This activity details three ways to dissect a flower in order to identify and name the different parts. Linked to plant lifecycles, further activity ideas can be found in the full resource Parts...

By using a helical spring and varying the mass on the end of it, students can time the period of oscillation to calculate the acceleration due to gravity.  This can be done by plotting the extension (e) by the time period squared (T²).  This would be good to use computer software to assist with this....

By using a constant head apparatus or similar you will investigate the shape of a water path projected through the gravitational field of the Earth to find the acceleration due to gravity. This would benefit from using slo-mo filming or photography, or even to introduce students to a travelling microscope.

This investigation uses a linear air track that is tilted to a slope to calculate the acceleration of an object due to gravity.  SUVAT can be used to calculate this value, and datalogging, especially using light gates can be used. Students can also use a protractor to measure angles which can be varied.

This...

Produced by the Royal Observatory Greenwich, this booklet shows how to use Kepler’s third law to calculate the mass of the black hole in the centre of the Milky Way. Included is an online video that discusses what is inside a black hole. Equations and physical terms are introduced and discussed. Students are tasked...

Chemists analyse the tiny traces of substances which form a fingerprint. This allows them to determine drug abuse and as well as the age, gender and diet of an individual.

This Nuffield Working with Science unit was designed to encourage students to study fire in the context of safety at home, fire prevention and the role of the Fire Service.

Guidance for teachers and technicians...

This resource presents some real seismic data recorded before a volcanic eruption and allows students to locate some of the resulting earthquakes by use of graphs and maps.

This resource uses the scenario of the ‘Safe at Home’ scientists are developing a new range of fire extinguishers to help families protect their homes from fire. They have heard carbon dioxide might be useful but would like you to help with their investigation.

In this activity children observe irreversible...

In this predict-observe-explain activity, students explore different ways of extinguishing a flame with some surprising results. The lesson is introduced with the video of engineer Yusuf Muhammad. Yusuf is developing a revolutionary new household fire-safety device, incorporating the techniques of professional...

This video demonstrates how adiabatic compression of air can produce enough heat to ignite cotton wool.  The auto-ignition temperature of cotton wool is approximately 400⁰C.  The video could be used to explain the way diesel engines work.

This Catalyst article looks at fireworks and their history, how they are made and set off, and what gives them their colours and effects. The basic chemistry used in fireworks is looked at and how they work once the fuse is ignited.
