Praise Song for the Day

The poem Praise Song for the Day, written by Elizabeth Alexander is a poem written for Barack Obama’s inauguration. The poem describes everyday lives and how they are connected. The meaning of the poem is that everyone has their own unique lives. However, everyone’s lives are connected to their community and so many people have died for them to have their freedom. It is because of this that we should live life with love. Some everyday occurrences and people we tend to see are, “a woman and her son wait for the bus./A farmer considers the changing sky./ A teacher says, Take out your pencils. Begin” (line 13-15). These lines show examples of ordinary people going about their everyday lives and completing the tasks that relate to their communities. The author also uses imagery to describe occurrences where “we cross dirt roads and highways that mark/ the will of someone and then others, who said/I need to see what’s on the other side” (line 19-21). This connects to the idea that the people who came before fought and made sacrifices for the sake of freedom. Lastly the author mentions, “Repairing things in need of repair/ Someone is making music somewhere” (lines 9-10). Repairing things and making music can be seen as acts of care or love and expression, therefore these acts connect to the idea of living with love in our hearts while we do our everyday tasks. In conclusion this poem’s theme describes the lives of everyday people and reminding us to appreciate those from our past.

Friendsheep, A Poem

Friendsheep, A Poem

written in collaboration by: Nour, Jan, Braeden and Jolou

A window cleaning wolf,
Eating a box of mice, with clothes tattered and stained,
gazed through the glass,
Looking at his reflection he came upon an opportunity,
He found an office full of sheep,
That he was very excited to meet and to eat,
He went in disguise, a wolf in sheep’s clothing
He was accepted by the shepherd thanks to his sly deception,
He had succeeded and was ready to feast,
He began to cause mischief with his bag of tools,
However, he also found a companion among the herd,
He shredded office supplies,
He built bonds and became one of the cattle,
His job was a newfound interest,
He found an alternative food, a meal intended for dogs
Because of his new friendsheep,
Suddenly, his supply had run dry
Frantically searching, he tried to find more
He was starving to insanity,
He tried to get away, hold back the attack,
Unfortunately, stuck in an elevator full of temptation, pandemonium broke out,
His effort was futile and a sheep’s head found its way to his mouth,
His boss was unhappy and so his job became crappy,
The wolf was once again a window cleaner,
Until he found another chance to meet someone to eat.

Neuron Communication

Neuron’s communicate through a series of steps which I will guide you through in this blog post!

Firstly, the neuron looks like this:

The process of communication begins with an action potential. The action potential is an electromechanical signal or charge which travels down the axon. This charge is caused by the movements of positive and negative ions. The neuron starts with a resting potential of -70mV. Soon, depolarization occurs and changes the charge to +30mV. Depolarization occurs when a message is sent and stimulates a part of the axon. This causes gateways to open for the positive Na (sodium) ions to enter the axon. Once the sodium enters the axon, the gates close and new doors are opened for the positive K (potassium) ions to exit the axon. This is called repolarization. This causes the charge to return to the regular -70mV charge. However a chain reaction is started and the next segment of the axon starts to depolarize. The action potential then continues to move down the axon.

Now, what happens once the action potential reaches the end of the axon? This is where synapse comes in.

The synapse looks like this:

Once the action potential gets to the end of the neuron, a chemical signal is sent to the next neuron. The signal from the sending neuron’s axon goes to the receiving neuron’s dendrite. The action potential causes the synaptic vesicles to release neurotransmitters into the synaptic gap. The neurotransmitters get through the synaptic gap and then attach to the receptors of the receiving neuron. The neurotransmitters then either, keep the reaction going by stimulating (excitatory) or the stop the reaction by repressing the action potential (inhibitory). This depends on the action of the receptor. Glutamate would cause an excitatory reaction and GABA would cause an inhibitory reaction.
