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 ou...

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.

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.

TESLA MODEL 3 By Tej Mehta We have been waiting a long time for the new, affordable Tesla. Recently, thousands of people lined up to pre-order the 35,000 dollar car. Tesla said that each person would have to put down 1000 dollars to have it pre-ordered. According to Tesla, by April 15, they had reached almost 400,000 orders. The Tesla model 3 takes all the modern technology of Tesla's other cars, and puts it in a affordable, all electric car. The Tesla model three can go 215 miles on a single charge, and it can reach 60 MPH in under 6 seconds. However, that is not as good as the Tesla model S P90D, which can reach 60 MPH in 2.8 seconds! The Tesla Model 3 has all wheel drive, and a 15 inch screen . The model 3 is ultimately the Model S, scaled down in price, and it is not as advanced. But, it is still more affordable and will lead to Tesla making more money. Not to mention, it still does have the spice of Tesla Motors added to it! Elon Musk says that the car should have 5 star ...
