2. Carbon cycle processes (photosynthesis, respiration, decomposition), displacement reactions and reactivity series explanation, anomalous data identification and graph drawing
3. Waveform analysis (amplitude, frequency, volume), fossil distribution as evidence for continental drift, water transport in plants (root hair to leaf to stoma pathway)
4. Group 1 element trends (melting/boiling point), parallel vs. series circuit construction and brightness comparison, nebulae formation and function
5. Natural selection stages and adaptation advantage, reaction rate vs. temperature, prediction using particle model, wave interference outcome
6. Climate change impacts, density and floating materials, sea water density estimation, displaced volume measurement from floating object
