Scientific Method
What is scientific method?
The method used to conduct a certain experiment based on a question.
What are the three steps to write a hypothesis?
If, Then, Because.
What is a Independent Variable?
The variable that is being changed throughout the experiment to answer the question.
What is a observation?
the action or process of observing something or someone carefully or in order to gain information. -Oxford dictionary
What is the 4th part of scientific method?
A prediction.
What does "if" mean in if, then, because?
This is restating the question that will be answered after the tests.
What is a dependent variable?
The variable that is being effected due to the independent variable.
What step is observation during scientific method.
The first step.
What is the final step to Scientific Method?
what does "then" mean in if, then, because?
This is answering the question in a educated guess before the experiment.
What is a control variable?
This is the variable that is not being changed throughout the tests.
its foundation of the experiment which makes the question.
What are the six steps to scientific method?
Observation, Question, Hypothesis, Prediction, Test, and Modification.
What does "because" mean in if, then, because?
What is the control variable in this situation: Paul is testing how far a water rocket could go with different types of fins.
The launcher and Rocket.
Is this a observation: Paul sees his classmates filled their water rocket 75% full, as he filled his 50%. This causes him to ask the question, does the amount of water in a water rocket effect the distance traveled.
Does this experiment follow scientific method: Paul enjoys planting sunflowers. He wants to test if sunflowers would grow faster in the sun, or with a lamp. Paul googles he question and finds out the answer.
No, he did not follow the steps of scientific method.
is this a proper hypothesis and why: if there is salt in the soil, then plant growth will decrease because salt absorbs the water plants need for photosynthesis.
Yes, this is a proper hypothesis, because it stated the if, then, and because.
what is the independent variable in this situation: Paul is testing how far a water rocket could go with different types of fins.
The different types of fins.
Is this a observation: Paul sees that his fin is shaped different then the rest of his classmates. His rocket also went the furthest. He was shocked.
No, this is not a observation. A observation must lead to a question.
