HYPOTHESIS

Sand will be the best insulator than cotton and air.

HYPOTHESIS EVIDENCE

Air (0.03 W/m.K)Cotton (0.06 W/m.K)Sand (0.33 W/m.K)https://www.teachengineering.org/activities/view/wsu_heat_activity>.

CONCLUSIONSBased on the results of this experiment I conclude that sand is the best insulator. The data and observations in this experiment have the following trends and patterns, the sand has lower temperature change (4.67C) than the air (14.5C) and cotton (8C) in all 3 trials and mean.
