Washington Comprehensive Assessment of Science (WCAS) Grade 5 study plan

Washington Comprehensive Assessment of Science (WCAS) Grade 5 · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Earth and Space Sciences

  • Identify and describe the four major Earth systems (geosphere, hydrosphere, atmosphere, biosphere) and give one example of matter or energy moving between each pair.

  • Explain how the Sun's energy drives the water cycle, and trace a water molecule through evaporation, condensation, precipitation, and collection.

  • Distinguish between weather and climate, and list at least three factors that influence climate in a region.

  • Interpret a simple weather map or data table to describe temperature, precipitation, and wind patterns.

Your checkpoint

Create a labeled diagram of the water cycle with a written explanation (5–7 sentences) of how the Sun powers it.

Week 2

Earth and Space Sciences

  • Compare renewable and nonrenewable energy resources and classify at least six examples correctly.

  • Describe how human activities can affect the four Earth systems, and propose one solution to reduce a negative impact.

  • Explain the processes of erosion, deposition, and weathering, and identify landforms created by each.

  • Read and interpret a simple geologic column or rock layer diagram to infer relative ages.

Your checkpoint

Write a one-page argument (with evidence) for using one renewable energy source in a specific community, addressing at least one trade-off.

Week 3

Earth and Space Sciences & Physical Sciences

  • Describe the layers of Earth (crust, mantle, outer core, inner core) and compare their relative thickness and composition.

  • Explain plate tectonics and relate plate boundaries to earthquakes, volcanoes, and mountain building.

  • Define matter, mass, and volume, and use these terms to describe common materials.

  • Measure and record mass and volume using appropriate tools (balance, graduated cylinder), and calculate density with a simple formula.

Your checkpoint

Complete a lab report that measures the mass and volume of three objects and calculates their densities, with a conclusion about whether they sink or float.

Week 4

Physical Sciences

  • Classify matter as solid, liquid, or gas based on particle arrangement and motion, and describe changes of state in terms of energy.

  • Distinguish between physical and chemical changes, and provide two examples of each with evidence.

  • Identify the parts of an atom (proton, neutron, electron) and explain how elements are organized on the periodic table.

  • Use the periodic table to identify properties of common elements and predict whether a material is a metal, nonmetal, or metalloid.

Your checkpoint

Create a concept map linking matter, states of matter, physical/chemical changes, and atoms, with at least 10 correctly labeled connections.

Week 5

Physical Sciences & Life Sciences

  • Explain how energy is transferred through conduction, convection, and radiation, and give a real-world example of each.

  • Describe how light and sound travel in waves, and compare their properties (wavelength, frequency, amplitude).

  • Trace the flow of energy through a simple food chain and explain the roles of producers, consumers, and decomposers.

  • Describe how plants use sunlight to make food (photosynthesis) and how animals obtain energy from food.

Your checkpoint

Design and explain a simple circuit or energy transfer device that demonstrates at least two types of energy transfer, with a written explanation.

Week 6

Life Sciences

  • Compare the structures and functions of plant and animal cells, and identify at least four organelles and their jobs.

  • Explain how body systems (e.g., circulatory, respiratory, digestive) work together to support life processes.

  • Describe inherited traits versus learned behaviors, and give examples of each in plants and animals.

  • Model how organisms interact in an ecosystem, including competition, predation, and mutualism.

Your checkpoint

Create a 3-D model or detailed diagram of a plant or animal cell with a key that explains the function of at least five organelles.

Week 7

Life Sciences & Earth and Space Sciences

  • Explain how adaptations help organisms survive in their environments, and give examples from at least three biomes.

  • Describe the stages of a life cycle for a plant and an animal, and compare their reproductive strategies.

  • Analyze how changes in an environment (e.g., drought, fire, human development) can affect populations and ecosystems.

  • Interpret a graph of population data to predict future trends and identify possible causes.

Your checkpoint

Write a short research summary (1 page) on how one specific organism is adapted to its environment, citing at least two sources.

Week 8

Physical Sciences & Life Sciences & Earth and Space Sciences

  • Integrate concepts from physical, life, and Earth sciences to explain a real-world phenomenon (e.g., how a volcanic eruption affects climate and ecosystems).

  • Practice answering multiple-choice and short-constructed-response questions under timed conditions, and review errors.

  • Use evidence to construct a scientific explanation that includes a claim, evidence, and reasoning.

  • Review and self-assess mastery of all key vocabulary and core ideas from the 8 weeks.

Your checkpoint

Complete a full-length practice test (or a set of 30 mixed questions) with at least 80% accuracy, and write a reflection on three areas for further review.

Milestones

Week 2: Score at least 80% on a 10-question quiz covering Earth systems, water cycle, and renewable/nonrenewable resources.

Week 4: Successfully calculate density for three objects and correctly classify five physical/chemical changes with 100% accuracy.

Week 6: Explain the flow of energy from the Sun to a top predator in a food chain, and identify at least three cell organelles and their functions.

Week 8: Achieve at least 80% on the final mixed practice test and submit a reflection identifying three specific topics to review before the exam.
