Hypothesis

We think the pickle will be the best generator since it is high in salts and acids

Research

General 

  • Energy 
  • Electricity is when a negative (-) charge travels to a positive (+) charge    
  • A electrical circuit ( that’s when electricity travels in a closed circle ) 

Specific 

  • The Conductivity (how good electricity goes through things ) of foods
  • Foods generating electricity  
  • Foods with acid and salt might generate electricity

Project

  • Our project might be a new way to generate electricity
  • A way to make electricity without harming the environment.
  • Lighting up a light bulb with a potato

Variables

Independent 

Varibleble

dependent

Variable

Controlled Variable

The food item is what will be changing each time.

-How bright the light bulb is 

-The current or voltage

-The light bulb stays the same

- wires

- space between each copper and zinc plate

Procedure

  1. Get your materials out.
  2. Choose your food item
  3. Put copper PLate  into the food item 
  4.  Attach 1 alligator-clip wire to  the end of the copper Plate
  5. Get the zinc plate and put it in to the food idem
  6. Get the other wire and attach it to the end of the zinc plate
  7. Add 1 more food by following the previous steps without attaching wires to the copper or zinc plates.
  8. Attach the wire on the copper plate to zinc plate on the second food idem
  9. Attach a wire to the copper plate on the second food idem
  10. Attach the wire on the copper plate on the short leg of the light bulb
  11. Attach the wire that's attached to zinc plate to the long leg light bulb
  12. Put both sides of the multimeter to each leg of the light bulb 
  13. Repeat with the other foods

Observations

Food items 

Did the bulb light up

Test one

Test two

Test three

Potato

yes
  • 1.603 
  •  1.592 
  • 1.6298

Pickle 

no
  • 0.1- 0.2 
  • 1.295 
  • 1.219-1.218 

lemon

no
  • 1.556 
  • 1.586
  • 0.1

Lime 

no
  • 1.547 
  • 1.573
  • 1.590 

Navel oranges

no
  • 1.614-1.615 
  • 1.582-1.581
  • 1.601 

Analysis

Conclusion

Our hypothesis was incorrect the pickle didn’t generate as much electricity that we thought it would, maybe because all of the other food items that we used had natural occurring acids and salt but in a pickle they are all added into it so the food items with natural occurring acids and salts will generate more electricity than food items with unnatural occurring salts and acids.All the food items generated mostly the same amount of electricity but only the potato lit the light bulb up. So in conclusion the potato generated the most electricity overall.

Application

this might be a renwable soucre of eletricaty with no evarmental inpackt,  which is good becuse lots of ways to make eletricity like burning ccoal hurt the envierment.

Sources Of Error

we use to big of a little bulb at frist but you changed it
