| water | a liquid earth material made from hydrogen and oxygen |
| property | characteristic of a material; something you can observe such as color, smell or taste |
| absorb | when water soaks into another material |
| bead | water makes a dome-shape on some materials; no movement of water into another material |
| surface tension | skin like surface on water that is created by the attractive forces between water molecules |
| dome | the shape created by a drop of water when it is on a flat surface |
| slope | a slanted surface |
| flow | describes the movement of liquid over a surface |
| buoyancy | the ability to float |
| sink | stay under the water when a material has more density |
| density | closeness or compactness of molecules (for example: a ball of clay is denser that a thin boat made from clay) |
| variable | something that can be changed during an experiment, such as the materials, equipment or procedure, to see if it changes the results |
| capacity | amount of space inside a container or shape |
| cargo | load of goods carried by a form of transportation such as a boat |
| displacement | when an object is put in the water, it pushes some water away |
| dissolve | to break into particles when mixed with water |
| soluble | a substance that dissolves in water |
| contract | takes up less space; when water is cooled |
| expand | to take up more space; when water is heated |
| states of matter | water can appear in the form of a liquid, solid, or gas |
