• TLF-IDM021645

This short entertaining video, narrated by ‘Sam the Lamb’ and 'Professors' Madeleine and Daisy test which fabrics burn easily and which fabrics are the most flame resistant. Sam and his science team test the flammability of a range of synthetic and natural fabrics including polyester, polar fleece, cotton and wool.

This six minute video segment from Catalyst Two compares two beaches, one with white squeaky sand, the other with darker non-squeaky sand and their sand studied under a microscope. Dr Tim Senden attempts to shed some light on this mystery with the use of a visual model. Sand avalanches and the production of sound come into ...

This 7 minute video segment from Catalyst describes an excellent example of how biologists have worked to investigate and solve a problem of an invading species of sea urchin that was devastating a marine ecosystem. The scientific approach to develop a biological control needed to rely on technologies such as radio tracking ...

Students use this resource consisting of one page with a diagram of a lever whose length can be varied. A weight is then applied to the lever and students can see whether the force was sufficient to lift a crate. This demonstrates that forces can cause a lever to turn about a pivot and that the turning effect of a lever ...

In this simulation students select an object made of one of two materials (either iron or aluminium) and use magnets to guide the object through a maze. Engages students while they learn that aluminium is not attracted to magnets but iron is.

In this simulation students select and move a battery, switch and two light bulbs to positions around a circuit so that the light bulbs are in series with each other. Students receive feedback if their circuit is not a functioning series circuit. Students drag and drop a battery, switch, and two light bulbs into position ...

This nine and a half minute video segment from Catalyst explains that relatively recently times we have got the technology to look for exoplanets. Astronomers have now uncovered more than 350 planets orbiting other stars. These worlds, known as exoplanets, can be pretty weird places. This program discusses a theory to describes ...

Students use this resource consisting of one page with diagrams of Mars, Earth and Jupiter. Students can select any combination of planets and then 'drop' the crates to note the effects of the different gravity forces because of the different masses of these planets. Students should be able to conclude that gravity is a ...

Students learn about the application of light refraction by completing a series of tasks based on light refraction using both concave and convex lenses.

• TLF-IDM016221

This resource is in the style of an 'authentic' scientific investigation. The investigation is set in a crime lab where finding the densities of the various items can solve the crime. The tool enables students to explore mass and volume for a variety of solids and liquids and hence determine their densities.
