PROPERTIES OF MATTER
What is matter?
Matter is anything that has both mass and volume.
What is energy?
Energy is the fuel needed to do work.
Give an example of 3 different types of forces.
Friction, gravity, magnetism, weight, an applied push, an applied pull
What type of energy flows through a circuit?
Electrical
Differentiate between rotation and revolution.
Rotation - to spin around on an axis
Revolution - to go around something
Which property of matter can be tested with a magnet?
Magnetism
What is the law of conservation of energy?
Energy is neither created nor destroyed. It simply changes form.
Applying a force to an object will change the object's ____ and/or ____.
Speed; Direction
TRICKY TRIPLE: What are the 4 parts of a circuit and which part is NOT needed for a functional circuit?
The 4 parts of a circuit are: power source, load, conducting path, and switch. The switch is not needed for a functional circuit.
What causes us to experience night and day?
The Earth's rotation upon its axis causes us to experience night and day.
TRICKY TRIPLE: Differentiate between heterogeneous and homogeneous mixture.
Heterogeneous mixtures are made of components that are distinguishable. You can SEE the different components. Homogeneous mixtures are made of indistinguishable components. You can NOT see the different components.
What is an energy transformation (aka energy conversion)?
An energy transformation is when one form of energy is changed, transformed, converted, etc. into a different form of energy.
How would applying a force to move an object impact the object's kinetic energy?
The kinetic energy of the object would increase.
Provide two examples of a power source.
Ex: outlet, solar panel, generator, battery
What two factors cause us to experience seasons?
The Earth's tilt and its revolution around the sun cause us to experience seaons.
Describe the molecular movement of each state of matter.
Solids - molecules are packed tightly together and vibrate in place.
Liquids - molecules are loosely connected and have a degree of freedom in their movement.
Gas - molecules move freely and independently.
What type of energy do mammals need for fuel and how do we get it?
Chemical energy; we eat other organisms (or fake food products (>.<))
TRICKY TRIPLE: Does gravity cause or stop motion?
It depends on the situation but gravity can and does both.
Differentiate between open and closed circuits.
An open circuit has a "break" or a gap in it, thereby disrupting/stopping the flow of electricity. Conversely, a closed circuit has no breaks or gaps in it, so the flow of electricity is not interrupted and can flow freely.
Earth's tilt is ___.
Earth's rotation takes ___.
Earth's revolution around the sun takes ____.
Tilt:23.5 degrees
Rotation: 24 hours
Revolution: 1 year (365 days)
State 3 properties of matter and state what they are.
Answers may vary.
Mass - how much matter is in an object
Volume - the amount of space something takes up
Density - how compact something is
Solubility - how well a substance dissolves in a liquid
State of matter - the state a substance exists in
Conductor/Insulator - the ability to transfer/restrict the flow of electrons and/or heat
DAILY DOUBLE: What type of energy is made as a byproduct of electrical, kinetic, mechanical, and chemical energy?
Thermal
1) What two factors impact force strength?
2) Explain the impact of each factor on force strength.
HINT: If ____ increases, what happens to force strength?
Mass; Acceleration
Both mass and acceleration have a directly proportionate relationship with force strength. This means that if increase the mass or acceleration, force strength also increases and vice versa.
DAILY DOUBLE: Draw a picture of a complete circuit and identify the 4 major parts.
Ex: Battery (power source) + wires (conducting path) + flashlight (load) + button (switch)
Explain why we have sunrise and sunset even though the sun doesn't rise or set.
The Earth's rotation makes it so different parts of the Earth are turning towards the sun (i.e. sunrise -> daytime) while others are starting to turn away from the sun (sunset -> nighttime).
