Lesson Plan
Name
Description
In this lesson, students will analyze an informational
text intended to support reading in the content area. The article
presents exciting new research findings regarding axon
generation in scar tissue formation following spinal cord
injury. Astrocytes were once thought to decrease the growth of

new axon connections, but now these important cells have been
shown to actually stimulate growth and connections in the
neural network. The lesson plan includes a note-taking guide,
text-dependent questions, a writing prompt, answer keys, and a
writing rubric. Numerous options to extend the lesson are also
included.
This a inquiry investigates plasmolysis in plant cells when
exposed to NaCl solution. The ionic solution causes the water

inward. Students will prepare wet mount slides, view, draw,
record time data for plasmolysis, and analyze the data
generated.
This lesson provides a description of the anatomy and
physiology of the nerve cell/neuron. Vocabulary words,
diagrams of the nerve cell, and the steps of nerve conduction are
presented in this lesson. This lesson also includes a hands-on

group activities, diagram worksheets, sentence completion
worksheets, and assessments that require written responses from
the students to describe how nerve cells transmit information
from one cell to another.

Nerve Impulse Transmission
The Nerve Impulse
Description
The transmission of a nerve impulse along a neuron from one
end to the other occurs as a result of electrical changes across
the membrane of the neuron. This tutorial will help students to
visualize and understand the transmission of a nerve impulse.
This tutorial explains that the source of the impulse in a neuron
is a rapid change in the polarity of the cell membrane in a
restricted area. The direction of the electrical gradient is rapidly
reversed and then returns to normal. The change in charge

the Action Potential
stimulates the process to happen in adjacent parts of the cell and
the change in the polarity travels down the neuron.
This tutorial explains how a charge is generated across a
membrane. The function and role of the voltage-gated sodium
ion channel and voltage-gated potassium ion channel are
explained in detail.

Nerve Signaling Game
Neuron
Description
This game is based on several Novel Prizes in Physiology or
Medicine from 1906 until today that have been awarded for
discoveries related to nerve signaling.
Student playing the game will learn...
-How are nerve cells composed?
-How do nerve cells carry the signals that coordinate all the
activities in our body?
-How has the research into neuroscience developed through the
20th century?
In this simulation, you will explore how neurons conduct
electrical impulses by using the action potential. This
phenomenon is generated through the flow of positively charged
ions across the neuronal membrane. Stimulate a neuron and
monitor what happens. You can pause, rewind, and move
forward in time in order to observe the ions as they move across
the neuron membrane.
Other ways to explore:




Describe why ions can or cannot move across neuron
membranes.
Identify leakage and gated channels, and describe the
function of each.
Describe how membrane permeability changes in terms
of different types of channels in a neuron.
Describe the sequence of events that generates an action
potential.

New Role Identified for Scars
at the Site of Injured Spinal
Cord
Description
Recent research funded by the National Institutes of Health
points to scar tissue being beneficial to nerve regrowth in spinal
injury. Previously it was believed scar tissue prevented nerve
regrowth, but this new research shows that astrocyte scars may
actually be required for repair and regrowth following spinal
cord injury.
