Lemon Electricity Experiment

I recently investigated on how lemons and other fruits and vegetables can create electricity. I predicted that a lemon or lemons could do this. After all these weeks, I have found that with so many lemons you may be able to light a light bulb or run a motor. I have learned about how the lemon’s acid creates electricity if you roll it with pressure. I’ve also learned about how electricity runs through a circuit. The copper and zinc act as the two different metals or electrodes in a battery and the citric acid in the lemon acts as the acidic solution or electrolyte in the battery. Another thing that I learned is that lemons can produce a dim glow from an LED. I have lastly found that one lemon can produce a voltage of .906 volts but you can wire two or more to it. I’ve learned that electric current is a flow of atomic particles called electrons. Some materials, called conductors, allow electrons to flow through them. Electrons will flow from the “-“ electrode of a battery, through a conductor, towards the “+” electrode of a battery.


Here are more studies from this experiment with lemons to see if they can generate some electricity:

Materials

1. 1+ lemons
2. 1+ pieces of copper wire
3. 1+ pieces of zinc
4. Insulated wires
5. Wire clippers (alligator)
6. Sandpaper
7. 1 LED/flashlight bulb
8. Multimeter

Steps

1. Use the sandpaper to smooth any rough spots on the copper and zinc.
2. Squeeze the lemon gently by rolling it but try not to rupture the skin.
3. Push the copper wire and zinc into the lemon as close together as possible but not touching.
4. Wrap the insulated wires around the copper wire and zinc.
5. connect the wires to the LED in order to see it light up!


Question/problem

Can lemon create/produce electricity?

Hypothesis

I predict it will take two or more lemons to create enough power to light up a light or power a small motor.

Results

I found it very difficult to produce enough electricity to power a light bulb or motor. I was able to get a voltage reading on the multimeter and get a very dim light from a LED bulb. I started with just one lemon and added up to five, which allowed me to get the light to work for a few seconds.

Conclusion

I predicted that lemons could create electricity. Upon further investigation, I found that they could in fact produce very small amounts of electricity. I found that there was enough electricity to power a very low voltage flashlight bulb when enough lemons were connected together.

HOW WALLRUSES GOT TUSKS!

HOW WALLRUSES GOT TUSKS!

Long ago in the freezing land of Marblesmarble with big icy mountains and giant raging snow storms lived thousand of solid oak brown walrus’s .One day a little walrus got brought into the world. He wasn’t like the other walruses he wore a silver colored coat of hair and thought he was a elephant because he wore less fur than tons of the other walruses also he had a bit of along nose. His mom and dad called him Hairy.

One day when he was about 11 years old Hairy wondered why he didn’t have tusks like the elephant in his mom’s book she read to him. So he decided he would travel to the land of the elephants Hubaballooba. Hubaballooba is dry and scorching hot with just a couple of pieces of grass and not a lot of wildlife also with burning sand. Hairy went there to ask the elephants there how to get tusks.

One night when Hairy reached Hubaballooba Hairy spotted an elephant and crawled over to it and asked it why don’t I have tusks? The elephant replied you need to drink from the ancient water hole. So he did as the elephant said and while he was going back to Marblesmarble he grew tusks! He was so excited he couldn’t wait he went as fast as he could to tell his friends and family the news. When he got back to Marblesmarble they where amazed! They loved them so much they all drank out of the ancient water hole and they all grew tusks and that is how walruses got tusks!

Being a Baseball


I may be described as cold, and snow white with a lot of scary deep red stitches on the outside. I am also said to be extremely firm, but I believe I have a tiny bit of softness inside if you squeeze me hard enough.

The best part of being a baseball is twirling wildly as I soar through the air faster than a speeding bullet. The worst thing is getting cracked up side the head by a bat time and time again. It feels like someone took a steel pipe and smashed it against your skull. Then if that’s not bad enough, I fly into a hard leather glove and it’s so hard it feels like your diving into a cement pool. If you were ever thinking about becoming a baseball you might think twice. Why do you think we have all those stitches anyway?

Why I Am Proud to be an American

Homework Summary:

I am proud to be an American. We are blessed with so many freedoms. We are fortunate that we can vote freely and do as we please, yet, still today other countries do not have such rights and freedoms. In other countries people can not vote and do not even know what their governments are doing! I know that I will always have freedoms in America. I have privileges like the freedom to go to school, religion, speech and press. When I am eighteen I will still have those freedoms and much more, such as the right to vote. I am thankful that I have so many freedoms but sometimes I feel bad for the citizens of other countries who do not have it as good as we do. I think that without our freedoms America would not be what it is today. Freedoms are part of why people from other countries struggle to get into America. One reason why we have so many freedoms is because of our democratic system and how it works to ensure our freedoms in America.

I am also extremely proud to be an American because we live in such a diverse place. We have people from all over the world that visit and live here, like Spanish, Chinese, Australian and German just to name a few. All of these people are here because we have such a wonderful country. Finally, I am proud to be an American, because we have plenty of material possessions. We have so much wealth and opportunities while other countries are poor with very low amounts of water, food and shelter. I am truly lucky to live here in the United States of America!

How to make Smores quick and easy..


I made these Smores with a microwave. If your a kid like me, if your parents let you, you can make these Smore snacks quick and easy.
First you gather the ingredients.
Which are graham crackers, marsh mellows, and chocolate candy bars.

Second, you take out 2 graham crackers, 1 marsh mellow and a small section of chocolate candy bar from their packages.

Then, stack them with a graham cracker on the bottom. Then a piece of chocolate bar, marsh mellow, and another gram cracker on top.

Next, you place your smore on a microwave safe plate. Place it in the microwave and cook it for 60 seconds.

Finally, take out it out of the microwave and enjoy!

Last but not least. Do you know why they call them SMores?
Because after you eat one, you want Some More!

Welcome to the World of some Smart Kids.

Hello, welcome to our website, the World of some Smart Kids, maybe, guess that's a matter of opinion. Encouragement helps.

This is my first post and contribution to our website. Smart Kid World is designed, maintained and published by my brother, sister and myself. We are students, just some kids putting together a website for the first time. Actually, our dad gave us this idea of making a website. It's so that we can take our ideas and share them with other kids, or anybody that is a student or wanted to read some really interesting stuff. Plus it's really cool just to have a website that is yours that you can be proud of because this is our original work that we made.

I don't know, but as a student we are always compelled to write, read and share our opinions. We do lots of book reports and projects in school, they are not our favorite things to do, but with some creative thought, we can make them fun and interesting. Creativity makes learning fun.

Cheers to all the kids out there - here's to the future.
