A Look at Families of Elements

On the 28th of November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for the four new elements that had been previously discovered during the past few preceding years: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively for element 113, 115, 117, and 118. The periodic table of element was first organized into its modern form by the Russian chemist Dimitri Mendeleev in 1863.

Mendeleev noticed that 56 known elements of his day displayed more than the simple pattern of increasing in atomic mass. He realized that groups of elements had similar physical and chemical properties that they shared with one another, despite having different atomic masses. He used his newly formed period table to correctly predict the properties of eight elements that had not yet been discovered!

Using their knowledge of the periodic table and understanding that elements in the same groups/families on the periodic table share similar physical and chemical properties, the grade 9 science class put their scientific investigation skills to observe four sets of chemical reactions to determine which solutions belonged to the same family on the periodic table.

Students reacted silver nitrate separately with potassium chloride, potassium iodide, potassium bromide and potassium sulfide. After reacting the solutions, student recorded their observations and applied their knowledge and understanding of the periodic table to figure out which of the potassium solutions (if any) were part of the same group/family.

2017 Valentine’s Dance!

The YMCA Academy Leadership and Peer Support class hosted a Valentine’s Day dance on February 14th, 2017. The tickets were sold at the price of $5 during lunch from Thursday, Friday, Monday, Tuesday, and also at the dance (if you were last minute). Our Leadership and Peer Support class worked to plan and setup the dance for about a week and half. Students requested many songs to be played at the dance and our very own DJ B tried his best to get each student’s request to be played in one long list.

At the Valentine’s Day dance students had fun by dancing, hanging out with friends, eating nice treats made by our very own Cooking Club runned by Katie Clay. All the money that was raised by the Leadership and Peer Support class will be going to the YMCA Youth Exchange Program. The amount raised was a whopping $172.95. All in all the dance was a successful night and everyone in the dance seemed to enjoy their stay. For people that think this might be the last dance. Think not. There will be more dances to be hosted in the near future!

Thank you to Central YMCA for letting us book the auditorium!

Biochemical Compounds in Food Samples

There are four broad classes of macromolecules that can be found in living systems. Each type of macromolecule has a characteristic structure and function in living organisms. You can use your knowledge of the basic structure of each macromolecule to perform tests in the lab that detect the presence or absence of key functional groups or overall characteristics in various substances through the use of indicators.

Students were given a scenario in which they had to play the role of scientists at a Canadian Food and Drug Administration Center for Nutrient Analysis where they test various food items for protein, lipid and carbohydrate content. In the face of an impending zombie epidemic, they must use their knowledge and understanding of biochemical compounds to determine which food substances could be used to quell the zombie epidemic. To do this they must analyse a variety of foods to determine which has the highest levels of complex carbohydrates and proteins which have been found to kill the zombie’s brain cells.

The Cookbooks are Ready for Sale!

The YMCA Academy cookbooks have been printed, packaged and are ready for sale! The idea of the cookbook came from the Cooking Club which meets each week to create delicious and nutritious foods. The club has gathered their favourite recipes and compiled them with recipes submitted by students, staff and friends of the Academy. All together there are 115 recipes spiral-bound together with a custom cover of Cooking Club photos.

These cookbooks make wonderful holiday gifts and are a great way to support the Academy. The books cost $20 for one or two for $30 and all of the proceeds will go to programs that benefit our students, such as Cooking club and the YMCA Youth Exchange. If you would like to place an order, please e-mail Katie Clay at kclay@ymcaacademy.org.

Thank you to everyone who has contributed to this project and to those who have purchased cookbooks. Your ongoing support of the Academy is so appreciated!

Hot Docs Documentary: Chasing Asylum

YMCA Academy students attend Hot Docs Ted Rogers Cinema to watch Australian documentary Chasing Asylum

As teachers, many of us believe that documentary films are often excellent resources for exploring, and exposing, the realities of our world, as well as for looking at the different ways this reality can be shaped. And so, more than 30 Academy students headed out on a chilly morning this past Thursday to attend a special screening at the Hot Docs Ted Rogers Cinema of the Australian documentary Chasing Asylum, which exposes Australia’s treatment of asylum seekers, including their indefinite detention in bleak offshore camps.

The film, from Eva Orner, had just won Best Feature Length Documentary at the AACTA Awards (a.k.a. “the Australian Oscars”) only a few hours earlier, and is notable for combining secretly filmed footage from inside the detention centres with more traditional interviews and clips. Viewing it wasn’t exactly an easy or pleasant experience, but was a powerful and revealing one. I believe that many of us left the cinema with great appreciation for the efforts of all those involved in the documentary, some of whom could, under current Australian law, face up to two years in prison for exposing injustice and abuse from a government that claims to respect the rule of law, freedom of speech, and international human rights agreements including the Universal Declaration of Human Rights, the 1951 Refugee Convention, and the Convention on the Rights of the Child.

Around the world, December 10 marks Human Rights Day, and every year around this date, the Docs for Schools program features a rights-themed film that includes a speaker from a collaborating organization as well as a Q & A with the filmmaker. This year, the discussion had to be held via Skype, but Ms. Orner had risen at 3am (in Australia) in order to answer the thoughtful and perceptive questions posed by some of the few hundred youth in attendance, including from a keen young Academy attendee.

This is the second year in a row that a group of Academy students has attended the December event, and students have enjoyed a number of other Docs for School screenings. Coming back from this particular film, students here were full of probing questions, deep concerns, and impassioned pleas for action. On the other hand, most of the seats were empty when Chasing Asylum screened at the Australian Parliament, with only one MP and one senator in the small crowd that turned out despite thousands of invitations being sent out. Most other screenings of the film, including ours, have been fully booked. Hopefully, this is a sign that the next generation of decision-makers will be more willing to at least inform themselves of what is happening to some of the most desperate and vulnerable people of our world.
