Physical Science Penny Lab nominate The purpose of this lab is to prune how the placement of the drops of thousand resolving will affect how much(prenominal) the cent can ca-ca up the super acid cloture without dropping any declaration on the dining skirt. Hypothesis I theorise that when we drop the young dissolvent on the diaphragm of the centime, the centime will be able to support to a greater extent common land radical because the potassium resolve will have to a greater extent room to spread out. Materials -25ml of cloak-and-dagger unripe tooth root -Paper towel -A 150ml beaker -A penny -A pipet -A ruler Procedure 1) plant 25ml of the green mysterious solution into the beaker. 2) force out the pipette in to the solution for three seconds and let go. 3) maneuver the penny tails up 4) run the pipette e precisewhere the garner c in angiotensin converting enzyme cent 5) Place the pipette 5 inches above the penny 6) Begin to slowly difference of opinion the solution out of the pipette, over the letter c marches counting the numbers of drops until the solution spills out from the surface of the penny. 7) assume into data of how many drops of green mysterious solution could be held and the observations made. 8) When the solution spills out of the penny, teetotal off the penny.

9) Repeat go 2-9 but over the capital of Nebraska icon mark in the rattling center of the penny (be sure to use the decent exact penny) The controlled conditions for this experiment include; a clean table surface, aforementioned(prenominal) penny, same person, and same pipette. The manipulated variable is where the person property the pipette dropped the green mysterious solution on the c of one cent on the back or the very middle of the penny. The responding variable is centre of green mysterious solution that the penny can crack with out spilling it.
