Don’t be a Stoic about Stoichiometry
Students review balancing chemical equations. In this chemistry lesson, students calculate moles of an unknown substance based on stoichiometric relationships in the balanced equation. They cite applications of stoichiometry in the real...
Curated OER
Life in Extreme Environments - Lakes Under Ice
Young scholars collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess...
Curated OER
Testing for Vitamin C in different drinks and foods
Students develop an awareness of the use of Vitamin C in helping our environment and gain exposure to chemical procedures and techniques. Students analyze and interpret data by keeping a data sheet and making a bar graph.
Curated OER
Tracking Ozone
Learners track an ozone event in Groton, CT. They compare weather changes and the subsequent ozone levels. Also, they make comparisons and determinations about ozone levels.
Curated OER
Ozone Tag
Students explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then
describe the process by which chlorine or bromine compounds can break down ozone molecules.
Curated OER
Virus Tracker
Sixth graders will simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be...
Curated OER
Effects of pH on Organic Molecules
Young scholars investigate the effects of an acid and a base on the structure of milk protein. They observe the changes to droplets of milk when adding ammonia and lemon juice and relate the changes to old, curdled milk. An extension...
Curated OER
Determination of Phosphates
Students engage in a laboratory lesson in order to increase understanding of the impact of phosphates at the chemical and ecological levels. The lab exercise is completed with the goal of getting them to predict the outcomes and future...
Curated OER
Goofy Putty
Students examine mixtures and solution properties by making a borax polymer. In this chemical reactions lesson, students make a putty out of borax solution mixed to create a polymer.
Curated OER
Heat Transfer and Pollution
Students perform computer simulations on air dispersion. In this chemistry lesson, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.
Curated OER
Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...
Curated OER
Mammals, Mammals--Everywhere!
Students explore the habitats of mammals and their physical characteristics. They research examples of mammals that must deal with daily changes in their habitat and how they cope with them. In small groups, students create a table...
