The following activity was part of a 3-day science activity. Preceding this were learning activities to do with sustainable energy production. This time the children were given data loggers (sensors) that measured temperature, light (different kinds), CO2 or voltage. The children hd to use apps to extract the information and log it on their phones or computers. The task was to investigate how to use these school owned data loggers. The children were asked to find out what the software could do and set up an investigation on sustainable energy.
One group tried to investigate the influence of temperature on conductivity of different materials to reduce the loss of energy due to heating.
Another group tried to investigate how much CO2 is absorbed through photosynthesis.
A third group measured the velocity of wind and change of wind speed over time.
Given that they had freedom to explore the sensors and what the software could show them, the children were motivated and curious to explore things and ask their own questions. They felt competent to try things out, evaluate ideas and practice communicating the things they experienced and observed. The technology they were given forced them to think about what other technology they may require to set up a working experiment. Lots of trial and error and excitement!
