What must take place for conduction to occur?
Objects of varying temperatures must be in contact.

Imagine that you shine a flashlight onto a blue piece of paper.
What colors of light are absorbed by the paper?
All colors except blue.

Give one example of an electromagnetic wave.
radio, microwave, infrared, light, UV, x-ray, gamma ray

Differentiate between the 5 spheres of Earth.
Geo - ground and rock
Atmos - gases that surround the planet
Hydro - liquid water
Cryo - frozen water
Bio - living parts of Earth

How do the properties of elements compare to the properties of a compund they form?
The properties of the compound are different than the properties of the elements.
200
In what types of substances can convection occur?
fluids --> gases or liquids

Heather puts a straw into a glass of water. She notices that the straw appears to be broken when she looks through the glass and the water from the side. Which term best explains why the straw looks like it is broken?
What is refraction?
200
What is a medium? Explain and also give 1 example.
The matter that waves transfer energy through.
Examples may vary. (Teacher will approve.)

How do sinkholes form? Amd what kind of weathering is this?
Rock under the ground dissolves and the ground on top caves in.
Chemical weathering
300
How do atoms form mixtures?
Atoms of different types physically combine.

A warm rock is in contact with the cooler ground. How will the tempertures of each be affected?
The temperature of the rock will decrease while the temperature of the ground under the rock will increase.
300
Red light waves and yellow light waves travel through air and strike the surface of glass. Only the yellow light waves travel through the glass.
What color must the light be?
yellow

What do radio waves transfer between a cell phone and a cell phone tower?
energy

If John rode his bike to a friend's house, which is 500m down the street, and it took him 50s to get there, how hast was John going?
Remember that v = d/t.
500m / 50s = 10 m/s
(Student must include the correct number AND unit to get this answer correct.)
400
Explain the difference between a homogenous mixture and a heterogeneous mixture.
Homogeneous - appears the same throughout (also called a solution)
Heterogeneous - you can see the various parts of the mixture

Vivian placed an ice cube in a tray of warm water. describe the direction of energy movement, and the type of energy transfer that will take place.
Energy in the form of heat is transferred from the water to the ice cube by conduction.
400
What could slow light down?
Moving from a vacuum (like outer space) into any kind of medium
400
How do you measure the wavelength of a wave?
Transverse - crest to crest or trough to trough
Compressional - compression to compression or rarefaction to rarefaction
(Student only needs to give one of these answers.)
400
What are the 3 types of rock, and how are each formed?
Sedimentary - compaction and cementation of sediment
Metamorphic - heat and pressure within the Earth
Igneous - cooling and hardening of lava

Compare the molecules of a compound and a mixture, by drawing a model of each on the board.
Both should have more than 1 kind of atom, but they should be bonded in a compound and not bonded in a mixture.
(Teacher will check your answer.)
500
How is radiation different from conduction and convection?
Radiation transfer heat in the form of EM waves, and can do this across empty space (like outer Space).
Also, radiation emits these waves in all directions.
500
Draw 2 diagrams that illustarte the difference between reflection and refraction.
The reflection drawing should show something bouncing back. The reflection drawing should show bending, but not bouncing back.
(Your teacher will check your answer.)
500
Explain the relationship between the wavelength and frequency of a wave.
As wavelength decreases, frequency increases.
As wavelength increases, frequency decreases.

How do the circulatory and respiratory systems work together to maintain homeostasis in the human body?
They exchange oxygen and carbon dioxide to supply cells with what they need and to get rid of waste products.
