Question

what is a scientific question that can be answered through experimentation? choose what is an observation that is measured, counted, or calculated? choose what is a series of steps to investigate a scientific problem? choose what is the factor in an experiment that is changed by the experimenter? *

Explanation:

1. A scientific question answerable through experimentation could be "Does the amount of sunlight affect plant growth?". It has test - able variables.
2. An observation that is measured, counted, or calculated is a data point. For example, the height of a plant in centimeters.
3. A series of steps to investigate a scientific problem is the scientific method, which includes steps like making a hypothesis, testing it, etc.
4. The factor in an experiment that is changed by the experimenter is the independent variable. For example, in a plant - growth experiment, the amount of water given to plants can be an independent variable.

Answer:

1. "Does the amount of sunlight affect plant growth?"
2. Data point
3. Scientific method
4. Independent variable
