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.

Ecology and Simpsons Diversity Index

These activities allow students to model how environmental scientists compare diversity in different ecosystems by using ordinary playing cards as ‘species’ to generate data to calculate Simpson’s Diversity Index.   This can be completed in a single lesson. Some students find the concept of species diversity quite...

From idea to career: explore 12 areas of engineering

A closer look at 12 different engineering disciplines to help students work out which area(s) might be right for them.

Engineering is a diverse, wide-reaching sector and it can be hard to decide which of the many areas to pursue. In this booklet aimed at 14 to 19-year-olds, you will find an overview of...

Engineering career route maps

Opportunities for engineers exist at all levels and these career route maps from Tomorrow’s Engineers show various routes through education and training to become a professional engineer in England, Northern Ireland, Scotland and Wales.

Engineering careers notes for teachers

There is a high demand for engineers in the UK – in fact engineering is one of the most in demand jobs globally. From apprentices to technicians; graduates to postgraduates – engineers are needed at all levels, in a wide range of sectors.

This four-page leaflet from Tomorrow’s Engineers helps teachers...

Football in science teaching

What is the perfect curve of a ball’s trajectory, what must the ideal turf be like, and what’s the CO2 balance of the UEFA European Championship? From the measurement of the mass of the air inside the ball, to the influence of energy drinks on the performance of the...

Electrophoresis gel with annotation

Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA. A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black
band appears in a particular lane that base is present. By reading off the order of bands across the four lanes the...

Automated DNA sequencing output

The output from an automated DNA sequencing robot used by the Human Genome Project to determine the complete human DNA sequence. Each peak shows the presence of a particular base. The sequence of bases in a given stretch of DNA can therefore be read from the order of the peaks along the trace. The sequences of...

GENIE jumping genes

The aim of this activity is for students to use tiddlywinks to represent sections of jumping genes, which they then flick onto a poster which is representative of a section of the human genome. Where their "gene" lands either will or will not disrupt the gene and may then cause disease. An accompanying PowerPoint...
