Antiobiotic Resistance

(View Complete Item Description)

In the explorable explanation players can learn how antibiotic resistance happens. They can interact with bacteria in this simulation to learn how when living things reproduce, there is a small amount of variance in their offspring. This allows organisms to respond to changes in their environment over several generations. Applied to bacteria, when they treated with antibiotics, only the strongest survive and multiply, creating an increasing resilient population.

Physics of Roller Coasters

(View Complete Item Description)

Students explore the physics utilized by engineers in designing today's roller coasters, including potential and kinetic energy, friction, and gravity. First, students learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they also consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars as they travel around the track. During the associated activity, the students design, build, and analyze a roller coaster for marbles out of foam tubing.

The Case of the Dividing Cell: Mitosis and Meiosis in the Cellular Court

(View Complete Item Description)

The Honorable Judge Cellular is presiding over the case of The State vs.Egg Cell Number 6624223. As the prosecuting attorney calls each witness to the stand and the courtroom drama unfolds, students learn about the stages of mitosis and meiosis and their particular characteristics, and how cell division in prokaryotes differs from that in eukaryotes. The case is suited to an introductory biology course and would also work well in high school biology classes.

Above-Ground Storage Tank Design Project

(View Complete Item Description)

At this point in the unit, students have learned about Pascal's law, Archimedes' principle, Bernoulli's principle, and why above-ground storage tanks are of major concern in the Houston Ship Channel and other coastal areas. In this culminating activity, student groups act as engineering design teams to derive equations to determine the stability of specific above-ground storage tank scenarios with given tank specifications and liquid contents. With their floatation analyses completed and the stability determined, students analyze the tank stability in specific storm conditions. Then, teams are challenged to come up with improved storage tank designs to make them less vulnerable to uplift, displacement and buckling in storm conditions. Teams present their analyses and design ideas in short class presentations.

Abraham Lincoln’s Crossroads

(View Complete Item Description)

Abraham Lincoln’s Crossroads is an educational game based on the traveling exhibition Lincoln: The Constitution and the Civil War, which debuted at the National Constitution Center in June 2005. The online game is intended for advanced middle- and high-school students. It invites them to learn about Lincoln’s leadership by exploring the political choices he made. An animated Lincoln introduces a situation, asks for advice and prompts players to decide the issue for themselves, before learning the actual outcome. At the end of the game, players discover how frequently they predicted Lincoln’s actions. A Resources Page keyed to each chapter provides links to relevant Websites on Lincoln and the Civil War, permitting students to explore issues in more depth

The Bill of Rights: Debating the Amendments

(View Complete Item Description)

In this lesson, students will examine a copy of twelve possible amendments to the United States Constitution as originally sent to the states for their ratification in September of 1789. Students will debate and vote on which of these amendments they would ratify and compare their resulting “Bill of Rights” to the ten amendments ratified by ten states that have since been known by this name.

The Constitutional Convention (TAH)

(View Complete Item Description)

This Web Site provides a twelve-step guide to understanding the Constitutional Convention. The fundamental difficulty facing teachers and students of the Constitutional Convention of 1787 is how to make sense of the vast and complex material. The resources on this site help teachers teach the Convention and engage students with the conversation and arguments that took place over its four months. Primary sources, artwork, a dramatic reading and lesson plans are included.

3RC (Reduce, Reuse, Recycle and Compost)

(View Complete Item Description)

In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).

Wizardry and Chemistry

(View Complete Item Description)

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.

Air Pollution

(View Complete Item Description)

Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By learning some fundamental meteorology concepts (air pressure, barometers, prediction, convection currents, temperature inversions), students learn the impact of weather on air pollution control and prevention. Looking at models and maps, they explore the consequences of pollutant transport via weather and water cycles. Students are introduced to acids, bases and pH, and the environmental problem of acid rain, including how engineers address this type of pollution. Using simple models, they study the greenhouse effect, the impact of increased greenhouse gases on the planet's protective ozone layer and the global warming theory. Students explore the causes and effects of the Earth's ozone holes through an interactive simulation. Students identify the types and sources of indoor air pollutants in their school and home, evaluating actions that can be taken to reduce and prevent poor indoor air quality. By building and observing a few simple models of pollutant recovery methods, students explore the modern industrial technologies designed by engineers to clean up and prevent air pollution.

Here Comes the Hurricane! Saving Lives through Logical Reasoning and Computer Science

(View Complete Item Description)

Students use a hurricane tracking map to measure the distance from a specific latitude and longitude location of the eye of a hurricane to a city. Then they use the map's scale factor to convert the distance to miles. They also apply the distance formula by creating an x-y coordinate plane on the map. Students are challenged to analyze what data might be used by computer science engineers to write code that generates hurricane tracking models. Then students analyze a MATLAB® computer code that uses the distance formula repetitively to generate a table of data that tracks a hurricane at specific time intervals. Students come to realize that using a computer program to generate the calculations (instead of by hand) is very advantageous for a dynamic situation like tracking storm movements. Their inspection of some MATLAB code helps them understand how it communicates what to do using mathematical formulas, logical instructions and repeated tasks. They also conclude that the example program is too simplistic to really be a useful tool; useful computer model tools must necessarily be much more complex.
