Topic title: Kitchen Chemistry
Year group: 7
When taught: Autumn term 2
Overview: Term 2 takes the experimental skills learnt in term 1 and combines them with the study of the key foundations of chemistry and physics in “Kitchen Chemistry”. Areas studied include the particle model, changes of state and signs of a reaction. Pupils are encouraged to continue refining their data collecting and analysing of results as well as best working practice in the lab.
What the students targets for this topic?
| I know what the 3 states of matter are |
| I can describe the properties of solids, liquids, and gases |
| I can draw the arrangement of the particles in each state of matter |
| I can describe what density is |
| I can label the state changes on a diagram |
| I can describe what happens to the particles when state changes occur in terms of energy |
| I can describe what elements and compounds are |
| I can describe the particle arrangement in a mixture |
| I can explain how to identify a pure substance |
| I know the meaning of the key “sol” words, (solvent, solute, solution, soluble) |
| I can describe how particles can move from one area to another |
| I can identify some real-life situations where filtration is used |
| I can describe the process of evaporation |
| I know what distillation is |
| I can describe the difference between a chemical and a physical change |
Why is this important to know?
- This topic will help students understand the universe around them and the properties and structures of matter.
- This topic will help students develop laboratory skills by completing some practical tasks, as well as designing investigations to test ideas that they have learned and apply them to the real world.
- This topic will introduce key terms in science which will be built upon in KS4.
Where does this link into our past and future learning?
- This topic has links to the KS2 principles in States of matter, Properties and Changes of Materials, and develop them further by introducing a scientific model as to why physical phenomena are observed.
- This topic will use investigative approaches learned in earlier topics and key stages and apply them to investigations.
- The knowledge and skills learned in this topic are the foundations for key principles in the big ideas in year 9 and then into KS4 Science and Design and Technology.
How will we be assessed on this topic?
- There will be an end of unit test in class to formally assess the skills developed. There will be online homework quizzes to help students practice their skills.
What makes a strong piece of work in this topic? What are teachers hoping to see?
- Attention to detail.
- Independent construction of appropriate results tables (including measure, units, and in the appropriate order).
- Independent drawing of appropriate graphs from data given.
- Numbered lists for experimental methods.
- Appropriate observations of results recorded.
What key words are there in this topic?
What can I try if I want to stretch and challenge myself on this topic?
- Research and understand more exotic states of matter where different rules exist – plasma, non-Newtonian fluids, foams, gels, sols, and nanoparticles.
- Research how elements are made in stars.
- Research examples of useful mixtures (formulations)
