Inventions and Technology

You are working hard to create a machine that could bring messages across the world using electricity. You take a metal wire and insert it into a rumbling machine that is connected through the wall into another room. All of a sudden you realize that you can hear things from when your helper clicks into the machine! You just invented the telephone! Who invented the typewriter? Who invented the iPad? I am going to address inventions, jobs, pollution, and more detail about history’s greatest inventions.

Inventions

Alexander Graham Bell invented the telephone, with the help of Antonio Meucci, Charles Bourseul, and Elisha Grey. it was designed by using a straight string to carry messages long distances. You’re probably wondering, who invented the tablet? Bill Gates, the leader of Microsoft, developed the tablet a decade before Steve Jobs developed it. Last, the typewriter was invented by Christopher Latham Soles, in 1819. He had the help of John Pratt, Samuel Soule, and Carlos Gladden. It worked by stamping ink onto the keys, and then when you pressed a letter, it pushed down on the paper.

Now, as technology evolves machines get more and more sophisticated. Now machines are taking over labor and jobs. Here are a few examples of what they do. If there are many people doing similar jobs, the owner can produce a programmed production line, (PPL) to automate their jobs. That way, the company pays less money to workers. Also, if someone got a letter saying “Urgent. What character do I do for my biography report?” Instead of making another letter that might take weeks to reach them, you could just e-mail them the answer. And, sometimes people have to get together in one location. Instead of doing that, you could just turn on your computer and video conference whoever you need to talk with. Then, if you feel like you don’t have enough friends, or aren’t social enough, you could go online and visit a website like Facebook or Twitter. Last but not least, teachers are using technology to educate students. A Promethean board in your classroom is a good example. Now, technology is looking for more ways to stop pollution.

Pollution

Now technology has its good side, but it also has its bad side. As we create electricity, the power plants let out all the exhaust that was created. This is creating too much pollution. If you look at the big picture, of how many power plants and other pollution makers there are in the world, you MIGHT start to see the bad side. Also, when companies dump their waste into the river, it not only causes water pollution, it wastes drinking water. Just imagine what you swim in when you go to the beach! A few example of smog disasters is the Great Stink, in London, and the Great Smog. Did you know the most polluted place in the world is Chelyabinsk, Russia?

Now you see, technology is making people lose jobs. We have to teach the people whose job was eliminated to do other jobs.

3D Printed Prosthetic Hands

3D printers can make prosthetic hands.

What if you were born without a hand? Would you like one made by a 3D printer, maybe even one made out of plastic in the colors and  design you pick!!! Did you know that amazing prosthetics are being made from a 3D printers? 3D printed hands may seem very different from real hands, but in several ways they are alike.  They can make a kid feel almost normal like Kieran.

3D printed prosthetics are more advanced than they ever have been before. Did you know the original first printed hand was only a pair of hooks held together by a rubber band on a prosthetic with only zip ties holding it together? The 3D prosthetic hand is made up of a polymer called Nylon 12 [plastic melted]. They can be made in fun color combinations and designs that look out of a Superhero movie, like in this video.

3D Prosthetics are held together with nails and wire, they are also held together by elastics, pins, and  hinge caps. A design that anyone can put together, even YOU!

It takes about 20 to 30 minutes to print a 3D prosthetic hand although about 4 hours to assemble. About 4 hours per hand with the cost of only about $35 to $45. Materials cost about $45 altogether. Much more affordable than the electrical prosthetics.

Here are a few ways you can get involved: You can collaborate with others by sharing your tools (software) and knowledge. You can also purchase a 3D Printed Hand Pro and 20% of the net proceeds will be used to help different schools print and create 3D hands to be donated. In addition, you can download the file and find an e-NABLE a global community of volunteers and start 3D printing now.

Killer Plants

Some carnivorous plants are like mazes that lead to a dead end. Some are like ticking time bombs. Others, just swallow creatures whole. When I first started researching about carnivorous plants, I thought I already knew a lot about them. It turns out that while I am learning about these plants, I can’t stop thinking about them because there is a lot more to be discovered. Imagine a fascinating, beautiful plant living in a boggy swamp and getting its nutrients not only from soil, but mostly… from meat! Dun, dun, dun!

There are 630 different kinds of carnivorous plants around the world. Some carnivorous plants are aquatic and others live in the soil like most other plants do. They live in poor, wet soil that doesn’t have a lot of nutrients. Because the soil doesn’t give them the nutrients they need, they’ve adapted by eating bugs or small animals. Carnivorous plants are divided in five types, according to how they can catch their prey (food): Pitfall Trap, Flypaper Trap, Snap Trap, Bladder Trap and Lobster Trap.

