In this activity students conduct a video measurement of the growth of the root and stem of a plant after germination. The analyse the growth curve of the plant and couple the growth speed to available energy.
Activity Graphs of plant growth
Plant physiology
In this activity students investigate whether plants also respire. Most people know that animals respire but what about plants? By making use of germinating seeds, and a CO2 sensor, the respiration of plants seeds can be measured.
Activity Respiration of plant seeds (demo)
In this activity students examine the photosynthesis. Using an O2 sensor to measure the rate of photosynthesis at different light intensity. How much disadvantage has a plant in the shade anyway?
Activity Photosynthesis (light intensity) (demo)
In this activity students study life in a pond. From behind the computer they use an existing model to investigate the impact of plants, animals and light on the oxygen concentration in a pond. A fun activity in which respiration, photosynthesis and the influence of light are brought together.
