Stoichiometry: Percent Yield
This NGSS aligned lesson builds on the stoichiometry and limiting and excess reactants concepts. The emphasis of this lesson is on concept development of percent yield. Students will distinguish between actual yield, theoretical yield, and percentage yield. Conceptually, students will understand that the percent yield tells chemists about the efficiency of a reaction. Chemists can then work to improve efficiency in several different ways, and increase percent yield. Students will calculate pe

Population Structure (Population Pyramids)
Population pyramids can tell you a lot about a population. A population pyramid, also called an “ age- gender- pyramid”, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. The structure of a population is determined by the overall proportion of males and females and the proportion of people in different age groups. De

Water Demand and Supply (Developed and Less Developed Countries)
Rivers are vitally important to people. We use them for farming, industry, cooking, washing, toilets, drinking and so much more. Water supply in the UK no longer meets demand. Water supply has become a major issue home and abroad and it is imperative that water companies and people do much more in order to save water. In many areas of the United States, the demand for clean water is likely to increase while supplies decrease due, in part, to a changing climate. Othe

The Urban Heat Island Effect | Video Lesson, Handout, Worksheets | Environment
This lesson covers the concept of urban heat islands (UHI), which refers to cities experiencing higher temperatures than surrounding rural areas due to human activities. It explains that the replacement of natural landscapes with urban surfaces, such as concrete and asphalt, leads to heat absorption and emission, causing the urban heat island effect. Factors contributing to UHIs include waste heat from human activities, urban geometry, reduced natural land cover, urban haze, and wind blocking. T

Ocean Acidification (Carbon Cycle)
Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. The main cause of ocean acidification is the burning of fossil fuels. Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. Many factors contribute to rising carbon dioxide levels. Currently, the burning of fossil fuels such as coal, oil and gas for human industry is one of the major causes. Because of hu
