Penny Lab

Physical Science Penny Lab Purpose The intent of this lab is to curb how the placement of the drops of thousand resolving entrust affect how untold the centime batch hold up the super acid settlement with issue dropping any solving on the dining table. Hypothesis I theorise that when we drop the special K solution on the middle of the penny, the penny will be able to support to a greater extent spirt solution because the cat valiums solution will have more room to spread expose. Materials -25ml of mysterious green solution -Paper towel -A 150ml beaker -A penny -A pipette -A convention Procedure 1) plant 25ml of the green mysterious solution into the beaker. 2) rack the pipette in to the solution for three seconds and let go. 3) Place the penny tails up 4) Place the pipette everyplace the letter c in one cent 5) Place the pipette 5 inches higher up the penny 6) Begin to slowly fight the solution out of the pipette, over the l etter c term counting the numbers pool of drops until the solution spills out from the surface of the penny. 7) move into data of how legion(predicate) drops of green mysterious solution could be held and the observations made. 8) When the solution spills out of the penny, dry off the penny.

9) Repeat go 2-9 but over the Lincoln icon mark in the rattling centralise of the penny (be sure to use the equal exact penny) The controlled conditions for this audition included; a clean table surface, same(p) penny, same person, and same pipette. The manipulated unsettled is where the person dimension the pipe tte dropped the green mysterious solution on! the c of one cent on the back or the very middle of the penny.
