Intro To Science - Section 2 Flashcards
What are the ways in which scientists answer questions and solve problems?
Scientific method
Any use of the senses to gather information is
Observation
What are observations that are made with tools?
Measurements
What compares energy output with energy input?
Efficiency
What is a possible explanation or answer to a question?
Hypothesis
What compares the results from a control group with the results from experimental groups?
Controlled experiment
When is the one factor that is changed during a controlled experiment?
Variable
What are any pieces of information acquired through experimentation?
Data
Scientific method
Ways in which scientists answer questions and solve problems
Observation
Any use of the senses to gather information
Measurements
Observations that are made with tools
Efficiency
Compares energy output with energy input
Hypothesis
Possible explanation or answer to a question. A good hypothesis is testable
Controlled experiment
Compares the results from the control group with the results from experimental groups. The groups are the same except for one factor called a variable
Variable
One factor that is different than everything else in a controlled experiment
Data
Any pieces of information acquired through experimentation
What is the first step of the scientific method?
Ask a question
As part of the scientific method, after you ask a question what is the next step?
Form a hypothesis
As part of the scientific method, after you form a hypothesis what is the next step?
Test the hypothesis
As part of the scientific method, after you test the hypothesis what is the next step?
Analyze the results
As part of the scientific method, after you analyze the results what is the next step?
Draw a conclusion
As part of the scientific method, after you draw a conclusion what is the last step?
Communicate your results
Name the steps in the scientific method
1) ask a question
2) form a hypothesis
3) test the hypothesis
4) analyze the results
5) draw a conclusion
6) communicate the results
What are some ways to communicate the results of an investigation?
Write a scientific paper, make a presentation, or create a website
Why graphs and charts useful for analyzing results?
Information is easier to see and understand when is organized into charts and graphs
Why is boat efficiency important?
It saves resources such as fuel
What is the purpose of asking questions?
Helps focus the purpose of an investigation
What is one way to test a hypothesis?
Do a controlled experiment
