Gelli Baff, a crystalline powder, has been dumped into a bathtub filled with water. How can you force the hydrogel to go down the plughole in order to drain the bathtub? 

In this investigation, students learn about swelling reactions, balanced reactions, and polymerisation. Students should be able to...

Produced by the former Department for Children, Schools and Families, this guide supports the delivery of Diplomas. It explores ways to encourage both male and female learners to consider qualifications and careers that are not typical to their gender. It suggests activities that consortia can carry out to engage...

This London Engineering Project paper, from the Royal Academy of Engineering, describes the processes and practices for developing gender neutral and culturally appropriate engineering activities in schools.

This collection aims to support teachers in the delivery of career-focussed lessons and events. Combining material for students with comprehensive teacher guidance, these resources can help teachers to confidently explain the opportunities available to their students. Highlights include:

• Top Ten...

This collection holds a variety of reports about education issues in general, rather than about specific subjects. They include reports which discuss the development and importance of vocational courses, progression from Key Stage Four to A Level and continuing professional development for teachers and technicians...

Generation Logistics is an initiative from the Chartered Institute of Logistics and Transportation to demonstrate to students and teachers the relevance of the logistics industry to their lives and the wide variety of career opportunities available.

The resources contained within this collection apply real-...

This series of logic puzzles requires students to read a story and extract relevant pieces of information to determine which person did what action in the story.

The logic puzzles can help build students' problem solving skills, extract information from longer more involved situations and break larger...

This group of mathematical problem-solving activities use the context of Norwest, a small chain of mini supermarkets serving small towns in the North West of England. The activities show how mathematics can be applied to practical situations in the world of logistics.

This group of packing problems, sometimes referred to as bin packing problems, show how mathematics can be applied to practical situations in the world of logistics.They are an accessible gateway to solving problems in such a manner to find the greatest or least solution. Once students are familiar with simple...

Produced by the Technology Enhancement Programme (TEP), these images are useful for adding to documents, presentations or for use with an interactive whiteboard. Mainly simple line drawings, they can be cut and pasted into documents and image processing applications. The images in this resource are related to the...

This article on Genetic Databases appeared in Biologist magazine in 2001. The resource is provided by the Association for Science Education (ASE).

What we eat; how we function (even to the smallest active molecule); every creature, microbe or plant that lives and grows in, on and around us - all these...

Produced in 2015, these resources look specifically at how genes can be altered in plants and how bacteria are central to genetic engineering techniques. Genetically modified (GM) crops offer the potential to help improve food security though this still remains...

Produced for the Citizen Science project, this resource enagages students in the debate around genetic testing and screening. It is suitable for students aged 14-16 and post-16. The activity provides an opportunity to investigate genetic disorders before considering a number of statements and situations concerning...

A number of scenarios are presented to encourage debate around genome sequencing. All teaching materials are provided.

• The interaction of genetic and environmental factors in influencing phenotype
• Ethical implications of genetic screening
