A form of energy emitted by the Sun as well as light-producing objects on Earth.
What is light?
100
These characteristics can be used to identify a substance.
What are density, boiling point, melting point, and solubility?
100
This type of light has a longer wavelength than visible light.
What is infrared light?
100
These are affected by the Sun's gravitational pull.
What is everything in our solar system?
100
Flows through ecosystems from the sun through producers to consumers to decomposers.
What is energy?
200
This can happen to light, depending upon the properties of the object and the type and angle of light when it hits the object.
What is be absorbed or reflected?
200
Things that can be measured without changing the chemical properties.
What are physical properties?
200
This type of light is detected most often by its heating effect.
What is infrared light?
200
A layer of air, made up of many layers and gases that surround the Earth's surface keeping humans safe from the sun's radiation.
What is the atmosphere?
200
This is transferred from one organism to another and between organisms and their environments.
What is matter?
300
Some materials scatter light, and others do this.
What is allow light rays to pass through, but refract the light by changing its speed?
300
Matter can undergo physical changes which affect only these.
What are physical properties?
300
Infrared imaging can be used for these.
What is space exploration and satellite imaging?
300
These characteristics make Earth suitable to sustain life.
What are liquid water, a breathable atmosphere, and suitable amounts of sunshine?
300
Substances that are cycled between the living and non-living environments.
What are water, nitrogen, carbon dioxide, and oxygen?
400
The structure of the human eye can detect many of these, that are reflected by objects.
What is colors in visible light?
400
Physical changes can also involve changes in this.
What is energy?
400
Has shorter wavelengths than visible light.
What is ultraviolet light?
400
Has allowed humans to learn much about the workings of the solar system, the composition of planets and moons, and the effects of many types of solar radiation on the Earth and its inhabitants.
What is space exploration?
400
The survival of individual organisms and entire species can be affected by this.
What are changes in environmental conditions?
500
Optical illusions investigate these conditions.
What is those that impair vision?
500
The amount of solute that can be dissolved in a specific volume of solvent under certain conditions.
What is solubility?
500
These wavelengths are responsible for causing sunburns.
What is ultraviolet light?
500
Was built to allow space to be studied continually.
What is the International Space Station?
500
A period of inactivity in a mature seed prior to germination.
