Current event 7: Charged cars that would charge.

Charged cars that would charge
science news
March 10,2010

In the middle of February, Tom Gage was drove his car into a building in San Diego but he didn't crash his car, he was showing it off to people on the street and then a bunch of people crowded around the car. Gage's car is not a normal car it is on the is electric and you plug it into the wall, and right now usually people use gasoline or diesel. The car uses gasoline and electricity, the electricity is being provided to the car by this hug batteries in the car. Now car makers are trying to make cars that are electric cars that are really cool looking and that are affordable and make people happy.  

When Gage is not driving his car he plugs it into a special meter that is connected to a grid and that grid is connected to a power cable and power station that is all over the United States that provides a
electricity to anyone in a particular place. Gage's has an idea that if enough people use the car, their batteries can be used to give the grid an extra boot. And then the cool thing is that when you give the grid power, when your car is low on battery the grid can give it more battery.  

I think that it is so cool that the car can be controlled by electricity and that the car can be re charged when low on battery, I thought thought that if the people who made the car make a commercial, then people might by it and they put some good info in that commercial. So i thought it was cool and that people should like it.

Footprints in science!

Sustainability means, a person that can last for a long to or period. A way that I can lessen my footprint is by  eating foods that are sold locally and not eating foods that are from other countries like Brazil for fruit and Argentina for Coffee, another way i can lessen my footprint i could not use the car for short distance trips i could ride my bike or walk to that place. A human footprint is, a impact that you have on the earth. I think that the video was trying to make people stop using so much stuff that they dont need to do like eating food from other countries and using a bike and not a car. They were trying to reduce pollution and the amount of gas that is used for no reason.

A ecological footprint is a tool used to measure and understand how much nature we have and how much nature we use. Earth has a lot to do with our footprint, It could make electricity go away which means no TV, Facebook and no cell phones, if we dont eat local food and only food from out of the country we would lose the food in our country, If we dont take care of out garbage like recycling it then all the garbage would pollute our water and our whole earth, and finally if we dont take care of the amount of water we are using then it might all be gone because if you leave the water on while brushing your teeth you are wasting water, if you take really long showers just for the heck of it you are wasting water so we must look out and monitor the amount of water we use. Something that makes an Eco footprint is what your impact on the earth, like running the water when brushing your teeth another one is when you leave all the light on when you dont need it.

Our family footprint would be:

  • We turn off the light when not needed.
  • We dont leave the water running when brushing teeth nor taking a shower.
  • We also turn down heat during the night not to waste fuel.
  • We bring our own bags to the store so that we dont need to get new bags.
  • And some of our family member do flush the toilet which is saving water (SOFIA) 
  • We wish that Serbia and other countries would make it easier to recycle paper and plastic bags.
  • When going on short distance trips we use bikes or we walk when ever  possible.

Roys problems

Today Roy has lost his speech and debate paper, that means that we are DUMBED in the compensation!    

Current event 6: Got milk? How?

Got milk? How?
Science new for kids

A group of scientist are looking at milk and why it was made. These scientist are going back thousands of years back when people could only get milk by squeezing cows, horses and other animals milk sack. They are looking who was the first milk drinker, and they are using there questions to guide them, for example;  why do so many people today still get sick from drinking milk? 

The scientist say that finding out about milk could also help answer, how did they keep the milk good and drink able with out refrigerators? Investigator and detectives are also trying to figure out about milk and they are using more then one method. They are also trying to figure out how the people could digest the milk. Mark thomas says that, "Milk was probably the first superfood" he also says, "having the ability to drink milk is remarkable."

In the US most people drink cow milk, but in other countries people mostly drin k goat, sheep, camels and horse milk. Mostly in Northern and Central Europe are able to drink milk. Unlike in Africa, Asia and southern America they dont eat or drink dairy product because it leads t diarea and other stomach problems. 

I think it was fun learning how and were milk started and who and why people cant drink or eat dairy products. I never new that milk was so hard to drink for some people because i would think it would be easy because it is a liquid and it isn't that har to drink it and it just goes strait down.   
   

Current event 5: When frog gender flips.

When frog gender flips
Science news

In California a student from a University is checking on frogs every day and one day he found a very unusual behavior between the frogs. He found that when he first started examining this group they were all acting or are males but now some of the frogs are acting like females. The students think that, there is a chemical in the tank that is changing them. The thing is a weed killer called atrazine, and ever since the frogs were birth the frogs have been living in this tant with this water. 

A student says that 30% of the frogs that were born there they were male and those guys were atrazine and they turned into females, and they are somehow sending a signal to males to come and mate. This weed killer that the farmers spray it goes don the plant and then affects the water and it drifts down it and then stays of the surface and then it affects the frogs. 

The students say the 40 of the frogs that live in the water have atrazine and that before they turned into girls the frogs already had girl hormones. 

The students say it is important to know how chemicals can affect an animal. 

I think that this article was super interesting and that it would help people learn in science and help them learn about how a frogs life works. I also liked in this article how it told me what the student felt, thought and how they examined the frogs.

Current event 4; Mars loops the loop!

Mars loops the loop
By: BBC

Mars is the forth biggest plant circling the sun in the solar System. Mars got its name from a roman god he was the god of war. Mars has a nick name "Red Planet". Mars has similar seasonal cycle as earth. Smooth Borealis in the norther hemisphere covers 40% of the planet.  

Until the first flight by mars in 1965, by Mariner 4, a lot of people wondered if there was water on mars. They looked for water in light and dark patches, mostly in the polar latitudes which are by seas and continents. Out of all the planets Mars is most likely to harbor liquid, and harbor life. People think that mars had a large amount of water on it. 

Mars has two moon, Phobos and Deimos, these two are small and irregular. They might be asteroids, like in 5261 in Eureka. NASA thinks that in the southern polar ice caps have been receding. 

I think that mars is a cool planet and i first heard about it when i say the candy. I never new that mars had two moons and that mars used to have water, because i heard that there was never water and never will be water on mars. Other then mars i would like to learn about other planets as well.

Current event 3= Ancient New Guinea settlers headed for the hills.

By: G. Summerhayes
October 6, 2010

In Papua New Guinea in the mountains archaeologists have found the most remarkable things. They have found stone tools plants remains, and this is in the early 49,000 years ago and people lived 2,000 meter or 1.2 miles above sea level. 50,000 years ago some type of human lived on what we call earth and lived in savannas, rain forests in southeastern Asia's land. 

They have figured out that they have crossed oceans on some kind of ocean craft or boat this was about 10,000 years ago. Archaeologists think early humans spread from Africa to Sahul along the cost and live at low altitudes. Some archaeologists thing are acting nomadic moving from place to place and then after a few years move back to the place were they started. They also found some evidence that they also lived at high altitudes. They say finding modern humans is like trying to find a needle in a haystack. They have used radio carbon to see the dates and they have found a part of a human that is 41,400 years old. They also have found sharp objects that they are guessing is used for spires or knifes to kill animals of to protect them selfs from predators.   

I think that this article is really interesting and that it will  help me with humanities and might help me with science because of the thing they say. But i really enjoyed reading and making an current event on it.
