Intervention Questions Chapters 31-35 write Q & A Why doesn’t Stanley fight back when Zigzag taunts him? What would you do in his position? Why doesn’t Stanley go after Zero? 3. Thinking about Zero, “what worried [Stanley] the most . . . Was the fear that it wasn’t too late.” What does this mean? 4. Does Stanley approach his predicament intelligently? Is his logic sound? What would you do in the same situation? 5. When Stanley sees Big Thumb, “[H]e kept walking toward it,although he didn’t know why.” Why do you think Stanley keeps going?

Intervention Closure 11/14/16 Stanley has always blamed someone else for his bad luck. Now Stanley feels very guilty about not searching for Zero. Why do you think he feels this way? What does this suggest about Stanley? Write a one paragraph response in proper paragraph format.

Properties of Waves Energy in Motion!!! GLECompare and contrast the basic parts of a wave. GLEInvestigate the types and fundamental properties of waves.

What do these objects have in common?

What is a wave? A wave is a moving vibration that transfers energy through matter or space. 2 types of Waves Mechanical waves are transmitted through a medium, such as air or water. The energy of the wave causes the medium to vibrate. If there is no medium, as is the case in outer space, a mechanical wave will stop moving. Mechanical waves can be either transverse or longitudinal. Electromagnetic waves can transfer energy through both a medium and empty space. Light is an electromagnetic wave. Only transverse

Transverse Particles vibrates perpendicular (at right angles) to the wave travel Electromagnetic & Mechanical

Transverse Wave

Transverse Wave Vocabulary Crest—a crest is the highest point of a transverse wave Trough—a trough is the lowest point of a transverse wave Wavelength—the distance between one wave crest and the next (or between one wave trough and the next). Amplitude—the size of the displacement or change caused by the wave. The distance from the rest position to either the crest of trough of the wave.

Longitudinal Particles vibrates parallel to (in the same direction of) wave travel Example sound waves

Longitudinal Wave

Longitudinal Waves Vocabulary Compression—the area of a longitudinal wave in which the molecules are the most crowded together. Rarefaction—the area of a longitudinal wave in which the molecules are the most spread apart Wavelength—the distance from one point of compression to the next on a longitudinal wave

Other Vocabulary Medium- a physical environment in which a wave travels through Wave Speed- how fast a wave is traveling Wave frequency- the number of wave crests that pass by a point each second; measured in hertz

Longitudinal Use your Slinky to demonstrate a longitudinal wave: Work with a partner Stretch it out along the table One of you grasp and draw several coils of a stretched Slinky toward yourself Release the coils The other student must hold his or her end of the Slinky still A longitudinal wave pulse will be generated and travel down the length of the Slinky.
