Curated OER
Measurement of the Depth of the Ocean
Students comprehend the physical properties of pressure and Boyle's Law by designing a depth gauge. They construct a capillary depth gauge and calculate the calibrated depth marks of the capillary tube. They determine the margin of error...

Frozen Water Before? I'm Sure You Have; But I Bed You've Never Frozen Salt Water! Water!!
High schoolers examine what happens to salt water when it freezes. In groups, they measure density and salt concentrations in different samples of water and record its freezing time. They discuss the relationship between water density...
Curated OER
Where Have All the Road Salts Gone, Long Time Migrating
Students examine what happens to road salt after it is applied to the road during a storm. In groups, they collect their samples using a conductivity meter and enter their data into a database. They analyze and discuss the data...
Curated OER
The Magnetic Sun
Students follow steps to build a simple version of a magnetometer, an instrument capable of detecting areas of strong magnetic field. Students use the magnetometer to investigate models of the Sun and examine images of the Sun.
Curated OER
Weightlessness Demonstration
Students investigate gravity. In this weightless lesson plan students complete a lab activity about how a free fall might effect how one perceives gravity.
Curated OER
Worms in a Bottle
Young scholars gain a better understanding of the worm and its role in the recycling of organic materials into simpler forms by constructing worm bottles and observing for 60 to 90 days.
Curated OER
In Search of Cosmic Rays
Students compare rates to altitude. They conduct a class discussion about the results.
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
Physical Habitat of a Stream
Students 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
Students analyze the relationship between soil moisture and its effect on soil temperature.
Curated OER
Up, Up and Away
Tenth graders experiment with gravity and air pressure. In this geometry lesson, 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 a...
Curated OER
Keep Your Eye on the Sky
Young scholars examine the different types of satellites, cloud formations and weather patterns. In this weather lesson plan students use the Internet to research weather satellites, then write an article and create graphs.
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
The Case of the Mysterious Red Light
Students investigate why some sunrises and sunsets are unusually bright red.
Curated OER
Constructing a Spectroscope
Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
