This is an Internet-based probability and statistics E-Book. The materials, tools and demonstrations presented in this E-Book would be very useful for advanced-placement (AP) statistics educational curriculum. The E-Book is initially developed by the UCLA Statistics Online Computational Resource (SOCR). However, all statistics instructors, researchers and educators are encouraged to contribute to this project and improve the content of these learning materials. There are 4 novel features of this specific Statistics EBook. It is community-built, completely open-access (in terms of use and contributions), blends information technology, scientific techniques and modern pedagogical concepts, and is multilingual.

In this problem set students construct a P-T phase diagram for the aluminosilicate polymorphs based on experimental phase equilibria and application of the Clausius-Clapeyron equation. The problem set uses unit cell volume, molar entropy, and phase equilibrium data culled from the primary literature. It leads students through the exercise in step-by-step fashion starting with a brief explanation of the Clausius-Clapeyron equation. The main goals are to help students understand how thermodynamics can be useful for solving real geologic problems, to provide some insights into the nature and construction of P-T phase diagrams, and to provide experience in dealing quantitatively with real data.

In week one of the exercise students determine stream discharge by doing some tedious, but simple hand calculations using data sets provided by the instructor. The following week is designed to be more hands-on. Here, they collect their own field data and create a spreadsheet to perform the calculations more efficiently and accurately. By collecting the data themselves, students gain a more thorough understanding of how stream discharge is both measured and computed; they also learn how the results can be used to determine groundwater baseflow. The fact they do hand calculations prior to creating the spreadsheet helps build their math skills and reduces the "black-box" effect that often develops when using software for data analysis. Students also gain valuable experience creating spreadsheets and learn how this tool can be used to perform repetitive computations more efficiently and with less error. Finally, this exercise asks students to consider the accuracy of their replicate field measurements through a series of questions related to their standard deviation and percent error calculations.

This unit applies a spreadsheet, based on the storm water hydrograph modeling module, that applies the widely utilized Rational Method to estimate hydrographs and flooding for urban watersheds. The specific structure of the model is based on assumptions encoded for Maricopa County, Arizona, which is an urbanized area in the Desert Southwest of the USA, so the model is directly applicable to any similar climate. The model is broadly applicable to urban watersheds anywhere in the world, if appropriate adjustments are made to model parameters and if the necessary input data can be obtained. This model is designed to be utilized in parallel with a modeling guide by the same authors and alongside conceptual instruction in the hydrological concepts of rainfall and runoff processes in undergraduate classrooms. Hydrology and/or computational learning outcomes are assessed using a validated pre/post assessment instrument included with the unit.

This is a short experimental study of what happens to aluminum hydroxide, silicic acid, magnesium oxide, and calcium carbonate (or reagents of instructors choice) when they are heated to 110 and 1200 degrees.
Students determine the formula and calculate the mole percent and weight percent of each element and oxide in each reagent. They heat the samples and calculate percentage weight loss or gain. Finally, they write a lab report summarizing their results.
Be sure to have students save their samples for later use in a lab that introduces X-ray diffraction.

Really Ancient Fossils STEM Kit. The Natural Sciences Education & Outreach Center collaborates with CSU faculty, National Parks and citizen science programs to translate their current scientific research into unique STEM experiences for students in the form of Educational Kits that can be checked out. Each kit contains just about all of the materials needed (minus common things like water and paper towels) to explore some really interesting scientific research topics.The kits are available for teachers and informal educators in Colorado to check out for a duration of a week by submitting either a local pickup form or a delivery form available at the linked website. Due to the extreme weight of the sand used in this Kit, local pickup is the only option. This kit is provided free for educational use. This kit is also available in Spanish.

The inquiry method and meteorological and astronomical online data can be used to elicit the inconsistencies of students' na��ve ideas about the "real" reasons for the seasons. The first phase of this two-part investigation uses online meteorological data to identify factors that might explain differences of seasonal temperatures among cities These factors are used to hypothesize why differences of seasonal temperatures occur among cities. During the second phase, the variables and hypotheses that were previously identified in part one are used to design and conduct an inquiry-oriented investigation. Astronomical data is used as part of the investigation to "test" students' hypotheses -- conclusions are drawn then communicated.

In this activity, students replicate the slope failure experiment presented by Densmore et al. (1997) in the journal Science. They are given the original article and the slope failure apparatus (along with all associated materials) and then they need to figure out how to replicate the experiment. Once they have completed an experimental run of sufficient length, they compile and analyze their data and compare it to the article's results.
After completing this portion of the lab, the students read the discussion and reply (Aalto et al., 1998; Densmore et al., 1998) and critically evaluate they results of the experiment and its applicability to the real world and landscape evolution.
