Scientific Method
The scientific method starts out with this step.
What is stating a problem?
This causes surface currents.
What is wind?
Looking at the Earth, list the following in the order of the amount of surface they take up from most to least.
Land, Freshwater, Ocean
1. Oceans
2. Land
3. Freshwater
We live in this layer of the atmosphere.
What is the troposphere?
This is the mixture of gasses that surround the Earth.
What is atmosphere?
True or false? In order for an experiment to be considered a good one, two variables should be being tested.
False. A good experiment should only test ONE variable.
The current that moves up the East coast through the Atlantic Ocean is named this.
What is the Gulf Stream?
This is water that enters the soil and goes between spaces in rocks.
What is groundwater?
This layer is where you would find the ozone layer.
What is the Stratosphere?
The majority of Earth's atmosphere is made of this gas.
What is Nitrogen?
True or false? If a scientist records sounds she hears from a cat, she is recording inferences.
False. She is recording an observation because she is taking the information in with her senses.
The process by which sun transfers energy to the earth is called this.
What is radiation?
Water changing from a solid straight to a gas is called this.
What is sublimation?
A tree in the sunlight losing water is an example of what?
What is transpiration?
This happens on mountains, which causes a need for oxygen tanks.
What is reduced air pressure, which means not as many air particles, so less oxygen for us to breathe.
This is the type of variable that is changed by the scientist during an experiment.
This affects the air temperatures of coastal cities due to convection.
What is ocean currents?
This type of rock has large pores that water can pass through.
What is Permeable?
This ozone layer protects us from this.
What is ultraviolet radiation? (or UV rays)
As you increase your altitude, this happens to the air pressure.
What is it decreases?
Which of these could be used as the question to begin designing an experiement?
A. My cat is very happy.
B. Cats want to eat people.
C. Cats have 2 eyes and a tail.
What is C?
Although I think my cat is super happy and does in fact want to eat me, there is no way for me to tell since my cat cannot speak English. There is no real way to test those things. However, I can observe cats and determine that healthy cats do have 2 eyes and a tail.
Energy transfer through air or water is called this.
What is convection?
This process brings nutrients to the surface of water that help support life.
What is upwelling?
The weight of air molecules being pulled down by gravity causes this.
What is air pressure?
The thermosphere is the warmest layer of the atmosphere, yet it feels cold. This is the reason.
What is having fewer particles.
Particles are hot, but there are not enough of them to retain the heat.
