Questions: Which statement would lose points on an exam about the scientific process? Alternative hypotheses can be proposed and tested after initial experimentation. A scientific theory is mainly an educated "guess" Supernatural phenomena are not scientifically testable. In a control experiment, the variable is not altered.

The statement that would lose points on an exam about the scientific process is:

• A scientific theory is mainly an educated "guess".

Explanation for each option:

1. Alternative hypotheses can be proposed and tested after initial experimentation.
   This statement is correct. In the scientific process, it is common to propose and test alternative hypotheses after initial experiments to refine understanding and explore different possibilities.

2. A scientific theory is mainly an educated "guess".
   This statement is incorrect. A scientific theory is not merely an educated guess; it is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has stood up to repeated testing and scrutiny.

3. Supernatural phenomena are not scientifically testable.
   This statement is correct. The scientific process relies on empirical evidence and testability, and supernatural phenomena, by definition, fall outside the realm of scientific testing.

4. In a control experiment, the variable is not altered.
   This statement is correct. In a control experiment, the independent variable is kept constant to provide a baseline for comparison with the experimental group where the variable is altered.

In summary, the statement that would lose points is the one that inaccurately describes a scientific theory as an educated "guess".
