Part I: BRAIN ANATOMY - Exterior. Go to and allow the multimedia to load. When ready, click on “Brain Anatomy” and go through each section. Summarize the functions of each and label it on the diagram. Don’t copy word-for-word from the website; just briefly list the purpose of each section.

Label each part below:

Cerebellum:

Frontal Lobe:

Occipital Lobe:

Part III: BRAIN IMAGING. Go to to learn about two popular (and complex) brain imaging techniques, the PET scan and the MRI.

A PET scan stands for “Positron Emission Tomography”. On the website, read the two sections labeled “Choosing a Compound” and “How PET Scan Machines Work”, and then summarize the usage of PET scans in analyzing brain activity by answering the following questions. Try to make it as simple as possible and put it into your own words.

How do PET scans work? What’s involved in the process?

What do the various colors on a PET scan indicate?

Red = _________________ Orange/Yellow = _________________ Green = _________________

Blue = _________________ Grey = _________________

Next, read the sections regarding the MRI machine (Magnetic Resonance Imaging)

labeled “How MRI Measures Brain Activity” and “Radio Waves: More Than Music”.

How does an MRI differ from a PET scan? How does the MRI work?

Part IV: THE CHILD’S DEVELOPING BRAIN. Go to to learn about how the brain develops throughout childhood into adulthood.

4 years old - Which function of the brain has already mostly finished developing by age 4?

6 years old - Why do children at this age often throw tantrums and have trouble juggling information?

9 years old - What fine motor skills are children beginning to develop at this age?

13 years old - Why is judging risk or making long-term plans difficult for children at this age?

15 years old - How does the child’s brain become more specialized and efficient as it ages?

17 years old – The maturation of what area allows teenagers to plan and develop self-control?

21 years old – What skills or specializations are the last for the brain to develop into adulthood?
