Introducing the Second Tuva Science Collection — Atmosphere

“Have lights when other men are blind

As pigs are said to see the wind”

Aside from Ralph Waldo Emerson’s claim (paraphrasing William Butler), of all Earth systems, the atmosphere can be one of the hardest for (non- pig) students to perceive.

Although we breathe in atmosphere every minute, its chemistry, layers, air masses, and patterns of movement occur at large scales and are often invisible.

We can feel the wind, but how can we discern its large-scale geographical and temporal patterns? Through data, of course!

Following up from the release of our first Tuva Science Collection on Earth in Space,  today we are excited to introduce Tuva’s second science collection – Atmosphere.

The Atmosphere Collection includes datasets and activities that explore differences among vertical layers in the atmosphere, geographic variability in atmospheric pollutants, and temporal changes in components of the atmosphere such as the stratospheric ozone layer.

Some of the activities also explore weather and climate data to make sense of how air masses move.

Key ideas supported by datasets and activities in Tuva’s Atmosphere Collection include:

  • The size of the Antarctic ozone hole changes seasonally and is correlated with atmospheric concentrations of CFCs.
  • Atmospheric concentrations of CO2 and other pollutants have increased during recent decades, as has human population.
  • Relationships between different atmospheric parameters can be modeled and predicted mathematically.
  • Air masses can transport pollutants from source areas to distant non-source areas.  
  • Human actions to mitigate air pollution can improve air quality.

The activities support NGSS performance expectations, such as exploring evidence for how motions and interactions of air masses result in changes in weather conditions (MS-ESS2-5), or analyzing geoscience data to forecast of the rate of change in the ozone hole (HS-ESS3-5).

These activities also support a number of CCSS-Math standards such as modeling relationships with linear equations.

Don’t forget to give your students opportunity to explore data on their own to make their own discoveries. Help your students learn to “see the wind” — through data!

The Earth in Space and Atmosphere collections are available for Tuva Premium Subscribers.

Introducing the first Tuva Science Collection — Earth in Space

earth-rising

Here a star, and there a star,

Some lose their way.

Here a mist, and there a mist,

Afterwards — day!

Few have conveyed the beauty of dawn with more inspiration than Emily Dickinson. As teachers of Earth science, we aspire to convey to students appreciation and understanding of what it means to be a planet moving through space and how our position and movement in space predictably affects our everyday experience of, well — day!

The magnitude of spatial and temporal scale differences covered by the topic of “Earth in Space” makes it challenging to find datasets about stars, planets, Sun and Moon, orbits,  seasons, tides, and day-lengths that are of a scope that students can explore to find meaning and discover patterns and relationships.

At Tuva, we are gathering datasets into collections by topic to help you quickly find data and activities that support a unit you are teaching. Our first Tuva Science Collection is Earth in Space.

Tuva’s Earth in Space collection provides opportunities for students to analyze and interpret data and model systems (see NGSS ESS1.A and ESS1.B) to support understanding of key ideas such as:

  • Stars range in size, type, and distance from our Solar System.
  • Planets have different properties (density, gravitational pull, orbital period, temperature…)
  • Seasons occur at opposite times of year in northern and southern hemispheres.
  • The timing of tide cycles can be explained (and predicted) by the phase (and position) of the Moon.
  • How much day length changes through the year depends on latitude.

Each dataset has at least one activity, and you can add or adapt activities to fit your teaching goals.

Help your students discover and appreciate the music of the spheres — through data!

We will be adding many other science collections in coming weeks and months.  If there is a collection you are especially interested in, please let us know via Tuva Support or share with the community on Tuva Discussions.

Enhancements to the Review Step While Uploading Your Dataset to Tuva.

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:

  1. Updating the Title as well as the Source of the dataset.
  2. Updating the Privacy Settings of the dataset.
    1. The default privacy setting is “Only Me”, but you can update the setting to “Anyone with Link” if you want to share the dataset with others. 
  3. Updating the Name and Description of the attributes of the dataset. 
  4. Updating the Type of the attribute, allowing you to choose between Categorical or various Numerical formats.
  5. Updating the Order of values for an attribute, choosing between Ascending or Descending order.

Remember – you can always make changes to the attributes from the Case Card if you have already uploaded the dataset to Tuva.

Refreshing your Tuva Datasets from Google Spreadsheets

Here is a scenario: You have imported a dataset from Google Spreadsheet into your repository on Tuva.

Dataset_Upload

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.

Refresh_Dataset

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 in an EdTech Research Session at the New Schools Summit

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.
