Matter
What is a property of a solid?
definite shape and volume
molecules are tightly packed together
What is the 6th planet from the Sun?
Saturn
What are the basic forms of energy we studied this year?
light, heat, sound, electrical, mechanical
What is a conductor in regard to energy? What is an example of a conductor?
Conductors allow energy to flow through them.
Example: metal
What are the properties of minerals that we have studied this year to identify minerals?
hardness, color, luster, cleavage, streak
How can we change the state of matter between a solid, liquid, and gas?
Change the temperature
Between which two planets can you find the asteroid belt?
Mars and Jupiter
True or False: Energy is always created or destroyed
False: energy is never created or destroyed. It is transformed or transferred into a different form of energy
What is an insulator in regard to energy? What are some examples of insulators?
An insulator does not allow energy like heat or electricity to pass through them.
Example: rubber, plastic, glass, wood, cloth
How are igneous rocks formed?
By cooling lava or magma
What is a property of gas?
No definite shapre or volume
What are some major differences between comets and asteroids?
Comets have an ice tail, orbit the Sun, made of ice, rock, and dust
Asteroids are made of rock, are found between Mars and Jupiter, orbit the sun
What property of light do we observe when we put a pencil in water and it appears that the pencil is bent?
What are some familiar forces that we observe every day?
Pushes, pulls, and gravity
This type of rock is formed by extreme heat and pressure
metamorphic
How could we separate different mixtures?
Separate them by shape, size, magnetism
What are the similarities and differences between the inner and outer planets?
The inner planets are rocky planets, have shorter orbits around the sun, are smaller planets
The outer planets are gaseous, have longer orbits around the Sun, they have shorter rotations, they are larger planets
What is mechanical energy?
Energy of motion
How are mass and force related?
The more mass of an object, the more force required to move the object
The less mass of an object, the less force required to move the object
How are rocks and minerals different?
Minerals are non-organic and are composed of only one element
Rocks are made of minerals and contain organic material
What are different ways we could dissolve sugar in water?
Heat up the water, stir the solution, or break the sugar into smaller pieces
What patterns do we see that give evidence the Earth orbits the Sun?
Rotation: Day/Night
Revolution: Changing seasons, different stars visible during different times of the year
What path does light energy travel in?
A straight path until it strikes an object or travels from one medium to another
What is an unbalanced force? What do we observe with unbalanced forces?
Forces applied to an object in opposite directions that are not equal. The direction of the greater force will create motion in that direction
A student is trying to identify a mineral. They perform a test by scratching it with a nail. What properties of mineral are they testing?
hardness
