INTRODUCTION At what pH levels does the Periplaneta americinegar with pH of 2.9, milk of magnesia with pHh of 10.5 ,tomato juice with a ph of 4.1, clorox with a ph of 13 and milk with ph of 6.6.ana die in? In this experiment we will find out what pH levels are deadly for the Periplaneta Americana by exposing them to different pH levels. The Periplaneta Americana will be exposed to vinegar with pH of 2.9, milk of magnesia with pH of 10.5 ,tomato juice with a pH of 4.1, clorox with a pH of 13 and milk with pH of 6.6. HYPOTHESIS If the Periplaneta Americana are exposed to a pH level lower than 5 then all of the Periplaneta Americana will die. VARIABLES IV: the vinegar with pH of 2.9, milk of magnesia with pH of 10.5 ,tomato juice with a …show more content…

Experimental group: Periplaneta Americana exposed to vinegar, clorox, juice, milk and milk of magnesia. Control group: the Periplaneta Americana that were killed by the spray insect killer with a pH level of constants: the place where the substance will be put, the number of Periplaneta Americana in each trial. The size of each Periplaneta Americana needs to be the same. The amount of substance that is applied to the Periplaneta Americana . …show more content…

Pour 25 ml of vinegar in one of the 30 ml beakers. put 10 Periplaneta americana in a 10 oz plastic cup. Grab a pipette and add 20 drops onto the Periplaneta americana, you will put 2 drops on each periplaneta americana wait for 2 minutes, then record on a table how many Periplaneta Americana are dead in the plastic cup. put 10 new Periplaneta Americana in a new plastic cup. Pour 25 ml of clorox in one of the 30 ml beakers. Again grab a pipet and add 5 drops onto each of the Periplaneta americana . Wait for 2 minutes, then record on a table how many Periplaneta americana are dead in the plastic cup. Put again 10 new Periplaneta americana into a new plastic cup. Now pour 25 ml of milk in one of the 30 ml beakers. Once again grab a pipette and add 5 drops onto each of the Periplaneta americana . Wait for 2 minutes, then record on a table how many Periplaneta americana are dead in the plastic cup. Put again 10 new Periplaneta americana into a new plastic cup. Finally pour 25 ml of milk of magnesia in one of the 30 ml beakers. Grab a pipette and add 5 drops onto each of the Periplaneta
