I am helping my cousin with his science project and its quot;what materials keep ice from melting for the longest time?quot;Im using 3 ice cubes, alluminum foil, plastic wrap, and paper towel.Im going to wrap an ice cube in each and leave them on the kitchen table for 45 minutes.I need to know what are the dependent variables and independent variablesHelp please!
Air movement and warmth will make it dry faster but it won't be fastI would try putting the hairdryer on a low setting and keep it movingDon't center it on one spot.
use a fan or a hairdryer!!!!!!!!!!!!!
The dependent variable is the time it takes to completely melt one ice-cube, ?since the TIME DEPENDS on what the ice is wrapped inSo the independent ?variable is the material used aluminum foil ??The problem is that you can't plot an (x, y) point without two numbersTime ?is a number but aluminum foil isn't??You can make a bar graph where each vertical bar is a different material ?and the height of each bar is the melting time
