This video introduces a reliable technique to demonstrate tissue culture and totipotency, and shows how best to use this protocol with your students.

Unlike animal cells, many plant cells are totipotent, meaning that...

Produced in 2014, this resource looks at cell signalling when the hormone adrenaline binds to receptors on the surface of the target cell. The resource sheets describe how the original hormonal signal is amplified through a cascade reaction.

...

This kit and their associated resources are designed to help teach about double-slit and diffraction patterns.

Before teaching this, students should:

  • be familiar with constructive and destructive interference;
  • be aware that we get diffraction when a wave travels through a gap;
  • ...

Fat

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

Fat is a word that carries a lot of weight, conjuring up topics as diverse as obesity, hibernating animals, and what we eat and how we cook it. This issue of the Big Picture looks at the fats and lipids to find...

 

This guide has been developed through the STEM Subject Choice and Careers Project. It is designed to help teachers, learners, employers and anyone involved in work experience develop strategies for creating good quality placements for young people age 14–19. The question and answer format has been used to...

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 by the Wellcome Trust Sanger Institute, this multimedia resource explores the five major stages of the malaria lifecycle, highlighting the role of the Plasmodium parasite at each stage. The resource predominantly focuses on Plasmodium falciparum but does also make reference to other Plasmodium species...

This resource looks at how cutting edge science is being used to answer archaeological questions, as well as solving present day problems, such as the identification of meat in processed foods. Analysis of mitochondrial DNA was performed, at the University of York, on samples from skeletal remains unearthed by the...

Produced in 2015, this resource looks at glass microspheres, which contain radioactive Y-90, and are currently being used to treat liver cancer in humans, where their chemical durability is of prime importance.

This...

The aim of this experiment is for students to be able to determine for themselves the threshold voltage needed to activate a range of LEDs of different colours. From these values, combined with a knowledge of the wavelengths of each LED, students can plot a graph to determine a value for Planck’s constant. The...
