A Bright Light

Yes. I skipped a week of writing. Essays, report cards, and the grade 8 graduation trip have taken over my life.  So I am making a concerted effort to get something written today. My adventures of the weekend, albeit limited due to school work, have given me something to write about.

Yesterday afternoon we bought a Boxee. I will explain for those of you who may not know anything about it. A Boxee is a digital box that attaches to your television, and it finds content (movies, series) that is available on the internet and shows it through your television. You can also browse any website on the internet, and it has 182 apps….so far. There are many apps that I still need to explore, and some of them I have never even heard of. Some of the most popular ones are the Khan Academy app, You Tube app, and of course, the TED talk app.

And this leads me to what I want to highlight today. One of my favourite TED talks that I was reminded about was that of Benjamin Zander, a classical musician. He plays the piano onstage, but it is the vibrancy and excitement in his explanations that help to bring the music alive. His passion and enthusiasm for what he does is a bright light at this particular time of the year, when the end of year workload makes it harder to get through each day.

Equal Learning for All….or not.

I had an interesting conversation with a friend a few days ago. She is a teacher,as well, but at a different school. We were talking about our workloads, and I was saying that there never seems to be a break. I mark for hours upon hours at home, and my prep time is always filled at school. I marvel at those who blog and tweet so often, and I wonder where they find the time.

She said it seems that when teachers prove themselves worthy, they seem to get more work put upon them, simply because it is known that they are capable. When administrators need something done or taken care of, they are more likely to head to the stronger teachers, as they are trusted to complete the task well. Yet isn’t it those same teachers who are already working beyond the limits, striving to create the best possible learning environment each and every day? Isn’t it those teachers who need a break?

I began thinking about this, and wondering if we do that to our students, as well. I teach to a high level. I feel that all students are capable, and that they should all be encouraged to reach their maximum potential. Some students may not end up with the same level of absorption as others, but they are all able to enter the process and take out what works for them. I expect all of my students to challenge themselves in some way, but that way does not need to be the same for all students. I do not think that I give extra tasks to particular students, or that I demand less from others. As I write this, though, I can’t help but wonder if my students would feel the same.

Do all students need to be treated equally? No, not in my opinion. But all students need to be treated fairly, and in a way that best supports their individual learning (differentiated instruction, at its best). Equal cannot exist in a world where some can learn math content in 10 minutes and others are still working it through a week later. Equal cannot exist when some can express their thoughts clearly and coherently in written form, while others best share their learning through conversation.  And equal cannot exist when the subject some students excel in is different from that which I teach them.   

Equal does not exist in the classroom, but fairness does. And I tell them that fairness is not necessarily what they think. It is not that each person gets and does the exact same thing as the other. Fairness is about giving each student exactly what they need in order to learn and thrive– no more and no less. And fairness also means that students give back exactly what they are capable of – no more and certainly no less.

Have a wonderful week.

Getting warmer….

In my grade 7 science class, we are currently working on a unit on heat. The students have just finished learning about thermal expansion, and tomorrow they will be handing in an assignment that considers the role of thermal expansion with rising sea levels. I look forward to reading about the various efforts that are undertaken to protect coastlines and river edges from the dangers of the rising waters.

This week’s task will be for the students to assess how to make a home or building more energy efficient. They will explore the various ways that homes and other buildings are designed to maintain comfortable temperatures in various weather conditions. They will consider both the materials used for construction, as well as what goes on within the building. They will be encouraged to investigate the advantages and disadvantages of airtight buildings and how green roofs can be used to help with energy efficiency.

The following is the assignment they will be receiving tomorrow, and the links which will help them to begin their research:

Energy Conservation Inc Word Docx

Energy Conservation Inc PDF

Energy Efficient Homes  from Natural Resources Canada – A good resource – this website discusses energy efficiency in all parts of the house.

US Department of Energy – A similar website as the one mentioned above, this time from the US government.

Energy Star – From the US Environmental Protection Agency, the website behind the Energy Star ratings for your home.

Green 3D Home – Look at the resources under “Go Green” and “Your House”.

Green-Energy-Efficient –Homes – Another website that provides ideas for making your home more energy efficient.

Green Building – This website goes through some of the science behind building green homes.

 City of Toronto Green Roofs – Learn about green roofs and how they are being used in the city of Toronto

HGTV Goes Green – Home and Gardens Television tips and tricks for energy efficient and sustainable homes.

Fun with Applets

This week I am beginning Pythagorean Theorem with my students.  They will have the chance to explore some applets. Here are the ones that I will be using:

IES Applet  This is one of a series of applets on Pythagorean Theorem on this website, but it is my favourite of the group. In this applet squares a and b get broken into pieces, and then all of the pieces from both squares must be rearranged to fit into square c. (Update – link to no longer active)

National Library of Virtual Manipulatives  There are two different puzzles to solve in this applet. In the first puzzle, there is a shape that has an area of c2 and another shape that has an area of a2 + b2. The same pieces are used to fill each of the two shapes, thus showing that the shapes have the same area.  The second puzzle is similar in nature to the first, but the pieces are different and the two shapes are the same.