This carnivorous plant is called Monkey Cup because monkeys drink the water in it.

The Pitfall Trap plants have slippery leaves that are shaped like a funnel and slant down toward their bottom. When bugs land on the leaves of these plants, they slide down the leaf into a “pool” of digestive enzymes found in the bottom of the leaf. Monkey Cup and some bromeliads are examples of Pitcher plants and some are so large that they can catch and consume rats or frogs.

Pitcher Plants have a mechanism that they can turn on and off throughout the day. Part of the day, the Pitcher Plant’s edges are dry so when a scout ant comes and smells the nectar, it goes back to its colony and brings some of its friends. But by that time, the plant is wet and the ants fall into it. The Pitcher Plant gets an ant feast! If the Pitcher Plant was wet all the time, the one scout ant would slide down and not go back to the colony to bring the other ants, which means that it wouldn’t bring back all the food. Insects cannot escape Pitcher Plants, with their pitfall hunting mechanism.

The Sundew plant uses a sticky substance to hunt. It is a “flypaper trap” plant.

When bugs land on a Flypaper Trap carnivorous plant, the sticky substance that appears to be dew when it sparkles on the sun keeps bugs from being able to get away. When the bug struggles to escape, it gets even more stuck and the enzymes on the plant’s leaf digest it faster. Flypaper Trap plants are impossible to escape. Sundew and Butterwort are a couple of carnivorous plants in this category. 

Carnivorous plants with Snap Traps catch their food by trapping bugs or small animals inside their leaves so they cannot escape. All of you might have heard of the Venus Flytrap, but did you know that if the prey touches one of the hairs on the leaf it will set a timer? If it touches another hair within 20 seconds, then the plant will shut; otherwise, the prey will be safe. You can probably make a Venus Flytrap close its jaws with a stick, but it has to feel the prey struggling to start its digestive process. If the object isn’t food, the trap will reopen in about 12 hours and “spit” it out. The Venus Flytrap can only close its mouth six times in its lifetime.

A Venus Flytrap catches a lizard.

After capturing an insect or animal, The Venus Flytrap shuts in less than a second. “All of this takes about 1/2 second,” says Julia Cooke, a plant ecologist from the Hawkesbury Institute for the Environment at the University of Western Sydney, in Australia. But other carnivorous plants can move even faster: “The related Waterwheel Plant uses snap-traps, but underwater. This plant closes its traps in 20 milliseconds, making it one of the fastest movements recorded in plants.”

The Bladderwort is a type of aquatic carnivorous plant.

Carnivorous plants with Bladder Traps, like the Bladderworts and the Pinguicula, live in the water. They suck bugs and other small animals out of the water (like a vacuum cleaner)and into the bladder so they can be digested. There is no escape. 

The Cobra Lily uses the “lobster trap” mechanism to catch prey.

Carnivorous plants with Lobster Traps use tiny hairs which are all going the same direction to force bugs to walk toward the bottom of the plant’s leaves. The Cobra Lily and the Corkscrew are types of Lobster Trap plants. There are mazes inside them that are easy to enter but hard to leave that they use to catch prey. When the bugs hit a “dead end” with a pool full of digestive enzymes, they can’t escape.

I never knew that carnivorous plants were so interesting and that they were divided in five categories based on how they eat bugs and animals. They are beautiful but dangerous, inviting but deadly. Not to humans though, so don’t be scared if you see one in action. I hope you do.

Supersonic Transit System

Not long ago, billionaire Elon Musk had a vision of the future. He dreamed of a supersonic transit system. Soon after, he released a 57-page document on a concept called Hyperloop. Hyperloop is a huge supersonic transit system that travels in between cities filled with traffic. The sponsor of Tesla motors and SpaceX dreamed of a friction-less, low-pressure, vacuum-sealed pod. Powered with energy from solar panels, it should be able to withstand major natural disasters. Elon believed this pod would shorten travel times drastically. For example, the distance from San Francisco to Los Angeles takes 6 hours. This pod could get there in 35 minutes.

NASA Makes Pumpkins

I read a great article on Dogo News about how NASA scientists carved pumpkins. That was the challenge posed to the excellent scientists at NASA’s Jet Propulsion Lab in Pasadena, CA in 2010 during Halloween. This interesting competition has turned into an annual tradition with partners trying to outdo each other with sky-high hi-tech carvings.

