Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
Curated OER
Diffraction of Laser Light, Polarization and Color Filters
High schoolers investigate light behavior by conducting a series of experiments. In this physics lesson, students calculate the wavelength of the light source using an equation. They determine what color is produced when light of...
Curated OER
Adding Trigonometric Functions
Students identify trigonometric functions. In this trigonometry lesson, students add and subtract trigonometric functions. They add sine and cosine waves and relate it to the real world.
Curated OER
Indinite Potential Well
Students use experiments such as electron diffraction that show that particle have a wavelike nature. When they are fired through a thin slit, rather than scattering like hard spheres they interfere like waves. Students see that the...

Powers of Ten with the Blue Morpho Butterfly
Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.
Curated OER
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...

Recording Electricity in the Brain
In this electricity in the brain worksheet, students read about neurons, electrical impulses, brain activity and EEGs that measure electrical activity in the brain. They answer four critical thinking questions about brain activity.
Curated OER
Solar Storms-Fractions and Percentages
In this solar storms activity, students find the percentage of X-Flares and Halo CMEs that occurred in solar storms and complete a Venn Diagram comparing the numbers of each.
Curated OER
Water Quality
Students analyze water quality and turbidity of collected samples. In this physics lesson, students conduct tests to identify the suspended particles in the samples. They explain how human activities affect water quality.
Curated OER
Uncovering a Signal
Pupils examine information EEG impulse control. They observe representations of EEG signals. Students use inquiry skills to interpret and analyze the waveforms. They explore how confusion can send control impulses to the wrong...
