Hey guys! Today I have a new post. Please enjoy!

How to make an Earthquake-proof Building

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In order to have an earthquake-proof building, it needs to have strength, flexibility, and vibration control. To have a strong building, you'll need to have a strong material, like concrete. Concrete is a strong material, but it can shake apart if an earthquake were to come along. You would also need a flexible frame to have the building bend and sway with the earthquake. Steel is a very flexible metal, it's used in frames on buildings in earthquake zones. The building needs vibration control to be complete. Without the vibration, it would survive only a short time in an earthquake. The building needs to respond to the shaking and transfer most of the energy back to the ground and keep it from shaking a lot. Reducing the shaking of the building helps too. That's all you need to make an earthquake-proof building.

THE EARTHQUAKE DETECTOR
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Once upon a time, there was a polymath named Zhang Heng who lived in China nearly 2000 years ago. He invented the first ever earthquake detector, AKA the seismometer. It was made with a pendulum that swung in the direction of an earthquake. Wherever it swung, it would knock a ball out of one of the eight dragons mouths and into a toad's mouth below. Whichever ball dropped, that way was where the earthquake was. One day, he decided to take it into court. His rivals weren't very hopeful about the device. One time the device went off, but no one felt a thing. They all laughed at him! Later, someone came by and reported that an earthquake happened at the exact place the detector said it would.

 Hi guys! I have a new post today about my speed video for the shake table.

                            

 Surviving an Earthquake- TAIPEI 101

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A building that survived many earthquakes and is the tallest building in Taiwan is called Taipei 101 (Center). It's over half a kilometer tall. The building is famous for the damper (Left) on the inside of the building. A damper is a ball that reduces vibrations in an earthquake. Without the damper, the building would shake apart. I made one out of washers for my building. It reminds me of a pendulum that moves the opposite way the building is moving. The damper is nearly 1.5 MILLION POUNDS!!!! There are also cables suspending it that are more than 3 inches thick, and pistons that support the bottom of the damper. The pistons also act as shock absorbers. The damper is so famous, it has it's own mascot, the damper baby! (Right)

Konichiwa! Today I will be talking about some of my activities I did.

DANCING PUPPET
~~~~~~~~~~~~~~~~~~

This activity has to do with levers. What I needed was....

- Cardboard (I got some from a soda box.)

- Markers (Black, White, Red, Purple.)

- Scissors

- Paper Fasteners

- String/Yarn ( I used thread.)

- Tape

- 4 Pennies

I cut out the shape of what I wanted my puppet to be. The puppet I wanted to make was the Marionette from the game Five Nights at Freddy's. I cut out the shape of the puppets body and head, and decorated it. Then I cut out the arms and legs out separately and colored them in. To make the arms and legs move on the body, I taped a piece of  to the side of the arm that connects the arm to the body. I did the same thing to the other arm and the legs. Taking the 4 pennies, I taped one to the end of each arm and leg. Then I poked a hole in between the string and the penny for each arm and leg. The hole had to be closer to the string than the penny. Then I connected the arms and legs to the body with a paper fastener. To make the puppet dance, I just had to pull the strings.

How does it work? The arms and legs are like a seesaw. AKA a first class lever. The fastener is the balancing point, the penny is the load, and the string is the effort to lift the penny up. Easy!

FLOATING PING-PONG BALL

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This project was really simple, all I needed was a hairdryer, and my ping-pong ball. I put my ping-pong ball on the hairdryer and switched it onto normal. There are two things that are making the ping-pong ball float up. It's gravity and the air coming from the hairdryer. Gravity pulls down the ball and the air pushes it up. That's air resistance at it's work. If the pull of gravity and the push of the air are equal, the ball floats!

MARSHMALLOW SHOOTER

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Shooting a marshmallow? Are you sure that you can shoot a marshmallow? You can! With these items....

- 2 Toilet Paper Rolls
- 2 Rubber Bands (Thin)
- Pencil
- Duct Tape
- Hole Punch
- Scissors

I took my first toilet paper roll, and cut a straight line lengthwise down. Then I overlapped the roll to make it smaller, and taped it together. For the handle of the launcher, I punched two holes aligned in the top of the toilet paper roll, and slid the pencil in. Now that I'm done with the first roll, it's time for the second roll. Taking the scissors and the toilet paper roll, and cut two slits into the top of the roll. I did the same for the opposite side. Then I took the two rubber bands, and put one on each side. Taking tube 1, I slid it into the bottom of tube 2. To complete the launcher, all I had to do was slide the rubber bands on the pencil. I didn't have any marshmallows, but I did have mini ping-pong balls!

All I had to do was load a mini ping-pong ball into the launcher, pull back the pencil, and let go.

 Hey guys! Today I have a new post about trebuchets. I have a speed video for making the trebuchet. Then I'll talk about levers and their classes.

SPEED VIDEO: TREBUCHET

