Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time...

Indigo may be a very vague and unnecessary color, but it has an interesting history that involves some plants, turmoil, and Isaac Newton's interest in the number seven. Hosted by: Hank Green

Appearing by telepresence robot, Edward Snowden speaks at TED2014 about surveillance and Internet freedom. The right to data privacy, he suggests, is not a partisan issue, but requires a fundamental rethink of the role of the internet in...

What scientific thinkers and achievements have led to vast improvements in optics over the centuries? Discover the fascinating ways that our understanding of light informs the world in which we live.

A mini-lesson on observational patterns.

Jessi and Squeaks love watching clouds and birds fly way up in the sky! But why is the sky blue?

In this video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of energy....

Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution...

From corundum to alexandrite, there are rare minerals have multi-colors caused by how they form their structure!<br/>

In today’s lesson, we’ll explore what surface area really means, how nets help us see every face, and how to find surface area for rectangular prisms, triangular prisms, and parallelogram prisms. Then you’ll learn the shortcut formula SA...

How to Find the Volume of a Prism | Math Defined \ 7.G.B.6 Today we’re learning how to find the volume of prisms, including rectangular prisms, oblique prisms, triangular prisms, and even a hexagonal prism. We’ll use the formula V = Bh...

A video entitled "Volume of Composite Shapes" which shows how the volume formulas vary based on the shape of the base.

A video entitled "Rectangular Prism Cross Sections" which shows the shape of various cross sections of the 3D figure.

Pupil outcome: I can recognise and name pyramids and prisms and describe their properties. Key learning points: - A prism is a 3D shape that has identical opposite polygon faces at each end which are joined by rectangular faces. - A...

Pupil outcome: I can appreciate that all prisms have two congruent polygonal parallel faces (bases) with parallelogram faces joining the corresponding vertices of the bases. Key learning points: - Prisms are 3D shapes with a...

Pupil outcome: I can calculate the volume of prisms. Key learning points: - The shape and area of the base of a prism can be found. - The area of the cross-section multiplied by the length gives the volume of the prism. - This can be...

Pupil outcome: I can use the constant cross-sectional area property of cylinders to determine their volume. Key learning points: - A cylinder is not a prism but has a similar structure. - The formula for the volume of a cylinder can be...

Pupil outcome: I can efficiently calculate the surface area of other prisms. Key learning points: - The surface area of a prism is the sum of the area of all the faces. - The net of a prism can help find the surface area of a prism but...

Pupil outcome: I can use my enhanced knowledge of surface area and volume to solve problems. Key learning points: - The surface area of many solids can be calculated by a known method. - The volume of many solids can be calculated by a...

Pupil outcome: I can use my knowledge of perimeter, area and volume to solve problems. Key learning points: - The volume and surface area of shapes made from prisms and cylinders can be found. - The volume and surface area of shapes made...

Pupil outcome: I can find the surface area of 3D shapes in an efficient way. Key learning points: - The surface area of a 3D shape is the sum of the area of all the faces. - The net of a prism can help find the surface area of a prism...

How to find the cross section. We investigate how to predict what shape the cross section will be when it is parallel or perpendicular to the base of a cone, cylinder, cylinder, or prism.
