Last year, 15 teams went out on there first quests, a 142 mile car race across a desert. But the thing was that the teams could not be in the car and they could not use remotes, the car had to drive itself. The cars had to be able to drive over any type of terrain and had to be able to go around obstacles. All the cars crash, stalled or burned, so the student had to re- think there strategies. Only five out of 23 finalist went 130 miles. The winners car did the course i 6 and his car maximum speed is 30 kilometers per hour. 

The cars are being examined by the army and some others but the army really wants theses cars for battle so that the dont risk as many solders as they did in all the other armies. The army tecno people are trying to add James bong features into the cars. The cars would also be used to transport hurt solders from place to place and to bring goods and medications to the bases, and they would do this if they used the cars. 

Experts were inspecting the car that won and he found 5 laser beam sensors on top of the car and computer software that would help make the car avoid obstacles. Experts also predict that soon maybe people might be using these cars and trucks to go to work and to use in the general life and it would make roads safer and easier in some way.     

I think that is would be awesome if we could go to school and other places with out a driver and i bet our parents would like to so they could relax will we go on long road trips, but one thing i am not sure of it what about our drivers what would happen to there jobs and how would they get money but other then that it is so cool and i think it could really help the world in war and in general.  

Reflection on glogster presentation

This reflection is going to be about my glogster page which i did a few weeks ago for a book that i read, the book is calles "Ravens Gate" the book is a non fiction book but it really makes your brain work in the sense it makes you pounder and its full of mysteries. Now lets go into the book.

The reason we made a glogster for our book is because we wanted to share and show all our interests in book and what they have to offer. My book is Ravens Gate it is a great book if you like mysteries and wild features like power, magic and other crazy fiction things. This book brought me rupture because it was interesting and once you start you can never stop reading it. The book was about a boy and his friend that went into a ware house that had a every game in the world and all of these games were not out in the stores yet so they wanted to get them before anyone else did. When they were in there a police man came and then the boys were dumbfounded and they went to jail for 2 days so that the get a punishment for what the did. The way i did the glogster page was revolved around death and blood most and that was the theme for the page, but the writing was pretty peace full and it was with blood or anything. I thought that the book and the glogster were great for me and i really enjoyed doing it and the best part was that i could show it to all my class mates, so they could understand and know what i am reading and learning in the book. But the only thing i didn't really like in the book was there were to many deaths, killing and blood all of those i dont like.

So from my reflection you should get a good sense of what my book is about and my feeling about the book and the whole project its self, hope you like the book if you ever read it after you read my reflection.

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.

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.
