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...

With just a few materials, building a paper model of the International Space Station (ISS) can become a class project. This publication contains a brief overview of the ISS, its parts, the science that occurs on board, instructions, and extension fact sheets. Learn about the ISS, explore fun facts, simulate...

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 resource from Science & Plants for Schools (SAPS) describes the work of Charles Darwin on carnivorous plants to determine what causes the leaves to curl up when stimulated.

Darwin’s experiments are very easy...

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...

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...

This is a modelling activity where students use sampling techniques to determine the distribution and abundance of organisms in a simulated habitat. Students will simulate the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species. 

Curriculum links include: ...

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

In this resource, produced by OPAL (Open Air Laboratories), children take part in a pond dipping session and then try to identify the different animals they find. A second activity looks at water quality and how the presence of certain species can indicate how clean the water is.

Designed for use in the...

This resource, produced by OPAL (Open Air Laboratories), aims to develop an awareness that there are different kinds of invertebrates in the environment which have different habitat requirements. It links to the topics of minibeasts, habitats and classification and is designed for use outside the classroom when...
