Elements, compounds and mixtures

BIG IDEA

Understand the idea before memorising a rule.

Elements, compounds and mixtures is part of physics. 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 physics question at this grade level.

YOU WILL LEARN TO

• Explain the key ideas in elements, compounds and mixtures using accurate science vocabulary.
• Apply a reliable method to a new elements, compounds and mixtures task.
• Check the result and explain why the evidence supports it.

METHOD

A reliable three-step approach

1. 1

   State the scientific idea using accurate vocabulary.

2. 2

   Connect cause and effect with an observation or model.

3. 3

   Check the explanation against evidence, units and safety rules.