Nova Applet  This applet allows the user to drag all of square a into square c, and then break apart square b so that the smaller squares fill the empty space in square c.

Davis Associates  This demonstration moves pieces around to show that the area of square c is equal to the area of squares a + b.

After they explore some applets, they will choose their favourite one and attempt to use the concepts to create a hands-on interactive activity. Please feel free to use and modify the following assignment sheet:

Pondering Pythagoras

If you have other Pythagorean Theorem ideas that I could incorporate into my lesson, I would love to hear from you.

Have a  great week.

Cells Galore

I am just beginning my cells unit with my grade 8 students. This year, I want to cover a little of the basics, but then I want to dive into the hearty issues that will require my students to really think and to make judgments about where they stand on some controversial issues.

As my school is an IB world school, we will be exploring this unit with the following question in mind: How do we use biotechnology to meet our needs?

We well begin by covering some of the basics, such as:

  • Cell Theory
  • Plant and Animal Cells (for this I am planning on having the students do an analogy assignment where they compare the parts of the cell to parts of cities, factories, houses, schools, airports…you get the idea)
  • Use and Care of the Microscope
  • Osmosis and Diffusion

The following sites support learning in the topics listed above:

Camilla Senior Cells Page

Science Spot Microscope Links

Teachnology Cells Page

Intel Cell-to-Cell Page

CREATE for Mississippi Microscopes and Cells

Internet4Classrooms Cell Structure and Function

The following are some assignments that I have used in my unit which support the topics above:

Use and Care of the Microscope

Cells Lab

Plant and Animal Cell Scavenger Hunt

Cell Superheroes Assignment

Modelling and Observing Diffusion

Modelling and Observing Osmosis

And then we will move into an exploration of critical thinking issues, such as:

  • Cloning

Learn.Genetics Cloning Page

International Debate Education Association

How Stuff Works:  Cloning

  • Genetically Modified Food

Health Canada

International Debate Education Association

CBC Digital Archives

World Health Organization

  • Stem Cells

Learn.Genetics Stem Cells Page

National Institutes of Health

Science Daily

How Stuff Works

  • The Donation, Selling and Harvesting of Human Organs

International Debate Education Association Page 1

International Debate Education Association Page 2

Santa Clara University:  Markkula Center for Applied Ethics

  • Prenatal Selection of Gender and Genetic Traits

Washington Post

New York Times

Legal Affairs

International Debate Education Association

I have developed a Cell Debate which incorporates the above critical thinking topics.

And finally, for some additional websites to support the study of cells, please check out my cells page.

I am always looking for new ideas to incorporate into my cells unit….would love to hear from you.

Doodling in Math Class

I let my students doodle in class.

Some students just need to move their hands in some way or another, and so instead of them tapping a pencil or ruler on their desk, I tell them to doodle.

Then last week I was introduced to the queen of math doodles, Vi Hart… from one of my students, no less.  If you read math blogs, then you have probably come across her work already. I, however, do not get to read as much as I would like, and so I am thankful that I have an aspiring doodler in one of my classes who is, apparently, more informed than me.  

The first video of hers that I watched was ‘Infinity Elephants’. Yes, you will have to listen to her quips about boring math class, but it is worth it to see her doodle and hear her accompanying explanations. (And despite our best planning and intentions, I am sure that we, the collective math teachers, have managed to bore some of our students at one point or another.)

She has four doodling videos on her blog – Infinity Elephants, Binary Trees, Stars, and Snakes and Graphs.  I have watched all four videos, and enjoyed all of them. One of the extra perks for me were the little snippets from the “The Little Prince“, which you would only notice if you have actually read the book.

When I googled Hart to find out more about her, I came across a video that she had created with references to the original Flatland story. This one, titled “Mӧbius Story – Wind and Mr. Ug”, takes place along a Mӧbius strip – a surface with only one side and one boundary component. Check out her blog and watch her doodle, then come back to see her story along a Mӧbius strip. It is worth a few moments of your time.

Numbers, numbers, everywhere.

It’s a math day.

Every now and then I like to find new sites to help enrich my math program. Here are a few of my old time favourites and some new ones, as well.

Bridgeport Mathematics – This site has resources for pre-algebra, algebra, geometry, and trigonometry. Clicking on each topic brings you to an set of resources for each,  complete with unit overviews (they call them pacing guides), online practice, worksheets, and additional links. There are also math cartoons and math magic games, as well as a direct link to the National Library of Virtual Manipulatives.

mathcentre  – Another good resource site for math videos, worksheet booklets, games, and so much more.

Yummy Math – This sites brings in real world connections to various topics across the math curriculum. (I also like the mathalicious site for real world connections in math, but they are currently under construction – should be up and running soon.)

Mathwire – A great site for math enrichment activities.

nrich – This site provides Rich tasks for the math program. It is based in the UK, so look to the key stage/age equivalencies on the help page.

