Investigations in post-16 biology
These reliable practicals from SAPs allow students to practice a range of skills, such as microscopy skills, serial dilutions, plotting and using standard curves and developing mathematical skills. These investigations were designed for students following a Scottish Highers course but they are equally useful for other post-16 courses in biology. Some could even be adapted for secondary students of a younger age.
The investigations include:
- Investigating the hormone auxin (IAA), a plant growth regulator
- Fruit juice production and enzyme recovery
- What determines the number of spines on a holly leaf?
- The effect of phosphate on the enzyme phosphatase
- Stomatal opening and closing in commelina communis
- The response of leaf discs to green light
- The effects of IAA on root growth
- Competitive and non-competitive enzyme inhibition
- Estimating the glucose concentration of a solution
- The effects of mineral concentrations on plant growth
- Investigating potato cyst nematodes
- Examining mycorrhizae
- Protoplast isolation
- Investigation enzymes: microscale investigations with catalase
- Investigating enzymes: inhibition of catechol oxidase in bananas
- Investigating enzymes: phosphatase enzymes in plants
- Investigations into eutrophication
This protocol allows students to investigate the effects of the hormone auxin (Indole Acetic Acid or IAA) as a plant growth regulator. The investigations give opportunities to look at auxiliary bud development, root development, and leaf abscission in Coleus. The method is suitable for independent investigations by...
Produced by Science & Plants for Schools (SAPS), in this investigation, students look at the effectiveness of enzymes used in the commercial production of fruit juices.
Fruit juice companies use enzymes to break down the cells walls within the fruits and release the liquids and the sugars which make up...
Produced by Science & Plants for Schools (SAPS), this activity enables students to:
• develop knowledge and understanding of structural defence mechanisms in plants
• develop problem solving skills
• demonstrate the processing of information and use of calculations
Produced by Science & Plants for Schools (SAPS), this investigation looks at end-product inhibition of the enzyme phosphatase.
The investigation is designed for students following a Scottish Highers course but it is equally useful for other post-16 courses in biology.
This investigation involves...
