Students overlay USGS topographic maps into Google Earth’s satellite imagery. By analyzing Denali, a mountain in Alaska, they discover how to use map scales as ratios to navigate maps, and use rates to make sense of contour lines and elevation changes in an integrated GIS software program. Students also problem solve to find potential pathways up a mountain by calculating gradients.

The U.S. Census Bureau has given detailed information on Health Insurance. Each category is provided via a link. Definitions are included within these categories.

A listing of all sorts of available reports on bismuth. Great resources for students at many levels.

You will find this list of questions interesting and amusing. "Things like, "Is salt water used for anything in the U.S.?," and How can we have a 100-year flood two years in a row?", are found on this this. Click Home to access the site in Spanish.

A collection of articles, games, printouts, facts, science fair ideas, and links through which students learn about the history and science of earthquakes and also explore what it takes to be an "earthquake scientist."

This activity follows on from Charting Success and encourages students to consider and analyse representations of data from the world of sport, to make sense of the stories they tell, and to analyse whether the right representation has been chosen for the purpose. It is aimed at secondary students (Key Stages 3 and 4).

Sports statisticians, trainers and competitors create graphs, charts and diagrams to help them to analyse performance, inform training programmes or improve motivation. This activity encourages students to consider and analyse representations of data from a number of sports, and to discuss whether the right representation has been chosen for the purpose. It is aimed at secondary students (Key Stages 3 and 4).

Can you work out which Olympics athletics event each anonymised graph of Olympic records data represents? This activity, aimed at Key Stage 3 (age 11-14), gives students the opportunity to make sense of graphical data and challenges them to apply their own knowledge about athletics to explain and interpret key features of the graphs.

The CyberSquad searches for HackerŒë_í_Œ_ castle based on a survey of where town residents have last seen him in this video from Cyberchase.

Relative frequency is how often something happens divided by all the outcomes. Watch this tutorial to learn all the steps needed to find the relative frequency. [3:25]

A line-of-fit is a line that summarizes the trend in a set of data. In this tutorial, you'll see how to graph data on a coordinate plane and draw a line-of-fit for that data. [1:12]

This tutorial takes you through the steps of creating a scatter plot, drawing a line-of-fit, and determining if there is any correlation. [1:56]

Frequency tables tells you how often something occurs in a set of data. Watch this video for examples of frequency tables. [6:44]

Watch this tutorial to take a look at the scatter plot which is useful for graphically showing a bunch of data. [1:17]

Prepared with pre-algebra or algebra 1 classes in mind, this module leads students through the process of graphing data and finding a line of best fit while exploring the characteristics of linear equations in algebraic and graphic formats. Then, these topics are connected to real-world experiences in which people use linear functions. During the module, students use these scientific concepts to solve the following hypothetical challenge: You are a new researcher in a lab, and your boss has just given you your first task to analyze a set of data. It being your first assignment, you ask an undergraduate student working in your lab to help you figure it out. She responds that you must determine what the data represents and then find an equation that models the data. You believe that you will be able to determine what the data represents on your own, but you ask for further help modeling the data. In response, she says she is not completely sure how to do it, but gives a list of equations that may fit the data. This module is built around the legacy cycle, a format that incorporates educational research feindings on how people best learn.

Students collect a large set of data (approximately 60 sets) of individual student’s water use and learn how to use spreadsheets to graph the data and find mean, median, mode, and range. They compared their findings to the national average of water use per person per day and use it to evaluate how much water a municipality would need in the event of a recovery from a water shutdown. This analysis activity introduces students to the concept of central tendencies and how to use spreadsheets to find them.

This article assembles free resources from the Weather and Climate issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

This WebMathsite provides an interactive number line "solver." Content includes helpful hint and a full explanation of the mathematical solution.

SQL is useful for creating and querying relational databases. Learn how to use SQL with this interactive course! [2:04]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
