The calculator has an interesting way of displaying numbers in scientific notation, but don't let that confuse your pupils! A lesson designed to give learners practice with scientific notation and calculators provides several practice...

Why do soybean plants that are planted weeks apart in the spring mature simultaneously in the fall? Four independent activities cover the history of phytochrome research, scientist collaboration, the electromagnetic spectrum, and...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...

Take a look with another perspective. Pupils read to find out what portion of the electromagnetic spectrum a space telescope sees and the difficulties of viewing infrared radiation from other objects in space. Individuals discover how...

The universe is full of a mystic matter people cannot see. Pupils respond to 10 questions about the stuff in the universe. Most of the questions involve the big bang theory and dark matter. Learners find out how astronomers have found...

It takes 225 million years for our sun to travel around the galaxy. The presentation covers astronomical units, light years, telescopes, types of stars, the life cycle of a star, and types of galaxies. This is the last lesson in a...

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Take a stretch, but don't wave goodbye. An interesting resource provides everything needed to present an introductory lesson plan on waves. Teachers present a PowerPoint defining the types of waves and their characteristics. Pupils use a...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Challenge your young readers with a passage about physical science. After reading about sound waves and electric currents, kids answer five reading comprehension questions about what they have read.

[Free Registration/Login may be required to access all resource tools.] In the following tutorial students will describe the relationships between speed, wavelength, and frequency of light. They will understand the photoelectric effect...

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

Manipulate the incident angle, color of light, wavelength, and medium to see how the refracted angle is affected.

This analogy story explains the manner in which the wavelength of light affects the maximum resolution of a microscope.

[Free Registration/Login Required] Neon lights are a type of discharge tube. Observe how electrons create colored light in a hydrogen gas discharge tube. Can you figure out why hydrogen's emission spectrum contains more than one color of...

Determine the wavelength, in nanometers, of light emitted from an atom.

This lab is designed to allow students to look at the relative proportions of different wavelengths of light that are emitted by stars at different temperatures.

[Free Registration/Login may be required to access all resource tools.] The speed of electromagnetic waves, their wavelengths and frequencies and how to calculate wavelength or wave frequency.

This lab is designed to have students investigate the relationship between the speed of a wave, the frequency of the wave and the wavelength of the wave. Students can vary wave speed and frequency. Each of these should be varied while...
