Plants

This issue of Big Picture provides lots of interesting information about flowering plants and their uses. 

The plant hormones animation explores the action of indole-3-acetic acid (IAA) and shows how scientists used experimental evidence to explain the role of auxins in a phototrophic response.

 Information on how to do extended science projects and how to conduct them ethically, together with some additional advice for teachers and schools.

Mission to Mars

In this DIY Faraday Challenge, students are asked to work in teams to design and construct the rocket which will transport supplies via Earth orbit to the astronauts on Mars. They are also required to build a system to transport the rocket to the launch site. Students must also show high manufacturing quality...

A wave model of sound

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Recognise that as a sound wave travels forward, the medium it travels through does not.
  • Describe the movement of each ‘particle’ of a longitudinal (sound) wave as the wave moves...

Waves on water and ropes

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Recognise that as a transverse wave travels forward, the medium through which it travels does not.
  • Describe the movement of each ‘particle’ of a transverse wave as the wave moves...

Diet and Exercise

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Explain what humans need in their diet and why.
  • Identify short-term and long-term effects of exercise on the human body.
  • Predict the possible outcomes of eating too much or...

Genes, Genomes and Health

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. In recent years, great progress has been made in genome sequencing and understanding the huge amount of data produced. Our genes play a key part in making us who we are, but how can science help us understand our genetic...

Drugs

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. While providing immense benefits, drugs are not the perfect solution.

They only work on a proportion of patients, sometimes they harm us, and we're not very good at taking them as we should. For some diseases,...

Fat

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 out what they do, not just inside us and other organisms but also in the world around us.  Curriculum...
