Water Properties
This picture book treats water as a surprising, active substance. It opens by naming three special powers, cohesion, adhesion, and the universal solvent, and then uses small, vivid examples to make each idea visible: beads of rain clinging to a window, a water strider standing on a pond, a flower stem pulling colored water upward, and sweat cooling the body. Later pages move outward to the water cycle, the reason ice floats, a few startling water facts, and a short glossary.
About the Book
This picture book treats water as a surprising, active substance. It opens by naming three special powers—cohesion, adhesion, and the universal solvent—and then uses small, vivid examples to make each idea visible: beads of rain clinging to a window, a water strider standing on a pond, a flower stem pulling colored water upward, and sweat cooling the body. Later pages move outward to the water cycle, the reason ice floats, a few startling water facts, and a short glossary.
Prerequisite Requirements
No formal science vocabulary or special preparation is needed. A child who has seen raindrops on a window, dipped a finger into water, or watched ice float in a drink already has the everyday experience this book builds from. A grown-up or older reader can simply read each double-page spread slowly, letting the illustrations carry the ideas.
Learning Benefits
The book turns familiar moments—beads on glass, plants drinking, sweat cooling, ice floating—into short scientific explanations, so children can connect new words to things they can actually notice and test. It offers shared-reading chances to trace a diagram, predict page, ask “what if?”, and try a simple observation such as dipping a paper towel in water.
Structured Knowledge Path
This book is an entry point to physical science and Earth-science ideas that are usually studied later: states of matter, mixtures and dissolving, capillary movement, heat and evaporation, and density. It starts with water’s surface-level properties and then follows the same concepts outward to bodies, plant stems, clouds, and frozen ponds.
Advancement
Later learning can take each of these drops and deepen it. The universal solvent idea leads to solutions, concentration, and pH; the floating-ice observation leads to density and buoyancy; the evaporation and condensation lines lead to weather and heat transfer; the plant-stem example can connect to water uptake and photosynthesis. The book’s open question—What if water did not stick together?—is also a ready-made launchpad for simple scientific predictions.
Knowledge Points
- Water molecules pull toward one another, which makes drops pull themselves into round beads instead of flattening out.
- The same stickiness between water molecules creates a skinlike surface that insects can stand on.
- Water can cling to other materials and climb upward through narrow spaces, which is how petals get colored water.
- Water’s power to dissolve many things helps it carry sugar, salt, and nutrients wherever it goes.
- Water helps the body cooler because sweat leaning carries heat away as water evaporates from the skin.
- Unlike most substances, water expands when it freezes, so ice floats and keeps the water underneath liquid for fish.

Vocabulary
- Cohesion
- The tendency of water molecules to stick to one another, which makes droplets take rounded beads.
- Surface tension
- The stretchy “skin” on the top of water that forms because water molecules pull on each other; it lets some insects rest on the surface.
- Adhesion
- The tendency of water to stick to other materials, such as your skin or the tiny tubes inside a plant stem.
- Capillary action
- Water’s ability to rise and move through narrow spaces, such as the inside of a flower stem or a paper towel.
- Universal solvent
- Water’s ability to dissolve a great many substances, which helps it carry nutrients, sugar, and ocean salts.
- Evaporation
- The process of liquid water changing into a gas and rising into the air.
- Condensation
- The process of water vapor cooling to form liquid droplets, such as cloud water.
- Precipitation
- Water falling from clouds through the air as rain, snow, or hail.
Reading Guidance for Teachers and Guardians
- Page 5: Pause at the beaded drops on the window and ask the child whether the water looks like a circle or like a flat puddle; let them try a own sprinkle of water on a tray.
- Page 6: Ask the child to find the water strider and tell you why the surface of the water might look like the stretched skin before you read the word.
- Page 8: If water supply available, try a simple color-weight demonstration: dip the end of a paper towel into colored water and let the child mark how high the water climbs.
- Page 10: Have the child feel the cooling effect of dribbling water on the back of their hand while you read why sweat helps the body stay cool.
- Page 12: Hold an ice cube in a bowl of water and ask, “If the ice is solid, why does it float here, and how cold should lake freezes like?”
- Page 13: Keep the book’s question open: after asking what rain would do if water did not not stick together, invite a drawing before turning the page.
- Page 14: Choose one of the Did You Know? facts and test the paper-towel one with water and food coloring so the child can see adhesion-carried water climb.
