This video explains how to identify figures of speech and figurative language through a series of questions. (01:35)
What Happened to our Dear Aunt Sally?
An Introduction to Surface Chemistry
Theoretical and descriptive material for an introductory surface science course. Topics covered include structure of surfaces and detailed information on a variety of surface analytical techniques, essentially an online text.
The effects of acid rain on a stream in the forest
Cars and power plants that burn fossil fuels release smoke that is full of chemicals. These chemicals float into the atmosphere, get trapped in clouds, and make the rain more acidic. This is known as acid rain.
Sonia Sanchez: The Meaning of Malcolm X
Poet Sonia Sanchez, interviewed here for Eyes on the Prize, describes what the outspoken civil rights leader Malcolm X represented to African Americans in the 1960s.
Students learn about weight and drag forces by making paper helicopters and measuring how adding more weight affects the time it takes for the helicopters to fall to the ground.
Students design and build a paper rocket around a film canister, which is used as the engine. An antacid tablet and water are put into the canister, react to form carbon dioxide gas, and act as the pop rocket's propellant. With the lid snapped on, the continuous creation of gas causes pressure to build up until the lid pops off, sending the rocket into the air. The pop rockets demonstrate Newton's third law of motion: for every action, there is an equal and opposite reaction.
Come On Over Rover
Have you ever wondered why it takes such a long period of time for NASA to build space exploration equipment? What is involved in manufacturing and building a rover for the Red Planet? During this lesson, students will discover the journey that a Mars rover embarks upon after being designed by engineers and before being prepared for launch. Students will investigate the fabrication techniques, tolerance concepts, assembly and field-testing associated with a Mars exploratory rover.

Retailing in Leeds - Consumer Shopping preferences
Leeds is a major city in the UK and as such is a magnet for shoppers from the surrounding region. Around 1.7 to 1.9 million people are in the catchment area as shoppers in Leeds city centre. Consequently retail is an important business for Leeds. John Temperley Senior Lecturer in Marketing in the Business School and a retail specialist, explains the choices that face consumers and what their preferences are, based on research by students sponsored by Leeds city centre management. The results ar
