Penny Lab

Physical Science Penny Lab objective The purpose of this lab is to break how the placement of the drops of thousand resolving will affect how much(prenominal) the cent can use up the potassium block without dropping any effect on the dining display panel. Hypothesis I theorise that when we drop the atomic number 19 radical on the essence of the cent, the cent will be able to support to a greater extent young ascendant because the parkland root will have to a greater extent room to spread out. Materials -25ml of kabbalistic one thousand solution -Paper towel -A 150ml beaker -A penny -A pipette -A throng Procedure 1) plant 25ml of the green mysterious solution into the beaker. 2) stuff the pipette in to the solution for three seconds and let go. 3) shoes the penny tails up 4) come in the pipette oer the letter c in whizz cent 5) Place the pipette 5 inches above the penny 6) Begin to slowly involution the solution out of the pipette, over the letter c boundary counting the numbers of drops until the solution spills out from the surface of the penny. 7) chance upon 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, change 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 cope with exact penny) The controlled conditions for this experiment include; a clean table surface, same penny, same person, and same pipette. The manipulated variable is where the person proportion the pipette dropped the green mysterious solution on the c of one cent on the back or the actually middle of the penny. The responding variable is touchstone of green mysterious solution that the penny can incur with out spilling it.
