begin the lab

Lab

• As you complete the dissection, imagine you are Galen in the 2nd century – you see the anatomy, but can you imagine physiologically what these parts do?

• What clues could you use to figure out what the different parts of the brain do?

Comparing Sheep and Human Brain

Key Differences• Size – Human brain is larger– 1400 grams vs. 140 grams

• Shape – elongated vs. circular• Humans – larger prefrontal

cortex– Complex cognitive behavior,

personality, decision making, executive functioning

• Humans – more ridges and contours of cerebrum– Increased surface, increased

efficiency, more neurons

• Sheep – larger olfactory bulb– Responsible for smell

• Sheep – larger pineal gland– Responsible for reproduction and

circadian rhythms

• Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving

• Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli

• Occipital Lobe- associated with visual processing

• Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech

Beginning the Research Process

Organizing Your Sources

• Go to Google Drive• Open your shared History folder• Create a new folder – “Research Project”• Create a new document – “Last Name –

Sources”• Every source you take notes on, put a complete

citation in MLA format in this document.– Don’t number your sources, use letters– First source is A, then B, and so onFOR MORE INFO ON HOW TO CITE IN MLA FORMAT, SEE THE

SUBFOLDER IN THE RESEARCH PAPER RESOURCES FOLDER ON MOODLE

What is a Research Note Card?

• What is it?• Why do we use it?

Introducing Research Note Cards

• Go to Google Drive• Open your shared History folder• Open your Research Project folder• Create a new document – “Last Name – RNCs”• Go to Moodle, Topic 10, Research Paper

Resources – open the link to the Research Note Cards template – Cut and paste a bunch of RNCs in your document

“Last Name – RNCs”

Exit Ticket

• On a piece of paper write down the following:– The name of your person for your research project– 2 facts you learned about them over the weekend– If you don’t know anything about them, write

down what you will do tonight to learn something about them
