FORCES & MOTION
Newton's 1st Law is INERTIA.
How did Newton explain his 1st Law?
Inertia means that an object in motion will stay in motion in the same direction, or will stay at rest, unless another force acts upon it. For an object to change direction or stop moving, something has to overcome inertia.
What is a SCIENTIFIC THEORY?
A scientific theory is a proposed description, explanation, or model of something occurring in nature.
These theories have to be testable so that scientists can use the scientific method to see if they work.
What does the UNIVERSE consist of?
The Universe consists of all of the PLANETS, STARS, GALAXIES, and other MATTER.
What do you call a scientist that studies WEATHER and CLIMATE?
A scientist that studies Weather and Climate is called a METEOROLOGIST.
What type of Natural Disaster causes the Earth to shake violently and can make buildings crumble to the ground in mere seconds?
An Earthquake
Newton's 2nd Law is ACCELERATION.
How did Newton explain his 2nd Law?
Acceleration is a change in velocity. That means acceleration can mean a change in speed or direction. Acceleration can be thought of as an object’s change in velocity over time.
The SCIENTIFIC METHOD is how scientists learn more about the world around us.
What are the first steps in the SCIENTIFIC METHOD? (2)
The first steps in the Scientific Method include:
*Making Observations
*Asking Questions
Name the 4 INNER PLANETS in our Solar System (closest to the Sun).
The 4 Inner Planets in our Solar System are:
*Mercury
*Venus
*Earth
*Mars
What WEATHER INSTRUMENT do scientists use to measure how Hot or Cold it is outside at any given time?
Scientists use a THERMOMETER to measure how Hot or Cold it is outside at any given time.
What type of Natural Disaster causes the Earth to explode out of a mountain top and spew ash, rocks, and lava over the surrounding land?
A Volcano.
Newton's 3rd Law is ACTION & REACTION.
How did Newton explain his 3rd Law?
Energy does not change, and that means it is constant. When one object applies force to another, the energy becomes an equal and opposite reaction.
The SCIENTIFIC METHOD is how scientists learn more about the world around us.
What are the middle steps in the SCIENTIFIC METHOD? (3)
The middle steps in the Scientific Method include:
*Developing a HYPOTHESIS
*Designing EXPERIMENTS
*Collecting DATA
Name the 4 OUTER PLANETS in our Solar System (called GAS GIANTS).
The 4 OUTER PLANETS in our Solar System include:
*Jupiter
*Saturn
*Uranus
*Neptune
Name 3 types of CLOUDS that scientists observe when forecasting the weather.
The 3 types of clouds scientists observe are called:
*Cumulus (puffy)
*Stratus (blanket)
*Cirrus (high and cold)
What type of Natural Disaster includes a vortex of heavy winds that can sometimes touch down on the Earth, ripping trees out of the ground and throwing cars miles away from where they were parked?
A tornado.
What type of SIMPLE MACHINE helps older or disabled people move around common spaces (schools, hospitals, shopping centers, etc.) more easily?
The Incline Plane (ramp)
The SCIENTIFIC METHOD is how scientists learn more about the world around us.
What are the last steps in the SCIENTIFIC METHOD? (2)
The last steps in the Scientific Method include:
*Drawing CONCLUSIONS
*Sharing RESULTS
Give 2 reasons why Earth is DIFFERENT from all of the other known planets in our Solar System.
Earth is different from the other planets in our Solar System because:
*It is mostly covered in water
*There is breathable air
*It is covered with LIFE (plants, animals, & humans)
Earth's most magnificent and enormous landforms are found where?
*High in the Mountains
*On the Ocean Floor
*In the Amazon Rainforest
*Across parts of India and China
Earth's most magnificent and enormous landforms are found ON THE OCEAN FLOOR.
What type of Natural Disaster causes cities to fill up with water, ruining buildings and roads just from heavy rainfall?
A flood.
Which SIMPLE MACHINE revolutionized transportation and allowed people to move greater distances faster and with less effort?
What is the difference between an OBSERVATION and an INFERENCE?
OBSERVATIONS are using your 5 senses to gather information.
INFERENCES are using your prior knowledge or opinions to draw conclusions.
What is the ONLY other place in our Solar System (besides Earth) where humans have walked?
The only other place in our Solar System where humans have walked is on the MOON.
What is the main difference between WEATHER and CLIMATE?
WEATHER is the condition of the outside air at any time or place, and it is constantly changing.
CLIMATE gives the big picture of what the weather is like over a long period of time.
What type of Natural Disaster causes bolts of electricity to shoot down from the sky, sparking wildfires and causing power outages to entire cities during a storm?
Lightning
