This student sheet invites students to consider lignification in detail. Students take thin sections from successive internodes of the shoot and calculate the lignification index of each section. These can then be compared with sections from other parts of the plants to consider where lignin is deposited in other...

This resource provides a set of videos and a practical investigation aimed at supporting working scientifically in the classroom and relating it to real world experiences. In the first video Professor Brian Cox joins a teacher to find out how to set up and run an investigation to find out how exercise affects heart...

This physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...

In this practical activity, from the Institution of Engineering and Technology, students investigate the properties of smart springs and see how they might be used as muscles in a robotic arm. This activity can be used as an extension to the related activity ‘...

Children are challenged to test home-use plastics by submerging them in water and applying force before recording their findings using a simple identification chart to name them.

Children are asked to investigate home-use washing products to find out which ones achieve the best result on stained fabric, by running a fair test. Fabric samples are left to soak in a container of warm water with selected washing products, before being removed, rubbed and then rinsed. Children are encouraged to...

In this experiment, from Science & Plants for Schools (SAPS), students are required to make observations about wild oat seeds. Using a petri dish, glass jar, filter paper and water, students can recreate the conditions of a greenhouse. They can then observe the changes to direction of the awn (the long hair at...

This resource looks at the impact of climate change, in particular flooding and drought, and how science can be used to mitigate against it. Students first explore perceptions about climate change, then look at ways to communicate the significance of climate change to different groups of people. They then explore...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). One of the most important questions facing us all is how we will use the planet’s energy resources over the coming decades. Many people believe that wind power can make a vital...

This resource looks at the two main drivers of sea level change - isostasy and eustasy. Each of these terms is explained and a worksheet covers both ideas in three practical demonstrations.

In the first practical, which includes both isostasy and eustasy, students undertake experiments which prove that...

This resource explains what a salt marsh is and how they record sea-level changes. As salt marshes are zoned by tidal inundation, salt marsh plants and sediments can then record changes in sea level as the zones move horizontally in response to vertical changes in sea level.

In a practical experiment,...

A CREST investigation produced by Practical Action, in collaboration with the British Science Association, for primary pupils. 

Students find out  how farmers in Bangladesh can earn more money for their family by turning milk into yoghurt.  They go on to make a range of different flavoured yoghurts...
