Science · Grade 3

Forces & life cycles

Measure forces, study life cycles and track weather data.

Grade4
Science · Grade 4

Energy & Earth

Build circuits, study waves and read the rock record.

01

Understand the pathway

What this year covers

Fourth graders study energy, waves and Earth’s history in rocks. Accelerated students build circuits, join elementary Science Olympiad teams and use PhET simulations.

  • Energy transfer
  • Electric circuits
  • Waves & information
  • Rocks, fossils & erosion
  • Plant & animal structures
  • Natural hazards

Next stopReady for grade 5 when a circuit can be designed to solve a problem and explained with an energy diagram.

Grade5
Science · Grade 5

Matter, ecosystems & space

Model particles, food webs and the solar system.

01

Understand the pathway

What this year covers

Fifth grade connects matter, ecosystems, Earth’s systems and space. It is the first year for the 3M Young Scientist Challenge, and a strong year to preview middle school science.

  • Particles of matter
  • Food webs
  • Earth’s spheres
  • Water on Earth
  • Gravity
  • Stars & the solar system

Next stopReady for middle school honors science when a model can be used to explain matter and energy in an ecosystem.

Middle school · Grades 6–8

Quantitative middle school science, Science Olympiad and Science Bowl teams.

Grade6
Science · Grade 6

Integrated science 6+

Study cells, Earth and energy, and join a Science Olympiad team.

01

Understand the pathway

What this year covers

Middle school science gets quantitative. Sixth graders study cells, Earth’s systems and energy, and can join Science Olympiad Division B and National Science Bowl teams.

  • Cells & organisms
  • Earth’s interior & plate tectonics
  • Weather systems
  • Energy & heat
  • Engineering design
  • Lab safety & measurement

Next stopReady for honors life science when a controlled experiment is designed and written up as a lab report.

Grade7
Science · Grade 7

Honors life science

Go deep on cells, genetics and evolution.

01

Understand the pathway

What this year covers

Honors life science covers cells, genetics, evolution and ecosystems at depth, preparing students to take Honors Biology early.

  • Cell structure & function
  • Genetics & heredity
  • Evolution & natural selection
  • Human body systems
  • Ecosystems
  • Scientific argumentation

Next stopReady for physical science with algebra when genetics problems (Punnett squares) and data analysis are solid.

Grade8
Science · Grade 8

Physical science with algebra

Use algebra to describe motion, forces, energy and chemical reactions.

01

Understand the pathway

What this year covers

Accelerated eighth graders pair physical science with their Algebra 1 course: motion graphs, Newton’s laws, the periodic table and chemical reactions. This prepares them for Honors Biology and Chemistry.

  • Motion & graphs
  • Newton’s laws
  • Energy & work
  • Atoms & the periodic table
  • Chemical reactions
  • Waves & electromagnetism

Next stopReady for Honors Biology when motion and energy problems can be solved algebraically.

High school · Grades 9–12

Honors Biology and Chemistry, AP sciences, olympiads and original research.

Grade9
Science · Grade 9

Honors Biology

Take high school biology and start olympiad and research tracks.

01

Understand the pathway

What this year covers

Honors Biology covers biochemistry, cells, genetics, evolution and ecology with real lab work. Strong students start USABO preparation and science fair research.

  • Biochemistry
  • Cell biology
  • Molecular genetics
  • Evolution
  • Ecology
  • Experimental design

Next stopReady for Honors Chemistry with an A in Honors Biology and Algebra 1 complete.

Grade10
Science · Grade 10

Honors Chemistry

Master chemistry fundamentals and try the Chemistry Olympiad.

01

Understand the pathway

What this year covers

Honors Chemistry uses algebra heavily: stoichiometry, gas laws, equilibrium and acid–base chemistry. It is the base for AP Chemistry and the U.S. National Chemistry Olympiad.

  • Atomic structure
  • Bonding
  • Stoichiometry
  • Gas laws
  • Equilibrium
  • Acids & bases

Next stopReady for AP science when chemistry problems combine several concepts without step-by-step prompts.

Grade11
Science · Grade 11

AP Biology or AP Physics 1

Take a first AP science and aim for olympiads and research programs.

01

Understand the pathway

What this year covers

Eleventh graders take AP Biology or AP Physics 1, often both over two years. This is the prime year for the F=ma exam, USABO, and summer research programs.

  • Kinematics & dynamics
  • Energy & momentum
  • Rotation
  • Molecular biology
  • Cell signaling
  • Statistics for lab data

Next stopReady for AP Chemistry or AP Physics C with a 4 or 5 on the AP exam.

Grade12
Science · Grade 12

AP Chemistry / AP Physics C + research
