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.

BotEC: Weight of Gold part of Quantitative Skills:Activity Collection
Question Let's suppose that you have a shoe box full of water (the box is waterproof, of course). The shoe box weighs about 9 kg (19.8 pounds). Suppose you emptied the box and filled it completely with rock ...

Quantitative Classroom Exercises part of Quantitative Skills:Activity Collection
The four exercises give students an opportunity to use their knowledge of graphs, algebra, and maps to solve simple geological problems.

Gulf Anoxia Course Project part of Quantitative Skills:Activity Collection
In this activity students work in groups to investigate the problem of Gulf of Mexico hypoxia before developing mitigation strategies based on local contriubtions to the problem. The students present their ideas in a public meeting debate format from which a solution must be selected by the entire class.

Three-Point Problem by Simultaneous Linear Equations part of Quantitative Skills:Activity Collection
Students are introduced to the use of linear algebra in an intuitive and accessible way, through classroom activity and homework set. The familiar three-point problem is cast in terms of three dimensional analytic geometry, fostering understanding of mathematical models for simple geometric forms.

Floods over time: death vs. destruction part of Quantitative Skills:Activity Collection
This exercise looks at the dollar losses and deaths caused by flooding in the US, and at the causes of, and relationships between the two trends.

Weathering of Minerals part of Quantitative Skills:Activity Collection
Students determine the % change in mass of mineral samples that have been placed in a rock tumbler. They graph the relationship between the hardness of the mineral and the % change in mass. They then consider why some of the mineral samples do not conform the the relationship they graphed. They investigate the physical properties of the outliers and consider how the physical properties contributed to the rate of weathering, and what kind of weathering occured in the rock tumbler.
