Curated OER
Electrons and Atoms
For this atoms worksheet, students determine the velocity, wavelength, power, and frequency of given atoms. Student describe wave-particle duality and give the principle and angular quantum numbers for given orbitals. This worksheet has...
Curated OER
What is the Electromagnetic Spectrum?
In this electromagnetic spectrum worksheet, students will brainstorm a main idea about this spectrum and then write in 3 supporting details. This worksheet is a graphic organizer.
Curated OER
Measuring the Speed of a Wave
Young scholars create an experiment in which they measure the speed of a wave and record the data in a graph. They work in small groups to write the procedure for the experiment and share it with another group for cross checking of the...
Curated OER
Wavelength And Resolution
Students perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...
Curated OER
Looking at the World in a Different Light
In this activity, 7th graders relate colors to wavelengths of light; explain how we see colors and describe types of waves and their technological applications. Students go through a tour and answers questions to the quiz as they go...
Curated OER
Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
Curated OER
Lesson- Colors of Stars
Student describes what happens to the color of a stove burner or a coal as it gets hotter. They use the applet to determine what range of temperatures range give you a red light, what range of temperatures would give you a white light,...
Curated OER
Spectrophotometry Lab
Students use a machine called a spectrophotometer to determine how much light is absorbed by certain substances. Students record the absorbance and the % of light transmitted for different color solutions, graph their results, and then...
Curated OER
Wavelength and Energy
Pupils using a rope and other materials explore wavelengths and frequency. If time permits, more experiments can be tried.
Curated OER
Colors of the Sky
Students examine what causes the different colors of the sky. They conduct an experiment replicating the earth's atmosphere and wavelengths.
