Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
Young scholars experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
Curated OER
Earth's Weather
Seventh graders learn how solar radiation, latitude, and other factors affect weather. They break into six groups and are assigned a topic to research and to present their findings orally.

Daisyworld: Interactive On-line PC and Mac
Students use a JAVA interface to explore the Daisy World model to illustrate a mechanism through which - according to the Gaian hypothesis - biota might optimize their abiotic environment by means of negative feedback.
Curated OER
"Space" Investigations
Sixth graders understand the patterns of change observable on Earth as a result of the movement of the different bodies in the solar system. They identify the physical characteristics of the different components of the solar system.
Curated OER
Measuring Temperature
Young scholars explore the different variables that affect surface temperature. They study how temperatures can vary widely within close proximity due to variables such as surface, directness of sunlight, and distance from buildings.
Curated OER
Wet Weather, Wet Climate
Pupils discover the differences between weather and climate in this long-term lesson introduction. They create rain gauges and practice reading rainfall measurements, view a website showing the cloud cover in their location and draw bar...

Statistics and Probility
Seventh graders collect data and make predictions. For this geometry lesson, 7th graders work in tiers collecting data and plotting it. They make inferences and predictions about their collected data.
Curated OER
SkyHighScrapers
Students investigate quadratic functions. In this Algebra I/Algebra II lesson, students determine the equation of a quadratic function that closely matches a set of points. Students investigate the necessary information that would...

Primate Characteristics and Exaptation
Students compare the features of gorilla to humans. For this biology lesson, students simulate adaptation using materials found in the classroom. They explain what exaptation means.
