Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

There has been a huge solar energy spill! Let's go outside to play in it. This lesson includes multiple experiments showcasing solar and wind energies. Scholars build a solar heater and an anemometer before testing the results. The...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...

How do scientists know what Earth's climate was like millions of years ago? Young environmental scholars discover how researchers used proxy data to determine the conditions present before written record. Grouped pupils gain experience...

In this speaking and listening worksheet, students improve oral language skills by collaborating with a classmate in a dialogue about going to a doctor's office.

The carbon cycle isn't a bike which produces carbon and this lesson explains why. Through reading and discussion, groups of pupils create visual explanations of the four parts of the carbon dioxide oxygen cycle. Activities...

An overview of the history, applications and science of superconductivity, including the Meissner effect, BCS theory, Type 1 and Type 2 superconductors and high-temperature superconductivity.

J. Georg Bednorz jointly revolutionized superconductivity research with K. Alex Muller by discovering an entirely new class of superconductors, often referred to as high-temperature superconductors. They managed to achieve...

While still in graduate school, John Robert Schrieffer developed with John Bardeen and Leon Cooper a theoretical explanation of superconductivity that garnered the trio the Nobel Prize in Physics in 1972. The BCS theory (the acronym...

In their search for new superconductors, Swiss theoretical physicist Karl Alexander Muller and his young colleague, J. Georg Bednorz, abandoned the metal alloys typically used in superconductivity research in favor of a class of oxides...

This site provides an extensive amount of weather information. Includes current information, forecasting, and historic weather related events. Weather map symbols and terminology explained.

Piute Ground Squirrels are adapted to desert life. Their kidneys efficiently conserve water, and they are able to withstand high temperatures. Learn more about the Spermophilus mollis, more commonly known as a Piute Ground Squirrel, in...

The physical property of malleability is explained. The importance of malleability to various physical processes is discussed. Examples of materials with high malleability are identified.

View facts about the climate of El Salvador compiled by GeographyIQ from selected publications of the U.S Department of State and from the CIA World Fact Book. Peruse the tables of data about average temperature highs and lows for three...
