Carbon, Greenhouse Gases, and Climate
Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...
Cornell University
The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...
Curated OER
Desalination: Creating a Solar Still
To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...
Curated OER
Temperature and the Tomato
You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this lesson. Your class monitors daily temperature and insolation amounts over a two week span of time....
Curated OER
Oxygen
Students explore oxygen and its physical and chemical propeties. In this investigative lesson students complete several experiments using oxygen.
Curated OER
Chemical Reactions
In this chemical reactions worksheet, students determine the order of a reaction based on experimental results. This worksheet has 5 problems to solve.
Curated OER
The Nature Of Dissolving Processes
Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.
Curated OER
Coordination Compounds
In this coordination compounds worksheet, students determine the name, coordination sphere, center of coordination, ligands, and coordination number for given compounds. This worksheet has 5 fill in the blank questions.
Curated OER
Review Sheet for Matter Test
In this matter worksheet, students answer five questions about the law of conservation of mass. They identify substances as solids, liquids, gases or mixtures and they identify given items as matter or energy.
Curated OER
Teaching the Scientific Method Using Adhesives
Students research on the history of adhesives. In this science lesson, students select one test to use in finding the stickiness of adhesives. They collect data and formulate a conclusion.
