The Chloroplast - YouTube - 0 views
-
In this video Paul Andersen explains how the chloroplast in plants harnesses power from the Sun to form high energy molecules like glucose. The structure of a chloroplast as well as a brief discussion of the light reaction and Calvin cycle are included.
Mitochondria: The Powerhouse of the Cell - YouTube - 0 views
-
In this video Paul Andersen explains how the mitochondria generates energy for the cell through aerobic respiration. He also explains how research into the organelle has shown its importance in eukaryotic evolution.
AP Bio Lab 6 - Molecular Biology - bozemanscience - 0 views
-
Paul Andersen explains the two major portions of the molecular biology lab in AP Biology. He starts by discussing the process of transformation. He explains how you can use the pGLO plasmid to produce glowing E. coli bacteria. He then describes how you can use restriction enzymes and the process of gel electrophoresis to cut and separate DNA.

8' video on origins of life Paul Andersen describes how life could have formed on our planet through natural processes. The progression from monomers, to polymers, to protocells and finally to cells is described. The Miller-Urey experiment is described in detail as well as characteristics of the latest universal ancestor.
The Origin of Life - Scientific Evidence - YouTube - 0 views
-
Paul Andersen discusses scientific evidence of the origin of life on our planet. He begins with a brief discussion of the age of the earth and ends with the future of humanity. He includes geologic, chemical and molecular data.
The Action Potential - YouTube - 0 views
-
In this video Paul Andersen details the action potential in neurons. The resting potential of a neuron (-70mV) is maintained through differences in concentration and permeability of Na, K, and Cl ions. A graded potential is created as neurotransmitters from adjacent cells that are either excitatory or inhibitory. If the neuron reaches the threshold of -55mV an opening of voltage-gated sodium channels triggers an action potential
Student's t-test - YouTube - 0 views
-
In this video Paul Andersen explains how to run the student's t-test on a set of data. He starts by explaining conceptually how a t-value can be used to determine the statistical difference between two samples. He then shows you how to use a t-test to test the null hypothesis. He finally gives you a separate data set that can be used to practice running the test.
Global Climate Change - YouTube - 0 views
-
In this video Paul Andersen explains how the climate on the earth is affected by the amount of solar radiation and the greenhouse affect. The addition of anthropogenic greenhouse gases has led to global warming which is impacting humans on the planet. A discussion of the greenhouse effect and greenhouse gases (including water vapor, carbon dioxide, methane, nitrous oxide, and CFCs) is included. Countries have committed to reduce through both the Kyoto Protocol and the Paris Agreement.
Chi-squared test - YouTube - 0 views
-
Paul Andersen shows you how to calculate the ch-squared value to test your null hypothesis. He explains the importance of the critical value and defines the degrees of freedom. He also leaves you with a problem related to the animal behavior lab. This analysis is required in the AP Biology classroom.
The Neuron - YouTube - 0 views
-
In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also describes how neurons are classified both structurally and functionally.

Mutations - YouTube - 0 views
-
Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes in the recipe can result in changes in the food. He describes the three major point mutations; substitutions, deletions and insertions. He also describes several chromosomal mutations.

Bozeman video 10:26 Paul Andersen explains how life has evolved and continues to evolve today. A brief discussion of artificial, natural and sexual selection is included. The beak of the finch is used to explain how directional selection is achieved.
Speciation and Extinction - YouTube - 0 views
-
Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief discussion of extinctions and mass extinctions is also included.
