How does the hot chocolate effect work? The weird pitch frequency coming for your coffee. The speed of sound changes when water and a powder mixes. Air is created and slowly fly out of the system but air changes the bulk modulus and...

Overview of the relationship between frequency and period in waves.

So we've made it all the way to the 20th century with the history of astronomy. Plenty had to happen to get us to that point, but the most amazing stuff is yet to come! Shortly after Einstein did his best work, a guy named Edwin Hubble...

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...

Electrical engineering encompasses a broad range of subdisciplines included electronics, RF, controls, signal processing, instrumentation, power, and much more. This video covers a quick overview of those fields and then goes into the...

Electrical engineering can be broken up into various concentrations. The main one's I discuss in the video are power, electronics, RF, and controls. Students who enter into electrical engineering will all take mostly...

Probability is all about using mathematics to describe chance. Probability means how likely it is that something will happen. We use a probability scale to know, more precisely, when an event occurs.

In this video, the teacher explains how to calculate conditional relative frequencies by identifying the part and the total. Using examples of squares and a two-way frequency table, the teacher demonstrates how to compute percentages and...

Resonance is introduced and demonstrated using a “singing rod”, a swing, a goblet, a hollow tube in water, a hollow tube open on both ends, a seashell, a broken speaker, a human body and a key fob, and a shorter “singing rod”....

In this lesson, you can learn about adverbs. What do adverbs do? What’s the difference between adjectives and adverbs? How do you use adverbs in English? You can learn the answers to these questions in this...

What are some of the limitations of current climate models?

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...

I want to investigate how population has changed in these cities…but these numbers are just numbers. They don’t mean anything to me. In this video, we are going to discover how great bar graphs are for providing us with a clear visual,...

Shows how a toy can open garages. I don't condone malicious hacking of gates, garages or other property. The point of this video was to discuss how it could be done using fairly basic technology like this toy that was originally intended...

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...

This video guides students through the process of measuring the length of strings around pumpkins and recording their measurements using mixed numbers. They then organize the data using a T chart and construct a line plot, representing...

In this video, we learn how to determine the count and probability of the union of two events using a two-way table. The example used is the Lucky Envelope game, where we have blue and red envelopes with different contents.

In this video, the teacher explains how to display data using a histogram. They discuss the difference between a histogram and a bar graph, and demonstrate how to create a histogram by grouping data into intervals and representing the...

Upon viewing the Light video series, students will be able to do the following: List some of the reasons light is important to all living things. Understand that light is a type of energy. Describe how light behaves both as a wave and...
