What happens when microbes talk to your brain? The video "How Bacteria Rule Over Your Body - The Microbiome" is a resource included in the Biology topic made available from the Kurzgesagt open educational resource series.

Students learn about geotechnical engineers and their use of physical properties, such as soil density, to determine the ability of various soils to offer support to foundations. In an associated activity, students determine the bulk densities of soil samples, and assess their suitability to support foundations.

Students determine the mass and volume of soil samples and calculate the density of the soils. They use this information to determine the suitability of the soil to support a building foundation.

The theory of evolution explains how the enormous variety of life could come into existence. How it is possible for primitive life forms to spawn the millions of different creatures, that exist today. Unfortunately, evolution is often misunderstood, because it's mechanisms seem counter intuitive. By using visualizations, infographics and appealing characters, the viewer is more likely to understand it the complex information. More than that, by presenting the information in an entertaining way, the information is more likely to sink in The video "How Evolution works" is a resource included in the Biology topic made available from the Kurzgesagt open educational resource series.
