Supercontraction of Hair

This Unilever Laboratory Experiment, published in 1967, describes an experiment to measure the contraction of hair in a hot solution of phenol. The procedure is based on a school-made apparatus to measure the changes of length. The results are discussed in terms of hydrogen bonding and disulphide bonds between...

Supercooled water - explained

This video explains how nucleation in impure water helps it to transition from liquid to solid, yet in very pure water this is far harder.  Supercooled water (water cooled below its freezing point, yet still liquid) is made. The bottom of the bottle is hit against a table and ice crystals instantly form.  This is...

Superman's Not Dead

This Catalyst article investigates x-rays. X-rays are used in security scanning and medical diagnosis. Efforts are always being made to reduce the hazard of working with these electromagnetic rays.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 2.

Supermarket Car Parks

These activities from Cre8ate maths explore the efficient use of space in car parks. These are two-dimensional ‘best fit’ problems which require logic and a systematic approach to find effective solutions. They give students the chance to devise and test out strategies using systematic trial-and-improvement...

Supernovae

This animated clip explains that the Crab Nebula that we see today was from a supernova in the year 1054. The star that went supernova is now a neutron star with very high density. The clip explains that elements are created in a supernova that go on to form planets and life itself.

Superpillars assemble - activity 2 - the life cycle of moths and butterflies

In the second activity of the Superpillars Assemble, pupils are introduced to butterfly and moth habitats and their life cycle with a narrated PowerPoint presentation. They then complete an activity to construct the life cycle of a butterfly and describe which part of the plant a butterfly caterpillar might eat,...
