SC10 Biology-unit project: Heterochromia by Kedrick and Jacob (office.com)
Reflection: I learned that being partners with others don’t always work out and that I should just do group work by myself, I also learned that it is important to be for people to know what mutation I studied on so that people who see other people with heterochromia will know what the mutation is.
A) Purpose: Which fruit will produce the most electric voltage?
B) Hypothesis: When I use apple as a power source it will make the least amount of power.
C) Materials: 1 voltmeter, 2 wires, 1 nail, 1 copper strip, at least 3 fruit/vegetables.
D) procedure: Step 1: Cut the piece of fruit Step 2: put in 2 pieces of metal Step 3) Attach the voltmeter using wires Step 4) Record the results Step 5) Compare results from several pieces of fruit.
E) Reasoning (why): the apple will produce the smallest voltage because the apple is the easiest fruit for me to cut so that means it is the weakest fruit meaning it will produce the weakest voltage.
Results: apple charge is 0.15 v
potato charge is 0.3 v
What is Causing electrons to flow
Answer: The fruit is an electrolyte solution allowing the electrons on the metal to flow.
What are the independent, dependent, and controlled variables in this experiment.
Answer:
How can we modify our experiment to improve our results.
Answer: Maybe if I had more fruits.
What could be sources of error in our experiment.
Answer: The machine now working, having no wires, using fruit that doesn’t work.
How can you use this in your everyday life
Answer: Maybe if i’m showing some else this experiment
