The Drinking Bird Clock

Welcome back to my blog. This post is for the third Action Project of the STEAM class Light, Sound, and Time. This unit, Time, has been all about how we perceive time and what it actually is. We first questioned when time originated and why we believe time began directly after the Big Bang. Then, we looked at older methods of telling time such as using the position of the sun for a sundial. We also looked at longitude and latitude and how we determine our position because of it. For determining latitude, you can use the North Star if you are in the Northern Hemisphere or a sextant which is a device that uses mirrors to find the angle of the sun to the horizon. For determining longitude, you can use time zones and Greenwich Mean Time (GMT). To continue our examination of time-telling devices, we spent time studying pendulums and the Foucault pendulum which is a pendulum that can rotate 360 degrees and show how the Earth will rotate beneath it if it were at the North Pole. For Field Expe...

Diddley Bows: One-stringed guitars

Welcome back to my blog. This post is for the second Action Project of the STEAM class: Light, Sound, and Time. This unit, sound, was all about how sound is made and what happens for humans or animals to perceive it. Sound travels as a longitudinal wave and is explained as vibrations coming from a source that we perceive to be sound. To start, we examined how the human ear worked and our range of audible frequencies compared to infrasound and ultrasound which humans can’t hear. We then looked at the speed of sound and how it changes based on the medium it travels through. Following the understanding of how sound travels, we investigated traveling faster than the speed of sound or breaking the sound barrier and also the Doppler Effect. Lastly, we looked at stringed instruments like guitars and found how they make sounds. We also had one Field Experience at Guitar Center to look at the guitars and other instruments there. For this Action Project, the task is to create a diddley bow which...

Pinhole Cameras: How do they really work?

Welcome back to my blog. This post is for the first Action Project of the STEAM class, Light, Sound, and Time. For the first unit, Light, we started by questioning what would our life look like without light. We then learned how light can act like a particle and a wave, how light equals energy, and about the electromagnetic spectrum. This unit helped us understand the importance of light in our lives and all of its uses. We also learned about the human eye and how it takes in light to create an image in our heads. Color was a big part of this unit because it is a very small part of the electromagnetic spectrum humans can actually see. This part of the spectrum is called the visible light spectrum. We used trigonometry to solve problems of waves, the unit circle, and similar triangles. For this Action Project, we were asked to create a pinhole camera and use it to capture an image. My pinhole camera is made from a cardboard box and a lens made out of a soda can. I hope you enjoy reading...
