Jared investigated chemical reactions based on smell, color change, and release of bubbles. What type of evidence would support any conclusion Jared makes?
A An observation****
B An estimation
C A calculation
D A measurement
a
The correct answer is A, an observation.
When Jared investigates chemical reactions based on smell, color change, and release of bubbles, he is gathering evidence through his senses. These observations are direct evidence that can be perceived and recorded through human senses.
Estimations, calculations, and measurements are different types of quantitative evidence that involve numerical values and precise measurements. While these methods are important in scientific investigations, they may not be applicable in this specific scenario where Jared is relying on qualitative evidence. Therefore, A, an observation, would be the most appropriate type of evidence to support any conclusion Jared makes based on his investigation.
