Clouds manifest moisture condensed in the air. In this program they are appreciated and pondered. Clouds give clues to wind direction, humidity levels, weather patterns, and they just make pretty sights. We look at the basic type of...

We've been looking at bacteria for a few centuries now, so how do we categorize them? We love to classify things and put them in groups, so how does that work for bacteria? Well let's learn about Gram-staining, antigens, other phenotypic...

The way that humans communicate is very complex. We have an innate ability to understand and formulate language. As one might imagine, the accompanying brain activity is also quite complex, involving several different regions with very...

Describes the working principle of a One-vs-One (OvO) heuristic method.

Creating an Intelligent Chatbot

We've learned about the types of plant cells, and the types of plant tissues, so the next step up on the hierarchy of organization is organs and organ systems. Plants have these too! The stem, the leaves, the roots, these are all...

We took a look at aerobic respiration in the biochemistry series, and we know that it requires molecular oxygen to occur. But there are other forms of energy production that do not require oxygen. Those are anaerobic respiration and...

We just learned about gymnosperms, and the incredible evolutionary advantages they had over their ancestors. But the next leap forward for plants was even more impressive. Angiosperms are flowering plants, so any plant with flowers or...

We just learned about X-linked genes, but what about gene linkage in general? If two genes are on the same chromosome, we can say that they are linked. Are they always inherited together? Can the alleles rearrange in some way? Well don't...

This live-action video program is about Kingdom Protista. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated...

There are a lot of species in the fungi kingdom. How many? Over five million! That's a lot of fungus to sort through, so how do we keep things organized? Well we may remember learning about phylogeny and taxonomy in the biology series,...

This is a video on the classification of living organisms. The video explains how classification is useful for studying and understanding relationships between different groups of organisms. It goes on to explain the traditional...

It define taxonomy and systematics. It explain the application of taxonomy. It list the universal rules of nomenclature.

This live-action video program is about Kingdom Plantae. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated...

How exactly do molecular biologists figure out all this stuff we have been learning? How do they do science with huge molecules like DNA and proteins? How can we gather empirical data about such molecules? Let's take a look at one...

This nugget classifies fruits into different types.

Why do we sleep? Most people would say that it's because our bodies need to rest. And that's part of it, but is that the whole truth? What about dreaming? What is that, why do we do it, and what do they mean? Let's get a closer look at...

Classifying triangles based on angle properties.

How do we categorize drugs? How do we name them? This is quite a bit trickier than one might think, because there are different ways we might want to categorize them, each of which has its own application. Any drug also has multiple...

This video discusses the traditional and modern methods of classifying organisms based on their similarities. The video explains that the classification of organisms is essential to understand the relationships between different groups...

It explains the characteristics of an element and talks about elements such as metals, non-metals, metalloids and noble gases.

Let's do a quick review of the human brain, introduce a couple new things, and be right on our way learning about brain function and behavior!

We just learned about plant cells, so now it's time to learn about how these different types of cells come together to form all the different tissues in the plant. There is ground tissue, dermal tissue, and vascular tissue. What do they...

We learned about the structure of the eye in the Anatomy and Physiology series. But how do we process visual information? Light hits the retina at the back of the eye, and then what happens? Well quite a lot, to be honest! We have to go...
