This assessment is a series of short answer questions about Earth's atmosphere based on the lesson "Earth's Atmosphere." Also, there is an article for students to read about the atmospheric effects on baseball games (this is relevant because our school is in Boston, and most of our students are Boston Red Sox fans). You may want to find a different resource for your students, or feel free to use this one.
View planet Earth from the near side of the Moon. Use a model to investigate Earth’s appearance from different positions in the Moon’s orbit. Notice that Earth reflects sunlight in phases similar to the Moon phases seen from Earth. Answer a series of questions by experimenting with the model. For example, position the Moon so that you see a 'full Earth' (maximum reflection of sunlight). This learning object is one in a series of four objects.
This a Flash graphing simulation. You control the amount of solar radiation and the amount of carbon dioxide in the atmosphere. You then see the estimated heat loss, net forcing and resulting temperature change. This is a very simplistic model but is useful to teach about the inputs, outputs and temperature equilibria.
Collection of Chemistry animations. Topics include the atom, formulas and equations, physical properties of matter, periodic table, chemical bonding, properties of solutions, kinetics and equilibrium, acids, bases and salts, and oxidation and reduction.
In this problem set, you will learn about the solvent properties of water, pH, pKa and buffering capacity.