~~~~~~~~~~~~~~~~~~~~~~~~~~

NOT SO SIMPLE MACHINES

~~~~~~~~~~~~~~~~~~~~~~~~~~

Have you ever used something like a spoon to pry open some sort of container? If you've done that before, you used a lever! From tweezers to a broom, there are many different types of levers that are used for different things. They are very useful because they help do things people can't do, like crack a nut. If you are on a seesaw, and somebody bigger than you gets on the other side, he goes down, and you go up. How can you make him go up? Good Question! If the balancing point was closer to the bigger kid, you could lift him up easy as pie!The first person to figure out how to use a lever was a mathematician known as Archimedes. He was also a scientist, inventor, and engineer. One of his sayings was....

"Give me a firm spot on which to stand,

And I shall move the Earth."
 

You can lift almost anything with a lever, the further the balancing point is from you, the easier it is to lift an object. There are different levers with different jobs. I'm gonna talk about 3 lever jobs.

LEVER JOBS

~~~~~~~~~~~~~~

Some levers have a job for lifting things. Have you ever tried to lift 3 books with one finger? I know that it hurts! With a couple of pencils, you can lift the books with little effort! You just need to position the pencils like a seesaw.

Do you have a nutcracker? I do, and I know that nutcrackers are levers with a job for breaking things. Try cracking a nut faraway from the hinge. Now try it with the nut close to the hinge. What's the difference? Leave your answer in the comments below.

Last is the most common job for a lever.... moving things! Your arm is a lever! Put your elbow on the table and put your finger on your hand, then move your hand upward. Your hand moved your finger a lot! This is an example of your arm being a lever.

These levers belong to 3 different classes. The 1st class of levers is like a seesaw. Your effort is on the left, the load is on the right, and the balancing point is in the middle. The other two classes are way different. For the 2nd class, the effort is on the left, the balancing point is on the right, and the load is in the middle. Last, but not least, the 3rd class. The 3rd class is like the 2nd except the load and the effort switch places. Those jobs aren't the only jobs that people need help with. There are many other jobs and levers out there. Like builders say, "You need the right tool for the job!"

Class 3 is set wrong. Sorry.

Star of the Show! : Part 2

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

 Hey again! Today I have two more stories and a special experiment.

This story is from Lakota Sioux, North America. It's called "Fallen Star and the Hand." Once upon a time, there was a Chief of the Lakota Tribe. He was a very selfish leader and didn't care about his people. So, the gods made the people in the tribe rip off his arm. His daughter was really upset because her fathers arm was ripped off. She declared that if anybody found the arm, she would marry him. The person that found the hand was a young warrior by the name of Fallen Star. He married her and they lived happily ever after.
 I think it should be called "Fallen Star and the Arm."

This story is a interesting one. It's called "The Herd Boy and the Weaver Girl." Long ago, a Sky King created the heavens. He decorated it with stars, and had his daughter weave the clouds. She was really exhausted after that because the sky was really large, so her father sent her to play in the stars. When the princess decided to swim in the Milky Way, she saw a handsome herd boy, he was watching his water buffalo graze. She lost track of time and her father found out why. He flooded the Milky Way so she couldn't see him again. She cried and cried until her father made an agreement. On the seventh day of the seventh month of every year, he would send out a flock of birds to make a bridge across the Milky Way.
