This is a hands-on activity to learn that energy can be transformed into various forms. Potential energy is converted into kinetic energy. Moreover, this kinetic energy can be used (if more than the relative binding energy) to break atoms, particles and molecules to see “inside” and to study their constituents.

Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect, the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers, themselves and the Earth. In an associated literacy activity, students learn how a bill becomes law and research global warming legislation.

Students learn how the sun can be used for energy. They learn about passive solar heating, lighting and cooking, and active solar engineering technologies (such as photovoltaic arrays and concentrating mirrors) that generate electricity. Students investigate the thermal energy storage capacities of test materials. They learn about radiation and convection as they build a model solar water heater and determine how much it can heat water in a given amount of time. In another activity, students build and compare the performance of four solar cooker designs. In an associated literacy activity, students investigate how people live "off the grid" using solar power.

This lesson introduces students to three of the six simple machines used by many engineers: the lever, the pulley, and the wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines helps determine their ability to make work easier or make work faster.

The Levitating Astronaut activity uses the amazing power of magnets to help children learn about magnetism and gravity.

In this lesson, students will extend their knowledge of matter and energy cycles in an organism to engineering life cycle assessment of a product. Students will learn about product life cycle assessment and the flow of energy through the cycle, comparing it to the flow of nutrients and energy in the life cycle of an organism.

Trade was critical to Old Babylonia, where many highly prized natural resources were scarce but agricultural goods were in surplus. A vibrant trading system developed, bringing manufactured goods and raw materials from as far as Turkey, and even India, 1500 miles away. Trade became integral to the economy and the culture. In this lesson, students explore the trade industry in Old Babylonia and its far-flung influence.

Students are introduced to the International Space Station (ISS) with information about its structure, operation and key experiments. The ISS itself is an experiment in international cooperation to explore the potential for humans to live in space. The space station features state-of-the-art science and engineering laboratories to conduct research in medicine, materials and fundamental science to benefit people on Earth as well as people who will live in space in the future.

In this lesson, students learn about the physical properties of the Moon. They compare these to the properties of the Earth to determine how life would be different for astronauts living on the Moon. Using their understanding of these differences, they are asked to think about what types of products engineers would need to design for us to live comfortably on the Moon.

Growth and development through the life span including physical, social, cognitive and neurological development. Topics covered included daycare, education, disabilities, parenting, types of families, gender identity and roles, career decisions, illnesses and treatments, aging, retirement, generativity, and dying.Login: guest_oclPassword: ocl

Through an introduction to the design of lighting systems and the electromagnetic spectrum, students learn about the concept of daylighting as well as two types of light bulbs (lamps) often used in energy-efficient lighting design.

Students learn about the basic properties of light and how light interacts with objects. They are introduced to the additive and subtractive color systems, and the phenomena of refraction. Students further explore the differences between the additive and subtractive color systems via predictions, observations and analysis during three demonstrations. These topics help students gain a better understanding of how light is connected to color, bringing them closer to answering an overarching engineering challenge question.

Students are introduced to the correct technical vocabulary for lighting, which is different than layperson's terms. They learn about lamp (light bulb) technology and how to identify the various types of lighting in their spaces. They are also introduced to lighting controls as a means for saving energy- reducing costs, human energy consumption, and greenhouse gas emissions on the environment. Using an accompanying worksheet, students embark on a guided audit in which they survey the lighting in their classroom and identify the potential savings from using controls.

This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.

The lessons in this unit provide an opportunity for students to learn about and discuss two U.S. families in which both the father and son became President.

Relive the decisions that led to the attack on Fort Sumter to determine whether Lincoln aimed to preserve peace or provoke the hostilities that led to the Civil War.

Students explore the historical context and significance of Lincoln's inaugural address through archival documents.

The most important festival in the Chinese calendar is the New Year or Spring Festival. One of the annual events used to commemorate the festival is a colorful parade complete with animated dragon and lion figures.

In the first activity the student will learn the major differences between Eastern and Western dragons and discover why Eastern dragons are associated with Chinese New Year. They will hear a story about how the dragons came to rule major rivers of China. In the second activity, they will also learn about the Chinese New Year Dragon Parade and discover why firecrackers are used to drive off evil spirits, especially one called the Nian. In the third activity the students will see images of parading dragons, including sound-enhanced video and read poems about the New Year. In the fourth lesson the students will discover that the Chinese lion has imaginary characteristics similar to the dragon. They will view images of the lion and hear about how this highly stylized beast once fought the ferocious Nian. They will learn about the lion dancers in the New Year parade and compare them to the dragon dancers. Finally they will make their own lion masks.

Students create arrangements of a melody and listen to recordings contrasting in style and genre.
