What makes plastic green?

Green plastic is usually made from corn, sugar beet, and sugar corn. This is what makes plastic green. The problem with packaging that there are so many things in it witch are not needed. A lot of this is waste. At the same time this is mostly recycled or made out of recycled material witch is good. Paper i thick is the most easy to recycle. Metal is hard but could be recycled. to improve packaging i wouldn't put so many materials in the package, if its really necessary i would make the materials out of recycled material.

Food inc reflection

In the movie it showed a lot of affective pictures. What really affected me is how they where treating the animals. After i watched the movie i thought of never eating meat again but every one needs to eat meat because of the the germs that help us grow and survive also the nutrients that the meat has. I really liked the interview of the lady who lost her 2 year old son. He dyed because the hamburgers that he ate had ecolyve in them and because he was so young he was unable to fight it off.

STEM CELLS CREATE MIGHty mice 

Stem cell injections boosted the leg muscles of mice and warded off the typical loss of muscle mass that comes with aging. The discovery could be useful in treating humans with degenerative diseases such as muscular dystrophy, as well as help everyday people prevent at least some of the ravages of time, the researchers said. Scientists removed stem cells from the legs of three-month-old healthy mice and injected them into the legs of mice that had temporary leg muscle injuries, induced by barium chloride injections. The technique repaired the injuries within days and made the treated muscle double in size.

Is it possible to travel to another star?


It would take over 70,000 years. The problem comes with how we can shrink those travel times.
One way to travel to another star is to catch a ride on waves from our own sun. As laid out by solar sail pioneer Gregory Matloff, photons from the sun could push against lightweight, reflective sails to propel a spacecraft. Other theoretical models of sail-based interstellar propulsion systems call
for a magnetic bubble instead of a physical sail. By tethering the bubble to a spacecraft and lining it up with a particle beam, scientists could propel a probe up to considerable speeds.

Human Footprints- Reflection

In the movie that we watched (human footprints) i learned about the food we eat, what we waste, how much food we eat and more. I learned that earth has been round for over 8 billion years. In our history we haven't consumed as much as we do now. We use 3,796 diapers per year till the age 1 to 2 and a half. 1 cow produces 65 hundred gallons of milk per day. We eat 255 eggs per year. We eat 4,376 loaves of bread in our life time. We drink 43,371cans of soda in our life time. We shower 28,433 times in our life time. We use 156 toothbrushes and 389 tubes of tooth paste and 198 bottles of shampoo in our life time.We drink 13,248 cups of beer in our life time. We get 15 computers in our life time. We read 412 books in our life time. 191,000,000 trees are cut down per year. Every person will own 7 cars per life time.1.2 billion cellphones are used right now over the hole world. And every person will take 37,320 pills per life time.


Every thing written hear are all human footprints.  

Survival

Living things have been living on our earth over 600 million years. They can live on our earth because of there adaptation and there camouflage. I learned from the video Survival that a fox can live a long time because some of them can out run a bunny and rabbit, foxes are always living close to humans because humans always have food with them. Other animals like a baby calf has to learn to walk in less then five minutes  after is was born and must learn to run as fast as its mother in one day to protect its self from other animals. Other species like a snaping turtle have a tounge that looks like a worm wich makes fishes hungry and then the turtle just snapes  the fish to ear.

What does Science mean to me

Science is a fascinating subject , there are so many amazing things to learn and discover. In science we can learn about so many things.
EXAMPLE :  Animals, astonomy,biology, chemistry, space, geology and more. Science is the observation, investigation, and explanation of the things that happen around us. 

SCIENCE

Sience is all about having fun and learning new things
