The topic:Water is a polar molecule that is both adhesive&cohesive.Water is an essential to life because it helps dissolve substance needed for ife.Water also helps create a stable environment because of its ability to store heat.Pure water always has an equal number of hydrogen ions&hydroxide ions.

Hypothesis:If the penny has too much water on top of it,it will spill.

Materials:We use tap water,penny,2 cups,dropper,paper towels,soap(dish),Ajax

Procedure:The first thing we did is we got tap water and try putting several drops on the penny without spilling it and then we got soap and did the same thing.We checked to see whether the tap water or soap water can stay the longest without spilling.

Conclusion:?

Can you guys help me with the conclusion?PLEASE thats all I'm asking for.

In conclusion we found the water to bead up like a dome until the increase in mass/weight overcame the Penny's ability to hold the water. Then the water ran onto the table across the floor. There was a bare electrical wire which the water shorted out and it caught fire, burning the building down. After the Fire Department left, we decide never to try this stupid experiment again!
You may want to reword it some, this this best I could do from what you wrote.

first of all the topic doesnt make any sense. the experiment is not actually right for biology because you have to know the chemical make up of soap- hence the chemistry part of it. and then when you use the the penny in the experiment you are dealing with the laws of physics. if you do not have any knowledge in chemistry and physics then you will not get this experiment. i would start off by rewording the topic and use a different experiment such boiling water and explaing the evaporation process.... just a tip

in case you extremely seem up the pass connection with the scripture at John 18: 6 you will see it factors to John 7:40 six the place it states "The officers replied: “in no way has [yet another] guy spoken like this.” They knew he grew to become into the "Christ" it somewhat is Greek for Messiah. It says no longer something approximately Him being God. alongside comparable traces, we could examine Philippians 2:9, the place the apostle Paul describes what God did after Jesus died and grew to become into resurrected. The verse says: "God exalted him [Jesus] to a great place and kindly gave him the call it somewhat is above another call." If Jesus grew to become into God or equivalent to God previously he died and God later exalted him to an superior place, might that no longer positioned Jesus above God? yet how ought to every person grow to be greater advantageous to God? And if he grew to become into God previously he died, how can God die? there is not any "secret" right here. Jesus is the Son of God. additionally, God consistently pronounced Jesus as his son, and Jesus consistently pronounced God as his father, exhibiting that God grew to become into older and had greater authority. He additionally pronounced that he got here to do God's will and not his very own, exhibiting 2 wills; his father and his. 2 separate wills. in case you like to pass on believing that God has 3 heads, then you definately ought to have 3 too, because you have been created in his image!
