Curated OER
In Search of Cosmic Rays
Students compare rates to altitude. They conduct a class discussion about the results.
Curated OER
Geologic Time: Relative and Absolute Dating
Students investigate relative and absolute dating; determine the difference between the two dating systems; and apply this knowledge by creating a geologic timetable of their own.
Curated OER
The Water Cycle
Students create an "animated" water cycle wheel that illustrates where water comes from and where it goes.
Curated OER
Do Human Practices Affect Water Quality?
Students determine if human practices have any noticeable effects on the quality of stream life as measured by the presence of certain macroinvertebrates. They collect, preserve and identify macroinvertibrate samples and quantify the data.
Curated OER
Life in Streams and Ponds
Students collect microorganisms, demonstrate correct laboratory/Gram stain procedure, and design and construct tables to organize data.
Curated OER
An Investigation into Effects of Rhizobium Soil Bacteria on Nitrogen Availability
Students identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.
Curated OER
Physical Habitat of a Stream
Learners measure in metric units and use a stopwatch, calculator. They collect data with minimal instructions after the initial pre-activity briefing, then record data in the data sheets provided.
Curated OER
The Effect of Moisture on Soil Temperature
Young scholars analyze the relationship between soil moisture and its effect on soil temperature.
Curated OER
Milestones of Flight
Students identify significant milestones in the history of flight. In this aviation history activity, students study various resource materials and construct timelines of significant achievements.
Curated OER
Up, Up and Away
Tenth graders experiment with gravity and air pressure. In this geometry activity, 10th graders build their own kits and fly it. They investigate the questions: what keeps a kite in the air and what are some important factors when flying...
Curated OER
Trends of Snow Cover and Temperature in Alaska
Learners compare NASA satellite data observations with student surface measurements of snow cover and temperature. They practice data collection, data correlations, and making scientific predictions.
Curated OER
Understanding the Indoor Environment
Pupils create and deliver speeches about why their school should have an Indoor Air Quality team. In this speeches lesson plan, students make presentations to school board members about having an IAQ team.
Curated OER
Understanding the Indoor Environment: Vocabulary Development
Pupils acquire new vocabulary by reading an assigned text and determining the meanings of unfamiliar words. In this vocabulary development lesson, students acquire strategies to use in a small group as they decode meanings of...
Curated OER
Vocabulary Development Vocabulary Zoo
Students practice their vocabulary skills. In this vocabulary skills lesson, students recall vocabulary words regarding indoor air quality.
Curated OER
The Lake Effect
Fourth graders conduct an experiment demonstrating the effects of water and air temperature on precipitation. They create graphs demonstrating their findings using Claris Works for Kids.
Curated OER
Principles Of Flight: Wings That Spin
Students discover how flight is possible. In this physics lesson, students investigate the properties of a blimp and gyro-copter, comparing rotating wings and fixed wings of aircraft. Students create their own model aircraft...
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
Weather Patterns
Pupils use yearly averages over a five-year period to understand weather trends for a specific area.
Curated OER
The Case of the Mysterious Red Light
Pupils investigate why some sunrises and sunsets are unusually bright red.
Curated OER
Constructing a Spectroscope
Pupils construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
