Physical changes in Year 7 Science
Start here
Focus on changes of state and diffusion explained. Start with “Describe and Explain Diffusion”, then explain the idea in your own words.
Year 7 learners practise changes of state and diffusion explained.
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.
Activities covered
- Describe and Explain Diffusion
- Describe Changes of State
- Explain Brownian Motion
- Explain Changes of State
- Explain the Changes of State of Water
- Study the Similarities and Differences Between Solids, Liquids, and Gases
- Understand Changes of State Between Solids, Liquids and Gases
