when something soaks into a material
|
|
|
bead
|
when something sits on top of nother material
|
|
|
Water fact - water is absorbed by some materials...
|
Water fact - water beads up on some materials
|
|
|
surface tension
|
the skinlike surface on water (and other liquids) that pulls it together into the smallest possible area (sphere)
|
|
|
dome
|
the shape a drop of water takes when it is on a flat surface
|
|
|
Water fact - water forms a dome on a flat surface
|
Water fact - surface tension makes water form a sphere or dome
|
|
|
Water fact - soap added to water reduces its surface tension
|
Name the water facts you already know
|
|
|
slope
|
is a slanted surface
|
|
|
flow
|
describes the movement of a liquid over a surface
|
|
|
water fact - water flows down a slope
|
water fact - bigger domes of water flow down a slope faster
|
|
|
water fact - water flows faster down a steeper slope
|
Repeat the 3 facts that deal with slope and flow
|
|
|
expand
|
to take up more space, to become larger
|
|
|
contract
|
to take up less space, to become smaller
|
|
|
water fact - water expands when heated
|
water fact- water contracts when cooled
|
|
|
sink
|
to go to the bottom of something
|
|

Water Observations
1. Water expands and turns solid when it freezes. |
Water Observation
2. Ice floats in liquid water;cold water from the melting water sinks. |
|
|
evaporate
|
when the liquid molecules go up into the air molecules causing the liquid to "dry up"
|
|
|
water vapor
|
what is produced when liquid water changes into a gas
|
|
|
Water fact - wet materials become dry when exposed to air. The drying process is evaporation.
|
Water facts - water changes into a gas called water vapor and goes into the air.
|
|
|
seriate
|
to put objects in order by one property, like amount of water left
|
|
|
thermometer
|
a tool used to measure temperature
|
|
|
Water fact - more evaporation happens where temperatures are higher.
|
Water fact - less evaporation happened where temperatures were cooler.
|
|
|
surface area
|
the area of a liquid exposed to or touching the air
|
