By making and testing simple balloon rockets, students acquire a basic understanding of Newton's third law of motion as it applies to rockets. Using balloons, string, straws and tape, they see how rockets are propelled by expelling gases, and test their rockets in horizontal and incline conditions. They also learn about the many types of engineers who design rockets and spacecraft.

Students learn how and why engineers design satellites to benefit life on Earth, as well as explore motion, rockets and rocket motion. Through six lessons and 10 associated hands-on activities, students discover that the motion of all objects everything from the flight of a rocket to the movement of a canoe is governed by Newton's three laws of motion. This unit introduces students to the challenges of getting into space for the purpose of exploration. The ideas of thrust, weight and control are explored, helping students to fully understand what goes into the design of rockets and the value of understanding these scientific concepts. After learning how and why the experts make specific engineering choices, students also learn about the iterative engineering design process as they design and construct their own model rockets. Then students explore triangulation, a concept that is fundamental to the navigation of satellites and global positioning systems designed by engineers; by investigating these technologies, they learn how people can determine their positions and the locations of others.

Few classroom topics generate as much excitement as rockets. The scientific, technological, engineering and mathematical foundations of rocketry provide exciting classroom opportunities for authentic hands-on, minds-on experimentation. The activities and lesson plans contained in this educator guide emphasize hands-on science, prediction, data collection and interpretation, teamwork, and problem solving. The guide also contains background information about the history of rockets and basic rocket science. The rocket activities in this guide support national curriculum standards for science, mathematics and technology.
The guide contains new and updated lessons and activities from the original Rockets Educator Guide published in 2003.

In this activity, students revisit the Pop Rockets activity from Lesson 3. This time, however, the design of their pop-rockets will be limited by budgets and supplies. They will get a feel for the limitations of a real engineering project as well as an opportunity to redesign and retest their rockets.

The concepts of stability and equilibrium are introduced while students learn how these ideas are related to the concept of center of mass. They gain further understanding when they see, first-hand, how equilibrium is closely related to an object's center of mass. In an associated literacy activity, students learn about motion capture technology, the importance of center of gravity in animation and how use the concept of center of gravity in writing an action scene.

Students test rocks to identify their physical properties (such as luster, hardness, color, etc.) and classify them as igneous, metamorphic or sedimentary. They complete a worksheet table to record all of the rock properties, and then answer worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.

This art history video discussion examines Auguste Rodin's "The Gates of Hell" 1880-1917, plaster (Musee d'Orsay, Paris).When the building, earlier on the site of the Musee d'Orsay in Paris, was destroyed by fire during the Commune in 1871, plans were drawn up to replace it with a museum of decorative arts. Rodin won the competition to design a great set of doors for its entry way. Although the museum was never built, Rodin continued to work on the doors. They became an ongoing project; a grand stage for his sculptural ideas. It's fitting that the plaster of this great unfinished sculpture, The Gates of Hell, is now on display at the d'Orsay, the former railway terminal that was built on this site instead of the museum of decorative arts and that, by lovely coincidence, was converted into one of the world's great art museums.

In this paper and pencil exercise, students create graphs that describe the effect of a series of experiments using Daisy World, an energy balance model, that can be used to demonstrate concepts of equilibrium, homeostatis, and positive and negative feedbacks. Internet access and exploration with the actual Daisy World model is ideal, but not required. The resource is Activity 6 of the learning module, Global Balance, part of the lesson series Potential Impacts of Climate Variability and Change.

Through this activity, students come to understand the environmental design considerations required when generating electricity. The electric power that we use every day at home and work is usually generated by a variety of power plants. Power plants are engineered to utilize the conversion of one form of energy to another. The main components of a power plant are an input source of energy that is used to turn large turbines, and a method to convert the turbine rotation into electricity. The input sources of energy include fossil fuels (coal, natural gas and oil), wind, water, nuclear materials and refuse. This activity focuses on how much energy can be converted to electricity from many of these input sources. It also considers the impact of the by-products associated with using these natural resources, and looks at electricity requirements. To do this, students research and evaluate the electricity needs of their community, the available local resources for generating electricity, and the impact of using those resources.

his task is intended as a classroom activity. Student pool the results of many repetitions of the random phenomenon (rolling dice) and compare their results to the theoretical expectation they develop by considering all possible outcomes of rolling two dice. This gives them a concrete example of what we mean by long term relative frequency.

The Romans developed a lot of infrastructure like roads and aqueducts to both help their cities flourish and to... you know... be better at war. But the interesting thing about Roman Engineering is how it was almost all focused on Techne and not Episteme. In this episode of Crash Course History of Science, Hank takes us down the road of road building, domes, and some really cool cement.

In which Mike delves into the theater of ancient Rome. It wasn't all gladiators and Christian-killing, you know. There was theater, too. Roman drama drew heavily on Greek drama. So heavily, in fact, that many of the stories and characters were lifted directly from Greek plays. This time around, you'll learn about Plautus, Terence, and Seneca, and just what they owe to Menander.

Students explore whether rooftop gardens are a viable option for combating the urban heat island effect. Can rooftop gardens reduce the temperature inside and outside houses? Teams each design and construct two model buildings using foam core board, one with a "green roof" and the other with a black tar paper roof. They measure and graph the ambient and inside building temperatures while under heat lamps and fans. Then students analyze the data and determine whether the rooftop gardens are beneficial to the inhabitants.

Familiarity with Greek and Latin roots, as well as prefixes and suffixes, can help students understand the meaning of new words. This article includes many of the most common examples.
Included in the article are downloads of Common Latin Roots chart, Common Greek Roots chart, Common Prefixes chart, Common Suffixes chart.

Students learn about rotary encoders and discover how they operate through hands-on experimentation. Rotary encoders are applied in tools to determine angle measurements and for translations of angular motion. One common rotary encoder application is in a computer's ball-type mouse—the ball itself is a type of rotary encoder. In this activity, students experiment with two rotary encoders, including one from a computer mouse and one created using a LEGO® MINDSTORMS® NXT kit. They collect data to define and graph the relationship between the motion of the rotary encoder and its output.
