In this math video we will solve a math problem by comparing data sets using mean and MAD. We will understand that mean represents the average of a set of data. We will understand that MAD represents the Mean Absolute Deviation of a data...

Brit looks back on our seventh month on Nature League, when we explored the theme of plants.

Students will learn how the structures of plants such as roots, stems, and leaves enable them to live and grow. Real-life applications show how these plant structures are useful sources of food, building materials and medicine. Other...

This engaging series of videos uses colorful animations and on-location footage to illustrate some of the amazing ways plants reproduce. The reproduction processes in bryophytes, ferns, gymnosperms, and angiosperms are highlighted....

This video provides a brief overview of the evolution of life on Earth. It discusses the emergence of prokaryotic cells, the development of photosynthesis and the increase in oxygen levels on Earth. It also explores the origin and...

In this video, we explore the fascinating world of flowering plants, also known as angiosperms. We learn about the diverse range of flowers, their vibrant colors, and various shapes. This video is part of the 10-part series, Classifying...

This fascinating program takes students on a journey through time as the history of life on Earth is explored. From the dawn of life to the existence of advanced vertebrate animals, each of the major periods of life are investigated....

A video created for, and aimed at primary school science students learning all about plants. This video explores different types of plants from land plants to underwater plants.

It describes the events starting from pollination to formation of fruit.

It explains the basic characteristic features, types and common examples of gymnosperms.

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've already introduced angiosperms in a previous tutorial, but there is an overwhelming diversity within the angiosperms that must be investigated. Let's take a look at all of the clades within the flowering plants, especially monocots...

In addition to learning about the structure and characteristics of seeds and plants, this program takes viewers to different locations around the world world. They'll learn about the diversity of plants throughout the various land...

How did dinosaurs get their names? What were the dinosaurs like? How long ago did they live? Can a dinosaur be created from DNA? Did they take care of their young? Why did they die out... or did they? This clip explores the above and...

For all of human history, we've been aware of heredity. Children look like their parents. But why? When Gregor Mendel pioneered the field of genetics, he began to try to answer that question, and now that we know about chromosomes, all...

This video provides an overview of the plant kingdom, highlighting the diversity and importance of plants on Earth. The video then discusses different categories of plants, including mosses, ferns, conifers, and flowering plants, and...

Plants are extremely complex and diverse - there are thousands of species. In fact, there are probably somewhere around half a million different species. And these are just the ones we know about - there are no doubt many more that...
