Defining Characteristics of the Electric Charge Interaction
Hypothesis: Our group thinks that when a charged balloon comes into contact with paper the paper becomes attracted to the balloon causing it to stick to the balloon.We also believe that when the charge balloon comes close to the pile of foil the foil will be attracted to the balloon. And last we believe that when too charge balloons are close to eachother they will stick to each other.(Chris)
Summary:
In this investigation our group observed an electric charge interaction between a balloon and other objects such as aluminum foil, paper and another charged balloon. First we observed what would happen if a charged balloon came close to a pile of foil. When the charged balloon came close to the foil the foil was attracted to the balloon causing the foil to fly up and stick to the balloon. Next our group tested what would happen if a charged balloon came close to a pile of shredded paper. When the balloon came close to the pile of paper the paper was attracted to the balloon so it flew up and stuck to the balloon but it was not as strong as the foil's attraction. Lastly our group tested what would happen if two charged balloons came close to each other. When the two balloons came close to each other they repelled each other. From this investigation our group learned that when two charged balloons come close to one another they repel each other. We also learned that metals like aluminum are attracted to electric charges.(Chris) Nicely done, very complete and concise. [3 - Great work]
Circumstances under which the electrical charge interactions occur:
Electrical charge interactions occur when a substance rubs against another substance causing it's electrons to transfer to another objects electrons. And then what has to happen with that now charged object in order for there to be an electric charge interaction?
Charged Balloon/Paper: When the charged balloon and the half centimeter ripped pieces of paper were relatively close, the static charge from the balloon caused the pieces of paper to attach to the charged balloon. The attachment looked exactly like when two magnets connected because of their magnetic poles. In this case, the balloon's electric charge forced the paper to link to the balloon. The evidence that supported this reaction was that there was a change in motion.(Brooke)
Charged Balloon/Foil: When the charged balloon and the half centimeter ripped pieces of foil were relatively close, the static charge linked the foil pieces to the ballooon with a strong force. The balloons electric charge forced the foil to connect to the balloon. The evidence that supported this reaction was that there was a change in motion.(Brooke) [3 - Great Job]
Charged Balloon/Charged Balloon: When the charged balloon and the other charged balloon were relatively close, the static charge from one balloon repelled the other balloon in the opposite direction. The evidence that supported reaction was that there was a change in motion.(Justin)
Other ideas related to electric charges: One real life example of static electricity is on the playground. When someone goes down the slide, the friction between the plastic slide and your clothing create static electricity. Then when you touch someone they feel a shock!!!(Justin) What is static electricity and static charge? [3 - Great Job]
