Scientific Method
By:Brionna B.
There 7 steps to the Scientific Method.
- State Problem/ Question - the scientist first comes up with a question or problem that needs to be solved.
- Gather Information - the scientist does research to see if the problem has already been solve, if not they see what they can learn.
- Form a hypothesis - A hypothesis is educated guess that answer the problem or question.
- Perform an Experiment -This is when the scientist test their hypothesis, there can only be one different(the variable.)
- Analyze Data -After the experiment is over, the data that is collected is analyzed(review).
- Draw Conclusion - After analyzing the data, the scientist looks back their hypothesis, the scientist looks to see if the data does or doesn't support their hypothesis.
- Repeat Experiment Or -
If the hypothesis is supported then the scientist repeats the experiment, the scientist needs to make are always the same. - Revise Experiment- If the hypothesis is not supported, the scientist changes their hypothesis, the scientist then starts the whole process again.
Question:Are Electric Cars Slower Than Regular Vehicles ?
- Jamie & Adam didn't do any reseach.
- Hypothesis: If you make a electric vehicle, then it will be a lot slower than gasoline vehicle.
- Manipulated variable: what is being tested,-an electric vehicle.
- Responding variable: what is being observed and measured,- how the electric vehicle compared to the regular vehicle
- Controlled Variable: what is kept the same,- a regular vehicle that is the same or similar.
- Data collected: Jamie and Adam mostly collected and compare how fast diffrent electric vehicles are than regular vehicles.
- What did they learn : that Electric Vehicles are fast than regular vehicles.
- THE MYTH WAS BUSTED.
Question: Do greenhouses gasses really make our planet warmer ?
Did They do any research : Yes
What was their hypothesis : If you increased the amount of carbon dioxide and methane, then the temperature will be greater.
Manipulated Variable: what is being tested , -increasing the amount of carbon dioxide and measured .
Responding Variable: What is being observed and measured , - the temperture inside of the first two greenhouses.
Controlled Variable: what is kept the same ,- greenhouse size, amount of light starting temperture.
Data Collected : They made four greenhouses, first greenhouse had a lot of carbon dioxide, secong house had a lot of methane, and third and fourth had regular air in them.
What did Jamie & Adam find out : Greenhouse gasses make planet the warmer.
Myth Busted
Cow Calamity
Is all of the methane gas produced by cows really bad for the environment?
Hypothesis: If you produce alot of methane, then cows are bad for the environment.
Manipulated Variable : what is being tested , - using methane instead of gasoline in a lawn mower.
Responding Variable : what is being observed and measured , - using a greenhouse gas as a power source rather than let it become pollution.
Controlled Variable :what is keep the same , - using the same lawn mower.
Data collected : They did collected a lot of data , they found out that methane produced by all cow has a big affect on the planet.
Did they do research : Yes.
What did Jamie and Adam find out : They find out that cow's poop has a big effect on the environment.
That myth was busted!
What I learned !
I learned a lot from this video here some examples:
1. Some electric cars are faster than race cars, and they are better for the environment.
2. Methane gases are good for using in a lawn mower.
3.And Greenhouses make the planet warmer.
This video was very helpful in many ways!
