What will you find here? On MrCollinson.ca you will find full science units for grades 1, 2, 3 and 4, including printable lesson plans, worksheets, quizzes, tests and other assessments. On top of that, each activity also has an answer key. The resources will cover the Ontario Science Curriculum for each of these grades. There are also links to some of my grade 7 and 8 materials, however I am currently teaching these grades and cannot put everything up.

I have put up one of my grade 8 projects on Teachers Pay Teachers, to see how it goes. Feel free to check it out.

You will see a series of advertisements on each page. These are ads I have put through Google Adsense, and their presence allows me to keep the resources free. Please don't hesitate to have a look through the ads, as they support the fees necessary to run this site.

Well, let's get to it. The link below will take you to the resources, and explain everything in more detail

Science Resources

Please help me out by spreading word of MrCollinson.ca. Also. don't hesitate to submit the site to any teacher resource groups you use. Basically, I would love to get advertising up so that I can continue to run the site.

Lastly, please do not hesitate to contact me if you have any questions.

Know any French teachers? Check out this awesome new site, tons of videos for the French classroom:

Have you ever been surfing? Many people love swimming in the ocean, but there's nothing quite like the rush of jumping up on a as a large ocean propels you toward the shore.

You probably already know that sound travels through the air in waves. Unlike the water waves you can surf on, however, sound waves are invisible. When they carry inspirational words or music, though, you certainly can ride them to a whole new place in your mind.

Sound waves move through the air around you most of the time. While the air might seem rather empty, it's actually filled with lots of air molecules. When vibrating objects, such as your vocal cords or the strings of a piano, make sounds, they do so by causing the air molecules to move in waves that your ears receive and as sounds.

Sound needs air molecules to travel. That's why no one would be able to hear you if you screamed in outer space. The of air - called a vacuum - in outer space prevents sound from traveling.

You've probably seen a lot of science-fiction movies that feature spectacular battles in outer space. Lasers flash across the sky and spaceships explode in loud bursts of sound and light. In reality, you'd be able to see, but not hear, those explosions. Moviemakers add sound to make the experience of watching the movie better.

Here on Earth, though, there are plenty of air molecules to help sound travel. In fact, sound travels really fast through the air. How fast? Sound moves at a quick 1,125 feet per second in dry air at 68º F at sea level. That's about 767 miles per hour or approximately a mile in five seconds!

Vibrations that make sound waves create compression or longitudinal waves. These waves travel in the same that the sound is moving. This makes sound waves different from water waves, which move up and down and are called transverse waves.

Like all waves, sound waves have the characteristics of wavelength , , and . The wavelength of a water would be the distance between crests. Since sound waves are compression waves, their wavelength is the distance between maximum compressions. is a measure of the rate at which sound waves pass a given point. Their measures how compressed the waves are compared to the air around them.

In addition to hearing sound waves, you can also sometimes feel them. If you stand in front of a loudspeaker at a rock concert, you will definitely be able to feel the pulsing sensation of the sound waves as they hit your body. Even though you can't see them - or ride them on a surfboard like a water - sound waves can definitely transport you to other worlds as you listen to beautiful music or powerful speeches!
