Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

Finally, an electromagnetic spectrum lab that will get glowing reviews from your class! Explore the nature of light using red and blue LED sources and fantastic phosphorescent paper. Young scientists compare the effects of blue light...

In the study of wind energy, scholars build a small windmill and observe how it transfers wind into mechanical energy. Learners will make connections to the previous lesson with concepts such as the creation of wind...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Bubbles aren't just for children. In the third installment of a seven-part series, teenagers use bubble solution to create bubbles and observe patterns of refraction on the bubble surfaces. Application of this concept to thin films in...

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion...
