Students examine stoichiometry. In this chemical reaction and mole lesson, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

For this petroleum products worksheet, students are given the components of crude oil and they graph the various products found in a 50 gallon barrel. Students complete an activity to determine if they have collected cards that represent...

Nitrogen is an essential element for productive farming. An interactive lesson explores the chemical makeup of different fertilizers and their corresponding nitrogen content. The interactive challenges individuals to complete...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Learners read and discuss decomposers and how they affect the environment. In this decomposers lesson plan, students also discuss how engineers use decomposers to help the environment.

Knowing what farmers are feeding livestock is just smart business. A WebQuest lesson helps learners build an understanding of the relationship between amino acids, nitrogen, and protein. With interactive instruction,...

Students consider the role of industry on the American landscape from a variety of perspectives. They investigate a simulated case study. They investigate a chemical spill catastrophe. Students write an informative pamphlet to assist...

Middle schoolers describe factors that affect the solubility of a chemical substance in seawater. In this sea environment lesson, student explain how information on the solubility of a substance can be used to measure water currents....

Students explore how a cow digests the grass they eat. In this science/math lesson, students compare the quality of forage. Additionally, students determine the effects of rangeland health on the production.

This lesson is a compilation of interdisciplinary, technology-infused activities that focus on the often complicated and sometimes controversial issues related to toxic chemicals in children's environment. Special emphasis is placed on...

Students examine how to calculate the part-per-million and part-per-billion units used to measure contaminant concentrations in the environment. They calculate ratios, take a quiz, analyze a sample chemical spill, and determine if...

Students apply a data set to create a graph show how iron ore impacts an ecosystem. They explain how the iron effects the distribution and abundance of phytoplankton in coastal ecosystems using spreadsheet software.

First graders identify forms of pollution and describe effects that various pollutants can have on people, wildlife, and plants; students describe relationships between various forms of pollution and human actions.

Fourth graders experiment to see which objects decompose. In this compost instructional activity, 4th graders observe the changes of labeled objects in a bag. Leave the objects for one month and record the changes by observation and...

Eighth graders visit the Virtual Earthquake Web site and complete activities that demonstrate how geologists locate the epicenters of earthquakes. The site uses actual data from historic earthquakes.

Middle schoolers measure the pH of soil samples from a hypothetical site to locate a contaminant spill and will predict the direction of groundwater flow using mathematical modeling. They use the engineering design process to develop...
