8th Grade Science FCAT 2.0 Review Notes

Purpose of the Presentation

  • Review material required for the Science FCAT 2.0

  • Cover all assessed benchmarks from 6th-8th grade

  • Use for whole class, small group, or individualized assessment

Main Topics Covered

  • Nature of Science (Slides 4-26)

  • Earth Science (Slides 27-69)

  • Physical Science (Slides 70-113)

  • Life Science (Slides 114-150)

Key Benchmarks in Science

  • SC.8.N.1.1: Evaluate scientific investigations and analyze data.

  • SC.7.N.1.3: Distinguish between experiments and other investigations.

  • SC.7.N.1.4: Identify independent and dependent variables.

  • SC.8.N.1.4: Explain the importance of hypotheses.

Importance of Hypotheses

  • Crucial for guiding experimental design and predicting outcomes (SC.8.N.1.4).

Scientific Experimentation Concepts

  • Replication vs. Repetition:

    • Replication: Conducting the same experiment by different scientists to verify results.

    • Repetition: Performing the same experiment multiple times to ensure reliability.

Evidence and Conclusions Example

  • Data comparison from trials of various objects traveling down a ramp to support hypotheses.

Distinguishing Experiments & Investigations

  • Example: Melanie conducts an experiment on bat types while Brody does research (SC.7.N.1.3).

Understanding Variables

  • Test (dependent) variable and outcome (independent) variable in scientific investigations (SC.7.N.1.4).

Scientific Knowledge Evolution

  • Knowledge changes with new evidence (SC.6.N.2.2). Example: Theory of Plate Tectonics based on observed data.

Classifications in Science

  • Differentiate between theories (explain phenomena) and laws (describe effects) (SC.7.N.3.1).

Earth Science Topics

  • Compare astronomical bodies (size, distance, and composition) (SC.8.E.5.3).

  • Understand solar system mechanics and gravity's role in forming celestial bodies (SC.8.E.5.4).

Life Science Topics

  • Hierarchical organization of life (cells, tissues, organs, systems).

  • Understand cellular processes and homeostasis (SC.6.L.14.3).

Energy and Matter

  • Conservation Laws: Energy and mass are conserved in chemical and physical processes (SC.8.L.18.4).

  • Functions of photosynthesis and respiration in energy transfer (SC.8.L.18.1, SC.8.L.18.2).

Concluding Remarks

  • Presentation meant for review and not as a substitute for formal teaching.
