Students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and on that basis, learn to make an educated guess about the meaning of a word. Students are introduced to the role played by metaphor in language development.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students work with ratio and proportion and the concept of mole to calculate the number of molecules of ozone in a volume of air from concentration data.

Students carry out a naturalistic observation study in order to test the hypothesis that there are sex differences in risk-taking. Students collect and analyze data and prepare APA style research report.

Students use a spreadsheet to compute the hypothetical risk of an Andrew-like hurricane to downtown Miami.

Students use spreadsheets to analyze the reasons why New Orleans has subsided in the past 250 years.

This task presents a foundational result in geometry, presented with deliberately sparse guidance in order to allow a wide variety of approaches. Teachers should of course feel free to provide additional scaffolding to encourage solutions or thinking in one particular direction. We include three solutions which fall into two general approaches, one based on reference to previously-derived results (e.g., the Pythagorean Theorem), and another conducted in terms of the geometry of rigid transformations.

The construction of the tangent line to a circle from a point outside of the circle requires knowledge of a couple of facts about circles and triangles. First, students must know, for part (a), that a triangle inscribed in a circle with one side a diameter is a right triangle. This material is presented in the tasks ''Right triangles inscribed in circles I.'' For part (b) students must know that the tangent line to a circle at a point is characterized by meeting the radius of the circle at that point in a right angle: more about this can be found in ''Tangent lines and the radius of a circle.''

Students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. They do this by attempting to identify several different foods that have similar textures. For some of the attempts, students hold their noses and close their eyes, while for others they only close their eyes. After they have conducted the experiment, they create bar graphs showing the number of correct and incorrect identifications for the two different experimental conditions tested.

This real world word problem about calculating a tip in a restaurant requires multiple steps.

This task is not about computing the final price of the shirt but about using the structure in the computation to make a general argument.

This simple conceptual problem does not require algebraic manipulation, but requires students to articulate the reasoning behind each statement.

The Teacher’s Guide to Using Literature to Promote Inclusion of People with Disabilities has been designed to assist teachers who wish to use literature to promote inclusion of people with disabilities in all aspects of life. The Guide consists of two parts. Part 1 is a rubric for evaluating how short stories, books, poems, TV programs, movies, digital media, and other forms of literature portray characters with disabilities. Part 2 of the Teacher’s Guide to Using Literature to Promote Inclusion of People with Disabilities is a curriculum guide with learning objectives, lesson activities, and strategies for outcome evaluation. The curriculum guide is a resource for teachers who wish to design lessons using literature to teach about disabilities.

This article provides an overview of energy education curriculum materials available from the National Energy Education Development (NEED) Project. Teachers may become a member, or use free online resources.

Principles of economics students are asked to collect and analyze data on a few macro economic aggregates to give them a first taste of empirical work.

Landscape evolution provides a convenient framework for understanding geologic time and rates because students can observe how processes like erosion and deposition shape their surroundings, even in urban settings. In order to describe landscapes qualitatively and quantitatively, students build 3-D sandbox models based on topographic maps and design and stage a "virtual adventure race." Sandbox landscapes are used to illustrate erosional processes, the role of water in sediment transport, relief change, and how erosion exhumes rocks from depth, while local examples are used to discuss landscapes as transient or steady over different time- and length scales. To convince students that the observed processes act over millions of years to shape Earth's surface, quantitative dating tools are introduced. Dice experiments illustrate radioactive decay and the shape of the age equation curve, and 14C dating, geochronology and thermochronology are introduced as "stopwatches" that start when a plant dies, a crystal forms, or a rock nears the surface and cools to a certain temperature.
The sandbox model and thermochronometer "stopwatches" are combined to measure erosion rates at a point, uniform and spatially variable erosion, and rates of landscape change. Ultimately, model rates (cm/hour) calculated from stopwatch times on the order of seconds can be related to geologic rates (km/My) calculated from real million-year-old samples. SEE POSTER for detailed descriptions of each activity in Parts 1-4 (complete with specific Learning Goals, Context, Materials, Activity Summary, Evaluation, and adaptation to challenge students in grades 9-16).

The goal of this activity is for students to develop visual literacy. They learn how images are manipulated for a powerful effect and how a photograph can make the invisible (pollutants that form acid rain) visible (through the damage they cause). The specific objective is to write captions for photographs.

This version of Go Fish allows students to practice recognizing and saying the teen numbers.

In this task students are given graphs of quantities related to weather. The purpose of the task is to show that graphs are more than a collection of coordinate points, that they can tell a story about the variables that are involved and together they can paint a very complete picture of a situation, in this case the weather.

These unit conversion problems provide a rich source of examples both for composition of functions (when several successive conversions are required) and inverses (units can always be converted in either of two directions).

This investigation uses the relationship between volume and temperature to reinforce the ideal gas law. It also uses the data collected to find absolute zero.
