Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: Brain Development and Brain Damage.
Level#1
The human brain begins developing as early as two weeks into a woman's pregnancy. It begins as a tube made of nerve cells. By about the fifth week of pregnancy, this tube of cells has become bigger, rounder, and more complex. It eventually turns into a small brain. As the fetus, or unborn baby, develops, the brain continues to grow and develop. The brain is considered fully formed by about the fourth month of pregnancy. Any harmful substances that the mother takes into her body can damage the developing brain of the fetus.
1. When does a human brain begin developing?
2. What does the brain begin as and what happens by the fifth week of pregnancy?
3. What does the tube of nerve cells eventually become?
Level#2
The human brain begins developing as early as two weeks into a woman's pregnancy. It begins as a tube made of nerve cells. By about the fifth week of pregnancy, this tube of cells has become bigger, rounder, and more complex. It eventually turns into a small brain. As the fetus, or unborn baby, develops, the brain continues to grow and develop. The brain is considered fully formed by about the fourth month of pregnancy. Any harmful substances that the mother takes into her body can damage the developing brain of the fetus. Because the brain controls so many functions, damage to the brain can cause serious health problems. Brain damage can impair many human functions, such as motor skills, muscle control, speech, and powers of reasoning, learning, and thinking.
1. When does the human brain begin to develop and what does it begin as?
2. What happens to the tube of cells by the fifth week of pregnancy and then what does it eventually become?
3. What happens to the fetus, or unborn baby, as it develops, and when is the brian considered to be fully formed?

Brain damage can impair many human functions, such as motor skills, muscle control, speech, and powers of reasoning, learning, and thinking. When young people suffer brain damage, it is usually due to accidents. Brain tumors and infectious diseases can also be very damaging or even deadly. Not all tumors are cancerous. Tumors that are cancerous can sometimes be treated with surgery and drugs. Meningitis and chorea are two infectious diseases that attack the brain.
1. Explain when the human brain begins to develop and what it begins as.
2. Explain what happens to the tube of cells as it develops and what it eventually turns into.
3. Explain what happens as the fetus develops and when the brain is considered to be fully formed.
