KS2 science: a four-section look at forces, friction and gravity

Examine forces, what they do and how they can be measured, with this four-section programme for Key Stage 2 science. Skateboarder assesses how the various materials used for a skateboard have different relationships with the forces of friction and gravity. Some help to reduce friction, others help to increase it. Parachute Jump looks at skydivers, investigating the forces in action before and after the canopy is opened. Pedal Power investigates where the force comes from to push bicycle pedals and make it move. This section goes into the lab to see a chicken leg being dissected to examine muscles in more detail. Finally, Sliding on Snow shows a primary class the forces of gravity and friction when snowboarding and tobogganing.

A visual journey into the world of bugs, for KS2 science

Examine micro-organisms - or bugs - with a Key Stage 2 science class. This video shows pupils that bugs live everywhere, including on and inside human beings, and it highlights the importance of good hygiene practices. Bug Ballet shows microbes under a powerful microscope dancing across the screen. It's a Bug's Life uses animation and live action to demonstrate the consequences of a child not washing his hands after using the toilet. Yoghurt Live! proves that not all bacteria are harmful. In fact, bacteria is essential in yoghurt production. Using animation, this video investigates the microscopic science of making yoghurt. A Trip to the Dentist shows a primary class just how many bacteria we have in our mouths and explains how brushing our teeth prevents decay. Finally, Where Does all the Poo Go? visits a sewage works, showing what happens after we have flushed the toilet and how bacteria helps to clean the sewage.

How plants survive in different environments, for KS2 science

This five-part Key Stage 2 science video shows how plants adapt to their environments and how they're essential to our lives. What Plants Need reveals to a primary class how botanists can replicate different environments to give plants the right conditions to survive. Leaves Make Food demonstrates through animation that leaves are food factories where photosynthesis happens. Plants We Eat follows an organic farmer harvesting edible plant parts, while Oxygen from Plants shows how plants produce oxygen for us to breathe. And finally, Don't Waste Paper explains where paper comes from, forestry sustainability and the importance of recycling.

Non-reversible changes that create new materials: KS2 science

Explore the non-reversible changes that lead to the formation of new materials, with this five-part video for Key Stage 2 science. Fire! Fire! reveals to a primary class the Hindu festival of Dessehra, which includes explosions of fireworks that result in irreversible chemical changes. Changed For Ever goes into the lab to observe chemical changes, including time-lapse footage of lit candles and the burning of magnesium. Magic Sand follows the amazing changes in properties which occur between taking sand as a raw material and producing finished glass. No Going Back observes two non-reversible chemical reactions in the lab, and What's Cooking? looks at chemical changes in the kitchen through heating, roasting and frying.

Take an in-depth look at the properties of light, for KS2 science

Take an in-depth look at the properties of light with a video for use with Key Stage 2 science classes. Through time-lapse film and animation from space, The Day and Night Show highlights the differences in the 24-hour cycle. Cinema Trip explores light sources, revealing to primary pupils how light can travel through some materials but not others. Inside an Eye goes into the lab to observe an animal's eye being taken apart to find out how it works. Trick of the Light looks back at how the Victorians used mirrors and lenses to set up the camera obscura - a giant camera. Seeing the Light goes into the lab to explain reflection, using mirrors, torches and lasers to demonstrate how light travels in a straight line.

Examine quarries, water cycles and reactive gas for KS2 science

Introduce a Key Stage 2 science class to the properties and uses of the many materials that surround us, including rock, water and carbon dioxide. Rocky Road reveals to primary pupils the processes involved at a quarry, from the rock being blasted out of the ground to the mixing of it with hot bitumen and the laying of it to make roads. Ice Trail looks at the properties of solid and liquid water, as a block of ice is shaped and moulded into a sculpture. And in Melting Moments a KS2 class can learn how heat can change ice from a solid to a liquid to a gas. Rainy Days uses a combination of live action and animation to examine the water cycle and the part played by evaporation and condensation. And finally, All Change demonstrates how solid carbon dioxide reacts when inserted into a balloon, and what happens to a balloon when placed into liquid nitrogen.
