Fruit battery inquiry
1. Investigating Fruit Batteries
Learning challenge: Can you design an
experiment to produce the biggest voltage in a
fruit battery.
Inquiry question: What factors affect the
voltage produced in a fruit battery?
2. What do you see?
What do you think?
What do you wonder?
3.
4. The Challenge:
Find the best combination of fruit and metal to get the biggest electrical potential.
You need:
1. A focused question or aim
2. List of equipment to use
3. A labelled circuit diagram
4. A 5 step method
This is my method:
Step 1: __________________________________________________
Step 2: __________________________________________________
Step 3: __________________________________________________
Step 4: __________________________________________________
Step 5: __________________________________________________
My question is:
_________________________________
_____________________
The equipment I need is:
1. __________
2. __________
3. __________
4. __________
5. __________
6. __________
7. __________
8. __________
This is my circuit:
7. P: Was the voltage the same or different when you changed the
combination of metals?
Extension: Was the voltage the same or different when you changed
the type of fruits?
Ev: How do you know this?
Ex: Why did the voltage change when the metals or the fruits
were changed?
