What is science?

What are closed toed shoes like gym shoes?
"If [independent variable] then [dependent variable] because [your logical thought process or rationale]."
What is the proper format for a hypothesis?
Group A is given the special juice to drink while they work. Group B is not given the special juice.
Group A made 1,587 stacks. Group B made 2,113 stacks.
What is an appropriate claim to the question: Does special juice increase the productivity of workers?
The special juice decreased the productivity of the workers.
or

The claim tester that uses your observations and verifiable information to assess a claim
What is evidence?
The type of data in the observation: "The monarch butterfly is very bright and colorful."
What is qualitative data?
When goggles need to be worn
What is when dealing with heat, chemicals, and/or glass?
To cause a change in the dependent variable because it's the one thing you as the scientist have direct control over to change
What is the purpose of the independent variable?
The reasoning in the mini CER:
Air is matter. We found that the weight of the ball increases by .5lbs each time we pumped more air into it. This shows that air has weight, one of the characteristics of matter.
What is "This shows that air has weight, one of the characteristics of matter."?
The claim tester that uses your background knowledge to see if the statement makes sense
What is logic?
The type of data in the observation: "The African forest elephant weighs 9,000 pounds."
What is quantitative data?
When you finish working with chemicals, biological specimens, and other lab substances, always…
What is wash your hands with soap and water?
The thing you are measuring or collecting data on that may be affected by the thing you changed
What is the dependent variable?
If the data SUPPORTED the hypothesis (If I play light jazz music while I’m sleeping, I will sleep for more hours before I naturally wake up because jazz music is supposed to be soothing.) what claim could you make to answer the question: Can listening to music affect your sleep?
Listening to jazz music while you sleep increases your length of uninterrupted sleep.
The claim tester that uses your gut feeling
What is intuition?
A hypothesis in proper format to the question: Does rubbing alcohol remove bacteria from my phone?
If I clean my phone with rubbing alcohol, then there will be [less] bacteria because [its proteins will be denatured].
Max number of independent variables in an experiment
What is ONE independent variable?
To make sure the change is coming from the independent variable
What is a control group?
If the data REFUTED the hypothesis (If I play light jazz music while I’m sleeping, I will sleep for more hours before I naturally wake up because jazz music is supposed to be soothing.) what claim could you make to answer the question: Can listening to music affect your sleep?
Listening to jazz music while you sleep does not increase your length of uninterrupted sleep.
The claim tester that looks at where the information is coming from and assesses their credibility to speak on that subject matter
What is authority?
A factor that should be a controlled variable (constant) to the question: "Does temperature affect heart rate?"
What is the type of organism?
What you have to do before you measure a solid (like agar powder) on an electronic balance
What is "tare" or "zero" the balance so it reads 0.00 grams?
To keep everything (except the independent variable) the same throughout the experiment so we can have direct evidence for a cause-and-effect relationship between an independent variable and a dependent variable
What are controlled variables?
Quantitative or qualitative information that can support a claim
What is evidence?
The claim tester that is the least reliable
What is intuition?
