Curated OER
Luminous Efficacy (Efficiency)
Students examine the basics of luminous efficacy and why it is used. In this light source lesson students test energy efficiency and the luminous efficiency for babies.
Curated OER
An Overview of Solar Radiation
Students examine the Stefan-Boltzmann Law. Students compute basic radiative "constants" of the sun-Earth-atomosphere system. They examine the wavelength of maximum radiation emission.
Curated OER
Climate And the Greenhouse Effect
Students demonstrate the greenhouse effect. They recognize that relatively small changes to our environment can stimulate significant climate changes. They determine that the "scientific method" is a process of testing hypotheses and...

AP Chemistry Atomic Structure-7 Worksheet
In this atomic structure worksheet, students solve twelve problems related to wavelength, frequency, electron transitions, emission spectra and quantum number.
Curated OER
Physics- global warming
Young scholars discuss the concept of global warming and view a multimedia clip on the global warming phenomenon. They statistically analyze mean temperature data and compare a given set of data. Data on atmospheric CO2 is done then...
Curated OER
You, Me and UV
Students explore the validity of claims of UV protection. Students research UV rays and the cancer danger presented by these rays. Working in groups, they perform tests on sunglass and sunscreen products to determine if their claim of UV...
Curated OER
The Universe in a Different Light
Pupils become aware of some of the objects studied in, and concepts associated with, high-energy astronomy. They do this by participating in card games that teach and review these concepts.
Curated OER
Day and Night
Students using experiments try to demonstrate how observations can be affected by the cycles of night and day.
Curated OER
Wavelength and Energy
Students using a rope and other materials explore wavelengths and frequency. If time permits, more experiments can be tried.
Curated OER
It's All In The Surface: The Effects Of Color & Texture On The Ability Of A Surface To Absorb Solar Energy
Ninth graders examine how dark surfaces absorb more light than light surfaces. They perform an experiment that compares various surfaces abilities to absorb heat, then record and analyze the results.
Curated OER
Seeing The Sun In A New Light
High schoolers examine the observation of "coronal holes," by x-rays, also about related fast streams and moderate magnetic storms that recur at 27 day intervals. They study NASA'S great observatories.
Curated OER
Color Recognition
Young scholars envision how space observatories make use of monochromatic filters to collect data on the color of objects in space. They see the actual colors of objects when they are in monochromatic light.
Curated OER
Twisted Vision
Students explain polarization vision and why some animals have it while others do not. They examine the reasons why it would be helpful for marine organisms to have polarized light.
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
Star Power! Discovering the Power of Sunlight
Students estimate the energy output of the sun. They estimate how much power sunlight the sunlight provides to the earth. They build a simple device to measure the amount of solar radiation the earth receives from the sun.
Curated OER
The AM Radio: An Exploration of Communication Using Radio Waves
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...
Curated OER
Naturally Magnetic Elements
Students explore naturally magnetic elements. In this magnets lesson, students examine the periodic table of elements. Students discover the parts of an atom and determine which three elements are magnetic.
Curated OER
Honors Chemistry I
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.
Curated OER
(S-4) The Many Colors of Sunlight
High schoolers observe and explore the characteristics of light.
Curated OER
Popcorn Science
Pupils 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. Students...
Curated OER
Reflect and Refract
Pupils explore light. In this properties of light lesson, students define the terms refract, reflect, and diffract after listening to the teacher's description. Pupils listen to the book Light Magic and observe a spoon in a glass of...
Curated OER
Lenses
Students explore vision by experimenting with lenses in equipment. In this optics lesson, students define the different technology that enhances vision such as microscopes, telescopes and cameras. Students experiment with these devices...
