Soil Water: An Introduction

This introduction to soil water emphasises the importance of the pH of soil. For example, each plant has a preferred pH making it important for food producers to recognise the importance of soil pH in growing healthy plants and crops. (A cautionary point – you may wish to challenge their stated limits of the pH scale!) 'Soil water' is part of a larger pack of classroom resources, 'Soil science – Challenging plants'.

Logarithms

This Education in Chemistry article is one in a series that offers tips for teaching maths skills to chemists. Students find logs difficult and modern-day calculators don't help them to develop a real understanding. After exploring logs, pH is chosen as a chemistry topic to exemplify and illustrate their relevance.

Luminescence gives 2D pH images

pH is crucial in many bodily processes. Cutting-edge research in Europe has developed a safe method for imaging the pH of tissue in the human body. This involves using luminescence from microparticle-bound dyes.

Science at your fingertips

Could we really use our smartphones or tablets to make measurements like pH and conductivity in the near future?
