Estimating Exchange Rates of Water in Embayments using Simple Budget Equations. part of Quantitative Skills:Activity Collection
Simple budgets may be used to estimate the exchange of water in embayments that capitalize on the concept of steady state and conservation principals. This is especially true for bays that experience a significant exchange of freshwater. This exchange of freshwater may reduce the average salt concentration in the bay compared to seawater if it involves addition of freshwater from rivers, R, and/or precipitation, P. Alternatively, it may increase the average salt concentration in the bay compared to seawater if there is relatively little river input and high evaporation, E. Since freshwater input changes the salt concentration in the bay, and salt is a conservative material, it is possible to combine two steady state budgets for a bay, one for salt and one for water, to solve for the magnitude of the water flows that enter and exit the bay mouth. Students will make actual calculations for the inflow and outflow of water to Puget Sound, Washington and the Mediterranean Sea and compare them to actual measured values.

Stream Characteristics Lab part of Quantitative Skills:Activity Collection
Students determine the relationship between the sinuosity of a river and its gradient by calculating gradients and sinuosity, and generating a graph on Excel. They then test the relationship by making measurements on a picture generated on Google Earth.

The Changing Geographic Distribution of Malaria with Global Climate Warming part of Quantitative Skills:Activity Collection
In this exercise, students analyze climate data to find areas in the southern United States that are now close to having conditions in which the malaria parasite and its mosquito hosts thrive and then attempt to forecast when areas might become climatically suitable.

Earthquake Shaking and Damage part of Quantitative Skills:Activity Collection
This student homework and problem set has students quantitatively earthquake hazard, shaking and damage.

Cycles of the Sun and Moon part of Quantitative Skills:Activity Collection
This activity asks students to download sunrise and sunset data along with moon phase data and graph these data sets together in a spreadsheet in order to visualize the cycles of the seasons and the moon.
