The science fair


                                                                                Photo

Well, the Science Fair took a long time to work on for me, but in the end it turned out good.  Now first, before I started on my Science Fair board, I needed to find out my topic by looking at everyday questions.

Once I found my topic which was "Can different types of foods create electricity", I had to build a hypothesis for it. That means I had to answer the question, then put why I thought that was the answer.

Also, I chose that topic because I was interested in electricity and wanted to create it.  When I put my hypothesis, I had to do some research about what question I was trying to find the answer to.

Now, the next thing I had to do for the Science Fair is to put the materials and procedure. That means I had to put the things I used to do my experiments and put how to do the experiment.  At first I didn't have the right materials, but I borrowed a voltmeter from my uncle who is an electrician.




The experiment got messy, but in the end I got the right results and did the right research to answer questions like, "What type of acids did all of my foods that I experimented on have?" The orange and lemon had citric acid, the zucchini had pantothenic acid and the potato had phosphoric acid.

Then, after I took pictures while I did the experiment, I wrote all of the results, hypothesis and other research down. Once I did that I had enough information to write my conclusion which is using the scientific method.

After I did my conclusion, I had enough information and pictures to start my display board. It took a long time to put all the information and pictures on there,but once I did that I had to put the title of the project on the board.

I also found out that if you had enough foods with a lot of acid and connected them with copper and zinc wires, someone would be able to power a really big electricity source.

After that I rehearsed presenting to the judges. I was really good at it, but I didn't want them to ask a lot of questions, so I rehearsed that too.


When it was time to present our Science Fair projects and while I was waiting for the Judges, I thought of ways of doing my presentation and to speak clearly.

When I was done I did good by speaking clearly, looking at the judge instead of reading off the board, explaining it clearly and thought the Science Fair was a good experience.

Mammals



Hey ,yeah I'm talking about mammals.  Mammals have mammary glands, that's what they use to feed their young milk.  Some mammals are monotremes like platypuses, sweat milk to feed they're young.

Mammals also have hair, backbones, breathe air, are warm blooded and have mammary glands.  Mammals are similar to birds because they both have back bones, breathe air and are warmblooded.  The difference is  birds don't have fur or mammary glands.

Placental mammals give live birth and feed their babies with milk. They also are the biggest group of mammals.

Monotremes lay eggs, sweat milk and they have different types of defenses.  The platypus has a poisonous tip on the side of their feet that they put in to predators when threatened.  Spiny anteaters roll in balls and protect themselves with the sharp points on their back.

Marsupials have pouches and leave babies in them while feeding them milk until they develop.  Mammals can also adapt to different environments by using their healthy body systems to stay active and survive.


                                                   My favorite mammal is the jaguar.



It is the only big cat that lives in the Americas and they live in rain forests.  They're near extinct and are relatives of the leopard.  They also live in large habitats and have a bite hard enough to go through a turtles shell.

The jaguar can weigh up to 211 lbs. and can have a length that's 6ft 4in. Jaguars also climb trees to pounce on their prey and eat large animals like bulls.  They also live mostly in south america and they use their fur color for camouflage.  They have adapted to swimming and eating fish.

John F. Kennedy and the civil rights movement

                                                             http://www.loc.gov

In the civil rights movement there were a lot of great people, but the one I'm talking about is John F. Kennedy.  He was a big part in the civil rights movement, he was one of the reasons African Americans we're treated equally.  He helped by giving African Americans federal jobs and ended home discrimination by allowing African Americans to buy better houses in the 1960s.

He also helped end bus discrimination by saying that African Americans could sit where they want.  He enforced laws against voter discrimination by motivating African Americans to register to vote and making proposals for African Americans that lead to the Voting Rights Act of 1965.

He also helped end education discrimination by enforcing the law of putting whites and African Americans in the same school.  He also helped end racial discrimination and thought all people should be equally treated.

A lot of African Americans didn't have as much power as other people, but because of John F. Kennedy every person today has rights. When I went to a history center I learned a lot of African American history like how a lot of blacks helped fight in the civil war and how there was a lot of people who helped in the civil rights movement.

