do you ever wonder how batteries create enough power to light a flashlight? you can use chemistry to find out!
chemistry is a kind of science that studies what everything is made of and how it works. in this experiment, you’ll use coins, vinegar, and salt to create a battery. this battery will be able to make electricity, a kind of energy that is carried through wires and is used to make machines and light bulbs work. if you follow the steps correctly, the battery should light a tiny light bulb.

what you need
to start, gather your supplies:

• a cardboard cereal box
• 7 nickels
• 7 pennies
• white vinegar
• salt
• plastic mixing bowls
• a glass measuring cup
• a 1 - teaspoon measuring spoon
• an led light bulb with long wires
• aluminum foil

fill in the blank to describe the experiment.
by following the steps in this experiment, you will build a dropdown with options: penny, nickel, flashlight, battery to turn on a light bulb.

Explanation:

The text describes an experiment where the goal is to build something to turn on a light bulb, and the experiment is about creating a battery (using coins, vinegar, salt etc.) to generate electricity for the light bulb. Among the options, "battery" is what is built in the experiment to power the light bulb, while "penny" and "nickel" are materials used, and "flashlight" is not what's built here (the experiment is about making a battery to light a bulb, not a flashlight).

Answer:

battery
