A few days ago, the World Meteorological Organization (WMO) issued a press release announcing that globally averaged Carbon Dioxide (CO2) levels in the atmosphere have reached the symbolic and significant milestone of 400 parts per million (ppm) for the entire year. The UN agency made a bold prediction, painted a bleak picture if the trend continues, and declared that this marks the start of a new era of climate reality.
From the WMO press release:
“CO2 levels had previously reached the 400 ppm barrier for certain months of the year and in certain locations but never before on a global average basis for the entire year. The longest-established greenhouse gas monitoring station at Mauna Loa, Hawaii, predicts that CO2 concentrations will stay above 400 ppm for the whole of 2016 and not dip below that level for many generations.”
Next Generation Science Standards & Enabling Students to Explore CO2 Data
Did you know that the historical Atmospheric Carbon Dioxide data from the Mauna Loa Observatory is in the Tuva Datasets Library?
Tuva’s Atmospheric Carbon Dioxide (1958-2015) (Tuva Premium subscribers only) dataset enables your students to wear the hat of a meteorologist. Students can easily explore, visualize, analyze, and model the atmospheric Carbon Dioxide data from the Mauna Loa observatory, just like the meteorologists at WMO.
They can explore critical questions such as:
a. How has the globally averaged CO2 levels increased over the last 50 years?
b. When did the average CO2 level first past the 400ppm threshold?
c. How does the average CO2 levels vary by seasons, and why?
d. If this increasing trend continues, what will be the global average CO2 levels in 2050?
Cultivating students’ scientific habits of mind, building their capability to engage in scientific inquiry, and engaging them in practices that reflect those of scientists, researchers, and engineers is one of the primary goals of the Next Generation Science Standards.
At this watershed moment in climate science and human history, Tuva enables you to realize this vision with your students.
Once you have chosen your dataset, you can now review it thoroughly before uploading it to Tuva.
The enhanced review step now allows you to edit and update various aspects of your dataset, including:
Remember – you can always make changes to the attributes from the Case Card if you have already uploaded the dataset to Tuva.
Here is a scenario: You have imported a dataset from Google Spreadsheet into your repository on Tuva.
Screenshot: Tuva Dataset titled “Census at School – Clean Data” has been imported from Google Spreadsheet
You make changes to your Google Spreadsheet, removing an attribute or adding 10 more rows of data. Till now, it was difficult to easily update and reflect these changes on your Tuva dataset.
Wouldn’t it be nice to be able to refresh your dataset directly from Tuva without have to import your Google Spreadsheet again?
Introducing Refresh
The Refresh feature allows you to easily update your Tuva Dataset so that any changes you make to your Google Spreadsheet will automatically be reflected in your dataset on Tuva.
Screenshot: Refresh button on Tuva Dataset page
Please note that the Refresh feature is only available for Tuva Datasets that you have imported from Google Spreadsheets. It is not available if you have imported the dataset from your computer.
Checkout the Refresh feature, and please feel free to share your comments and feedback on Tuva Discussions.
Tuva is excited to participate in a session alongside WestEd and NSVF Ignite on EdTech Research that Empowers Educators and Entrepreneurs at the New Schools Summit in San Francisco on May 11, 2016.
Other participant teams in this session include: Distinctive Schools, Rocketship Education, Lexia Learning, Proving Ground Project at Harvard Center for Education Policy Research, and MIND Research Institute.
It promises to be a fantastic session, exploring the paramount topic of how rigorous education research can inform the design and development of tools and products to drive more effective teaching and learning in the classroom.
Are you planning to be at the New Schools Summit? If yes, please join us at the session.
