This problem is about what happens to the brightness of two light bulbs when you place a wire across the circuit which essential shorts out one of the two light bulbs.

Do you suffer from eye strain from digital screens like Smart Phones, Computers & Laptops? Me too! Though my day job is being a DOCTOR, I spend my off-time making animations & browsing Reddit in front of digital screens. In this video, I...

Students will learn about the different frequencies along the electromagnetic spectrum. Vivid animation is used to explore the visible spectrum of light and the colors it allows us to see everyday. The video also investigates various...

In this video I take a closer look at the exposure triangle and address some ways it could be improved. The exposure triangle has been a popular learning tool for beginners for decades, but unfortunately, since ISO is not part of camera...

What is the difference between DIRECTIONAL and NON-DIRECTIONAL HYPOTHESES? What even is a HYPOTHESIS? Every experiment starts with a hypothesis - predicting the outcome of the experiment. Directional hypotheses predict the direction of a...

"ISO is the sensitivity of the image sensor." "Increasing ISO directly increases noise." "ISO is part of the exposure triangle." "ISO controls the amount of light the camera collects." Chances are, you've heard these statements at least...

A conversation with one of TIME Magazine’s 100 Most Influential People, Natalie Batalha, the Kepler mission project scientist at NASA’s Ames Research Center in Silicon Valley.

As Psychology is a science, it uses the experimental method in a similar way to Physics, Chemistry and Biology. However, because of the subject matter Psychologists are studying, it can sometimes seem a bit confusing. Under the hood, a...

In this lesson, you will learn how to make exciting patterns with your Code Cube.

Gravitational microlensing events are revealing the mysteries of rogue planets, but what are they, and how does it work? And what role does the Nancy Grace Roman Space Telescope play in helping us spot more rogue planets in the future?

This code comes from a course student [Arthur] working on a challenge. The challenge was to blink 3 LEDs in sequence back and forth and use two potentiometers to adjust the timing of the blink and the brightness of the...

In this video, we explore how our brain processes visual information and how it can be tricked by optical illusions. From moving images to motion illusions, we learn how patterns, colors, and brightness play a role in shaping our...

An example of using Pulse Width Modulation with Arduino.

This video explains the concept and importance of green screens in creating visual effects and technology. It discusses how green screens use Chroma Key or color keying to isolate a specific color and make it transparent, allowing for...

During its K2 campaign, NASA's Kepler spacecraft observed the eighth planet in our solar system, Neptune. Kepler detected small changes in Neptune's brightness caused by the planet's daily rotation, the movement of...

In this video, the teacher demonstrates how to create a beautiful Ruby rubber plant painting on canvas. She guides viewers through the process, from drawing the leaves to mixing and applying the acrylic colors.

Fading Multiple LEDs in Sequence with Arduino :: Viewer Question #4

Today, there's so much misinformation about how photography works: the science, theory, and technology behind how images are formed. In this video I wanted to provide not only the definitions of key photography concepts, but how they...

A full fledged tutorial for an RGB LED strip light connected to 2 potentiometers. One potentiometer changes speed of pattern, whereas the other changes brightness of LEDs. Uses Arduino Uno microcontroller with Arduino IDE code.

The decade from 2000 to 2009 was the warmest in the modern record. "Piecing Together the Temperature Puzzle" illustrates how NASA satellites enable us to study possible causes of climate change. The video explains what role fluctuations...

Upon viewing the Stars and Galaxies video series, students will be able to do the following: Explain that our solar system is part of the Milky Way galaxy. Understand that the Milky Way galaxy is huge and contains billions of stars....