The last site I will highlight today is from the Utah Education Network, which provides math interactive activities across the curriculum.

 And if you find yourself with a spare moment or two (or nine), you can always enlighten yourself with a bit of global population statistics from the educated mind of Hans Rosling.

World Health Day 2011

April 7th is World Health Day. Every year the World Health Organization creates a World Health Day with a different theme. This year’s theme is “antimicrobial resistance and its global spread”.  What does this mean, exactly? It refers to a resistance to the various antibiotics medications that we use to fight infectious illnesses and diseases. At some point they become ineffective in our bodies, thus no longer achieving the goal for which they were created. This problem is becoming more widespread. The World Health Organization is using World Health Day 2011 to bring this issue to the forefront in the eyes of governments and stakeholders so that they can begin to combat this problem.

Who are the stakeholders? The people within the World Health Organization might have their own opinions, but I think that the stakeholders would be every living person in this world. The entire human population stands to gain, or lose, from the effectiveness, or lack thereof, of the various medications that we use to fight infection and disease.

It may be too late to plan a whole unit around this topic in time for World Health Day this year, but you can certainly begin the conversation by introducing some thought provoking activities. Here are some links to get you started in your planning:

World Health Organization – This is a direct link to the World Health Day page on their website. Go here for information about World Health Day for this year, and for past years. Here is their document which provides information about antimicrobial resistance:  World Health Day 2011

Antimicrobial Resistance from Public Health Agency of Canada

Antibiotic Awareness

Evolution and Antibiotic Resistance from PBS

Similarities Between Spread of an Infectious Disease and Population Growth

Unit Plan on the Evolution of Antibiotic Resistance

Don’t think better, think different.

At the beginning of each school year, parents pour into my science classroom on curriculum night, eager to hear what their child will be learning in the coming months. About three years ago my message to parents changed. I have begun telling them that I still teach content in my science class, but it is no longer the focus of our curriculum. Content is now everywhere, and in today’s world it is not something that a student must rely on the teacher to provide. Skills, however, still need to be learned. And so I tell parents that my job is to teach the students how to find the content, how to use the content, and when to believe the content.

This does not mean that I do not teach them scientific concepts. Biology, chemistry, and physics are still active parts of my classroom curriculum. However, my focus is on them learning how to carry out a lab and connect their results to the world around them. I teach them how to brainstorm, design, and build various items that will achieve a meaningful purpose. I let them explore various opinions on topics and then explain where they stand on these issues.  I make them think about their every day actions with regard to the sustainability of our world, and I require them to consider the repercussions of their choices. I let them create with technology so that they are prepared to engage with a world that is changing by the moment. And I learn that new technology myself, because I believe that if I don’t attempt to keep up with my students, then they will leave me far behind.

And so for today’s post I thank Thomas Whitby for directing me to this TEDxNYED video of Will Richardson. Hearing his thoughts have validated my own. Despite our own personal ideas of what education should be, sometimes a little validation goes a long way.

Below is Will Richardson’s TEDxNYED speech. Check out his blog at weblogg-ed.

Let the Lights Go Out.

There are several times a year when we are specifically asked to think of the world that we live in and the effect of our actions on our world. Earth Hour is one of those times.

Earth Hour is from 8:30 to 9:30 pm on March 26th. It began in Australia in 2007, when over 2 million individuals and businesses turned off their lights for one hour to “take a stand against climate change”.  Over the next few years it captured global attention, and last year over 126 countries took part.

As it occurs over the weekend, some schools have incorporated it into their curriculum by designating time on the Friday beforehand to turn off as much electricity as possible. They are also teaching lessons on environmental responsibility and sustainability leading up to the event. You could spend hours upon hours searching the web for ideas, and not even make a dent in what is available. Here are but a few resources to help you incorporate Earth Hour into your curriculum:

Earth Hour Main Page

Earth Hour Primary Education Pack 2011 from the Earth Hour website

Earth Hour Secondary Education Pack 2011 from the Earth Hour website

Earth Hour Canada Page

Earth Hour 2011 Official Video

Vote Earth Sand Painting (Even if you don’t use it in the class, watch it – pretty neat.)

The Story of Stuff This is a twenty minute video that highlights the waste in our society.  Go to the original vide0 “The Story of Stuff”, or to the videos on electronics or bottled water.  They are suitable for older grades.

Environmental Jeopardy – Various versions of this game are available, each with a different focus. This is actually a printable game – use it in Jeopardy style or simply as a trivia challenge. It is suitable for older students.

United States Environmental Protection Agency Lesson Plans

Check out the Smart Exchange for Smartboard Notebook Activities with an environmental theme.

It is important to have our students take part in global actions for preserving our environment, and thus I feel that teaching them about Earth Hour is the right way to go. However, we need to ensure that our lessons go beyond them thinking that environmental sustainability can be solved in one hour. For it is only through our day-to-day choices and related actions that any true change will take place.
