Science Volume 3 | Lessons 19–28 | All-Age Advanced Pathways
OPEN OR DOWNLOAD PRINTABLE PDF: Science Volume 3 Student Workbook. The complete lesson or guide text remains copyable below. Student and parent materials are separated to support independent work.
Ten additional instructional lessons in physical science, Earth science, life science and inquiry. Each includes direct teaching and three readiness routes. Younger advanced learners can work in any route they demonstrate readiness for, with appropriate supervision and oral responses. Never claim hypothetical data are real results. Use approved safety procedures and credible science sources.
Teaching cycle: read, explain vocabulary, model the concept, complete appropriate tasks, correct errors and discuss limits of what observations prove. Copy questions into a notebook or print this webpage.
Lesson 19: Forces, Motion and Measurement
Teach: A force is a push or pull. A moving toy’s speed depends on distance traveled over time. A controlled comparison changes one planned factor, measures an outcome and holds other conditions alike.
Early Advanced
- Push a toy gently with an adult on a safe surface. Draw its position before and after.
- Name what moved and state whether you observed or guessed its distance.
- Measure one distance with a ruler if safe.
Developing Advanced
- Design a fair test comparing a toy’s movement on two surfaces.
- State the independent variable and measured distance in centimeters.
- Use invented practice values 40,50,45 cm to find mean.
Extended Advanced
- Explain how surface, initial push and vehicle mass could confound distance comparison.
- Describe three controlled variables and a repeatable launch method.
- Write a proposed methods paragraph with uncertainty and no fabricated data.

Lesson 20: Matter and States
Teach: Matter has mass and occupies space. Solids hold shape more readily, liquids flow and take container shape, gases expand to fill available space. Heating and cooling can change state, but properties vary by material.
Early Advanced
- Name one solid, liquid and gas in everyday life.
- Draw ice and liquid water; explain which can flow.
- Explain why containers are necessary to hold liquids.
Developing Advanced
- Distinguish melting, freezing, evaporation and condensation.
- Write a short account of a water droplet’s possible state changes without inventing measurements.
- Classify five materials by observable state at room temperature.
Extended Advanced
- Explain particle models for solids, liquids and gases without saying particles themselves melt.
- Identify energy transfer in melting and evaporation.
- Evaluate why boiling point depends on pressure and other conditions.

Lesson 21: Energy Transfer and Conservation
Teach: Energy can move or transform between forms. A lamp converts electrical energy partly to light and thermal energy. It is inaccurate to say the lamp creates energy from nothing.
Early Advanced
- Describe where light from a lamp goes.
- Name one reason to turn lights off when not needed.
- Draw two safe objects that give off light.
Developing Advanced
- Make a labeled energy-flow diagram for an electric fan.
- Describe why a phone may warm while charging.
- Give one example of wasted but conserved energy as heat.
Extended Advanced
- Distinguish energy conservation from useful-energy efficiency.
- Explain how electrical power relates to energy use over time.
- Create a hypothetical energy budget using watts and hours, clearly labeling invented figures.

Lesson 22: Weather Maps and Forecast Uncertainty
Teach: Weather observations include air temperature, wind, humidity and precipitation. Forecasts are predictions based on models and data; they are uncertain, especially farther into the future.
Early Advanced
- With a caregiver, draw a sun, cloud and rain symbol.
- Describe today’s weather without assuming tomorrow will match.
- Name a safe place to shelter during dangerous weather.
Developing Advanced
- Read a verified forecast map with adult guidance and identify symbols.
- Keep a five-day table of observed weather and label the date.
- Explain why one day does not describe a region’s climate.
Extended Advanced
- Compare two credible forecast outlooks for the same date and area.
- Describe probabilities and their interpretation without promising specific outcomes.
- Explain why model assumptions and measurement limitations matter.

Lesson 23: Water Systems and the Water Cycle
Teach: Water changes location and state through evaporation, condensation, precipitation and runoff. The water cycle involves energy from the sun and gravity. Local water systems include watersheds and groundwater.
Early Advanced
- Draw water falling as rain and collecting in a stream.
- Point to a cloud and puddle in a picture.
- Explain why clean drinking water matters.
Developing Advanced
- Draw and label evaporation, condensation and precipitation.
- Explain one way rain reaches a river.
- Distinguish runoff from infiltration using correct language.
Extended Advanced
- Explain how land cover changes infiltration and runoff.
- Design a safe model comparing water through two soil materials without contaminating drinking water.
- Cite a credible scientific reference for a watershed claim.

Lesson 24: Cells and Living Systems
Teach: Cells are basic structural and functional units of living organisms. Many organisms are single-celled; others consist of many specialized cells. Plant and animal cells share structures while differing in some components.
Early Advanced
- Draw a plant and identify that it is living.
- Name two needs of living things.
- Explain why a rock is not normally considered a living organism.
Developing Advanced
- Label membrane, cytoplasm and nucleus on a simplified cell drawing.
- Describe one difference between a typical plant and animal cell.
- Explain how cells form tissues in multicellular organisms.
Extended Advanced
- Describe function of membrane and mitochondrion with appropriate scope.
- Explain how specialized cells support tissue function.
- Describe why not every living cell contains a nucleus.

Lesson 25: Human Body Systems and Evidence
Teach: Circulatory, respiratory, digestive and skeletal systems have distinct but interacting functions. Health advice should rely on evidence, and individual medical needs require qualified care.
Early Advanced
- Locate heart, lungs and stomach in a simple diagram.
- Name one safe habit supporting general wellbeing.
- Explain why bodies need sleep.
Developing Advanced
- Compare breathing and circulation.
- Describe a route by which nutrients can reach cells after digestion.
- Identify two roles of bones.
Extended Advanced
- Explain how gas exchange supports cellular function.
- Describe evidence limitations in a popular health claim.
- Cite a credible medical or educational source without diagnosing anyone.

Early Advanced
- Draw two different plants or animals in their environments.
- Identify food, shelter and water needs.
- Explain why you should not disturb unfamiliar nests.
Developing Advanced
- Construct a food web with producer, consumer and decomposer.

- Distinguish abundance from species richness.
- Explain how habitat fragmentation might affect populations using cautious causal language.

Lesson 27: Scientific Argument with Data
Teach: A scientific conclusion should connect a claim to evidence and reasoning. Raw observations and modeled interpretations are different. Independent replicability strengthens, but does not guarantee, confidence.
Early Advanced

- Tell a trusted adult a question you still have.
- Draw and label one measurement tool.
Developing Advanced
- For fictional measurements 3,5,7,9,11, compute mean and range.

Extended Advanced
- For fictional measurements 2,4,4,5,15, compare median and mean.
- Analyze outlier effects and identify two alternative explanations.
- Write a 200-word evidence-based argument with an uncertainty statement.

Cumulative Assessment
Lesson 28 is an independent check. Use fresh examples and safe research. Assess science concepts separately from handwriting. A completed volume does not establish complete yearly science standards mastery.
