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
Dissolved Oxygen Lesson
Students 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.

What Do Plants Need?
Students experiment with plants. In this plant lesson, students research the needs of plants. Students determine if all plants have the same requirements for growth. In small groups, students experiment with different plants.
Curated OER
Making Community Measurements: Which Plant Part?
Learners identify a plant in a given community and make a variety of measurements. They determine how a plant meets its basic needs. In addition to identifying plant parts, they observe seasonal change and compare plants within a community.
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
Diurnal Cycling Experiments
Students 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...

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
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
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
The Biological Carbon Cycle
Young scholars learn about the biological carbon cycle. In this carbon cycle lesson, 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
Learners 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
Students 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 instructional activity 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...
