Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. the condition of the mint varied in each student group. one group of students were asked to leave a whole mint in their mouth, not moving it around, and let it dissolve. another group swirled a mint, while the other groups used mints broken into smaller pieces. see the chart for all of the manipulated variable. after reviewing that data table, what kind of result would you predict for the swirled, whole mint?

Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. The condition of the mint varied in each student group. One group of students were asked to leave a whole mint in their mouth, not moving it around, and let it dissolve. Another group swirled a mint, while the other groups used mints broken into smaller pieces. See the chart for all of the manipulated variable. After reviewing that data table, what kind of result would you predict for the swirled, whole mint?

A)The time is likely between 10-30 seconds.  

B)The time is likely between 40-80 seconds.  

C)The time is likely between 90-160 seconds.  

D)    The time is likely between 100-200 seconds.

            ANSWER: B) The time is likely between 40-80 seconds.

  EXPLANATION:The time is likely between 40-80 seconds.

By swirling the mint, this is agitating and creating a higher frequency of collisions between the saliva particles and mint particles, increasing the rate of dissolution. Therefore, the time is likely to be less than the mint cut in half but probably more than the mint when it is in small pieces.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
