Science Experiment

So I think Science Experiments are fun. I have been watching a few of the them. One of my favorites is this. So what you need is

1 A straw with the wrapper still on.

2 Water.

So what you do first is take your straw and rip the two ends of the wrapper off. Then squeeze the two sides into the middle until they are very crinkly and can move no more. then slide the wrapper off one side of the straw but be careful to not let it get undone. Then set it on the table and get a bowl of water. Take a little in your hand, then let it drip onto the wrapper, TA-DA! Isn't that awesome it looks like it is growing, almost like a worm. And if you put a lot together they look like a lot of worms moving together.

Thomas Edison vs Nikola Tesla

So recently  I have been watching these american genius movies on Netflix and I think that they are really cool. One of them that I liked a lot was Thomas Edison vs Nikola Tesla. One thing I noticed about them that sometimes the inventor invents it but then another person makes them better, so this one is like that. So Thomas Edison had a shop and he had people who were making stuff and trying to make electricity in a light bulb. Soon Thomas Edison found out how to do it. He had invented the light bulb. He showed his people in his shop and they thought it was awesome but there was one problem. He couldn't put it into people's homes because there was no plug back then! So the there was another problem think of a power plant then Thomas Edison tried his bulb but it didn't go that far so it could only go to the houses right next to it. But then Nikola Tesla came around he was a young man and he showed Thomas Edison that he was very smart and showed him about alternating current. It could go to very far places like from California to Colorado. But Thomas Edison did not like alternating Current because it was way to dangerous. He told Tesla that if he found out to make his light bulb stronger then he would give him a lot of money. So Tesla sent off to work and after some time he made the light bulb stronger and went to Thomas Edison and asked for his money but Thomas Edison wouldn't give it to him, so Tesla ran away and found a really rich guy and he showed him his light bulb. The man liked it and would help him to make it better. So Tesla was making his with Alternating current and Thomas Edison wasn't so Tesla's was a lot better but it was dangerous so he started to use Transforming that we still use today. But after some time the rich guy was going to go bankrupt so Tesla Tore up all of his Patents and he died alone and without a penny in his pocket. We still use Tesla's alternating current today but Thomas Edison invented it.

Archimedes screw

So the Archimedes screw was obviously invented by Archimedes. It was used to get water from a lake or just water up onto plants. It works like this. Think of a spiral staircase, then think of you on the stairs, you are not moving, but then the staircase starts winding upward. Then there are these stoppers that don't let the water go down. Then at the top it lets the water out and keeps doing the same cycle over and over again. Archimedes was a famous scientist and here is a little story about him.

So the king during that time liked Archimedes a lot because he was smart and could solve problems for him. One of these problems was about a crown. He had asked one of his servants to make him a crown of gold. But he was worried that it wasn't all gold and asked Archimedes to come and solve the problem. Archimedes came but didn't solve the problem immediately, instead he went to his house to think about it. He was in his bathtub and then he saw how the water rose when he went in. 

"EUREKA!"he cried  and ran into the streets naked. He had solved the problem. This was called bouncy. You may have heard of it. This what he found out. He put a piece of gold the exact volume as the crown. The crown was more dense so it meant that it was not pure gold it was only leafed. 

The Pheoenicians

So the Phoenicians were really good sailer's that lived to the north of Canaan. But it was hard to plant wheat where they lived because it was all rocky and sandy and dry. So they used there boats and sailed the Mediterranean sea, and became traders. They started cutting down trees to build homes. The Phoenicians were famous for making glass. Making glass in the ancient times was a long hard complicated process. So they started out by making a chemical called lye by putting water on the ashes that were left over from the fire. Then they collected the liquid that oozed out of it. Then they mixed the lye liquid with sand and then put it over a fire to melt it and to get it really hot. But it was hard to melt sand so they had to use these bellowing machines tat got it really really hot which melted the sand. Then they cooled it down so it turned into glass. Other ancient people made glass so they weren't the first people who invented glass but they were the first who invented glass blowing. It works like this, instead of putting it into a mold they would put it into a pipe and then they would blow gently and it would form a bubble, then they could twist it. They also put dye into it so they could color it.

