OBJECTIVES AND FINAL GOALS
Objectives: What is the topic of the activity? What do I want students to learn? What do I want them to take away from this particular activity? At the end of this activity the students will be able to know what a motor neuron is like, they will be able to make their video and edit it and expose their defense of their opinions with scientific vocabulary.   ------------------------------------------------------------------------------------------------------------------------ Goals:   By the end of this learning activity, students will be able to will be able to know what a motor neuron is like, they will be able to make their video and edit it and expose their defense of their opinions with scientific vocabulary.
WORK PROCESS
BUILD: a MOTOR NUERON Step 1: Roll modeling clay into a ball and flatten it into a circle. Place the puck on the table.   This represents the Soma or Cell Body: the circular portion of the neuron. With the nucleus, it takes care of the function of the cell.   Step 2: Make a much smaller ball of clay and flatten it into a disk. Place this disk on top of the first disk that represents the nucleus.   The nucleus is the organelle found within the cell body that contains the plane of the neuron or DNA.   Step 3: Time to get creative! Here you can unfold logs and create small tree-shaped branches. Then join them around the cell body to create the dendrites. Neurons come in many shapes and sizes. Make as many dendrites as you want!   Dendrites receive messages from other neurons, the information that reaches the cell body to activate the cell.   Step 4: Roll out a long stem of modeling clay to adhere to the cell body between the dendrites to represent the axon.   The axon is a long fiber in the cell body that transmits action potentials from the nucleus to the terminal of the axon.   Step 5: Create several small rolls of modeling clay and attach them as branches at the end of your axon to make the axon terminals.   The Axon Terminal is the location where action potentials are transformed into neurotransmitters to be released to the next neuron.   Step 6: Make several small balls and flatten them into ovals or rectangles. Use them to wrap around your axon to represent the myelin sheath.   The myelin sheath is like insulation that surrounds the axon, helping to transmit action potentials quickly to the axon terminal.   Step 7: Create several plasticine balls and place some on the tips of the axon terminal and others inside the branches. These are your neurotransmitters.   Neurotransmitters are chemical messengers that move the message from the terminal axon of one neuron to the dendrites of the next neuron.             Video at the same time one of the students is recording all the steps of the construction. We will go to the computer room so that each group can edit their video       Putting in common   For groups of 4 people, a spokesperson is chosen, who will be the person who defends in front of the whole class, the built motor Nujeroan and the video At the end when all the groups have exhibited, the two best neurons and the two best videos will be voted on. With all the neurons, an exhibition will be made at the entrance of the Institute, so that everyone can see the work and with the videos all will be uploaded to the center's website, to the students' blogs and each student if they want to their social networks,
APPLICATION OF NEUROSCIENCE CONCEPTS
Based on what we know about attention and the way our brain reacts to external stimuli, I have divided the activity into 5 shorter sections of a maximum duration of 10 minutes each for the construction of motor neurones. In the video classroom I carry out an initial motivational session of 5 minutes and then I divide the work periods into 3 groups of 15 minutes. For group discussion, I divide the time into periods of a maximum of 5 minutes for each group. This should ensure that students can hold their attention and are motivated to respond with curiosity at the beginning of each section.
