Data Recorders for your Research Questions

Classroom Experiments Wanted
Do you ever wonder what is going on under ground in the tulip garden? Do you have unanswered research questions like these from Sara Hepner, one of our Alaska Journey North gardeners:

“Is there a specific temp requirement for bulbs to sprout? Does the soil need to be at or above that temp for a certain number of days prior to sprouting? Does the rate of leaf growth correspond to the soil temperature?”

Many classrooms monitor outdoor temperatures throughout the winter and spring seasons. Temperature recording equipment can have a high mortality rate in a school yard setting. Here is your chance to try some new temperature monitoring technology.

Data recorders come in all sizes and shapes

A temperature probe combined with a data recorder can give you authentic data for your experimental plots and experiments. There are so many neat ways these could be used with your studies; look at some things already being tested:

  • temperature of the soil each month.
  • changes in the bulbs compared to the soil temperature.
  • temperature of the soil compared to the air temperature.
  • temperature at different depths.
  • microclimate differences compared with air and soil temps
  • temperatures of bare ground compared with naturally insulated ground
  • soil temperatures under various amounts of insulation cover

Join other classrooms to develop your own experiments!
Basically, you and students come up with an experimental plan and apply for the free use of temperature data recorders. Get your "loaner" data recorder for a 2-month use.