My Cakes

So I love baking and this time I wanted to try something new like Cake :). Well I thought that chocolate cake would be good. So I got a recipe on chocolate cake and I made it. I baked it I let it cool. Then I made the ganache for the cake. Me and my brother ran to the farm and got some cream for the ganache. I put some store bought chocolate and put it in a bowl but it asked for one pound of chocolate and that is a lot. So I had to make my own chocolate. But it still wasn't enough so I just thought I would half the recipe and only add one cup of heavy cream. But I messed up and I added two cups of heavy cream, how could I be so stupid :(. But then I thought of something brilliant. I would beat the heavy cream and chocolate into CHOCOLATE CREAM:). So I did that and it worked. I put it on the cake and I was so excited I had just saved my Chocolate cake:).
In the end it tasted really good.



So my brother is a real health freak, so he wanted me to make Kale Cake. Wow. So I made it the same as the chocolate recipe but instead of cocoa powder I added Kale puree which is just oil and kale blended together. I put it in the oven But i forgot that I had to put honey so quickly took it out of the oven and I scraped it back in to the bowl and added a lot of honey and put it back into the oven and let it bake, I had just saved another cake:). Well when it was baking I saw how to make a frosting but I couldn't find a recipe that didn't call for Sugar!!! But then at last I saw a page that told you how to make a egg white frosting. I was scared that we would get salmonella, It said that you would put really hot honey but I didn't want to put 1 1/4 cups of honey. I researched and I read that out of every 30,000 eggs one of them has salmonella in it but I still had a bad feeling about it. Well in the ending when I put it on the cake and I tried a piece it didn't taste thad bad but it was very sweet because of all of that honey I put inside of the kale cake, but it was good.

three types of tears

So there is a part of the eye called the iris.It cries all of the time. It cries around ten ounces per day, that is about 30 gallons of tears per year!! It has special glands. One of them is called the Lacrimal glands, they make new tears for the iris. She also has special tubes called Lacrimal puncta, they take out the old tears. So you know when you look at onion, well it smells pretty good right? Well when you take the first layer off a chemical reaction happens converting the suffoxides that make is smell so greatinto sulfenic acid which then becomes an awful substance with a very, very long name, syn-Propanethial s-oxide it stings your iris and it starts crying like crazy. And there is also emotional tears like if someone died that you loved or some one you love is going away.

Iris usually cries basal tears it is surrounded by a thin coating of three layers. That protect it from dirt a debris.

Rhinos

 Rhinos are the third largest land animal. There horn is made out of keratin. That is what are nails and hair is made out of. There horn is a very good weapon.They are nearsighted.Oxpeckers hang out on the rhinos back they eat the ticks on the rhinos back.The oxpeckers get there meal and the rhino gets cleaned it is called a symbiotic relationship.(They scream when they sense danger.)They weigh 3,000 pounds the third heaviest land anmal in the world.

Lizards and the draco Lizard

Lizards all have something in common some swim, climb, They are scaly, and they have claws. But the draco Lizard can glide. They are born on the ground, there instinct is to climb to get away from predators. They start with there face down to glide. Then they jump and wings come out from there sides Muscles pull on the wings and it makes it easier to turn, when it lands it swoops up so it doesn't just crash into the tree.

Crocodiles

The Nile Crocodile of Africa is over twenty feet long. For her nest for the eggs she first digs with her hind legs. She has 64 sharp teeth she has twice as many teeth as us. Step two lay eggs, step three buried eggs. When the momma crocodile sees a predator she chases it away. A full grown hippopotamus can chomp a 12 foot crocodile in half! Th crocodile is cold blooded. If the eggs are  88-90 degrees they are all boys if it is colder or warmer than that they are girls. Turtles sometimes lay there eggs where the crocodile layed her eggs because she knows that the momma crocodile will protect them from predators. When the baby crocs are done hatching they call for momma and when momma hears them she takes them to the water. (she takes them in her mouth to the water. She takes the baby turtles too.) Before the eggs hatched she protected them for along time and does not eat or drink.   

