Curated OER
Teaching about Increased Conductivity: Are Culverts The Culprits?
Students encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.
Curated OER
Biochemical Cycles: Recycling Carbon and Nitrogen
Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.
Curated OER
Weather Lesson 1
Students describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere. They also explain what causes the atmosphere to heat up in some places more than in others.
Curated OER
Teaching about the Effect of pH on Aquatic Organisms
Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.
Curated OER
Cycles Review
Eighth graders discuss the four major cycles of matter. In this general science lesson, 8th graders decide which of the four is the most important. They share their opinion in class.
Curated OER
Teaching about Data Interpretation
Students explore a variety of relevant lake water chemistry questions, compose responses, and present their results in a poster format. They, in pairs, answer questions about lake chemistry which are imbedded in this plan.
Curated OER
Biological Sciences
Students examine biodiversity and interrelatedness concepts. In this ecology lesson students go on a field trip and fill out a data sheet.
NorthEast Ohio Geoscience Education Outreach
Carbon Cycle
Using a jigsaw approach, earth science experts teach each other about the physical, biological, and geologic components of the carbon cycle, with a specific focus on the ocean.
Curated OER
Plant Structure, Function and Growth
Students study three structures of a plant as well as their locations and functions. In this botany lesson students complete several activities on plant organs and their functions.
Curated OER
Plant Classfications
Seventh graders observe and discuss as a class the different types of vascular plants. They examine the different parts of the plant and some of the processes occurring in plants with activities accompanying.
Curated OER
Diurnal Cycling Experiments
Pupils carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...
Curated OER
Oxygen Factory
Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.
Curated OER
Science Processes
Fifth graders observe a dry piece of bread and a damp piece of bread in two separate sealed bags that have been sitting for several days that have been labeled. The observe the mold with a hand lens and record findings in their science...
Curated OER
Water Quality and Dissolved Oxygen
Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.
Curated OER
Earth's Atmosphere and Temperature
Learners explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...
Curated OER
Monitoring Oxygen Level
Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.
Curated OER
The Global Impact of Insect Borne Diseases & Agriculture
Students study the global impact of insect borne diseases, the appropriate use of pesticides, and the concept of human interrelations on a world wide scale. They examine how to safely apply a pesticide, according to the label.
Curated OER
Dissolved Oxygen Lesson
Pupils investigate what dissolved oxygen is and why it is important to aquatic life and what factors influence levels of dissolved oxygen in a lake. They study how to use MS Excel to make charts to show trends and correlations.
Curated OER
The Biological Carbon Cycle
Students learn about the biological carbon cycle. In this carbon cycle activity, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during this cycle.
Curated OER
Water Quality Monitoring
Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
Curated OER
Primary Producers
Students examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of phytoplankton...
Curated OER
Teaching about the Chemistry of Oxygen Solubility
Learners explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.
Curated OER
Smog Be Gone
Students begin the lesson by identifying greenhouse gases. In groups, they observe and record the effect of the gases on the atmosphere and the temperature of the Earth. They participate in activities that describe the role of...
Curated OER
Sustaining Life Under the Ice
Students design and conduct experiments in order to identify the components of lake water environments that are affected by winter ice cover. They use the experiment results to propose effective human management of these ecosystems.
