Scale Model of the Earth
In this activity, students gain an understanding of the layers of the Earth by designing and building a clay model.
Mercalli Scale Illustrated
In this activity, students will learn about the Mercalli Scale for rating earthquakes. Also, students will make a booklet with drawings that represent each rating of the scale.
Seismology in the Classroom
Students learn about seismology by using a sample seismograph constructed out of common classroom materials. The seismograph creates a seismogram based on vibrations caused by moving a ruler. The students work in groups to represent an engineering firm that must analyze the seismograph for how it works and how to read the seismogram it creates.
Earthquake in the Classroom
Students will learn how engineers construct buildings to withstand damage from earthquakes by building their own structure with toothpicks and marshmallows. Students will test how earthquake-proof their buildings are by testing them on an earthquake simulated in a pan of Jell-O®.
Where Am I: Navigation and Satellites
How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people lost in their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also,
Getting to the Point
In this lesson, students learn how to determine location by triangulation. We describe the process of triangulation and practice finding your location on a worksheet, in the classroom, and outdoors.
The Boxes Go Mobile
To display the results from the previous activity, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.
Heredity Mix ’n Match
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple’s offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the “couples” in
Map that Habitat
Historically, sea floor mapping occurred with a more simple data collection method: soundings. Soundings are taken by dropping a weight with a pre-measured rope off the side of the boat and noting the measurement on the rope when the weight hits the bottom. This activity will replicate the creation of sea floor bathymetry by taking a simplified form of soundings in the classroom.
Rocks, Rocks, Rocks
Student teams will test rocks to identify and record rock properties such as luster, hardness, color, etc., and classify rocks as igneous, metamorphic and sedimentary. They will complete a worksheet table with all of their rock properties, and then answer some worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.
Testing the Caverns - Optional
This activity provides a fun, activity-based closure to the Asteroid Impact unit. Students build model caverns using paper mache or clay and bury them in a tray of sand. Next, they test the models by dropping balls onto them to simulate an asteroid hitting the earth. By molding paper mache around a balloon to form a dome, or around a small cardboard box to form a rectangular structure, students will be able to build their caverns.
What's the Problem?
Lesson 1, Activity 1 introduces the Asteroid Impact unit. Students will read the President’s memo to receive their ‘marching orders’. Student teams are then formed and are given the student packet that includes worksheets and maps. Each team should become familiar with the maps and complete Worksheet One as a group.

Gary Hirshberg: Make Money and Save the World Environmental activist and businessperson Gary Hirshberg calls on individuals to realize their power to effect change in the marketplace — "the power of one" — while proving that environmental commitment makes for a healthier planet and a healthier bottom line. Hirshberg, president and "CE-Yo" of Stonyfield Farm, Inc. — the world's largest organic yogurt company — discusses how business can both save the planet and deliver higher growth and superior profits.

Frightened of the internet? This unit will help you make effective use of the internet, giving you the basic skills required for using web-based resources. Useful tricks and tips are provided as well as information on web browsers, the main features of a browser window, how to look at websites, using hyperlinks, searching for information on the internet, copying text, avoiding computer viruses, and using PDFs.
Losing the Business: The Donners Recall the Great Depression
Created in 1935, the Works Progress Administration (WPA) provided hope and employment for millions of unemployed workers and studied the human toll of the depression. One such study--a series of WPA-conducted interviews with Dubuque, Iowa families--found that middle-class Americans particularly felt the sting and shame of unemployment caused by the depression. In this interview, the Donners discussed the closing of their family-owned printing business in Chicago during tough times. Returning to

1.1.8 Surgical removal of tattoos
This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.
4.4 Genetic diversity and mass extinctions
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef
