This experiment provides a quick and eye-catching way to teach about the vascular tissue in plants and the structure of plant stems. It provides students with the opportunity to develop (and demonstrate) their scientific drawing skills as well as their use of a light microscope and eye-piece graticule.

The...

This updated version of the SAPS algal balls resource is designed to support the use of practicals across 2015 A-level biology specifications.

Students measure the rate of photosynthesis in comparison to the rate of respiration. Because of this, it is possible to determine the light intensity at which the...

Produced by Science & Plants for Schools (SAPS), this investigation enables students to investigate the process of mitosis in a growing root tip. The mitotic index is the fraction of cells in a microscope field which contain condensed chromosomes.

In this activity students prepare and stain root tips....

This video introduces a reliable technique to demonstrate tissue culture and totipotency, and shows how best to use this protocol with your students.

Unlike animal cells, many plant cells are totipotent, meaning that...

Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effect of competitive and non-competitive inhibitors on the enzyme beta-galactosidase.

The chemical ONPG (o-nitrophenyl beta-D-galactopyranoside) is degraded by the enzyme beta-galactosidase. The product is...

These eighteen assignments and a teachers' guide, from the Association for Science Education (ASE) aim to encourage non-scientists to embrace a little science. The aim is to increase student's skills whilst quashing a few "science is boring" stereotypes. All assignments have been written to cover a variety of non-...

This resource provides background information for students about the structure of DNA, DNA replication, genetic engineering, cloning, genetic testing and DNA fingerprinting.

The activities for students include a practical activity where students extract their own DNA from cheek epithelial cells or plant...

This resource is designed to meet the specifications for the A-level practical endorsement in England (CPAC). However, it will make a valuable guide to dissection and scientific drawing of a flower for those following a variety of different specifications.

The ability to accurately observe, dissect and...

Produced by Science & Plants for Schools (SAPS), in this investigation, students look at the concentration of glucose in isotonic sports drinks. This enables students to see if the drinks are, in fact, isotonic with the blood.

In this investigation, students first produce a standard curve by testing...

Produced by Science & Plants for Schools (SAPS), this activity enables students to look at the gel electrophoresis of DNA treated with restriction enzymes. It will help to develop a knowledge and understanding of the cutting of DNA with restriction enzymes.

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An enjoyable and thought-provoking introduction to the topic of sexual reproduction in plants. Students observe in real time the growth of a pollen tube, over the course of a lesson. When a pollen...
