Trace water and matter through Earth's four connected systems with precise definitions, an answer key, and a model-building activity for Grade 5.
For parents and caregivers
What your child will practice
- Identify the geosphere, hydrosphere, atmosphere, and biosphere as interacting Earth systems.
- Trace water through evaporation, condensation, precipitation, runoff, and infiltration.
- Use a system model to explain how water and matter move between reservoirs.
How to use this puzzle at home
- Read the four sphere definitions first and invite your child to name one familiar example from each Earth system.
- Solve the puzzle, checking each found term against its definition instead of using the answer key right away.
- Trace one raindrop from a cloud to the ground, through soil or a stream, and back to the atmosphere.
- Finish with the answer key and ask your child to connect at least three vocabulary words in one cause-and-effect sentence.

Vocabulary guide
Use these short definitions before or after the word search. Ask your child to explain a few in their own words.
- Geosphere
- The solid parts of Earth, including rocks, soil, landforms, and the planet's interior.
- Hydrosphere
- All of Earth's water in liquid, solid, and gaseous forms.
- Atmosphere
- The mixture of gases surrounding Earth where weather and clouds form.
- Biosphere
- All living things on Earth and the places where they live.
- System
- A group of connected parts that interact and work together as a whole.
- Interaction
- A relationship in which parts of a system affect one another.
- Reservoir
- A place where water or another material is stored within a system.
- Precipitation
- Water that falls from clouds as rain, snow, sleet, or hail.
- Evaporation
- The change of liquid water into water vapor, usually after gaining heat energy.
- Condensation
- The change of water vapor into liquid droplets as the vapor cools.
- Transpiration
- The release of water vapor from small openings in plant leaves.
- Runoff
- Water that flows over land into streams, lakes, and oceans.
- Infiltration
- The process of water soaking from the land surface into soil and rock.
- Groundwater
- Water stored underground in spaces and cracks within soil and rock.
- Weathering
- The breaking down of rock at or near Earth's surface.
- Erosion
- The movement of weathered rock or soil by water, wind, ice, or gravity.
Talk about the science
- How can one raindrop move through all four of Earth's major systems?
- What conditions cause water vapor to condense into cloud droplets?
- How can runoff both shape the geosphere and carry materials into the hydrosphere?

Extension activity
Build a closed water-cycle model in a clear container with damp soil and a small plant. Observe it over several days, label evidence of storage and movement, and explain which Earth systems are interacting at each step.
Teacher and tutor note
Classroom adaptation
Assign each group one Earth system and have students make labeled cards for its materials and processes. Combine the cards on a wall model, then add arrows that show interactions such as rain weathering rock or plants releasing water vapor.
