The Center for Critical Thinking
Critical thinking is an elusive concept because it isn't about anything concrete or content oriented. Critical thinking is a way of looking at the world, forming questions, and answering them. Because of their intangible nature, critical-thinking skills can be difficult to teach. The /cthink Web site is a great place for ideas about how to encourage the development of critical-thinking skills in students. The site includes K to 12- and university-level sections, each with its own set of resources and library of articles.

Strategies That Work
Comprehensive collection of links to varied activities that promote success in the classroom and critical thinking.

Fingerprints
Students observe and classify fingerprint patterns, identify ridge characteristics, and relate fingerprints to art, writing, math, and history.

Predictable Patterns
Patterns are trends, such as radioactive decay and the colonization of intertidal zones. They are cycles, changes occuring over time, such as life cycles, seasonal cycles, planetary cycles and tidal cycles. There are even irregular patterns such as the predator-prey relationship and plant succession events. Recognizing a pattern can help us make predictions about what happens next. Patterns help to tell us what to expect from our world. This site contains six simple classroom activities that help students discover and recognize patterns.

Fingerprints, a Classification System
This lesson allows students to discover the usefulness of grouping things according to similarities and differences. It is a good introduction to classification systems in Life science.

Patterns in Nature
One practice learning activity to develop the ability to recognize patterns is to group words (nouns; verbs) so that they reflect existing relationships. The nouns used to illustrate this lesson include moving vehicles. Some move through air, others in water, and others on land. Students should be able to recognize a distinct pattern in their grouping so that, when a new word is added, it can be placed into an existing category. Many groupings are appropriate. This sorting activity is intended to precede instruction on the periodic chart.

Classifying Galaxies
Students practice the technique, useful in science, of engaging a scheme or plan to classify objects in a group. In this lesson students look at images of different kinds of galaxies, taken by the world's best telescopes. In most high school astronomy texts and in some earth science texts, the Hubble Tuning Fork Diagram is presented as a way to classify, or put into groups, the various types of galaxies observed in space. The lesson follows, in an organized way, the process by which scientists group or classify objects in nature.

Variation and classification Lesson Plans

They then conduct the experiment and make a recommendation to the cafeteria workers. Contains suggested assessments, teacher's guide and complete instructions for students.

Crisis at Fort Sumter
An interactive historical simulation and decision making program. Using text, images, and sound, it reconstructs the dilemmas of policy formation and decision making in the period between Abraham Lincoln's election in November 1860 and the battle of Fort Sumter in April 1861. The program primarily focuses on Lincoln, both as President-elect and as President. Viewers place themselves in Lincoln's position, consider the events that transpire, and choose a course of action at five critical junctures, called "problems." At each of these five junctures, Lincoln made a decision that helped determine the outcome of the crisis at Fort Sumter. In order to assess each problem and make a decision, advice is available from official advisors, such as cabinet members, and from various informal channels, such as newspapers, friends, and public spokesmen. The program divides the information about the Sumter crisis into nine chronological sections. The text within the sections also contains hotword links that permit viewers to explore information in a topical rather than a chronological manner and commentary links that provide additional information including material about debates among historians about events, action, or people. The site also contains an extensive bibliography on the civil war.

Eli Whitney's Patent for the Cotton Gin
This lesson relates to the power of Congress to pass laws related to the granting of patents, in particular, Eli Whitney's Patent for the cotton gin. As Eli Whitney left New England and headed South in 1792, he had no idea that within the next seven months he would invent a machine that would profoundly alter the course of American history. While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for the planters that it greatly increased their demand for both land and slave labor. In 1790 there were six slave states; in 1860 there were 15. From 1790 until Congress banned the importation of slaves from Africa in 1808, Southerners imported 80,000 Africans. By 1860 approximately one in three Southerners was a slave. Because of the cotton gin, slaves now labored on ever-larger plantations where work was more regimented and relentless. As large plantations spread into the Southwest, the price of slaves and land inhibited the growth of cities and industries. In the 1850s seven-eighths of all immigrants settled in the North, where they found 72% of the nation's manufacturing capacity. The growth of the "peculiar institution" was affecting many aspects of Southern life.

Inventing the Solar System: Early Greek Scientists Struggle to Explain How the Heavens Move
Since the first Egyptian farmers discovered the annual reappearence of Sirius just before dawn a few days before the yearly rising of the Nile, ancient civilizations around the Mediterranean have sought to explain the movements of the heavens as a sort of calendar to help guide them conduct earthly activities. Counting phases of the moon or observing the annual variations of daylength could, after many years' collection of observations, serve as vital indicators for planting and harvesting times, safe or stormy season for sailing, or time to bring the flocks from winter to summer pastures. With our millenia of such observation behind us, we sometimes forget that seeing and recording anything less obvious than the rough position of sun or nightly change of moonphase requires inventing both accurate observation tools (a stone circle, a gnomon used to indicate the sun's shadow, a means to measure the position of stars in the sky) and a system of recording that could be understood by others (how many fingers' width or degrees is that star from the horizon? Which direction is due north?).
