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.

Students examine the components that are used to make a primitive AM radio. In circuit and radio construction students often are asked to assemble parts are or what function they perform. They examine each main component on an individual...

In this honor chemistry I worksheet, students use all available resources to answer each question given. Students apply their knowledge of light, quantum theory of light, Bohr's model, photoelectric theory.

Students observe and explore the characteristics of light.

Students identify and apply the scientific method through an experiment with popcorn. Then they identify what independent, dependent, and control variables are and create a list of different variables that affect popcorn popping....

In this stars worksheet, students review what makes up a star, how astronomers learn about stars, and the different types of stars including low mass and high mass stars. This worksheet has 62 fill in the blank statements.

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

This lesson focuses on investigating the electromagnetic spectrum using ultraviolet beads. Students learn how material properties change as the size of the material decreases to the nanoscale.

A very lengthy page from friesian.com discussing Bohr's theory of electronic energy levels and the explanation of commonly observed atomic emission line spectra. The concept of a photon and Einstein's observation of the photoelectric...

A discussion of the Advanced Light Source (ALS) facility and its use in material analysis and medicine.

The sun's energy is the primary source of energy for all surface phenomena and life on Earth. Combined with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this...
