Physical Characteristics of the Troposphere

Students identify the factors affecting friction. For this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.

Not quite a star, not quite a planet ... what are brown dwarfs? Young astronomers learn the peculiarities of these heavenly bodies through a short video. The narrator explains the characteristics of brown dwarfs and the different types....

More of a math lesson than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and cohesive....

Physics masters figure out the wavelength of different waves. Looking at a wave graph, they identify different characteristics. Many more problems get them working with both electromagnetic and sound waves. There are a total of 17...

Need some information on the brown-throated three-toed sloth? In this reference guide learn all about the sloth's unique characteristics, physical characteristics, habitat, diet, and much more!

Determine the wavelength and amplitude of a wave based on the vertical position vs. horizontal position graph.

Determine the period, frequency and amplitude of the wave that produced the position vs. time graph shown below.

Two wave graphs depicting a sine wave and relating the various characteristics (wavelength, amplitude, frequency, and period) of a wave to each other. The site includes an interactive JavaScript form in which the visitor enters one...

In this simulation an object is attached to two strings under tension on opposite sides of it. The object's starting position and the strings' lengths can be altered. The path of the object when it is released is traced on an...

Learners explore the science of sound by considering the characteristics that make unique sounds. Through an interactive simulation, they adjust tension and string size and view the corresponding wavelength and amplitude changes.
