Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they...

Using real world demonstrations and colorful graphics, Real World Science: Light teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light,...

The world is said to be a big place, but the universe is much bigger and what’s more, it’s expanding all the time. How do we know this? Because of the evidence provided by red shift.

Revealing the Hidden Colors of the Microcosmos

Plants, unlike most living things, produce their own food through a process called photosynthesis. Photosynthesis means 'making using light'. Plants use the energy from the sunlight to make food. The food matter comes from carbon dioxide...

The video is a lecture presentation on the topic of the expanding universe. The speaker discusses evidence and the Big Bang theory, which suggests that the universe began from a small, dense region and has been expanding for...

The video discusses the concept of reflection, including the difference between specular and diffused reflection and how light interacts with irregular surfaces. It also includes a quiz to test the viewer's knowledge.

We just learned about electron microscopy, so what was the next major innovation in microscopy in the 20th century? That would be fluorescence microscopy, of both the widefield and confocal varieties. How does this work? What is...

Plant Physiology and Chemistry Set: 3. This clip examines the chemical structure of chlorophyll and looks at where and how this molecule assists in carrying out photosynthesis.

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...

Was the orange tree named after the colour or was the colour named after its fruit? And why are things certain colours anyway? How do our eyes see colour? And is it colour or color?

How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal. Transmission, reflection, refraction, diffraction,...

Almost all life either directly or indirectly depends on one of the most important biological processes on the planet - photosynthesis. Through easy-to-understand graphics and colorful animations, the complex chemical process of...

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 as...

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...

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,...

Four mechanical wave graphs are introduced and used to understand and demonstrate transverse waves, longitudinal waves, wavelength, and period.

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 as...

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...
