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 interactive activity demonstrates and provides explanation for how acid rain affects aquatic ecosystems and how certain species react to decreased water quality as pH becomes lower. The activity also explains the pH scale as a measure of acidity.

In this lesson, students will identitfy several forms of acid precipitation. They will list effects of acid precipitaiton and explain the actions that cause the damage. Students will define "buffering" and explain how environmental factors can act as buffers.

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.

In this chemistry field lab, students will determine the density, pH and water content of 4 types of soil; 1) prairie soil, 2) transition soil, (where the prairie meets the trees) 3) woods soil, and 4) riverbed soil at various locations in and around the Fergus Falls area. Students will compare class data and write a lab report describing their results. A detailed lab report format will be provided. Students will also analyze their findings and report on the various differences and similarities found in their soil samples.

Students will be able to design and defend a salmon rearing tank for the highest survival rate. They will measure temperature, ph and ammonia on daily basis and make needed adjustments. Given unit ending data students will be able to determine the optimal design for a salmon rearing tank using patterns between water conditions and survival rates.

Student teams locate a contaminant spill in a hypothetical site by measuring the pH of soil samples. Then they predict the direction of groundwater flow using mathematical modeling. They also use the engineering design process to come up with alternative treatments for the contaminated water.

In this chemistry lab activity, students will apply what they learned from titrating and graphing a strong acid (HCl) with a strong base (NaOH) to a titration involving a strong base and a weak acid. Before performing the titration students will be asked to predict how the end point of the titration will shift. They will collect data and graph it in the same way they did in the earlier titration, determine the end point, and note how it shifted. Finally they will be asked to apply their understanding of the definitions of "strong" and "weak" as applied to acids and bases to explain the observed shift. Students will produce an informal lab report that includes a prediction, data table, graph, and analysis.

This unit includes 10 lessons that culminate in a student created final product presentation on the factors that influence climate change through the lens of chemistry and oceanography using literacy strategies to conduct inquiry level research. Using inquiry-based reading, student will examine an anchor text to formulate a question to guide their research and development of student driven projects. Throughout the unit, students will use a variety of texts, websites, and other resources to develop a product and presentation that exhibits their literacy and inquiry skills. Using inquiry-based reading, students will explore an anchor text and then develop their own essential and supporting questions to guide their research. Over the course of the unit, students will explore a variety of texts and grow in their knowledge of cellular organelles and in their ability to use informational text to support their inquiry and research.

This interactive resource is a set of eight virtual labs that help students learn basic laboratory techniques and practice methods used by lab technicians and researchers in a variety of careers, using specific food science lab processes.

In this activity, students take water samples from a local waterway. They will test the pH and then conduct a series of experiments to investigate the chemistry of the water.

In this lesson, students will conduct a simple experiment to test what the ph of water may be when certain solids are added to the water and relate this to the effects of acid mine drainage.
