Teen Tech Tip of the Week #5: Trendalyzing 
Welcome back to the blog for a more challenging week. This week we are looking at some web applications that perform trend analysis.

This week's topic is an extremely useful tool that can take your research assignment to the next level. Trend analysis is a form of critical thinking that investigates the connections between patterns occurring simultaneously. For example, it would be interesting to see the correlation between life expectancy and income per person for different nations over time. Seeing correlations like this can lead you develop new and interesting topics for research papers. To do this, I list links for three different, but very powerful online applications.

Gapminder World Owned by Google, Gapminder World graphically presents a large amount of historical data for the development of countries around the world. Topics include population, economy, society, environment, health and more. Change the variables on the x- and y-axes to view a new data set. Click the play button below the graph to watch changes over time. Be sure to check out the Graph Menu for preset graphs.

EarthPulse National Geographic's vital statistic program allows you to compare side-by-side gradient maps of various topics including population density, consumer demand and natural resources. Be sure to check out the essay section.

Global Conservation Maps Powered by Google Fusion Tables, the Nature Conservancy's natural resource maps allows you to compare conservation maps around the globe. Check out the Maps link in the ribbon for featured maps.

This week's topic is meant to be a little more challenging. Check back with us next week for a bit of fun.
