Introduction

How does clothing, paint, ink, plastic, fabric, cosmetics, food, and other materials get their color?  They get it from different types of pigments.  This article is going to let you know how green pigment was used to be made and how it is made now.
  1. Cobalt GreenThis pigment, was very expensive, and it couldn't tint well so is isn't commonly commonly used. It was discovered in 1780 because of the preparation of zinc oxide. You can make it using a 1 to 5, cobalt to zinc ratio.
  2. Copper Resinate  This pigment, was used from the 1400's to the 1600's. 
  3. Emerald Green This HIGHLY POISONOUS pigment was discovered  in 1808. It was one of the best pigments of the time, so they thought it would be best to kill people instead of having to "suffer" with bad paintings
  4. Green EarthThis pigment, is an all natural one with the elements iron, magnesium, aluminum, and potassium. This pigment is still in use today, even though it was discovered by the Greeks (circa late Greece). It was used a lot in the 1700's and since then it's use has gone down so this pigment will probably stop being used in the distant future.
  5. Malachite This no longer used pigment was discovered at around the time of Egyptians and was often used with green earth. It had an importance is the 15th and 16 centuries and was stopped being used in the late 1700's. Malachite is a natural mineral which can be ground and washed. You can't  find Malachite around here. If you wanted to make it, visit Madagascar.
  6. Verdigris This toxic pigment was discovered circa Middle Ages and is rarely used today.
  7. Viridian This very stable pigment can replace all greens and was discovered in 1838. It continues in use today because it isn't toxic.

Air Pollution (grade levels 4-8)

Air Pollution Next post in series Samuel Desai Many environmental activists, unlike me, like to say that pollution is an important issue. I prefer to categorize them into three different topics. Air Pollution, Water Pollution, Noise Pollution, and Light Pollution. The other types of pollution are for another week but don't worry, you will hear about them soon. You may believe that Carbon Dioxide (CO2) it the only pollutant, but it isn't. There are others. One type is methane gas, emitted by livestock and swamps. Another CFC's or chlorofluorocarbons which were used in refrigerators, hairspray, and many other things. But they were banned internationally in 2010 because of its deteriorating effect on the ozone layer. Personally, I think that the pollutant which harms us the most is sulfur dioxide. Sulfur Dioxide is a component in smog, but also reflects sunlight out into space, causing a global cooling. This may seem good, but sulfur dioxide is directly linked

Recently, the Tesla model X came out, and by recently, I mean yesterday! Elon Musk said this stuff on  twitter . With a whopping price of 130,000 and more it is very costly, but, the  car is great. The Tesla model X is a family friendly,  and and safe car. It seats 7, with 2 fold-able seats in the third row. The signature series, includes a 90 kWh battery pack, autopilot and self driving functions, and third  row seats. for 10,000 more dollars, ludicrous mode will be added to the X, making it go from 0-60 in  3.2   seconds!!!!!!!!!!!!! Also, for 1,000 more dollars, there is the subzero weather package, including heated steering wheel, seat heaters, heated washer fluid, and wiper defrosters. Also, for 750 more dollars, the car will be able to heave 5000 lbs. The falcon wing doors that the X has have sensors to keep them from slamming into walls, so it will stop at a certain point. I used Business Insider, and you can read the article  here. Check out Tesla's page while you'r

On No! Bees Are Endangered Because of Habitat Alteration ! By: Kaden Chien The IUCN has recently discovered a new Species of Bees called Bombus Fraternus. The Bombus Fraternus is a North American bee that is Endangered because of Habitat Alteration. This may be due to human activity such as Cutting down Trees or pollution. This species may go extinct in 80-90 years if this activity keeps up. Efforts to help with this species is going up. But what is strange is that where there are larger efforts, the population in those states are decreasing more than other states! The studies show that the c urrent range size relative to historic range: 71.38% and the  Persistence in current range relative to historic occupancy: 43.33% also, the c urrent relative abundance relative to historic values: 14.40% and lastly, the a verage decline: 56.96%.  If you want an image of a Bombus Fraternus you will see one down there: Now you will find the scientific classification of the Bombus Frat
