Observation means:
Hypothesis means:
Tools can help you measure
Data can be organized in many different ways to include
What should you be sure to do to stay safe when performing science activities?
is a summary of what scientists have learned by analyzing their observations.
When the shots were they were very close together or precise but not in the bullseye.
The shots were when in the bullseye of the target but they were scattered and not precise or close together
When analyzing data, the is the value that occurs most often.
The is the difference between the largest and smallest values.
A scientist's opinion is a valid source of information to use in a scientific investigation
Scientists can help people answer questions, solve problems and form new ideas through the use of scientific processes.
Scientific investigation starts with a testable question.
If you collect, organize, and interpret your data properly, you will always be able to draw a logical conclusion.
A hypothesis is an "if then" statement of what you think will happen in the experiment.
When interpreting data, scientists use values such as the mean, median, mode, and range.
We can draw better conclusions from a greater amount of data.
If you replicate another scientist’s investigation and come up with very different results, it means you performed the experiment incorrectly.
One way for scientists to ensure their work is valid is to not share their results with others
The steps used in scientific methods must always be performed in the same order.
It is important data is collected consistently and recorded in a useful way.
The dependent variable is the variable you can control.
Control group is a standard against which change is measured.
They are helpful tools often used to study things that are very large, have many parts or are difficult to observe directly. They are still not the actual object being tested so different results may occur
Define observation
