  1. Investigation 1: Water Observations Line of Learning (LOL) Water is a liquid earth material. A property is a characteristic of a material or an object, something that you can observe such as color, smell and taste. When water soaks into another material, it is absorbed. Water beads up on some materials.

  2. Investigation 1: Water Observations Line of Learning (LOL) Water is absorbed by some materials. Water beads up on some materials.

  3. Investigation 2: Surface Tension Line of Learning (LOL) Surface tension is the skinlike surface on water (and other liquids) that pulls it together into the smallest possible area (sphere). A dome is the shape a drop of water takes when it is on a flat surface. It is like a flattened hemisphere.

  4. Investigation 2: Surface Tension Line of Learning (LOL) Water forms a dome on a flat surface. Surface tension makes water form a sphere or a dome. Soap added to water reduces its surface tension. The dome flattens when soap is added to water.

  5. Investigation 3: Water on a Slope Line of Learning (LOL) A slope is a slanted surface. Flow describes the movement of a liquid over a surface. Water flows down a slope. Bigger domes of water move down a slope faster. Water flows faster down a steeper slope.

  6. Investigation 4: Building a Thermometer Line of Learning (LOL) When water is heated, it expands to take up more space. When water is cooled, it contracts to take up less space.

  7. Investigation 4: Building a Thermometer • Line of Learning (LOL) • What happens to the water in a thermometer when it is heated? • Water expands, making the liquid column longer. • What happens to the water in a thermometer when it is cooled? • Water contracts, making the liquid column shorter.

  8. Investigation 5: Sinking and Floating Water Line of Learning (LOL) Materials sink in water if they are denserthan the water. Materials float in water if they are less dense than water. Hot water is less dense than room-temperature water; it floats on room-temperature water. Cold water is denser than hot water; it sinks in room-temperature while hot water floats on room-temperature water.

  9. Investigation 6: Water as Ice Line of Learning (LOL) Water expands and turns solid when it freezes. Ice floats in liquid water; cold water from the melting ice sinks.

  10. Investigation 6: Water as Ice Line of Learning (LOL) Water expands and turns solid when it freezes. Ice floats in liquid water; cold water from the melting ice sinks.

  11. Investigation 8: Evaporation Locations Line of Learning (LOL) Seriate means to put objects in order by one property, like the amount of water left. A thermometer is a tool used to measure temperature. The cups placed in the warmest locations had the most evaporation. The cups placed in the coolest locations had the least evaporation.

  12. Investigation 9: Surface Area Line of Learning (LOL) Surface area is the area of a liquid exposed to or touching the air. The most water evaporated from the flat lid. The least water evaporated from the cylinder. The flat lid had the greatest surface area. The cylinder had the smallest surface area.

  13. Investigation 9: Surface Area Line of Learning (LOL) Surface area is the area of a liquid exposed to or touching the air. The most water evaporated from the flat lid. The least water evaporated from the cylinder. The flat lid had the greatest surface area. The cylinder had the smallest surface area.