Duck Billed Platypus

The duck Billed Platypus is a mammal and it lays eggs! Their eggs are as big as grapes. When they are under the water the can not see, smell, hear, touch, or taste. They have a sixth sense. They have tiny sensors on their beak almost like the sensors on are hand. They feel tiny electric charges from objects and sometimes avoid them unless they are crayfish.

Worms

Worms have 137 segments. They have no eyes no ears no nose just a mouth. They have a lot of slim that helps them make tunnels the the earth like the ants. They are very good for gardens because they make the soil softer from those tunnels they build. Worms do not drown under the water. They breathe through their skin. Sometimes worms come out of the ground to eat, but usually when it is dark because then it is cooler  and more like the underground. The cells in the worms skin sense when the sun is hot, They need to be wet

Walrus, Polarbear, and aardvark

Walrus rule the water while the polar bear rule the land. The Polar bear can run up to thirty miles per hour. It has the biggest legs of all the bears. The Walrus's back flippers make them move forward and the side flippers help steer. There is a sack on the top of there neck the other side that it fills up with air and they can stay afloat.

Aardvarks love termites and ants they have a huge tongue too. When they smell something they like they dig it up with there claws. They have amazing smell and good claws to dig with. After aardvarks dig a burrow  they leave an make another one when they leave other animals take those spots. Like wort hogs, hyenas and other animals. The aardvarks tongue is 12 inches long! each time it licks at termites or ants it picks up close to 100 of them. 

Bees

Not all bees produce honey. There are thousands of species of bees but less the a dozen produce honey. The European honeybee is the most common. There are so many species of bees and they all share something similar. There are three parts of the honey bee, the head the thorax and the abdomen. In every average hive there are 30000 to 60000. A bee can not live without its colony. There are three kinds of bees in the nest the workers the queen and the drones. The drones don't do much. They fertilize the queens eggs and they can not sting and they can not feed them selves, at the end of summer the workers force the drones out of the nest and they die. The workers make up most of the population they are all female the only males are the drones.  The workers make the nest out of wax that comes out of secreting glands from the abdomen. The make the hex structures that honey pollen and eggs go into. They eat the pollen which gives them protein. The queen lays about 1500 eggs a day! The only thing she eats is royal jelly. She has a smooth stinger and she can sting as much as needed.  The worker bees sting to keep predators away from the nest, but after they sting they die.

Gem and mineral show

This is a picture of my last gem and mineral show these are the rocks i bought.
 This is a picture of my gold flakes below.

These gold flakes are from Brazil 

It has to sharp things on the sides.

This is a shark tooth. I think it is awesome.

It looks grown what do you think?

This rock i think is grown. But it is still cool.

This is my copper tin. It is bended right now. It can bend because of the tin inside of it.

This is the copper flat.

This is an awesome rock, It is called Azurite. It is originally 45$ but i got it for 10$. 

This rock looks like silver. It is the same as the one on top originally 45$ but got it for 10$.

These are pictures of rocks that I got on the second gem an mineral show.

Hot and Cold

Do you know why your teeth chatter when you are cold? Its because are body tries to keep it 98.6 degrees. When your body gets colder than that, your brain gives a message to your muscles to start shivering so it will warm up and your teeth start chattering. 

When you your body is too hot, then your brain tells your skin to start sweating. The sweat cools us off in two ways:

1) It Evaporates and carries the water that got heated from your body and it takes away the heat.

2) When you sweat and the wind starts blowing the sweat it acts like an air conditioner.

When you sweat you lose water so you should keep drinking since our bodies are 60 percent water.

Projects I've been Working On

My brother and I have been working on projects on DIY a fun site where you can do projects and share them and get badges if you master certain skills.

My profile is available at https://diy.org/sandman7 to see what things I've been working on.

Skeleton and Muscles

Today I learned about muscles and the skeleton.
Here are some interesting facts:

Did you know that your biggest muscle was your gluteus maximus which is your rear end? =

My nose is not made out of bones. It is softer and made out of cartilage.

Newborn baby's bones are all made of cartilage.

Your strongest muscle is your tongue.

Your biggest bone is in your leg it is called a femur.


The smallest bone is in your ear.

The blood in your body isn't made in your heart or brain. It's made in your bones.

I like to flex my biceps and I learned that muscles have to work in pairs so that if you flex one the other stops flexing.
