  1. 01

    Motion, forces, and graph evidence

    80 checks
    • Use position, speed, velocity, acceleration, and force correctly.
    • Read motion graphs and connect slope to meaning.

    Practice: Analyze a motion graph and write what the object is doing in each interval.

  2. 02

    Energy, waves, and transfers

    80 checks
    • Track kinetic, potential, thermal, sound, and light energy transfers.
    • Describe wave properties and interactions.

    Practice: Build an energy-transfer diagram for one everyday system and label evidence for each transfer.

  3. 03

    Earth systems, rocks, and geologic change

    80 checks
    • Model the geosphere, hydrosphere, atmosphere, and biosphere as interacting systems.
    • Explain rocks, plate motion, erosion, and geologic time with evidence.

    Practice: Create a systems diagram for one Earth process and annotate cause-effect arrows.

  4. 04

    Weather, climate, and human impact

    80 checks
    • Use atmosphere, water cycle, ocean, and climate data to explain patterns.
    • Separate weather observations from climate trends.

    Practice: Compare two weather or climate data displays and write a claim with one limitation.
