 Making a battery A: yes, because to turn on a light it uses energy caused by an electrical charge and our light did turn on, B:describe what makes up a battery. B:a battery needs positive and negative energy to give things an electrical charge. C:what do you conclude from your observations of the zinc-copper strips you placed in the copper sulfate solution ? C:the zinc was the positive energy and the copper was the negative energy, and them put together into the acid made a battery. D:what happened to your lightbulb after you removed the assembly from the solution? How could you explain to someone what happened? D:the light slowly faded and then finally turned off. E: In these activities you probably noticed that the bulb was not very bright. What could you do to make the bulb glow more brightly? E:well, I think it depends if you have a lightbulb with larger watts and a larger zinc and copper strip. If it had that I think it would be brighter.