He also made proposals that lead to something called the Civil Rights Act of 1964.  His civil rights proposals became law under the act and one of them was saying that all people should have equal access to public places.

birds


There's been a lot of animals I've talked about.  Now I'm talking about birds.  As you probably know, birds have feathers, but there are other special things about them like how they have two types of feathers.  They're called contour and down feathers.  Contour feathers are what make birds look smooth, sleek and colorful.  Down feathers give a layer of protection from a bird's skin and  keep birds warm.




Birds are also warm blooded or endothermic and their body temperature stays the same.  Each one of a birds' feathers is connected by hooks, so if one of their feathers get ruffled, they connect it back with the others.  Birds also constantly breathe through their air sacs to make them lighter and fly easier.

They also don't have any teeth, so they use their beak to tear the prey apart.  Some birds might not have beaks, so instead they have bills.   Water birds have these.  Bird's bones are hollow because if they weren't, they would be too heavy to fly.

They also have curved wings so air can lift them up from below. Also Georgia's, official state bird is the Brown Thrasher.

My favorite bird is the Peregrine Falcon. They can fly up to 202 mph and are also raptors.  That means they hunt other animals.

They eat mammals, reptiles and insects by diving through the sky and catching them by surprise.  They used to be endangered because of DDT, but they're not endangered any more.  DDT contaminated all of their food and put chemicals in lakes and plants.

They can live anywhere except polar regions, high mountains and tropical rain forests. It's also the fastest flying animal in the world. They live on scrapes or cliffs.

Reptiles

Hey, I'm talking about reptiles.  Yeah, like dinosaurs, crocodiles and snakes.  Some people think they're amphibians, but they're not because they can't breathe under water.They also have dry and scaly skin because they stay in the sun all day.

Some reptiles, like crocodiles and alligators, go in water but they stick they're heads out to breathe. They also stick them out to see their prey. They also have large scales called scutes.  They shed them one at a time.

.
Snakes are another reptile group.  They have different ways of catching prey. Some might use venom or swallow them whole.They also shed there skin all at once.They also have these things called pit sensors that can sense heat in mammals thats why they are able to know where the prey are when they're hunting. They  also  gluide they're called flying snakes.

Turtles are another reptile group.  There are different types of turtles like the sea, alligator snapping and the mud turtle. They also have huge scales called scutes and have to come up to surface to get some air to breathe.

Lizards are reptiles too.  They have to shed their skin in pieces.  There are also 3,800 species of them. Some lizards have detachable tails and can live on any continent except Antarctica because reptiles have to live in warm areas. They have to because they're cold blooded and need warm body temperatures.

year 2012



This year is going to be awesome!  I've already had an awesome 3 days and 2012 just started.

Winter break was good.  For Christmas I got gift cards, a remote control car and video games.

My Grandpa came over from Los Angeles to visit for Christmas and we had a good time eating and watching movies.


New Years was also good.  On TV we watched the ball drop in New York.

My friends and family celebrated in their own way.  We had a good time drinking champagne, hot chocolate and eggnog.


I hiked with my friends and moved into my new house.

Happy 2012, Bye!

Amphibians



Hey people! I know my last three posts have been about animals that live underwater, but now I'm talking about animals that can live on water and land.  They're called amphibians. Amphibian means double life because amphibians can live on land and water.

That's because they go through this thing called metamorphosis.  That's when they start off living in the water and breathing with gills as a tad pole.  When they go through metamorphosis they lose their tail, grow legs and live on land by using lungs to breath.

There's three types of amphibians. One is called arans, which are frogs and toads they can jump really high. Frogs jump higher than toads because toads are bigger than frogs.  Some frogs and toads have special ability's like poison, gliding, camouflage or seeming bigger by puffing up.

The second one is urodeles which are newts and salamanders. They have long flat tails, arms and legs.

                                                                                                                                                           

The third one is apodas. They're called caecellians because their look is like a snake or a worm, but they're amphibians and don't have arms or legs. They also don't see really good and light affects they're eyes so they stay underground.

That's the end... Bye.
