Great Students at Ensor Middle

I would like to Thank all of my students for being such great students and I will miss all of you! I am only leaving Ensor Middle School due to a promotion. Keep up the great work and do your best to continuing to prepare for your 8th grade Science TAKS!!! Remember, that all of you are scientists and continue to do your best!!! I would like to see each of you succeed and do your best at all times. Take care! ---Mrs. B. Bumpas

Phases of the Moon - Project

Phases of the Moon Project – Mrs. Bumpas

The Task: Build a 3-dimensional edible model of the Lunar Cycle that illustrates all of the 8 phases of the moon. Your model should have the following characteristics.

• Phases of the Moon need to be named and labeled
  
• Show the 3-D nature of the Phases of the Moon and they have to be shaded representing each shade. Be able to name the 8 phases of the moon when asked.
  
• You will receive a project grade for the science project.
  
  This project is not meant to have you go out and purchase expensive materials to build your Phases of the Moon Project. Please use inexpensive materials you have at home. Edible projects are allowed!
  
  *** Your project can be made of the following examples: cup cakes, cookies, cake, brownies, and any other food that is edible.
  
  Project Due: A Day classes are due on Monday, December 14, 2009.
  B Day class projects are due Friday, December 11, 2009.

Topic: Class Notes Wave Properties - Dec. 4 &7, 2009

• Topic: Wave Properties
  
  
  Notes
  
  Amplitude:
  


• of a transverse wave is one-half the distance between a crest and a trough.
  


• of a compression wave is greater when the particles of the medium are squeezed closer together in each compression and spread farther apart in each rarefaction.
  


• the greater the amplitude the greater the energy.
  Example: tsunami and hurricane waves
  
  
  
  Wavelength:
  


• of a transverse wave is the distance from the top of one crest to the top of the next crest, or from the bottom of one trough to the next.
  


• of a compressional wave is the distance from the center of a compression and the center of the next or from the center of one rarefaction to the center of the next.
  
  
  
  Frequency:
  


• of a wave is the number of wavelengths that pass a given point in 1second.
  the unit of frequency is the number of wavelengths per second, or hertz (Hz).
  the faster the vibration the higher the frequency.
  
  
  
  Graphing waves
  Frequency and wavelength are related.
  


• longer wavelengths result in smaller frequencies.
  


• larger frequencies results in shorter wavelengths.
  
  
  
  
  Speed of waves:
  


• mechanical waves travel faster in medium in which the atoms are closer (solid, liquid, gas)
  


• electromagnetic waves travel faster through gasses than in solids and liquids.
  
  
  
  *****Light waves travel much faster than sound waves.

Topic: Class Notes- Electromagnetic Waves Dec. 4 & 7, 2009

• Topic: Electromagnetic Waves
  
  
  Notes
  
  Electromagnetic waves are waves that do not require matter to carry energy.
  Transverse waves
  
• Produced by the motion of electrically charged particles.
  
• Can travel through medium such as a solid, liquid, or gas.
  
• Can travel through outer space or in a vacuum where no matter exists.
  
  
  
  Long wavelength – low frequency
  Examples: Radio, microwave, infrared
  
  
  Short wavelength – high frequency
  Examples: visible light, ultraviolet, x-rays, gamma rays

1. Students will type out the website and complete all of 17 interactive lessons as a team.
2. Students will summarize in 2 or more sentences what was learned from each activity.
3. They must also list the topic in the summary and number them in the order of the website.

Waves Class Notes- Nov. 30-Dec. 1, 2009

Topic: Waves


Class Notes



Waves are rhythmic disturbances that carry energy without carrying matter.



Mechanical waves are waves which use matter to transfer energy.



A medium is matter through which a mechanical wave travels. Solids, liquids, gasses. Energy is transferred from particle to particle in the medium. Example: a ripple in the pond –water is the medium.




There are two types of mechanical waves:
1.Transverse Waves
2.Compressional Waves (also called longitudinal waves)


Longitudinal and Transverse Wave Motion


In transverse waves:
The energy causes the matter in the medium to move up and down or back and forth to the direction the wave moves. (Perpendicular)
the vibrations move at right angles
the peaks are called crests, and the valleys are called troughs.
Example: ocean waves




Longitudinal and Transverse Wave Motion
In compressional/longitudinal waves:
the matter in the medium moves forward and backward in the same direction that the wave travels.
the energy travels in the direction of the wave, but the medium does not travel.
The vibrations move in the direction of wave movement.
Example: sound waves




Compressions are when molecules in the wave are squeezed together.



Rarefactions are when molecules have more room and move away from each other.
