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
Students 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 using...
Curated OER
Determination of Phosphates
Young scholars engage in a laboratory instructional activity 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...
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
Pupils perform computer simulations on air dispersion. In this chemistry lesson plan, 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...
Curated OER
Nasa's Return To Flight: Testing In
Students explain basic components of the space shuttle stack and the chemical fuel makeup and storage used on the external tank of space shuttle. They discuss findings of Columbia mission accident. and the safety improvements that have...
Curated OER
Individual Gas Laws
Students learn the relationships between the different properties of a gas and use previous knowledge and make predictions. They predit and explain certain phenomena of gases using their chemical knowledge.
Curated OER
Let it Grow and See What Happens
Students participate in an experiment in which they try to stop algae from growing. In groups, they develop a hypothesis and test it while making changes to the experiment along the way. They make observations and organize their data...
Curated OER
Weathering Experiments: sugar cubes, steel wool and gravel!!
Students study the chemical and physical weathering of "rocks". In this weathering experiments lesson students complete a lab that demonstrates how rocks weather.
Curated OER
Using SWMP Data
Pupils are introduced to the SWMP system which tracks short-and long-term changes in water. Using this data, they plot and interpret the data on a graph to determine how human activities are lowering the water quality. They also identify...
Curated OER
When Things Heat Up
Ninth graders investigate relationship between the temperature and concentration of dissolved oxygen in water. They examine how pollution and other natural influences can cause the parameters to change. In groups, 9th graders collect...
Curated OER
Art: Mirror Of History
Learners show through art how major human events have changed American Culture. Students write in a journal to keep track of studying that is done during the unit. They also create an oral report.
Curated OER
Using A Winogradsky Column to Analyze Microbial Communities
Students use easily obtained materials to study ecological succession in a microbiological community. They collect water samples from outdoor sources in plastic bottles to observe and record changes.
Curated OER
PLANTS LOVE AIR
Learners identify that plants cannot develop adequately without air and predict what happens to the leaf of a geranium brought to class. They draw a picture of what they think the leaf will look like after a week of being covered....
Curated OER
Will It Stretch?
Students describe the effects of temperature change to rubber band's physical properties. In this chemistry lesson, students measure the length of rubber band when temperature changes. They explain why the length varies.
