Neurons in all areas communicate via action potentials and neurotransmitters. When neurons in
an area fire action potentials, you experience some type of perception. We do not understand

The speed of light theory tells us that for objects in motion, time passes slower. There is
no one time, there are times, depends on state of motion
a. This means for 2 different observers, an event cant be considered simultaneous.

1) How do we know that the universe is expanding? What is the big bang?
a. We know the universe is expanding because scientists have measured points
on the universe and over time, those points have become further out into
space. The b

How do FMRIs work?
a. How do they work/What do we wish to measure/what do we wish to know?
- Measure increases in brain activity (action potentials). We want to know
how strong different parts of the brain are functioning.
Scientific Habits of Mind
A partial list of the habits covered in Frontiers of Science, Fall 2011
Chapter 1: Sense of scale
1. A sense of scale. Particularly spatial scales (nucleus, atom, neuron).
2. Units and unit conversions, scientific notation.
Week 1: Faces and the Brain
1. What does your brain look like (anatomy), and how does it work (physiology)? 4 lobes: Frontal: reasoning & motor skills; Parietal: touch; Occipital: primary visual cortex
(sight); Temporal: interpreting sounds (
