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. Activity Life in a pond (demo)
