Science & Math Education Videos for All
เข้าร่วมเมื่อ 31 ม.ค. 2017
This channel is created to support future and practicing mathematics, science and technology educators who want to have more engaging lessons. The featured demonstrations are created by UBC educators from the UBC Department of Curriculum and Pedagogy. They are simple, interesting, and can be performed with very limited resources. Yet, the concepts behind these demos are very profound and they are directly related to K-12 science and mathematics curriculum. This work has been supported by the UBC Teaching and Learning Enhancement Fund: tlef.ubc.ca/

The Burning Ships of Syracuse: Science Behind the Legend
มุมมอง 8621 วันที่ผ่านมา
During the Roman siege of Syracuse (circa 214-212 BCE), Archimedes, a renowned Greek mathematician, engineer, and inventor, devised ingenious methods to defend the city. One of the most famous (and disputed) accounts is that Archimedes used a system of mirrors or lenses to focus sunlight onto Roman ships, setting them on fire. But can this be true? Can we uncover the physics behind this story a...

Analyzing the Effect of Radius on Angular Acceleration of Rolling Sprockets Down a Ramp
มุมมอง 56ปีที่แล้ว
To investigate the connections between dynamics and rotational motion, various sizes of sprockets were rolled down a fixed-slope linear ramp, and by measuring the auditory clicks of the sprockets down the ramp, the angular velocity, and hence the angular acceleration, were measured from each trial. From 7 trials of 3 differently-sized ramps, it was found that the hypothesis that the angular acc...

The game in the beginning was surprising
Great models, they really help me to understand the movement of energy, not matter, thanks!
This explanation is incorrect. A high speed does not guarantee a pressure lower than atmospheric pressure. When the hair dryer tilts and blows out air. To keep this ball in the air, there must be an upward force to balance gravity. After the air hits the sphere, its velocity decreases and its pressure increases. At this time, the pressure is higher than atmospheric pressure. The position is in the bottom right corner of the ball in the video. So, the force F1 caused by this pressure points towards the upper left corner of the video. In addition, the air hitting the ball will change direction and move upwards along the sphere. Due to the curvature of the sphere and the linear inertia of air, there is a tendency for air to move away from the sphere along its normal, resulting in low pressure. So a force F2 was generated towards the upper right, which together with the force F2 caused the ball to float in the air. So, this is not the result of Bernoulli's principle. After hitting the ball with air, the speed will indeed increase, but this will not result in the generation of pressure below atmospheric pressure.
Of course the best educational videos have the least number of views.
good
There is a contradiction in your definition of stable equilibrium and your example at 2:20 . In the example , the centre of mass of that figure on a motorbike is ABOVE the point of support (ie. the wire). Yet your definition says 'stable equilibrium' when the COM is BELOW and in line with the resting point , or point of support.
Very well
Where can we buy that light at?
My grandparents have these, they’re so beautiful.
Hey thanks for this video, I have taken inspiration from this experiment you have done and did it myself for my IB physics IA (essay). I'm confident my essay will get good grades as I delved into most of the things in depth and that's mainly from the experiment you did. Simple but effective!
The explanation for finding mechanical advantage using the free body diagram is really helpful, thank you
Cool!
so good
I can't imagine a single one on Amazon being properly calibrated. It's a shame we can't buy nice things anymore.
you guys basically just saved my lab report
1st off you have an awesome accent! I am jealous I wasn't born British, lol. But very good explanation of how this awesome thermometer works!
I'm confused, I had one my cat broke it. It smelt so strong, like chemicals. My daughter walked over to it and got some on her before I could stop her. I took her to the hospital because I didn't know what was in it, or if she got some in her mouth. She was okay, praise the Lord. A lot of people say it has ethanol in it, even the website states it. This smells like straight up motor fluid! Its so strong, I had to throw away a whole basket of clothes because the liquid spilled on them. I am wondering if the older models have something else in them? I got mine for free, it was maybe 30 1:00 years old?
Nice video I have one which I got for my 21st birthday
Your video doesn't have proper SEO. SEO is a must to increase video views.
Hi dear, I hope you are well. I saw that your TH-cam videos are very lovely and very helpful. You have enough of the videos but your video is not getting views because there is some problem with your videos. Your SEO score is very poor and you need optimization for better results.
dammit, I forgot my scoopula... AGAIN! 🤦♂
brilliant video!
I though it was a barometer!
There is no kinetic energy in a moving mass there is force Mv squared kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers MEng
Amazing video! Just discovered this channel, and I feel so lucky
This video has changed my life. My whole outlook on everything that exists in this world, in fact even in the entire universe. I can never look at anything I know the same way ever again. This video represents emotions most humans could never comprehend. But I can. Thanks to this video I have been awakened to many things previously thought unimaginable. Thank you.
omg same
me too
Absolutely outstanding! This video has given me great insight into the matter of Lorentz Force and electromagnetism! Thank you team for creating this!
Good
Omg this is such a great video!!! Keep up the great work y’all!
With the rising temperature of the liquid also the liquid in the balls rises. Does the density of the balls change as well?
Good question. The density of the balls doesn't change, as the glass doesn't expand much under these conditions. So the volume of the balls stays unchanged and its mass as well, so the density of the balls doesn't change in this temperature range. Good question!
Just wow@ creator in all his wisdom and beauty very well explained Thank you
Thank you 🙏
I searched hoping sci-show had a video on this. I didn't find one by sci-show so I clicked here, and he has a sci-show lab coat!

My top float is 28 degrees C, do they calibrate these for different climates around the world!
I am not sure how it would be related to the climate when the thermometer is sealed. I do not think one has to calibrate it to the climate and the temperature measurement is universal.
Beautiful...😍
