Question

you create the hypothesis \if the temperature is warm, then the crickets will chirp more often\ based on your current observations and background knowledge

you place a cricket into each of the three different tanks. one tank is room temperature. the second tank is heated with a lamp. the third tank has a layer of ice on the lid.

you count the number of chirps in each tank for one minute as soon as you put the cricket in the tank, and then again after 5 minutes.

select the statement(s) that accurately describe the data that might be gathered during this experiment.

the cricket in the cold tank chirped 40 times in the beginning and 29 times after 5 minutes.

the cricket in the room temperature tank chirped 43 times in the beginning and 42 times after 5 minutes.

the cricket in the warm tank chirped 44 times in the beginning and 81 times after 5 minutes.

the cricket in the cold tank seemed happier in the beginning and sadder after 5 minutes.

the cricket in the warm tank ate 1 ounce of food in the beginning and 3 ounces after 5 minutes.

Explanation:

The experiment is about counting cricket chirps in different temperature tanks. We need to identify statements with chirp count data (quantitative, objective) and exclude subjective (like "happier/sadder") or unrelated (like food eaten) data.

1. "The cricket in the cold tank chirped 40 times...29 times" – Valid (chirp count, cold tank data).
2. "The cricket in the room temperature tank chirped 43 times...42 times" – Valid (chirp count, room temp data).
3. "The cricket in the warm tank chirped 44 times...81 times" – Valid (chirp count, warm tank data, shows increase with warmth, aligning with hypothesis).
4. "The cricket in the cold tank seemed happier..." – Subjective (not measurable data for the experiment).
5. "The cricket in the warm tank ate 1 ounce..." – Unrelated (experiment is about chirps, not food consumption).

Answer:

• The cricket in the cold tank chirped 40 times in the beginning and 29 times after 5 minutes.
• The cricket in the room temperature tank chirped 43 times in the beginning and 42 times after 5 minutes.
• The cricket in the warm tank chirped 44 times in the beginning and 81 times after 5 minutes.
