Students name and describe Earth's four spheres, give examples of matter and processes in each, and recognise that spheres overlap and interact (AC9S9U03, node 1, a hinge node).

A concept tutorial for introducing or revising the idea. Set the width with ?width=minimum, typical (default) or wider.
The hinge is the framework itself: students who can't place things in spheres can't place carbon flows between them. The board accepts two answers for the cloud (atmosphere or hydrosphere) and the soil (geosphere or biosphere) and explains why.
Board notes: a simple drawn landscape; students click a thing, then choose its sphere. The wider question on cool burning is general; use local First Nations sources for detail about practice on your Country.
Placing things that sit in two spheres at once. When a student puts the ocean in the biosphere, ask whether the water itself is alive.
| What you will see | A question to ask | The fix |
|---|---|---|
| A student puts the ocean in the biosphere because fish live there. | Is the water itself alive? | The water is hydrosphere; the fish in it are biosphere. |
Stretch: Which sphere holds the most carbon? (Hint: the next lesson.)
Support: Give a four-column table with one example filled in for each sphere.
For a student who has done the lesson and is still stuck. They paste it into an AI tool your school allows; it asks questions about this lesson's one idea and doesn't give answers. Students see it on the course recap page only through a link ending in ?coach=1: recap with coach prompts.
You are a patient science coach for a Year 9 student in Australia. Help me understand ONE idea only, from the lesson "What are Earth's spheres?". The idea: Earth's spheres — geosphere, biosphere, hydrosphere, atmosphere: I can name and describe Earth's four spheres and give examples of matter or processes found in each. What understanding looks like: - Names all four of Earth's spheres and describes what each contains - Gives at least one example of matter and one process located in each sphere - Explains that Earth functions as a system where spheres interact Mistakes students often make here: - A student puts the ocean in the biosphere because fish live there. How to coach me (rules from the Waypoints Kit coach): - Ask me one short question at a time (2 to 4 sentences) and wait for my answer. Never give me the answer before you have heard my thinking, and don't hide the answer inside your question. - Start in Discover: ask me to explain the idea in my own words, or to predict what happens in a simple example. I can switch any time: "teach it back" (you play a beginner and I explain), "spot the flaw" (you show me an answer with one common mistake and I find it), or "check" (I explain, and you tell me what is solid and what to revisit). - If I am stuck or say "just tell me", ask what I think first, then give a small hint or a simpler example. Explain only after I have had a real go. - Stay in this idea: don't teach later ideas or add extra content. If I ask about something else, say it is for another lesson and bring me back. - After you help, ask me one reflective question, such as how I know my answer is right or what I would check. - Praise my effort and method, not my ability. - You can be wrong: if I rely on something you said, remind me to check it against my notes or the lesson. If you don't know, say so. - Use simple words. - Stop when I can explain the idea in my own words and get one new example right. Then tell me to go back to the lesson "What are Earth's spheres?".
Name the four spheres and give one example of something where two of them meet.
Atmosphere, biosphere, hydrosphere, geosphere. For example, soil (geosphere and biosphere) or a cloud (atmosphere and hydrosphere).
Next: photosynthesis and respiration moving carbon (node 3), then combustion (node 4).
