2. Scientific Question
.What portable generator would work most efficiently for charging a phone.

3. Background
I chose this to see if I could construct a successful magnet motor.To see if a r/c car motor had enough power to charge a phone.Whick motor was best for charging a phone.

4. Hypothesis
If I test a magnet motor and an r/c motor for charging a phone then the R/C motor will work best.

5. Variables Dependent-The amount of battery after charging a phone.
Independent-Battery after test.
Control-The motors.

6. Procedure →Build magnet motor →Get r/c motor
→connect generator to magnet motor and charge
→Connect r/c motor to generator and charge
→Record data

7. Data Type Of Battery Battery Percentage 100%
After
tTest
Type Of Battery
100% 0%

8. Data
Battery percentages at 0% because the motor were not powerful.The magnet motor was not successful at all because there were no known successful blueprints on a magnet motor.

9. Conclusion →Which motor works best for charging a phone?
→Attempt to charge a phone using magnet and r/c motors.
→Magnet motor was not successful at working.R/C motor was not powerful enough to generate power with the generator.
→No the data did not support the hypothesis because my hypothesis was that the r/c motor would work best but neither motor did.
→I learned that neither magnet motors or r/c motor work best for charging a phone because they don’t generate enough electricity.
→A problem was constructing a successful magnet motor.Getting the motor to charge the pnone and yet neither of those thing were successful.↓

10. Conclusion
→Improvements that could have been made are a stronger r/c motor,a successful magnet motor,possibly a bigger better generator.
