The definitive answer about the direction water swirls in two hemispheres
Sync the videos yourself: http://toiletswirl.com

For the record Destin and I repeated the experiment 3-4 times each in each hemisphere and got the same results every time.

The idea that water going down a drain or flushed down a toilet swirls in opposite directions in the Northern and Southern Hemispheres has a long history. But few have ever done the experiment. Destin from Smarter Every Day and I performed identical experiments in the Northern and Southern hemispheres. What we found is the direction of water swirl in a toilet, sink, or bathtub is determined by other sources of angular momentum. However if the body of water is big enough, e.g. a kiddy pool, and left still for long enough (at least 24 hours), then the Coriolis effect is observable with water swirling counterclockwise in the Northern hemisphere and clockwise in the Southern hemisphere.

Gordon McGladdery did all of the sound design for the video. We used two songs from other artists (licensed of course). Derek split the first one up so it fades from video to video, and Gordon split the instruments up on the second one. There are violins on one video and percussion on the other for example. It's really neat.

The neat earth animation at the beginning and the synchronizing timer was made by http://eisenfeuer.com/. He also made still images of the earth from the top and the bottom.

Thanks to Vanessa for filming in Sydney: http://youtube.com/braincraftvideo

MORE INFO:

There was a study performed at MIT years ago (http://web.mit.edu/hml/ncfmf/09VOR.pdf) that explained the physics involved. We repeated some of these demonstrations, but on opposite sides of the globe…and in a way that can be easily understood.
This site is a great resource on the Coriolis effect and ways people have gotten it wrong:

Have you ever wondered what life would be like if you could not see or hear anything? That was life for a woman named Helen Keller. In this video for kids, you will learn about the life and accomplishments of this incredible historical figure. Even today, her story and lasting impact are inspiring.

Helen Keller was born in Alabama on June 27, 1880. When she was a little under 2 years old, she fell ill to meningitis and lost both her sight and hearing. She hadn't yet learned how to speak. Her parents knew she would need special help and found that assistance through Anne Sullivan.

Anne Sullivan had been blind herself once but received it back after a surgery. She wanted Helen to live a normal life and began teaching and helping her at age 7. She would remain Helen's helper and companion for over 50 years! Anne first taught Helen words by placing an object in one of Helen's hands and using sign language to spell out the word in the other hand. In other words, she used Helen's sense of touch to teach her words.

Another teacher named Sarah Fuller helped Helen learn how to speak by using the vibrations of words on her own lips. Helen learned how to feel the vibrations and get a sense of how her own lips moved to make her own sounds. Eventually, she was able to speak as anyone else. She also learned how to read using Braille.

We hope you and your student(s) enjoyed learning about Helen Keller! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

Permutations are easy to understand...but take time to get to why we work them out the way we do so you can understand them better. This video also looks at how permutations differ from combinations, and well as looking at simple permutations, permutations with limited spaces, permutations with repeats, and permutations in a circle.

Do you recognize the story, The Tortoise and the Hare? This story is called a fable. In Fables for Kids, you will learn about this unique type of story and the elements that must be included. Can you think of any of those elements off the top of your head?

All fables have five specific characteristics. They must be fictional, meaning that it is an imaginary story. Generally, these stories are fairly short. The element you probably knew already is that fables teach a moral lesson. "Slow and steady wins the race," for example, is the lesson we learn from The Tortoise and the Hare. In all fables, the main characters are always animals that act like humans. Finally, the setting of a fable is always outside.

Where did fables come from? Aesop, a slave of African decent who lived in ancient Greece, had a collection of fables that we now call Aesop's fables. Historians are still unsure whether he wrote all the stories himself or simply gathered them from other sources. Even though he lived a long time ago, his stories were passed down to the present day!

We hope you and your student(s) enjoyed learning about this special genre of stories! If you want even more practice, head over to our website and download one of our many free lesson plans about reading, full of activities, worksheets, and more!

Have you been on a see-saw before? The weight has to be the same on both sides for the see-saw to be balanced, otherwise it would be tilted to one side.⚖️

Balancing equations works in the same manner and a student would have to apply the concepts of addition, subtraction, multiplication and division altogether in order to solve the equation. Learn more about the concept of balancing equations from Mrs Monica Leong in our P1 Math lesson!
