Investigating enzymes: inhibition of catechol oxidase in bananas
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this practical, student investigate how lead inhibits catechol oxidase, an enzyme which is easily extracted from a banana and which is responsible for turning fruit brown. Measuring the intensity...
Investigating enzymes: microscale investigations with catalase
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A simple yet accurate protocol looking at the results of the enzyme catalase. Catalase is a widespread enzyme, protecting the cell from toxic effects of hydrogen peroxide by catalysing its...
Investigating enzymes: phosphatase enzymes in plants
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A standard protocol which is used to extract phosphatase enzymes from plants, including a method to calculate the rate of reaction. Phosphatases are enzymes widespread in plants easily extracted from...
Investigating Factors Affecting Photosynthesis Using Leaf Discs
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An enjoyable and reliable practical activity allowing students to compare factors affecting photosynthesis. Possible investigations could include the rate of photosynthesis in sun and shade plants,...
Investigating Fertilisers: the Effects of Minerals on Plant Growth
In this practical, students investigate the effects of different levels of minerals (nitrates, phosphates and potassium) on the growth of radishes. Students sow radish seed in ‘soil’ containing different levels of 3 minerals - nitrates, phosphates and potassium. These minerals are present inside N:P:K fertiliser...
Investigating flower structure and function in primulas
This resource is designed to meet the specifications for the A-level practical endorsement in England (CPAC). However, given its focus on adaptation and evolution, it will make a valuable resource for those following a variety of different specifications, such as the Advanced Higher Biology Organisms and Evolution...
Investigating Gravitropism Using Seedlings
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An intriguing way to demonstrate gravitropism in action over the course of a lesson. Using black film canisters, a freshly cut seedling stalk (hypocotyl...
Investigating How Plants Use Colour to Attract Pollinators
In this investigation, students look at the way in which flowering plants use colour to attract pollinators, and particularly bees. They carry out a variety of short practicals and research activities, designed to allow students to gain a deeper understanding of adaptation, evolution and biophysics – understanding...
Investigating if Plants Grow Better with Fertiliser
This resource, aimed at primary level, helps to develop an understanding of what plants need to grow well. It provides an opportunity to plan and carry out a fair test looking at the effect of fertilizer on growing radishes. It includes detailed notes on setting up and...
Investigating osmosis: measuring the water potential of a potato cell
Understanding the osmotic potential of plant cells is a key part of understanding...
