Create a Plant
Create your own flowering plant collage using selected materials. Once created label the different parts and discuss their role in a plant. Further ideas can be found in the full resource Parts...
Designing a Seed
Design and make a seed from a newly discovered plant using junk materials.This activity provides an opportunity for creative thinking around the topic of germination and seed dispersal. It also supports the development of literacy and presentation skills. Further ideas...
Determining Doubling Time
As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth. Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a colorimeter...
Determining Dry Weight
This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.
The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...
Produced by Science & Plants for Schools (SAPS), these activities look at career opportunities in plant biology, as well as useful classroom activities and practical investigations. The range of careers and activities covered include:
...Dissection and scientific drawing
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...
Dissection and scientific drawing
The ability to accurately observe, dissect and record an organism is a key skill for biology students. Many students are intimidated by the idea of making a scientific drawing, and struggle to develop their skills in this area.
This resource is designed to meet the specifications for the A-level...
Do plants need soil to grow?
This resource provides a set of videos and a practical investigation aimed at supporting working scientifically in the classroom and relating science to real world experiences. In the first video Professor Brian Cox joins a teacher to find out how to set up and run an investigation to find out if plants need soil...
Doubling and Dabbling in Duckweed
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...
Enzyme Activity in Fruits and Vegetables
Produced by Science & Plants for Schools (SAPS), these materials give a range of suggested activities that investigate enzyme activity in ripening fruit. These include:
• the changes in enzyme activity during ripening and storage
• the activity of the same...
