A student notices that there are situations in which her avocados go bad very quickly. She decides to test the effect of temperature on how fast the avocado ripens. She purchases 3 mini avocados and 3 regular sized avocados. She places 2 mini avocados in the refrigerator and 2 regular sized avocados on the windowsill. She then placed the last mini avocado and regular sized avocado in a paper bag under the sink. Is this a controlled experiment? Why or why not?

The last mini avocado and regular sized avocado in a paper bag under the sink is this a controlled experiment.

Explanation:

The last mini avocado and regular sized avocado in a paper bag under the sink is this a controlled experiment because it contains both the mini avocado and regular sized avocado in a paper bag under the sink, which is believed to have high temperature.

So to indeed know whether temperature has effect on the avocado, the control experiment is the mini and regular sized avocado in the paper bag under the sink.

Hope it helps.
