Evaporation and Condensation
Water evaporates from the lake. (That’s evaporation.)
Then all that evaporated water gathers up in a cloud. (That’s condensation.)
![Page 20: Science Class](https://reader036.vdocuments.us/reader036/viewer/2022062405/55631a90d8b42a811a8b4bf1/html5/thumbnails/20.jpg)
If you put a cup of
water next to a window on a sunny day, by the end of the day some water will evaporate.
Like this picture, water droplets collect and condensate when you have a cup of cold soda or a cup of water with ice

Evaporation and Condensation
Evaporation is when water is heated and escapes into the atmosphere as a gas.
Condensation is when the water vapor cools and changes back into water droplets.

against each other; like if you rub your hands against each other that can cause friction.

Mass and Weight
Mass - the amount of matter in a object.
Weight – the measure of the pull of gravity on an object.
![Page 84: Science Class](https://reader036.vdocuments.us/reader036/viewer/2022062405/55631a90d8b42a811a8b4bf1/html5/thumbnails/84.jpg)
Mass
An object will have the same mass on Earth as it will on the Moon.
![Page 85: Science Class](https://reader036.vdocuments.us/reader036/viewer/2022062405/55631a90d8b42a811a8b4bf1/html5/thumbnails/85.jpg)
MassMass is
measured in grams by comparing it to a known measurement.
A balance is used to measure mass.

Weight
Weight is the measurement of the pull of gravity on an object.
Weight is measured using a spring scale.
Objects having less mass, weigh less than objects that have a lot of mass, which weigh more.

Refraction
The bending of light.

surface.

How refraction worksThe light rays hit
the water, slowing down the motion of the light rays. The light bends as it hits the water and makes the straw appear differently

How reflection works
The light rays bounce off the mirror

DefinitionsRefraction-the bending of light.Reflection- the bouncing back of light ray
from a surface. If our eyes didn’t refract light the world
would be white.

SummarySolid, liquid and gas are all states of
matter. Solid takes up a definite shape and a definite volume. A liquid takes up a definite volume and takes the shape of the container. A gas takes up both the shape and the volume of the container.
