A Web Quest for 7 th -12 th Grade Students By Shannon Hernandez & Mike Shaw of CSNE

Click on the link & read “The Central Nervous System”: Eric Chudler Link Answer the following questions in your notebook: 1.How many parts make-up the central nervous system? 2.How many nerve cells are in the brain? 3.Are there any other special cells in the brain? 4.List them.

Click on the link: “Structures & Areas of the Human Brain”“Structures & Areas of the Human Brain” In your notebook: 1.Make a drawing of the brain with the spinal cord. 2.Label all the parts. 3.Write a description to list what each part does. 4.Show your partner & have them sign-off you did this.

Click on the link & observe the images of neuron diagrams by Cajal. Cajal Neuron Images Click on the link & observe other images of neurons: Neuron images Answer the following questions in your notebook: 1.Do all neurons look the same? 2.What are some differences mentioned in Cajal’s images?

Click on the link & read about neurons. “Neuroscience for Kids”“Neuroscience for Kids” Answer the following questions in your notebook: 1.What is a neuron? 2.What does it do? 3.How many neurons are in the human brain?

Click on the link: “Neuron Diagram”“Neuron Diagram” In your notebook: 1.Draw a typical neuron. 2.Label the parts. 3.Write a description to list what each part does. Image Source: J Sans HHMI, Harvard

Click on the link & play the game: Screen shot with snipping tool your score & to your table partner for credit.

Click on the link & read about synapses: "Neurons Communicate Via the...""Neurons Communicate Via the..." Click on the link & watch the video: “Molecular mechanism of Synaptic Function” “Molecular mechanism of Synaptic Function” Answer the following question in your notebook: 1.What type of signal is transmitted in the synapse? 2.Do neurons actually touch other neurons?

Click on the link & watch the video: "Crossing The Divide": "Crossing The Divide" Click on the link & read: “Types of Neurotransmitters”“Types of Neurotransmitters” In your notebook: 1.Write a description for how neurotransmitters work as though you were explaining it to a 6 th grader. 2.Explain the importance of “Dopamine.” 3.Write an open ended question about neurotransmitters?

Use the next slides to check your partner’s journal drawings of the brain, neurons & synapses.  Did they label the parts?  Did they list the functions of the brain?

Functions of the Brain Transparency G

Sending the Message across the Synapse receive messages carried by the neurotransmitter 4 Receptors 3 Neurotransmitters carry messages from one neuron across the synapse to another neuron. Dopamine is the most common neurotransmitter in humans. 2 Synapse gap between neurons where messages travel across the synapse to another neuron 1 Axon Terminals places where messages are changed from electrical to chemical and are released into the synapse
