The semester final for Mr. Garcia's science class required students to design and conduct an investigation that would answer the question "Is styrofoam a better insulator than plastic?"
Which experiment would be most effective in helping students obtain evidence to use in answering this question?
100 mL of 70 °C water placed in 200 mL plastic cup
O A. 100 mL of 10 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
50 mL of 70 °C water placed in 250 mL styrofoam cup
OB. 100 mL of 70 °C water placed in 250 mL plastic cup