This year’s entries included a Pac-Man pumpkin, a replica of Darth Vader’s meditation chamber, a carousel, a Ninja Starshade, and even a sink hole pumpkin. While the creations are certainly quite strange, what is even more so, is that the engineers-turned-artists had just an hour to complete their masterpieces!

And now, watch this epic video. Continue reading “NASA Makes Pumpkins”

Have you ever wondered how a computer works, how it programs, and how it Hour of Code is a great way to learn how  a computer works. Hour of Code can show young kids how to code and makes the brain work harder too. It’s amazing! Besides amazing, hour of code is very challenging. And it can push you, some are really easy but it pushes your brain to work harder and will also make you smarter!
Most kids in the summer are just really lazy in the summer and mostly just watch TV. But instead of watching, you should be challenging your brain with the hour of code. Then in next year you can have a higher chance of getting good grades for their school work. It can create a “new” world in the computer. There are many versions that you can play. For example, there is Minecraft, Star Wars, Frozen, and Angry Birds. And much more to Hour of Code actives.

Drones Stink!

Phone the Drone Ars Electronica Center via Compfight

By Ava    

Lots of people are thinking dones are fun so they want to buy drones but we need to get them under control. Thieves can use drones to spy on other people. Drones are very expensive. Drones are also taking over jobs that people do.

How would you like it if someone broke into your house? Well now they can with drones. Right now a drone could be spying on you and in a matter of minutes someone can break into your house.

Some drones can cost up to $150, $290, or even over $1,000. who would want a toy that would waste all of your allowance. Sometimes a drone will cost a lot of money but will break down, and will waste your money.   

Drones are taking over things that we do which is not a good idea because it will make people lazy and not wanting to do their job(s). Kids are going to soon have drones doing their homework, which will increase kids lack of smarts.

To some people a drone can be very disturbing, but to most people think drones are fun and good to play with. For drones there are more bad reasons than good, that is why we should ban DRONES from California.

Doomed Drones

   Ich habe heute leider keinen Titel für dich.Creative Commons License Chris Blank via Compfight

By Quinci

What is a drone? A drone is an aircraft that can navigate autonomously, without human control soas they will take people’s jobs, invade privacy , and they don’t carry much or go to far also they are dangerous

Drones shouldn’t be for delivery because it can be dangerous to planes.In the spring of 2014 a 375lbs drone that was flew by the Pennsylvania Army National Guard crashed outside of a elemantry school in near Harrisburg, Pennsylvania, school was out so no body was hurt.

Drones invade people’s privacy.There was a lady sunbathing topless in the privacy of her secluded backyard near Melbourne, Australia and a drone, hired by a real estate agent to take photos of the property next door to her house was, and making a buzzing sound. Later she was horrified to discover a picture the drone had taken, showing her mostly naked body was in billboard real estate ads.

Drones don’t carry a lot and only so go far.drones can only carry up to 5lbs, that’s only 86% of Amazon’s deliveries. A test shows that it can will only go 10 miles said Bezos. Their lithium batteries can only last 2 to 3 year, also their  batteries can explode and blow up your package and the drone.

If we have drones people will be losing their jobs because the drone will deliver your packages not the mailman, Over 500,000 drones have been sold.There are many people that have jobs caring packages where will they go , WHERE WILL THEY GO!

On the other side they can be handy, fast, and can fly and that means it can beat traffic.Thousands of drones are taking over the skies and need to be contained so drones so not be for delivery. They will take people’s jobs, invalid private , and they don’t carry much or go to far.

Do elephants have emotions?

Elephant (Loxodonta africana)Creative Commons License Bernard DUPONT via Compfight

Have you ever wondered if elephants have emotions like humans do? Scientists say that they have many of the same emotions that human have. They can feel sadness, joy, love, jealousy, fury, grief, compassion and distress. And when one elephant is scared by something another elephant would calm it by touching it with it’s trunk. Elephant can also miss each other when they are not together or when the are separated. Two elephants, Shirley and Jenny, were reunited at a sanctuary in Tennessee after more than 20 years apart. they locked trunks, did a giant, elephant size hug. The even bent the metal bars of the gate that separated them to get closer to each other. Elephants can also help each other to get something they really want. They can also comfort a mom that a loss her baby. Elephants are even the most emotional species in the animal kingdom. These big animals have many emotions to express their feelings with.
