Potato Powered Clock as Science Fair Project - #GlueNGlitter #CBias

The Science Fair has been something I have looked forward to every year!  Call me crazy.  I love science and always have!  Picking the subject, creating the display and actually making it work can be a headache, but the moment your kids eyes light up and they are busting with excitement makes it all worth it!

This year my oldest came home knowing exactly what he wanted to do, he had seen it in years past and was determined to do it this year - to make a battery out of a potato.  Before I was agreeing to anything I checked, and Wikipedia to first see how complicated this would actually be.  All of the websites said it was easy and showed detailed instructions (later I would find out there were key details not mentioned! But don't worry!  I'll tell you what they omitted!).  My son was excited to also try a mandarin orange, a banana and anything else we had laying around.

First off we headed down to our local Walmart (you can follow along with all of the pictures on the Google+ story here) to get an Elmer's Tri-Fold display board, Elmer's glue sticks, Elmer's glitter paint, zinc coated nails, copper, alligator clamps and a SUPER low voltage clock (this is by far the trickiest part of the ENTIRE experiment - you have to have one 1-2 volt clock to get it to work.  We initially got one that took too many volts and ended up having to buy a eco-battery kit because it came with a super low volt clock that we couldn't locate anywhere else).

We got to work on setting it all up by inserting one zinc coated nail in each potato and one copper piece in each potato.  Connect one copper piece from potato 1 to one zinc coated nail in potato 2 (using conductive wire and alligator clips).  Then connect the unused copper wire (or red wire) to the positive clip where the battery would go in the clock.  Connect the unused black wire (connected to the zinc nail) to the negative clip in the battery compartment.   It should look like the below picture. 

The kit we had purchased also came with a low voltage light and a sound chip that can be powered by the potato or fruit.  My boys had tons of fun playing around with the different combinations to see what else would work.  Little did we know you could mix and match the fruit and it would still power the clock and sound chip.

For decorating the tri-fold board, we cut up strips of construction paper and used the glue stick to attach along the border, then decorated with the gold Elmer's glitter pens to make lightening bolts.  I used the silver Elmer's glue pens to highlight each section (purpose, hypothesis, etc.).  Blue Elmer's glitter pens for the title (blue is my son's favorite color).

My kids had a ton of fun playing around with the different ways to make it work and learned at the same time.  Can't get better than that.

Happy Science Fair Project Season!  What are you testing out this year?

How incredibly cool! Sounds like a great educational experiment!

This is awesome! We're looking for something to do for the science fair. Ironically, my son is working on circuits in science. We may give this a go. Thanks for sharing.

where do we find the kit? i didn't see a link!
thank you!

But the type of saturated fat, fat in these foods, the main originator of cancer, diabetes, and heart, which is directly linked to clogged arteries. When you consume these fats, they make platelets in your blood stream.

This makes platelets sticky bit later form clumps that are connected resep dimsum to the walls of the arteries that supply vital areas of your body with oxygen and nutrients. This small clumps make a wall plaque that will eventually lead to heart attack or stroke.

Unlike the good fats, such as vegetable oils (including olive oil and sunflower), which actually has a protective effect on health.
The damage done by saturated fats can be found in margarine, vegetable oils and partially hydrogenated everything.

Saturated fats have also been shown to increase levels of bad cholesterol or low density lipoprotein. These fats also can resep sop buah stay in the body longer and improves blood circulation triglyceride lowering good cholesterol or high-density lipoprotein

Bad Carbohydrates

Starch in potatoes is composed of simple carbohydrates. Most fries made of white darikentang proved much easier to convert in the body in the form gula.Ketika your body needs carbohydrates in quick time, this sugar forced "absorb" in order to be used as energy.

Otherwise, the sugar will be stored as cara membuat bubur ayam fat. Unless you consume before or after strenuous exercise, the sugar may be directly decomposed. But if you consume them in large quantities without great activity, will quickly convert carbohydrates into sugar high and causes increased insulin production in the body. If the supply insulan continue to soar, insulin resistance is also growing and the body of a higher risk of heart disease and diabetes.

Trans fat

Trans fats are fats derived from vegetable oils pemanasam. Just like saturated fat, trans fatty acids on the fries are also cara membuat klepon at high risk of causing heart disease, cancer, and diabetes.

Trans fats act as carcinogens in the body. The fries were memilikitingkat high acrylamide, also claimed to be cancer-causing substances. Although there has been no conclusive results regarding the relationship between the children who frequently consumed French fries and cancer, but health experts recommend that they avoid these foods.

Given that, every year of cancer in children continues to rise in the age of 3-5 years.
