Alfred Bernhard Nobel

Alfred Bernhard Nobel was born in 1833 in Stockholm, Sweden and died in 1896. He was educated in St. Petersburg, Russia. In the 1860's he began experimenting with nitroglycerin in his father's factory. Finally he discover that a mix of kieselguhr and nitroglycerin was most effective and named it dynamite. He received a patent for it in 1867. Then later in his life he combined nitroglycerin with an explosive called gun-cotton that produced a jelly-like substance that was more even more powerful than dynamite. These inventions helped humanity because they reduced the cost of many construction work like drilling tunnels, blasting rocks, and building bridges back then. In addition, not only did Nobel invent explosives, but he also invented the Nobel prizes. As you all probably know, people have been getting these awards since 1901. This is all thanks to Alfred Nobel, who donated a $9 million dollar fund for the Nobel prizes as his last will. He meant for the awards to be given out when people made honored achievements and discoveries in physics, chemistry, medicine, literature, and work in peace that helped humanity. Overall, Alfred Bernhard Nobel was a very intelligent and generous man that should be honored for his achievements forever!

Worms

There are hundreds of types of worms, but they all fall under three main categories. These categories are flatworms, roundworms, and segmented worms. The flatworms are grouped in the phylum platyhelminthes. Flatworms can reproduce asexually. Also, they can regenerate, which means they can regrow their body parts. Therefore, if they really need food then they can eat their own body parts since they will regrow them back anyways. Flatworms are 5 cm. long and have linear symmetry. Another type of worms are the roundworms. They belong in the phylum nematoda. Roundworms are usually parasites that live on plants or other hosts and eat their blood and reproduce on them. Otherwise, they live on land or in water. In addition, they are usually about 5 inches in length. Lastly, there are the segmented worms that belong in the phylum Annelida. Segmented worms live in soil underground and can breathe through their skin. They have bristles on their segments to help them glide underground. Do you ever wonder why earthworms come above ground after it rains? well, it's because their homes are flooded, and they need moisture to survive. You probably also hate earthworms and think that they are slimy and disgusting creatures. But for real they are essential to a healthy garden and make soil rich for plants to grow in. After reading about all these types of worms which type do you like the best?

Stop global Warming-Take Action now before it's too late!

Stop global warming!

You can do so many things to help the world we live in from being destroyed. Do something to help. You can plant a tree, carpool when going somewhere, recycle, stop polluting, and stop using electronics all day. Don't wait for a leader take action on your own. Did you know that every second, an area the size of a football field of rain forest land is burned, bulldozed, and completely obliterated? At this current rate of destruction nothing will remain at the end of this century. Without any rain forests and trees there will be too much carbon dioxide in the world, then the the earth will grow warmer at an even rapid pace. So why is global warming occurring in the first place? Well, the earth is getting warmer because humans are burning fossils fuels, humans are polluting the air, and humans are clear-cutting forests. All the main reasons for global warming, as you must have noticed, are human activities. Therefore, global warming is occurring just because humans don't want to leave nature the way that it is. That is why we will be the ones who have to suffer, unless we do something about it. Unfortunately, we won't be the only ones to suffer, all land animals and several sea creatures will have to suffer along with us. In fact, an average of 137 species go extinct every single day and 50,ooo a year. Who knows we, humans, could be next. Already we are seeing the effects of global warming all around us. This includes several recent hurricanes, heat waves, more intense storms, the melting of ice in Antartica, warmer temperatures, more wildfires, and shifting wildlife habitats. The present has already happened but you can still change the future. It isn't just about you and your future it's about saving our planet from extinction.
Save the earth from being destroyed and take action now!
