What scientists know for certain about the teenage brain?	How scientists interpret these facts?	What scientists still want to learn about the teenage brain?
Rates of death by injury between ages 15 to 19 are about six times that of the rate between ages 10 and 14. Rates of death by injury between ages 15 to 19 are about six times that of the rate between ages 10 and 14. The volume of gray matter which is where thought and memory take place peaks in early adolescence.	There are a lot of factors influencing the development of the teen brain: experience, biological changes, environment Controlling impulses and planning are among the last parts of the teen brain to mature. Scientists believe that the loss of synapses as a child matures is part of the process by which the brain becomes more efficient. Although genes play a role in the decline in synapses, animal research has shown that experience also shapes the decline. Synapses "exercised" by experience survive and are strengthened, while others are pruned away.	The significance of the adolescence period on lifelong mental health. Scientists are working to determine to what extent the changes in gray matter on brain scans during the teen years reflect growth and pruning of synapses.

Reflection:
A time that I took a risk and won is when I got pregnant and decided to have my baby. At first I didn't think it having my son was a risks but if you think about it anyone having a baby is a risk. There are so many risks that could happen when being pregnant and having a baby period, The rate of severe complications during and after delivery have also doubled in the last decade, according to a 2012 federal study. Near-misses, where a woman nearly dies, increased by 27 percent. I'm grateful that during my pregnancy and after my labor I was fine and my son was a health baby boy.

A time when I had took a risk and it turned out to be a bad risk was when I was I was younger and I went I bike riding with my cousin on dirt mountain and I ended up getting stuck on the top and almost falling to my death.  

Quick write:
I haven't had an experience where I had to re-learn how to do something, i could only imagine how difficult it would be if for example i was to break my right hand and have to write with my left hand.  

Quick write:How much of our brain do we actually use ?

"It turns out though, that we use virtually every part of the brain, and that [most of] the brain is active almost all the time," Gordon adds. "Let's put it this way: the brain represents three percent of the body's weight and uses 20 percent of the body's energy.
