## United States History Map

Become a geography whiz as you learn how the United States was settled. Discover how the continent was irrevocably changed by European colonization, the events that caused the wholesale displacement and decimation of the land's original inhabitants, and how the 50 states came to be formed.

## Units and Prefixes

Explore some common units and prefixes in the metric system. Then decide which metric units you would use to measure several displayed objects.

## US History Map Assessment: Test Your Skills

Test how much you know about major U.S geographic features, Indian tribes, states and regions, European colonists and territorial expansion. View your correct and incorrect answers, and print out your assessment.

## Variation in Estimates

A computer can perform random sampling and estimation faster than you can. Use the computer to help you estimate a penguin population from computer-selected random samples.

## Virtual Particle Lab: Compressibility of Air

Explore the particle model of matter. Run the simulations and see if you can predict the results.

## Virtual Particle Lab: Dissolving

Explore what happens when one substance dissolves into another. Run the simulations and see if you can predict the results.

## Volcanoes

Today, there are many active volcanoes worldwide. Is there anything we can do to predict how and when they will erupt?

## Volume Symbols

Study the names and abbreviations of volume units in both the metric and British systems. Then play a game to see how well you remember them.

## Weather

Try your hand at tornado chasing and discover how wind chill works.

Political parties have platforms that describe their principles and issue stances in areas such as taxes, education and immigration. Answer the questions to see which party (Democratic, Republican, Green and Libertarian) is your best fit.

## What's Inside the Earth?

What’s inside the earth? Examine the earth’s distinct layers (crust, mantle and core) and find out.

## Where Is the Player?

Examine how multiple light sources produce shadows of differing darkness and length. Move a player (with four light sources) around the field until your image matches the five other images on the page so you can identify where the player is on the field.

## Where Should You Build?

Plans are underway for three large building projects near Milehigh Volcano. You must examine soil samples at each site, decide whether or not it’s safe to build and then go to the press conference to report your findings

## Which famous cathedral collapsed?

After looking at four photos of cathedrals of the Middle Ages, try to choose which one fell and see if you can determine, from the pictures, why it might have collapsed.

## Which One of These Elements Doesn't Belong?

Use your knowledge of groups and periods on the Periodic Table. When you are presented with three elements, pick the one that doesn’t belong.

## Who Says We're Alike?

You are working for candidate Fletcher. Read his political profile, view the demographic profile of the city, and decide which random sample increment to use when you conduct your first telephone poll of Republican women.

## Whooping Cranes

Track the migration of whooping cranes, once on the verge of extinction. Follow new crane chicks from their hatching to the day they complete their first fall migration at 5 to 6 months of age.

## Why did Copan Collapse?

What happened to bring about the collapse of Copán, once a thriving center of Maya civilization? Study evidence of its monuments, soil and plants, homes, farms and archaeological remains and use your Copan journal to record important clues.

## Wind Chill

Why do windy winter days seem so bitterly cold? Calculate the wind chill factor and find out.

## Working with the Mean Absolute Deviation (MAD)

The concept of the arithmetic mean and deviation from the mean can be graphically representated as a line plot. You will create a line plot to represent specified allocations of coins.
