United States 11th Grade (Junior Year) High School Subjects - Science

This outlines typical science subjects covered in the 11th grade in US high schools. Common choices include Physics, Chemistry, and Biology, often with more specialized topics within each subject.

Physics

11th-grade physics often covers the fundamentals of classical mechanics, electricity and magnetism, thermodynamics, and optics, sometimes including an introduction to modern physics. Specific topics can vary, but common themes include:

• Mechanics: Kinematics (motion), dynamics (forces), work, energy, power, and rotational motion. Some curricula may include fluid dynamics.
• Electricity and Magnetism: Electric charges, fields, potential, capacitance, current, circuits, and magnetic fields.
• Waves and Thermodynamics: Wave properties, sound, heat, temperature, and the laws of thermodynamics.
• Modern Physics: Introductions to topics like relativity and quantum mechanics may be included.

Specific examples of topics covered in 11th-grade physics include: motion in a straight line, rotational motion dynamics, and work, energy, and power. Another resource lists kinematics, dynamics, waves and thermodynamics, and electricity and magnetism as core modules.

Chemistry

11th-grade chemistry typically covers a range of topics, including:

• Basic Concepts: Measurement, atomic structure, chemical bonding, and stoichiometry.
• Inorganic Chemistry: Periodic trends, properties of matter, chemical reactions, solutions, acids and bases, and gas laws.
• Organic Chemistry: Introduction to organic compounds and their reactions. This may be a more in-depth study depending on the curriculum.
• Physical Chemistry: Thermochemistry, thermodynamics, and equilibrium. Some curricula may include electrochemistry and nuclear chemistry.

A common starting point is chemical bonds, including ionic and covalent bonds, intermolecular forces, and Lewis structures. Other important topics include atomic structure and periodic trends, chemical bonding, properties of matter, and chemical reactions.

Biology

11th-grade biology often focuses on cell biology, genetics, evolution, and ecology. Specific topics can include:

• Cell Biology: Cell structure and function, cellular respiration, photosynthesis, and cell division.
• Genetics: Mendelian genetics, molecular genetics, and genetic engineering.
• Evolution: Natural selection, speciation, and the history of life.
• Ecology: Ecosystems, populations, and communities.

Some curricula may also include botany, zoology, biochemistry, physiology, taxonomy, and anatomy. Other resources list topics such as the living world, biological classification, plant and animal kingdoms, morphology and anatomy of flowering plants, and structural organization in animals.
