Behavior of Light Energy
What happens when light strikes a mirror?
It bounces back at the opposite angle.
This determines if something sinks or floats in water. More ___________ sinks and less __________ floats
Density
What determines if it is summer or winter?
The tilt of the Earth on its axis
Jonathan pulls his chair out to sit down. Is that an example of a balanced or unbalanced force?
Rain, hail, sleet, and snow are all this
What is precipitation?
Light can do 3 things when it hits a surface. What are they?
Reflect, Refract, or absorb
This is the process that causes water vapor to turn back into a liquid when heat is removed.
Condensation
__________________happens day to day while _______________ is determined over time. (Climate or weather)
Weather happens day to day while climate is determined over time.
In an experiment measuring how far a car will go on a ramp, what needs to be changed (dependent) and what needs to be measured? (independent)
Variables are the height of the ramp and the distance it travels.
The height of the ramp (independent) and the distance of the car. (dependent)
Boiling water changing to water vapor is an example of what?
evaporation
Name a tool that uses refraction to help us see things better.
lens, glasses, binoculars, telescope,
This happens when the sun interacts with the oceans.
Evaporation
the earth revolves around this object
What is the Sun?
All the things in the experiment that you want to keep the same. What is not being changed. (Independent, dependent or control variables)
Control or constant variable
Water droplets form on a piece of glass above a boiling pot of water. What process causes this?
Condensation
What happens when light moves from air into water or from water into air.
When light moves from air to water it slows down and bends causing objects under water to look different.
When light moves from water to air it speeds up.
This slows down thermal energy and keeps things hot or cold.
Insulator
What is the difference between rotation and revolution?
The Earth rotates on its axis while it revolves around the Sun. Rotation is spinning (24 hours) and revolution is moving around (365 days).
What is a dependent variable?
The thing that you are measuring in an experiment.
Name all 7 of the steps in the water cycle.
Evaporation, condensation, precipitation, runoff, collection, percolation, and transpiration.
light hits a mirror at an angle of 30 degrees, what will be the angle of the reflection?
150 degrees
This lets energy flow through.
conductor
The center line around the Earth that is closer to the Sun than the poles.
Equator
What is an independent variable?
The thing that you are changing in an experiment.
Fog is an example of what?
Water Vapor
