BIG IDEA
Understand the idea before memorising a rule.
Energy and heat is part of space. At Grade 7, the goal is to connect this topic to a clear method, relevant evidence and a final check. You will apply that idea to a real space question at this grade level.
YOU WILL LEARN TO
- Explain the key ideas in energy and heat using accurate science vocabulary.
- Apply a reliable method to a new energy and heat task.
- Check the result and explain why the evidence supports it.
METHOD
A reliable three-step approach
- 1
State the scientific idea using accurate vocabulary.
- 2
Connect cause and effect with an observation or model.
- 3
Check the explanation against evidence, units and safety rules.
WORKED EXAMPLE
During a class warm-up for Grade 7, what keeps planets moving around the Sun?
Model response
The correct answer is Gravity. The Sun's gravitational attraction continually bends each planet's path into an orbit.
