Life Science:
* Cells: Structure and function of cells (plant vs. animal cells), cell processes like respiration and photosynthesis.
* Genetics: Basic inheritance, traits, DNA, and possibly Punnett squares.
* Evolution: Natural selection, adaptation, and evidence for evolution.
* Ecology: Ecosystems, food chains and webs, populations, and interactions within ecosystems (predation, competition, symbiosis). Human impact on the environment is often included.
* Human Body Systems: Often focuses on one or two systems in more detail, such as the digestive, circulatory, or respiratory systems.
Physical Science:
* Motion and Forces: Newton's laws of motion, gravity, speed, velocity, acceleration, forces and their interactions.
* Energy: Forms of energy (kinetic, potential, chemical, etc.), energy transformations, and conservation of energy.
* Waves: Properties of waves (wavelength, frequency, amplitude), sound waves, and light waves.
* Matter: States of matter, physical and chemical changes, properties of matter.
Earth and Space Science:
* Plate Tectonics: Earth's structure, plate boundaries, earthquakes, volcanoes, and mountain formation.
* Weather and Climate: Weather patterns, climate zones, and the water cycle.
* Astronomy: Solar system, stars, galaxies, and the universe.
Overall Themes:
* Scientific Method: Designing experiments, collecting data, analyzing results, and drawing conclusions.
* Data Analysis: Interpreting graphs, charts, and tables.
* Technological Applications: Connections between science concepts and technology.
It's important to note that this is a general overview. Some seventh-grade science classes might delve deeper into specific topics, while others might offer a broader, more introductory approach. A good way to know the specifics is to check the school's curriculum or syllabus.
