Here are few apps that you might consider using with your students – i am providing web links but all are available as apps at istore or google play
Agents of Nature – http://agentsofnature.com/teacherslanding – discover species of plants and animals that live in Calgary parks
Project Noah – http://www.projectnoah.org/ Engage students in documenting local wildlife by uploading photos via mobile phone or tablet as part of a classroom or school-wide mission. A global community can help I.D. their “spottings” which in turn help scientists uncover and track wildlife populations.
Journey North – https://www.learner.org/jnorth/ – Your students can be citizen scientists, tracking wildlife migrations and seasonal changes in the environment around them. They can report their sightings from the field, view maps, take pictures and leave comments.
Weather Bug – http://weather.ca.weatherbug.com/ – Give your students access to the world’s largest network of real-time weather sensors for forecasts, alerts and more. Students can check weather conditions before heading out for field study or collect weather data over time and study how it impacts the local environment.
Creek Watch – http://www.scientificamerican.com/citizen-science/creek-watch/ – Be stewards of your local watershed by using this app to snap photos of a local waterway and report how much water or trash there is. The app aggregates the data and shares it with local water agencies to help them track pollution and water resources.
Whats Invasive – http://www.whatsinvasive.org/? – Help scientists locate invasive species by making geo-tagged observations and taking photos in their natural areas. The information students collect can help stop the spread of invasive species which destroy native habitats.
Natures Notebook – https://itunes.apple.com/us/app/natures-notebook/id508465801?mt=8 – Observe and record plant and animal lifecycle events (also known as phenology), such as flowering and bird migration. The observations also help scientists understand how species respond to environmental changes.
iNaturalist – https://itunes.apple.com/ca/app/inaturalist/id421397028?mt=8 – Record nature observations and share them with the online community of naturalists. Students can also keep a log of the wildlife they discover and the biodiversity they experience while being outdoors.
Leafsnap – https://itunes.apple.com/ca/app/leafsnap/id430649829?mt=8 – Leafsnap is the first in a series of electronic field guides being developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution. This free mobile app uses visual recognition software to help identify tree species from photographs of their leaves.
