In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.

This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.

In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create the final solution. Next, they prepare the solution using the appropriate glassware, and then can check their answer using the concentration viewer in the solution info panel.

In this field-based exercise, students were given a tour of an abandoned mine site and asked to utilize a set of field measurements to describe the spatial details of metal transport. This drew on previous experience with field measurements and prompted them to work together to solve an observed chemical evolution of a contaminated brook. The exercise is an excellent example for students to bring together acid-base chemistry, redox chemistry, and thermodynamic concepts together to describe a reasonably complex system. The field component was completed in a full day, but we will be expanding this next fall for a 2 day exercise (weekend). The exercise was coupled with subsequent labs to complete analysis of the water samples and accomplish speciation calculations using PHREEQCI.

Intended Audience: This activity was used for an introductory Geochemistry class, which contained students from sophomore level to master's students. We took the trip in mid-October, about as late as possible in Vermont, after they had gained some previous field experience and lab work in addition to an in introduction to these principles in class.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.

Students research the acidification of freshwater streams and lakes, identify at least one of the sources, and determine how their daily activities contribute to the problem.

Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

This lesson employs direct instruction and small-group discussion to help students learn new vocabulary skills while reading Patricia Polacco's "Pink and Say".

This online tool enables students to learn about and write acrostic poems. Elements of the writing process are also included.

Students create acrostic poems using their names and the names of things that are important to them.

Creating an illustrated alphabet book of action words, from "attack" to "zap", reinforces the definition of verbs as it stretches and expands students' vocabulary.

Students must "become" a character in a novel in order to describe themselves and other characters using powerful adjectives.

Students construct rockets from balloons propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.

This assignment is a 10-hour, out-of-class project where each student
designs and carries out an action plan to enhance sustainability.
Students select from a large suite of alternative actions, most of which
can be quantified for reductions in CO2 and energy consumption, as well
as in dollar savings.

This recurring lesson encourages students to comprehend their reading through inquiry and collaboration. They choose important quotations from the text and work in groups to formulate "quiz" questions that their peers will answer.

By far most field trips in structural geology and regional tectonics do NOT take place in large urban centers with a trip focus on mitigation of hazards. What is described here is an example of the instructional and learning opportunities associated with active tectonic examination of large population centers.
