C. HOW DOES YOUR ENVIRO BATTERY WORK?
Your enviro battery works by immersing a pair(or pairs) of connected zinc and copper plates into an aqueous medium such as a potato, mud, water, or a piece of fruit. the zinc plate is the negative electrode; the copper plate is the positive electrode. When the metals are immersed into the electrolyte a chemical reaction takes place. The acid in the electrolyte breaks down the atomic structure of the copper and zinc, causing individual electrons to be released. Zinc is a more reactive metal than copper in this chen process. It generates electrons faster than copper in this chemical process. The excess electrons flow from the zinc plate to the copper plate. This flow of the electrons from a reactive metal to a less reactive metal forms a small current which is strong enough to power a small light bulb, a small watch or a sound chip.

- Waist: Measure the narrowest part of your natural waist, holding the measuring tape loose enough to fit comfortably.
- Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
- Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
- Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
