The main reason scientists do repeated trials in an experiment
To check for accuracy
Jake is performing an investigation using caterpillars. He places a box under a bright light and covers half of the box so that it is shaded.

Based on his investigation, which of the following is an observation, NOT and opinion?
(A) Caterpillars are afraid of light
(B) Caterpillars move away from the light
(B) Caterpillars moved away from the light
A tool used to measure volume or liquid
measuring cup; beaker; graduated cylinder
Why do scientists write down their experimental procedure?
In order for the exact experiment to be repeated and compared by others
