Air is matter.

We found that the weight of the ball increases by .5lbs each time we pumped more air into it.

This shows that air has weight, one of the characteristics of matter.

The researchers placed plants in pots of different sizes and let them grow for one month.

Some plants grow taller than others when grown in large pots.

According to the data, a plant grown in a 5 cm pot only grew to be 4 cm tall, where as a plant in a 10cm pot grow to be 8 cm tall.

The researchers observed 10 plants total, 5 planted in smaller pots and 5 planted in larger pots.

When plants are placed in a bigger pot, the roots have more room to spread out, making it more optimal for a plant to grow taller.

Sometimes, plants just enjoy being in a bigger pot. When a plant enjoys its pot more it will grow taller

No one really knows why, it just happened.

The evidence supports the claim that plants grow taller in a bigger pot because a plant grown in a 5 cm pot only grew to be 4 cm tall, where as a plant in a 10cm pot grow to be 8 cm tall.

According to the study, students who went to sleep later, causing them to get less sleep, scored an average of 30% lower on their exams.

The claim of an article I read in another class was that students who sleep less do poorly on tests.

Students reported feeling more sluggish over all, making it hard to focus and do well on their exams.

According the the study, the kids were sleepy. When I am sleepy, I also do poorly on my assignments.

When a person has had less sleep they can have a harder time remembering things, focusing, and reading. All of these can result in mistakes on an exam which could explain the lower score.

When a person has had less sleep they are often in a bad mood. Exams also put people in a bad mood.

I got an A on my last history test after studying all night, so maybe they did the experiment with people who are bad at studying?

The evidence supports the claim that people who get less sleep do poorly on exams because students who went to sleep later, causing them to get less sleep, scored an average of 30% lower.

Yes, there is a best color but I'm not telling.

There is no single "correct" color to use for a science notebook.

There is only one correct color to use as a notebook for any subject.

I have always used purple notebooks for science class.

No, students who sleep do not study.

Students who are well rested are likely to be able to focus, remember information, and participate in class.

I will test this by sleeping in class.

Yes, I think so.

Blake runs so fast that the paper appears to move backwards but actually stays still

When Blake moves forward, the air moved into the space he had been and pushes the paper around.

When Blake pushes backwards on the paper the paper pushes forward on him. The paper moves backward and Blake moves forward.

Newton was wrong.

You don't move upwards, you stay where you are and push the earth down. The earth isn't standing on anything so it easily moves.

The question is wrong because you can't push the earth downwards. To jump you pull yourself upwards.

Don't overthink it. it just works.

When you push down on the earth it pushes back up on you. The upward force of the earth in reaction to your downward push makes you move up.

The player pushing on the ball is the applied force. The ball pushing on the player is the reaction force.

The ball pushing on the player is the applied force. The player pushing back on the ball is the reaction force.

The player's hand moving is the applied force. The ball moving is the reaction force.

The player pushing on the ball is the applied force. The wind pushing on the ball is the reaction force.

The ground pulled the ball down (applied force) but the air pushes it back up (reaction force)

Gravity pulled the ball down (applied force) and when it hits the ground the ground pushes it back up (reaction force)

The air pushes the ball upward (applied force) while the person pushes it down (reaction force).

Darth Vader pulls it down (applied force) but Obi-wan pushes it up (reaction force).

The object's speed does not change, so there is no force

The direction the object moves is changing, there must be an outside force.

The center of the object doesn't move, so there is no outside force.

The object is above the ground, there is a downward force.

A falling body accelerates at a constant speed.

The motion of an object is constantly changing due to magnetic forces.

The force of friction causes an object in motion to move faster.

A body in motion will remain in motion unless influenced by an outside force.

The object is not in motion, so there the forces are balanced.

It is heavy, so the downward force must be stronger.

It is heavy but he is strong, so the upward force must be stronger

It you push and pull at the same time it will move to the side.

If the mass increases the object will accelerate more.

If the mass increases the object's acceleration will not change.

The acceleration should decrease when the mass increases

If the mass increases, the force increases as well.

If the net force increases the object will accelerate more.

If the net force increases the object's acceleration will not change.

The acceleration should decrease when the net force increases

If the mass increases, the net force increases as well.

The net force acting on the object increases.

The net force acting on the object decreases.

The mass of the object increases (mass is added to the object).

