Analyze the question and options

The question asks: "Which of the following would be an EVIDENCE statement for a CER?"
The options describe relationships between the length of the pendulum and either the number of swings or mass.

Evaluate the options based on scientific principles

• Option 1: "The data shows that as the length of the pendulum increases, the number of swings decreases."
• Option 2: "The data shows that as the length of the pendulum increases, the mass increases."
• Option 3: "The data shows that as the length of the pendulum increases, the number of swings remains the same."

Determine the correct physical relationship

A longer pendulum has a longer period, meaning it takes more time for one swing. Therefore, in a fixed time interval (30 seconds), a longer pendulum will complete fewer swings (the number of swings decreases). Option 1 correctly states this empirical evidence.

Answer:

• (A) The data shows that as the length of the pendulum increases, the number of swings decreases. (Correct answer)
• (B) The data shows that as the length of the pendulum increases, the mass increases.
• (C) The data shows that as the length of the pendulum increases, the number of swings remains the same.
