1. Cell biology: animal cell structure labeling, plant-only structures (chloroplast, cell wall), mitochondria function (energy release from respiration) 2. Particle models: identification of element, compound, mixture; alloy definition; drawing particle model of mercury as a liquid 3. Energy transfer: types of energy during activity (sound, thermal), energy dissipation explanation 4. Earth science: events near plate boundaries (earthquakes, volcanoes, mountain formation), layers of Earth (crust, mantle), convection flow movement 5. Specialized cells: root hair cell function (absorption), surface area and structure adaptation 6. Gas tests: oxygen (glowing splint), carbon dioxide (limewater), hydrogen (squeaky pop) 7. Sound: air particle movement in sound transmission, absence of sound in vacuum due to lack of particles