The mass of the object decreases (mass is removed from the object).

$$F_{net}=m\cdot a$$

$$F_{net}=F_1+F_2+...$$

$$a=\frac{\Delta v}{t}$$

$$a=\frac{F_{net}}{m}$$

The acceleration stays the same because the mass stayed the same

The acceleration is multiplied by 9

The acceleration increases by $$3\frac{m}{s^2}$$ because of addition

The acceleration is divided by 3

The acceleration stays the same because the net force the same

The acceleration is multiplied by 3

The acceleration decreases by $$3\frac{m}{s^2}$$ because of subtratction

The acceleration is divided by 3

The acceleration stays the same because the increased net force is balanced by the increased mass.

The acceleration is multiplied by 2 because the Net force is multiplied by 2.

Newton's second law cannot be used to predict this outcome.

The acceleration is divided by 2 because the mass is divided by 2

There is no point on the graph where the net force is balanced.

A ball with a mass of 10 kilograms will have an acceleration of $$3.3\ \frac{m}{S^2}$$ because that is the largest acceleration recorded.

A ball with a mass of 10 kilograms will have an acceleration of $$5.0\ \frac{m}{S^2}$$ because that is the double the acceleration of the 20kg ball and this ball has half of that mass.

A ball with a mass of 10 kilograms will have an acceleration of $$1.25\ \frac{m}{S^2}$$ because that is the half the acceleration of an object with 20kg of mass and 10 is half of 20.

The student did not record a ball with 10kg of mass so it is impossible to predict if one will roll or have an acceleration at all.

Mantle

The Mantle never moves, it is a single solid layer

The core lights some of the mantle on fire and it explodes upwards making volcanos.

The core heats the mantle lower down, which rises up and pushes colder mantle out of its way, the cold mantle then falls down into the space left by the rising mantle

The core cools the mantle lower down, which rises up and pushes hotter mantle out of its way, the hot mantle then falls down into the space left by the rising mantle

Friction between the Mantle and the Crust causes a force to pull the crust in the direction of the moving mantle, causing plates to move apart.

Friction between the Mantle and Crust cause a force to shake the plate causing earthquakes

Friction between the mantle and plate sucks the plate down under the mantle causing magma to erupt

The rising mantle pushes up making mountains.

A fun world for a new Star Wars movie to happen on

Africa and South America used to be joined together, but split apart long ago.

Africa and South America are drifting towards each other and will soon fit together perfectly.

Ocean currents on either side of the Atlantic have eroded the coastlines into the same shape.

Africa and South America are currently the same place but were once two different places

Lystrosaurus swam across the oceans from one continent to another.

Lystrosaurus drifted on rafts of vegetation from one continent to another.

Africa, Antarctica, and India used to be joined together into a single landmass.

The fossils are actually of three different reptiles that look very similar.

Africa has always been near the equator

Africa was once in an area of the Earth that had a very cold climate

The equator of earth used to get cold while the poles would get hot. The climate moved but the earth did not.

Many small earthquakes happened which just look like glacial scratches

Seismic waves always slow down over time

Seismic Waves always speed up over time

Seismic waves travel slower through hotter materials and faster through colder materials

Seismic waves travel slower through colder materials and faster through hotter materials

The waves do not always travel the same speed through the mantel which means that parts of the mantel have different temperatures

The waves do not always travel the same speed through the mantel because there are multiple types of waves in the mantel

The waves do not travel the same speed through the mantel because the moon is moving

The waves do travel the same speed through the mantel but there are additional layers we haven't discovered

We think there are layers because of errors in our data that we haven't been about to fix.

Layers have different colors which affect the speed the waves travels.

Layers have different average temperatures and composition which affects the speed the wave travels

Layers have different depths and waves change speed as they travel further

Cold spots in the Mantle lead to sinking areas which pull crust down causing valleys which then need to be filled.

Hot spots cause part of the mantle to rise and push apart old crust, creating new crust where the magma cools

Cold spots cause part of the mantle to rise and push crust pieces together, leaving holes in which magma can cool and become new crust

Hot spots in the mantle lead to slow moving areas which get covered up by cold spots, causing mountains.

Since the continental crust is more dense, it subducts. This crust is very dry which makes the area at this boundary a desert

Since the oceanic crust is more dense, it gets subducts. This brings sea-water which causes the mantle to get colder and more solid

Since the continental crust is more dense, it subducts. This crust is very dry and gets hot as it moves so it melts into magma

Since the oceanic crust is more dense, it subducts. This brings sea-water which causes a reaction and makes magma
