This Catalyst article looks at the process of photosynthesis, by which plants make a range of biochemical compounds. The article explains how photosynthesis actually ties in with growth. Respiration is happening all the time in all cells in all living organisms. Taken on its own, photosynthesis adds materials to...

In this practical investigation, students measure the rate of photosynthesis in plants from different habitats (sun and shade), and then consider what this demonstrates about leaf adaptation.

When leaf discs are...

The Earth's population is increasing, but at the same time the amount of suitable farmland is decreasing due to factors including climate change and the growth of cities. Producing sufficient food to feed everyone is a global challenge. This activity sheet builds on students' knowledge of photosynthesis and plant...

Five activity sheets produced by the Institute of Physics (IOP) to accompany the Model Project's Physical Health video.

Worksheet one takes an overview of the topic. Worksheets two - five are targeted at specific sections of the video.

Answers to all the worksheet questions are provided in the Word...

Three practicals produced by the Institute of Physics (IOP) that help students to understand some of the physics used in medical analysis. In addition to the guidance included for specific activities, please refer to the generic health and safety information before commencing any practical activity. This resource...

This video, from the Institute of Physics (IOP), shows medical scientists at work using a variety of sophisticated devices which use principles of physics to investigate what is happening inside the body.

The video is presented as a whole but for ease of use, the following sections are available at the...

A Catalyst article about phytoplasmas which are micro-organisms that affect crop plants modifying their growth. The article looks at the damage that they can inflict on crops which in turn can cause famine. Botanists are seeking to counter the effects of phytoplasma disease and the article looks at laboratory...

A simulation from Science upd8 that looks at how a viral disease spreads in a model population (the school). It is interactive, relevant and involves large numbers of students. There is the potential for family involvement. The simulation continues for around 5 days, after which students can use ICT to analyse the...

Planet Earth podcasts, from the Natural Environment Research Council (NERC) and hosted by Planet Earth online, cover a variety of topics about the world around us. Each podcast reports on two to four different stories, describing research projects and studies, dangers to the environment and wildlife, and proposed...

This book, from Unilever, was produced in the context of the availability of proteinaceous foods and world nutritional requirements. A table of foods with percentage content of protein, fat and carbohydrate is provided – together with a breakdown of the comparative animal/vegetable protein consumption by continent...

This Catalyst article explains how scientists came to understand plants' sensitivity to external stimuli and their ability to move. Mimosa pudica...
