This 89-slide package of teaching PowerPoint presentations covers all of 3.E (Communication) in the AP Biology (2015) curriculum. Each slide includes the 'Essential Knowledge' being covered as well as key terms that students should make note of (editable).
Unit 3.E includes four sections:
• 3.E.1 - Information
• 3.E.2 - Nervous System
The presentations themselves contains minimal information as they are intended to be used with teacher guidance. There are 'Video' slides throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the AP Bio Essential Knowledge objectives. The remaining class time is spent reinforcing the knowledge or working on activities geared toward the 'Learning Objectives'.
I have included PDF version of the PowerPoints for handout purposes.
**These presentations are based on the AP Biology Course Guide and does not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

3.E - Communication
Transmission of information results in changes within and between biological systems.
3.E.1 - Information
Individuals can act on information and communicate it to others
a. Organisms exchange information with each other in response to internal changes and external cues, which can change behavior.
- Fight or flight response
- Predator warnings
- Protection of young
- Plant-plant interactions due to herbivory
- Avoidance responses
b. Communication occurs through various mechanisms.
- 1. Living systems have a variety of signal behaviors or cues that produce changes in the behavior
of other organisms and can result in differential reproductive success.
- 2. Animals use visual, audible, tactile, electrical and chemical signals to indicate dominance, find
food, establish territory and ensure reproductive success.
c. Responses to information and communication of information are vital to natural selection and evolution.
- 1. Natural selection favors innate and learned behaviors that increase survival and reproductive fitness.
- 2. Cooperative behavior tends to increase the fitness of the individual and the survival of the population.
3.E.2 - Nervous System
Animals have nervous systems that detect external and internal signals, transmit and integrate information, and produce responses.
a. The neuron is the basic structure of the nervous system that reflects function.
- 1. A typical neuron has a cell body, axon and dendrites. Many axons have a myelin sheath that acts as
an electrical insulator.
- 2. The structure of the neuron allows for the detection, generation, transmission and integration of
- 3. Schwann cells, which form the myelin sheath, are separated by gaps of unsheathed axon over which the
impulse travels as the signal propagates along the neuron.
b. Action potentials propagate impulses along neurons.
- 1. Membranes of neurons are polarized by the establishment of electrical potentials across the membranes.
- 2. In response to a stimulus, Na+ and K+ gated channels sequentially open and cause the membrane to
become locally depolarized.
- 3. Pumps, powered by ATP, work to maintain membrane potential.
c. Transmission of information between neurons occurs across synapses.
- 1. In most animals, transmission across synapses involves chemical messengers called neurotransmitters.
- 2. Transmission of information along neurons and synapses results in a response.
- 3. The response can be stimulatory or inhibitory.
d. Different regions of the vertebrate brain have different functions.
