Question

everyone in ms. blaylocks science class must perform an experiment for the science fair this year. to begin this process, ms. blaylock asks her students to brainstorm four different questions that they could study. one of ms. blaylocks students writes down the following questions: 1. how does the mass of a toy car affect its speed down a ramp? 2. how does the position of the sun, moons, planets and stars affect a persons personality traits and daily behavior patterns? 3. which type of pan - copper, aluminum, or glass - heats up the quickest? 4. which type of chemicals can remove the cell wall of a plant cell? which of the above questions cannot be answered through a scientific investigation? a. question 2 b. question 1 c. question 3 d. question 4

Explanation:

Scientific investigations require testable hypotheses. Question 1 can be tested by changing the mass of a toy - car and measuring its speed down a ramp. Question 3 can be tested by heating different types of pans and measuring the time to heat up. Question 4 can be tested by exposing plant cells to different chemicals and observing the cell - wall removal. However, the position of the Sun, moon, planets, and stars affecting a person's personality traits and daily behavior patterns (Question 2) is not testable in a scientific way as there is no clear, controlled way to measure and isolate these effects.

Answer:

A. question 2
