Lab Safety
If you don't understand a direction or part of a lab procedure, you should...
What is ask your teacher or LC?
What are identify and state the problem AND form a hypothesis
Things that can change or can be changed during an experiment
What is a variable
Smell, color, texture and size are all examples of this type of data
What is qualitative data?
True or false? You organize your data in a chart or graph before you design your experiment.
False! You can't organize data before you've done the experiment.
This is what you need to do with long hair when conducting a lab
What is pull it back?
a testable idea that is a suggested solution to a problem; an educated guess
What is hypothesis?
The number of variables that you can change in an experiment
What is one (1)?
Mass, time, height, measurements are examples of this type of data?
What is quantitative data?
Name the step of the scientific method you use your information to draw conclusions about your experiment.
What is Analyze Results?
This is what you should NEVER chew in the science classroom
What is gum?
Numbers, observations, or information you collect in an experiment
What is data?
These are the variables that we keep the same to make sure that the test is fair.
What is the controlled variable
Given the numbers: 12, 15, 13, 12, 10, 14. This is 12.
What is the Mode?
You conduced an experiment and your data was wrong, so you do this...
What is use scientific reasoning to explain why your hypothesis was incorrect.
Define permitted.
What is allowing someone to do something
Scientific investigation questions are ones that require a person to do what?
What is experiment or test?
Two sets of plants. One is watered, and one is not. What type of variable is the water?
Independent variable
A data table is organized in rows and columns. Tell the direction of both rows and columns.
What is rows are horizontal and columns are vertical?
This is an example of what step of the scientific method: "My hypothesis was incorrect because the germs stayed on my hands even after I washed them with hot water and soap."
What is the Conclusion?
Name three items of safety equipment typically found in a classroom.
You should have three: eye wash, fire extinguisher, shower, fire blanket, safety goggles, apron, lab gloves
These are the 5 steps of the scientific method
What are: Ask a question, develop a hypothesis, research/conduct an experiment, analyze data, and write a conclusion
This is a characteristic of a fair scientific experiment.
What is having only 1 independent or manipulated variable at a time?
Find the mean of the following numbers: 100, 80, 0, 100, 45, 100, 83, 100.
What is 76?
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
What is...Independent-soil temperatures, Dependent-plant growth.
