Worksheet time: 14mins
What is wind?
lots of moving air
when it's windy
air
lots of air
What is the atmosphere?
gasses
gasses you breathe
air
a layer of gasses that surrounds Earth or any planet
What is gravity?
a force field that pushes
an energy source
a pulling force that all matter has on other matter
the force that keeps us on Earth
What makes air move from one place to another?
ocean waves
melting ice
differences in air pressure
the wind blows
In what direction does air move?
from low to high pressure
from high to low pressure
from east to west
from north to south
What causes atmospheric pressure?
the moon's gravity causes it
the atmosphere causes atmospheric pressure
wind causes atmospheric pressure
Earth's gravity pulls air against the planet, and anything in the air gets squished
What is the difference between an atom and a molecule?
an atom is bigger than a cell and a molecule isn't
molecules and atoms are the same
atoms are a little bigger and made of molecules stuck together
molecules are made of more than one atom stuck together in different combinations
What are the three most common states, or forms of matter?
smoke, fire, water
Earth, wind, and fire
light, sound, and electricity
solid, liquid, gas
Which of the following is an example of convection?
two hands clapping together to make a sound
electricity moving in a wire
a pot of water on the stove is heated from the bottom and the water begins to flow
a tree falls in the forest and nobody is there to hear it
What object is the source of heat that causes nearly all wind on Planet Earth?
the mountains
the sun
the ocean
the moon
What are the three main ideas of 6th grade earth science so far this fall?
1) air is liquid, 2) wind is water, 3) water is always liquid
1) air and wind move because the sun heats some parts more than others, 2) that moving air and wind curves because of Coriolis Effect, 3) that air and wind moves and mixed other stuff on the planet.
1) air is energy, 2) air doesn't do much, 3) when air moves it's called water
1) air and wind are the same, 2) wind always moves the same way, 3) wind doesn't do much
What is convection?
movement of a fluid caused by uneven heating
the reason the Earth orbits the sun
a type of chemical
a type of vacuum
What is true about all the air in the Earth's atmosphere?
It moves around but doesn't connect to anything else.
It's always still and doesn't move.
It's always moving and mixing, and moving things around.
Air mixes things up but never moves.
What is a model?
a person who puts clothes on for commercials
a type of food
a representation or version of another thing or situation
like a toy or statue that you can use to play with or look at
Why do people make models in science?
to help them understand and make things simpler
just because
for fun
because they have to for class
What is air?
a mixture of gasses
a mixture of gasses (78% nitrogen, 21% oxygen)
a gas (100% oxygen)
the stuff you breathe
What area of science is studied in La Conner Middle School's 6th grade science class?
earth science
chemistry
life science
physical science
What is Earth?
where we live
everything there is
a planet moving around the sun
the moon
What do we call the layer of gasses surrounding Earth or any planet?
gasses
air
oceans
the atmosphere
What is a gas?
a state of matter that keeps its shape
a state of matter that flows but will not expand or contract
a state of matter that flows and will expand or contract to completely fill any space or container
a state in China
Which of the following is a gas?
a rock
milk in a jug
a baseball
air in a balloon
What force keeps humans and other objects stuck to Earth?
pressure
gravity
air pressure
atmospheric pressure
What object has gravity?
all objects made of matter
Earth
a black hole
energy
What is pressure?
a pushing force
a pulling force
a force
air
What is AIR pressure?
the pushing force of air
the atmosphere
gas
any pushing force
In what direction does air pressure push?
sideways
down
up
all directions
In what direction does a sea breeze blow?
towards the land in the day because air is warmer and less dense there
towards the sea in the day because air is warmer and less dense there
towards the land in the night because air is warmer and less dense there
towards the land in the day because air is warmer andmre dense there
In what direction does atmospheric pressure push on your body?
it only pushes down on your body because pressure is the weight of air on top of you
it pushes sideways on your body because of pressure differences
it pushes on your body from all directions
it pushes up on your body because the air bounces off the ground
Which situation best describes the interaction between the Earth, air, gravity, and humans?
Earth's atmosphere is like a cloud
Earth's atmosphere is like a shell around the Earth that could be cracked and fly away
Air pressure and gravity are the same. Gravity and air pressure both keep humans stuck to Earth's surface.
Earth's gravity pulls down on air particles and then they smash against everything on the surface in all directions, including humans
What are the smallest particles of matter air (or any chemical) called?
substances
cells
atoms
molecules
What is a solid?
a state that moves through matter, like energy
a state of matter that holds its shape, like ice
a state of matter that flows and mixes but cannot be compressed or expanded, like water
a state of matter that flows, mixes, and can be compressed or allowed to expand, like steam
What would happen if Earth had no gravity?
not much
solid objects would explode
all objects on its surface would float away
the sun would go out
What would happen if the Earth didn't have atmospheric pressure?
objects would drift away from the planet
there would be no sunlight
there would be no darkness
all liquid water on the planet would fizz apart into vapor
Which of the following is a gas?
air in a balloon
juice in a bottle
a rock
a metal fork
Why do people make models in science?
for fun
because they have to for class
to help them understand phenomena and make things more clear
just because
What is a system?
pure energy
solid matter
a big thing with smaller things inside, interacting
a whole bunch of wires and electronics
Why do plants need the atmosphere to cycle matter?
they need light to grow
they need water, soil fertilizer, and carbon dioxide that it brings
they won't grow without people
they need electricity to grow
What kind of energy does a moving atmosphere bring to plants?
light
heat
electricity
fertilizer
Which of the following is most dense?
