Seeing Without Eyes - Plants, Photoreceptors and Gene Expression
One of a series of articles for post-16 students published by Science and Plants for Schools (SAPS). Plants monitor the intensity, direction, colour and duration of the light they receive and use this information to adapt their growth and metabolism to their particular environment. Most plant responses to light...
Staining a Root Tip and Calculating Its Mitotic Index
In this practical activity students stain root tips and examine them for signs of cells dividing by mitosis. Students can either compare two different sources of root tip or two different stains. The mitotic index is the fraction of cells in a microscope field which contain condensed chromosomes. This index can be...
STEM Careers Profiles to Inspire Your Students
Designed to raise awareness of a greater range of STEM careers for post-16 students, t...
Stomatal opening and closing in commelina communis
Produced by Science & Plants for Schools (SAPS), this investigation looks at stomatal opening and closing in Commelina communis (Asiatic dayflower). This is achieved by varying the turgor of the guard cells by bathing lower epidermal peels in solutions of different osmotic strengths. Changes in guard cell...
Stresses and Strains in Plants
From Science & Plants for Schools (SAPS), these practical activities allow students to investigate how woody and herbaceous plants support their shoots, branches, flowers and fruits and shed them at the appropriate time.
A number of investigations are suggested that can be adapted for students over a...
Sucrose and the Growth of Root Explants
From Science & Plants for Schools (SAPS), this practical activity was developed for Scottish Highers specifications, but the protocol can equally well be used for other specifications.
Students sterilise seeds of...
Sweet or Sour?
Produced by Science & Plants for Schools (SAPS), this investigation looks at the taste of different fruits and vegetables. Domesticated fruits and vegetables have all been selectively bred so that they contain a particularly attractive taste for humans.
...Symbols and Units: a Survival Guide *suitable for home teaching*
From Science & Plants for Schools (SAPS), this guide explains the rules for using symbols and units which students will meet in their science courses and reminds of the importance of using them, and writing them, correctly.
The guide contains six sections:
1. SI base units
2. Derived units...
