.

Activity 03
Gallery Walk: Australia in Space
Students create 'museum plaques' about different aspects of Australia's space history (e.g., The Dish at Parkes, the Australian Space Agency, or Indigenous astronomical knowledge). They display these and use a worksheet to find key facts from their peers' work.
Predict the next phase of the Moon given its current appearance.
Facilitation TipDuring the Gallery Walk, assign small groups to create a 2-minute summary of one Australia in Space display to share with peers.
What to look forProvide students with a diagram showing the Earth, Moon, and Sun in a specific alignment. Ask them to draw what the Moon would look like from Earth in that position and to name the phase. Then, ask them to predict what the Moon will look like one week later.

Generate Complete Lesson→A few notes on teaching this unit
Teaching lunar phases works best when students first observe the Moon over time to connect personal experience with the model. Avoid starting with the names of phases—instead, let students describe what they see and build the terminology gradually. Research shows that kinesthetic activities, like modeling with flashlights and balls, improve spatial reasoning about celestial movements.
Students will confidently explain the phases of the Moon using evidence, model the Earth-Moon-Sun system through discussion and design, and apply their understanding to real-world contexts like space exploration.
Watch Out for These Misconceptions
During the Structured Debate, watch for students who claim the Moon landings were faked without evidence.
Use the debate to introduce the activity by showing students NASA’s high-resolution images of Apollo landing sites taken by the Lunar Reconnaissance Orbiter. Have them compare these to the terrain described in astronaut reports and moon rock samples.
During the Collaborative Investigation, watch for students who believe the Moon is hollow or made of cheese.
Provide seismic data from Apollo missions and ask students to interpret the graphs showing Moon quakes. Guide them to identify layers (crust, mantle, core) and compare them to Earth’s structure using a table you provide.
