scientific Methods
The first step in the scientific method is this
what is observation
quantitative observation is this
what is An observation that involves measuring and recording numbers.
What might a scientist collect with a net?
Insects or aquatic organisms
Why do scientists organize data into tables?
To make sense of a lot of information and identify patterns.
What is a variable in an experiment?
A factor that can be changed or controlled
After conducting experiments scientists do this
what is form a hypothesis
Give an example of a technique used in sampling
Water sampling or netting.
Why do scientists collect specimens?
To study and analyze them in detail and understand the biodiversity in an area.
What kind of data can be shown in a graph?
Trends or patterns in the data.
In a controlled experiment, what is the purpose of keeping all variables the same except one?
To test the effect of the one variable being changed.
Repeating experiments is important for this reason
What is ensuring results are consistent
What can scientists learn from sampling water in a stream?
hey can learn about the chemistry of the stream, including factors like pH and pollutant levels
What does a specimen represent in scientific research?
A sample that provides information about the larger population or environment.
What does a graph help scientists detect?
Trends or patterns that might not be obvious from raw data.
In the farmer's experiment, what variable was being tested?
The amount of water the plants received.
This is a tool scientists use to collect quantitative data
what is A scale (for mass), a ruler (for length), or a thermometer (for temperature).
What is the purpose of making observations in science?
To gather information about the natural world.
What are some examples of specimens that scientists might collect?
Whole organisms, tissue samples, or plant samples.
What was shown in the table about the trout specimens?
The masses and lengths of the trout and the average values.
What is a control group in an experiment?
The group that does not receive the experimental treatment, used for comparison.
scientists share their findings with others this way
what is publishing scientific papers.
What kind of data do scientists collect when they measure the mass of an animal?
Quantitative data.
How can preserved specimens be useful in science?
They can be used for future study and as a reference for comparison in new research.
How can organizing data help in presenting scientific findings?
It makes the information clearer and easier to understand.
Why is it important to control variables in an experiment?
To ensure that the results are due to the variable being tested and not other factors.
