                                         Let There Be Fire !!!!!!!!


Name of article: Why does Italy's Mount Edna keep erupting?
Source: for more facts about my article





Hey guys Thebestscienceblog 12 here and today I will talking about this eerie volcano found in Sicily,Italy.This article is about a constant erupting volcano that is terrorizing Sicily.




Mount Etna has been continuously been erupting in Sicily for the past 2,000 years. The last eruption was on November 28, 2013. The amount of lava that has been spewed can fill up the Chicago's Willis Tower ( the  former Sears Tower). 



Geologists are still trying to figure why this volcano erupts in so many different ways. Over the 2,000 years the volcano has been erupting in ways including quiet lava streams, spewing fire mountains, and even the dangerous pyroclastic flows(super heated mix of ash, lava fragments, and gases that run down volcano slopes). 










Geologists have come to the conclusion that when the magma deep below the volcano rises towards the surface it ascents at different speeds therefore effecting the eruption type. 

A fast lava ascent results in the lava keeping its air bubbles and making the eruption similar to that of a fizzy drink. While a slow lava ascent makes the magma lose air its bubbles resulting in lots of lava but little to no explosions.


I chose this story because I wanted to learn more and share about this interesting volcano. I predict that this volcano will keep on its current path and keep spewing lava over the Sicilian city. A question I have for you is in your opinion do you think geologists have the right reason for the constant eruptions or do you think there is a different cause for this? 

My opinion is that the geologists have the right reason for the cyclic eruptions.

                                              The mysteries of Algae


                      Do you know what algae is??
Today I will be talking about the plant-like protists called Algae. Algae are the things you see in the spring and summer growing on ponds, rivers, and sometimes even lakes.



Algae are similiar to plants in ways like that use photosynthesis to gain food and that most algae are eukayotic, meaning they have nuclei. They differ because they don't have roots systems, leaves, and stems.

The different types of algae are diatoms, dinoflagellates, euglenoids, red algae, green algae, and brown algae. I know that sounds like a lot but they are actually quite easy to explain. 

First I will be talking about the three types of algae. The most important is the green algae. Green algae makes up almost half of the world's oxygen and is the most common type with many sub species.

 Red algae is found deep under the sea and gets its food from photosynthesis. Carrageen, a substance found in red algae, helps make everday products like toothpaste and pudding smooth.











Brown algae live in the ocean and different types include seaweed and kelp.




Diatoms are gold brown in color giving them the name gold-brown algae. Diatoms are rich in silica which is a major ingredient in glass.

Dinoflagellates  have two flagella that help them move.  One acts as a belt while the other acts as a tail but they both rotate. Dinoflagellates are also available for red tide.  Red tide occurs when large amounts of dinoflagellates get together in the ocean.  This result in many deaths of fish from not getting enough oxygen.
Euglenoids have animal like features including flagella and eye spots that are sensitive to light.

Lastly some good things about algae are that they benefit humans in food and medicine. They also help by reducing harmful chemicals and carbondioxide emissions in the environment. In conclusion algae are great for you and me !!!!!

            Protists!!!!!! Read All About it!!!!!

Today I will be talking about these wonderful things called protists and more specifically protozoa. Protists are Single or multi celled organisms that live in wet environments. The three main groups of protists are animal like, plant like, and fungi like protists.

Protozoa are the animal like protists. The same characteristic all protozoa share is that they all are eukaryotic, their cells have a nucleus. Most of these species are found in wet environments including lakes, rivers, ponds, and even in tiny puddles!!






Scientists classify these protists by how they move. The four main types of protozoan are ciliates, amoebas, flagellates, and sporozoa.





Ciliates are the most complex protozoans.They have  two nuclei, the micronucleus and the macronucleus. The micronucleus controls reproduction and the macronucleus controls day to day functions.

                                                                                                                                                      Ciliates move by tiny little hairs called cilia. These cilia are most effective in water. 


  

Second I will be talking about amoebas. Amoebas move by  using temporary extensions of their bodies  called pseudopods meaning "false foot". They also use their pseudopods to capture food by surrounding it then capturing it. Many ameboids wear exoskeletons to protect their soft bodies.

Next comes the flagellates. Flagellates use a whip-like tail to move and capture food around them. Their tails only work in water so you will only find flagellates in water environments.

Lastly are the sporozoan group. Sporozoan are parasitic with  no means of moving by themselves for most of their life. They give no help to the host organism they are in and often hurt it.




Some diseases that are caused by protozoans are Babesiosis and Malaria. The commonly known disease Malaria is caused by a sporozoan spread through mosquito bites. Symptoms are aches, chilles, headaches and can sometimes result in death. Babsiosis is caused by the babesia parasite that is transmitted through ticks. This disease is common in the northen cities of the U.S including New York and New Jersey. Symptoms are nausea, fatigue, and weight loss.

Some positive things about protozoa is that they help keep down the bacteria population and that they help other animals survive by providing food.
