Super Gelatin
Students investigate the refraction properties of gelatin to calculate its index of refraction. They discover that as the light travels through the gelatin, its speed and wavelength also change. Students find th indes of refraction of an...
Curated OER
Diffraction of Laser Light, Polarization and Color Filters
Students investigate light behavior by conducting a series of experiments. In this physics lesson plan, students calculate the wavelength of the light source using an equation. They determine what color is produced when light of...

Justice Demands an End to Segregation, But it Does Not End
Learners define human rights and describe how it applies to politics, economics and cultural rights. As a class, they watch a video how the Constitution was made and discuss its purpose. In groups, they present information to the class...
Curated OER
Phase Change
Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...
Curated OER
Fundamental Properties of a Wave
Students investigate the form and motion of a wave, and examine the fundamental properties of wavelength, frequency, and amplitude. They discuss the fundamental properties of a wave, and in small groups conduct an experiment involving...
Curated OER
Displacement, Velocity, Acceleration
Twelfth graders solve problems of displacement, velocity and acceleration. In this calculus lesson, 12th graders are given the acceleration and asked to derive the formula for velocity. They work problems involving real life scenarios.
Curated OER
Religion in Public Schools
Students examine the presence of religion in public institutions. In this ethics instructional activity, students focus on one aspect of the presence of religion in public institutions, and the controversy surrounding religion in the...
Curated OER
Carrying Capacity of Ecosystems
Students define population and carrying. In this algebra instructional activity, students explore exponential growth and decay based on animals and things that grow or decrease exponentially. They graph their findings and discuss their...
Curated OER
Electromagnetic and Physical Waves
Learners compare and contrast electromagnetic and physical waves. For this wave lesson, students discover that all waves reflect, refract, and diffract energy. Learners work in small groups to experiment with waves and evaluate the type...
Curated OER
Human Population's Response to Re-emerging and Emerging Infectious Diseases
Students examine the human population response to microbial diseases. For this disease lesson students observe population trends, write about a scientist and evaluate and defend current treatments for infectious diseases.

DNA: What Does It Mean?
Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.
Curated OER
Infrared Remote Controllers
Students differentiate the two types of remote controllers namely RF and IR. In this technology lesson plan, students test their properties using CEENBoT and Isobot. They present their findings in class.
Curated OER
Examining the African American Family through the Eyes of Women Authors
Pupils read stories by women authors on the characteristics of the African-American family. Using the internet, they research the history of issues that have affected African-American families from the Civil War to the Civil Rights...
Curated OER
How Do The Colors of Light Mix?
High schoolers investigate the mixing of light. They form a hypotheses to reason why color changes occur and they write conclusions and ask new questions arising from the investigation. Students identify the primary and complementary...
Curated OER
How Germs Spread
Fourth graders investigate how germs spread in this lesson. They listen to "The Flea's Sneeze" by Lynn Downey and make predictions on why the hog began sneezing. They then conduct an experiment using flour and paper cups demonstrating...
