Question

does the type of object affect throwing distance?
identifying components of cer
use the following information to answer the question about claim, evidence, and reasoning.

experiment:
a major league baseball pitcher throws four different objects at the same speed and angle. the distance that each one travels is measured and recorded.

data table:
\

$$\begin{tabular}{|c|c|} \\hline \\textbf{object} & \\textbf{distance thrown (feet)} \\\\ \\hline baseball & 325 \\\\ \\hline rock & 290 \\\\ \\hline paper plane & 28 \\\\ \\hline feather & 0.4 \\\\ \\hline \\end{tabular}$$

which of the following would be a claim statement for a cer?

• the type of object affects the distance it can be thrown.
• the distance thrown affects the type of object.
• the type of object does not affect the distance it can be thrown.

Explanation:

Analyze the scientific question and experimental setup

The scientific question is: "Does the Type of Object Affect Throwing Distance?"
The independent variable is the type of object, and the dependent variable is the throwing distance.

Evaluate the experimental data

The data table shows that different objects (Baseball, Rock, Paper plane, Feather) thrown under identical conditions travel significantly different distances (325 ft, 290 ft, 28 ft, 0.4 ft).

Identify the correct claim statement

A claim must directly answer the scientific question based on the evidence. Since the distances vary greatly, the type of object does affect the throwing distance.

• "The type of object affects the distance it can be thrown" directly answers the question in the affirmative, matching the data.
• "The distance thrown affects the type of object" incorrectly reverses the cause-and-effect relationship.
• "The type of object does NOT affect the distance it can be thrown" contradicts the experimental data.

Answer:

• The type of object affects the distance it can be thrown. (Correct answer)
• The distance thrown affects the type of object.
• The type of object does NOT affect the distance it can be thrown.
