Physical changes in Year 7 Science
Start here
Focus on explaining changes of state and diffusion. Open support for “Describe and Explain Diffusion”, then explain the idea in your own words.
Year 7 learners practise explaining changes of state and diffusion.
The activities include Describe and Explain Diffusion, Describe Changes of State, Explain Brownian Motion, and related practice. The checked support below includes teach, video, teaching, worksheet. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
