Scientific Process

Question 1

Procedure

Answer 1

a planned set of steps.

Scientists use a procedure to carry out an investigation or experiment.

Question 2

trial

Answer 2

a repeat of observations or tests

Performing multiple trials in an experiment or investigation will increase the reliability of results.

Question 3

variable

Answer 3

a factor that is changed in an experiment.

(In 5th grade we only have experiments with one variable.) The variable in our paper towel absorbancy experiment was the brand of paper towel.

Question 4

Data

Answer 4

Information collected during an experiment or investigation.

We write data in a chart while performing an experiment.

Question 5

hypothesis

Answer 5

a prediction based on evidence for a testable question.

Based on research and observations we each made a hypothesis about which paper towel would absorb the most water.

Question 6

Direct Evidence

Answer 6

Evidence that comes from measurements, tests or observations.

Data tables are full of direct evidence. We can compare data because it is clearly stated.

Question 7

Indirect evidence

Answer 7

Evidence that comes from inference.

Using the data that shows the amount of water remaining to calculate the amount of water absorbed is using indirect evidence.

Question 8

Investigation

Answer 8

the search for an answer to a testable question.

Question 9

conclusion

Answer 9

an explanation based on measurements and/or observations

We concluded that paper towel sample B was the most absorbent based on our data.
