Units
All 6 units of Science 10. Each one has a concepts page to learn from, practice questions marked as you go, and quizzes built at random.
Unit 1
Unit 1: Atoms, elements and the periodic table
Where the periodic table's shape comes from, and why an element's place on it predicts almost everything it does.
Unit 2
Unit 2: Compounds, names and chemical equations
Ionic and molecular compounds, the naming system, balancing equations, and the law that makes balancing necessary in the first place.
Unit 3
Unit 3: Energy, work, power and efficiency
Energy can be counted. Work is a transfer of it, power is the rate, and efficiency is the honest accounting of what you got for what you put in.
Unit 4
Unit 4: Heat and thermal energy
Temperature is not heat, and the difference matters. Conduction, convection and radiation, specific heat capacity, and the two laws of thermodynamics.
Unit 5
Unit 5: Cells and the cycling of matter
The cell as an open system: what each organelle does, how things cross a membrane, and the two processes that move carbon and energy through every living thing.
