Curriculum Framework

6 lessons

Compare, test, and group everyday materials based on hardness, transparency, magnetism, and flexibility.

5 lessons

Test, compare, and explain thermal and electrical conductivity in everyday materials.

5 lessons

Investigate how substances dissolve in liquids to form solutions and explore factors affecting dissolving rates.

7 lessons

Choose and use appropriate scientific techniques such as sieving, filtering, magnetic separation, and evaporation to separate mixtures.

5 lessons

Give reasons based on evidence from fair tests for why particular materials are chosen for specific products.

5 lessons

Demonstrate that changes of state, dissolving, and physical mixing are reversible changes.

6 lessons

Explain that irreversible changes produce new materials with new properties and identify examples such as burning, rusting, and acid reactions.
