Tonight is the first full moon in July! apparently this moon is used to mark lots of special occasions such as bucks beginning to grow their antlers.
In some parts of the world it will also be a partial lunar eclipse tonight, but that won't be visible in North America. Click the link below to watch a short video to learn more!
On Friday we had a former V-O Parent visit to give a presentation on sound. He talked all about sound waves and we even dissected a speaker to see how it works!
We also talked about electromagnets and how the strength of electricity through the electromagnet's wire forces two magnets to repel, and when doing so push air with a paper disk to create sound waves fast enough for our ears to hear.
So you can imagine how excited I was to come home and discover this video that shows sound waves from FIRE using something called a Rubens' Tube.
Check it out!
Another fun video by the Slow Mo Guys slows down a video to show a speaker jiggling the air. They poor a bunch of paint on a speaker, then turn on some sound. The paint begins to bounce as the speaker begins to jiggle and spread the sound waves!
Today in class we did an experiment to see what types of materials reflected, refracted, absorbed, or transmitted light. Watch this Study Jam for a quick review.
Below is a pretty cool video showing how water can refracts light.
A few of you have been interested in learning more about color blindess as we studied light and color today in science. This article may be of interest!
Awesome Animation Shows You What Colorblind People See June 30, 2015 | by Danielle Andrew
Colour blindness, or colour vision deficiency, affects approximately 1 in 12 males, and 1 in 100 females. There are various causes for the condition. For the majority of sufferers, the condition is genetic. However, illnesses such as diabetes and multiple sclerosis can cause degeneration of sight and cause vision deficiencies.
So have you ever wondered what the world looks like to the colour blind?
What you should see is the colours of the pencils fade out. If you don't see any change over a period of 5-10 seconds you might want to pop down to your local optometrist - especially as 40% of pupils currently leaving secondary school are unaware they have vision or colour deficiencies.
There Are 3 Forms Of Colour Blindness.
Protanopia, in which seeing and distinguishing between colours within the green-yellow-red section of the spectrum is impossible,
Dueteranopia which means sufferers struggle to see green-yellow-red,
and a rare type of colour blindness, tritanopia, which means sufferers can't see blue-yellow.
Website Etre have created an awesome simulator which allows you to upload any image of your own, choose which condition you want to simulate, and create an image as the sufferer would see it.

Want to see some simple machines in action?
Do you like good music?
Click HEREto see a video of a Rube Goldberg Machines featured in a Music Video. I added some comments to the video to highlight some of the simple machines. Can you find any more?
Don't know who Rube Goldberg is?
From Wickipedia: "Reuben Garrett Lucius Goldberg (July 4, 1883 – December 7, 1970), known best as Rube Goldberg, was an American cartoonist, sculptor, author, engineer, and inventor.
Goldberg is best known for a series of popular cartoons depicting complicated gadgets that perform simple tasks in indirect, convoluted ways, giving rise to the term Rube Goldberg machines for any similar gadget or process. Goldberg received many honors in his lifetime, including a Pulitzer Prize for his political cartooning in 1948 and the Banshees' Silver Lady Award in 1959."

Did you know that a turkey's wishbone — the one you and your siblings pull from opposite ends to see who gets the middle nodule — is formed by the fusion of the bird's two collarbones? Also called a furcular, the bone serves as the connecting point for muscles and a brace for the wings. During the bird's flapping (yes, turkeys can fly up to 50miles per hour in short bursts), the wishbone acts as a spring to store and release energy. This elasticity is also the reason snapping a wishbone before it dries is so tough.
But, it turns out, the wishbone is more than a fun game for Turkey Day. It also serves as a reminder that birds evolved from a group of dinosaurs. That’s right, turkeys and dinosaurs are related!
Did you know that plants BREATHE? It’s called TRANSPIRATION and it’s actually part of the water cycle.
Plants suck up water in the soil through their roots. The water travels all over the plant, and eventually leaves the plants through their leaves. But, by the time the water leaves it’s in the form of VAPOR or GAS!
If you put a plastic baggy over a plant’s leaf and leave it for a few hours, when you come back, you’ll be able to see water droplets in the bag. This is because the water vapor that the plant breathes out condenses back into liquid water droplets when they touch the inside of the baggy.
