Ten Great Tech Tools for Social Studies Lessons
Over the last decade I've written about a lot of excellent resources for social studies lessons. Over time some of those tools have faded away and others have moved to the forefront of my top recommendations. Here's my current list of ten top tools for social studies lessons. Timeline JS Timeline projects as as old as history classes themselves. It used to be that timelines were only made on paper. Today, students can build timelines that include videos, audio recordings, pictures, and interactive maps.
World’s Most Dangerous Countries Revealed, And It May Change Your Travel Plans
Just like last year, International SOS and Control Risks have released a map that shows just how tourist-friendly all countries are, and it’s worth looking at if you’re planning a trip for 2018 to a place you’ve never been before. After all, we all like coming back from a holiday with all of our limbs and other valuables. Show Full Text
Mapping the Real World
We all think we know how the world looks. But do our maps of the world always reflect what is most important? Much has been said, for instance, about the astonishing economic growth witnessed by China over the past few decades. China’s geographical map in Figure 1 (Left), however, tells us nothing about the extent of the Gross Domestic Product (GDP) growth in different parts of the country. What if we could produce more visually informative maps? As it turns out, we can.
8 Options for Making Digital Maps
In yesterday's post about English Heritage's Map of Myth, Legend, and Folklore I included a mention of using StoryMap JS to create interactive maps. That prompted a response from Cindy Rudy who suggested the idea of using Thinglink or Google Earth to make similar maps of myths, legends, and folklore. That was my inspiration for this run-down of eight options for making digital maps.

AuthaGraph World Map Antarctica was found in 1820 and the first man reaches the North Pole in 1909. In the 20th century the world tended to be framed by the East-West relations and the North-South problem.
Population Estimation Service » Gridded Population of the World (GPW), v4
Population Estimation Service The Population Estimation Service is a Web-based service for estimating population totals and related statistics within a user-defined region. It enables users of a wide variety of map clients and tools to quickly obtain estimates of the number of people residing in specific areas without having to download and analyze large amounts of spatial data. The pes-v2 service accepts polygons that define areas of interest, and a string which selects a year from the set of 2000, 2005, 2010, 2015 or 2020 then returns population totals, land area, quality measures, and basic parametric statistics for the requested polygons based on data from SEDAC's Gridded Population of the World version 4 (GPWv4) dataset. If no year is specified the default is to provide results for the year 2015.
What Causes Ocean Currents?
The systems of ocean surface currents and deep water currents are, as expected, connected, but the locations of the physical connections are limited to three areas (one per main ocean), and are all on the Northern Hemisphere. The downwelling occurs on the Northern Atlantic, while the upwelling occurs on the Northern Pacific and the Northern Indian Ocean, as shown on the side map. The extents of the continental shelf block, or at least seriously limit, the movement of the ocean currents. To see a 3D view of the Conveyor Belt enlarge the diagram below. 1.
A Spy, a Map, and the Quest for Power in 16th-Century Europe
This story appears in the March/April 2017 issue of National Geographic History magazine. Knowledge is power—and no knowledge was more assiduously coveted by European nations in the early 16th century than the information recorded on nautical maps. Coastlines, harbors, rivers, resources: Details about these features could give a nation a distinct advantage in trying to stake a claim to new lands. The “Cantino Planisphere,” completed in 1502, is the second known chart to have depicted the New World. It included unpublished information on Portuguese trade routes and the ongoing discovery of the coastline of modern-day Brazil. At a time when knowledge of new territories lent expanding nations great strategic and commercial superiority, such maps were guarded as state secrets.
Color wheels – Infographics for the People
Above,“Farbkreis” from “The Art of Color” (1961), by Johannes Itten, a Swiss painter and theorist who taught at the Bauhaus. This 12-hue circle is made up of three primary, three secondary and six tertiary colors. “The Color Star” (1986) has eight disks with cut-outs that can be rotated over Itten’s star to compare colors. Now we have so many excellent digital color aids, like Adobe Color: But… I still remember art theory classes way back in art college. They were not that easy (we used to moan about them), but in retrospect, it was important knowledge.
You decide Australia's population, we'll show you how it looks
Australia's population has more than quadrupled in the past century, with the number of people tipped to reach 25 million this year. If current trends continue the population will top 40 million within 40 years. Some say Australia should have stopped growing decades ago. Others point out Australia is a wealthy country with plenty of space to welcome more. This is your chance to decide how big (or small) you think Australia should be. The chart below shows 24 potential paths for Australia's future population, based on the latest projections from the Australian Bureau of Statistics.
ISOTYPE Book: Florence, Only An Ocean Between
The book Only An Ocean Between by Lella Secor Florence contains some of the most iconic ISOTYPE charts. It was published in 1943, as part of a small series called America and Britain. Unlike some other ISOTYPE books, this one (and the other two in the series) advertise the charts right on the cover.
