Wednesday, Nov. 12 th (A day) Thursday, Nov. 13 th (B day) Science Class
List 5 observations can you make by looking at this picture? Warm updraw this picture in your notebook
Volunteers to share with the class
An object splashed into the water, creating 11 waves The water appears to be moving The waves are moving out from 1 center circle The rings look bigger as you move out from the center The waves appear to be equally spaced apart I can infer an object was thrown into the water; the object sank because it was more dense than the water My observations.
Review Test. Take your test home and get it signed for 5 extra points This must be returned to me Monday to receive these 5 points
Interactive notebook Find the next blank page in your notebook We are starting our next unit label the page 6.P.1.1 Forces and Motion (introduction to waves) Add this to your table of contents Where is this standard in our classroom?
6.P.1.1 Forces and Motion Our next objective: Compare the properties of waves to the wavelike property of energy in earthquakes, light and sound (we are going to investigate (how energy travels in seismic waves (earthquakes), light waves and sound waves)
Vocabulary Waves Demonstrate to the class: Label page Go to the next empty page in your notebook Draw a line vertically through the center of the page (demo) Draw 2 lines horizontally across the page Now repeat this on another empty page in your notebook On these 2 pages in your notebook, you should have 12 equally spaced boxes!
Number your boxes Beginning on the first page, number from 1-6 On the next page, number from 7-12
Rotation around the room You will count off from 1 -12 You will start in the station that matches the number you counted off You will have 18 minutes to rotate around the room to record all 12 vocabulary words Rotate at your own pace but remember if you are not finished will have to visit the wiki page for homework to get any remaining definitions GO!
Wave Video Discovery Ed: The Basics: Waves, Light and Sound
Wave Characteristics Waves are moving energy All waves transmit energy, but not matter, from one place to another. Waves move at different speeds Waves move through different materials known as mediums Write EVERYTHING on this slide
Vibrations Waves are created when a force creates a vibration These vibrations transfer or spread the energy away from the force Write EVERYTHING on this slide
Our Discussion Image: In the image: What is the medium? The water What do you think caused this vibration force? A rock splashing into water
Waves, Energy and Vibrations Energy will cause materials to vibrate(move back and forth); the energy moves along in a wave-like manner Write EVERYTHING on this slide
Wave Videos Brain Pop: Waves
Wave Behavior Described by how fast the energy moves or spreads out The distance between each wave (wavelength) How do you think a wave with lots of energy will travel? Fast or slow and why? Write EVERYTHING on this slide
Wave Categories 2 Basic Categories of Waves: Mechanical Waves: requires a medium in which to move the energy along (add these examples to your vocabulary word: ocean, seismic, sound, and slinky waves) Electromagnetic Waves: does not require a medium (can travel through empty space known as a vacuum = area of no matter) (add these examples to your vocabulary word: light and radio waves) Write EVERYTHING on this slide
Homework Make some Waves worksheet Due Monday (use your vocabulary words to help you answer the questions All questions must be answered in complete sentences
Vocabulary Waves- a way that different types of energy can travel. Medium- a substance or material that carries the wave Matter- anything that has mass and takes up space Write EVERYTHING on this slide in your foldable boxes
Vocabulary Energy- the ability to do work. Mechanical wave- requires a medium through which to travel. Write EVERYTHING on this slide in your foldable boxes
Vocabulary Transverse wave- a wave in which the particles of the medium move perpendicular (or right angled) to the direction of energy flow (example = light waves and surface ocean waves) Longitudinal wave- a wave in which the particles of the medium move parallel (back and forth) along the direction of energy flow (example = sound wave) Write EVERYTHING on this slide in your foldable boxes
Vocabulary Trough- the bottom or lowest part of a wave, which happens every wavelength. Crest- the top or peak of a wave., which occurs every wavelength. Wavelength- the space between two identical parts of a wave (from a crest to a crest, or a trough to a trough; the length of ONLY 1 wave) Write EVERYTHING on this slide in your foldable boxes
Vocabulary Amplitude- the height of the wave. This can be measured vertically from crest to the rest position or rest position to trough. Frequency- the number of time a wave passes a point in one second Write EVERYTHING on this slide in your foldable boxes
Warm Up Write this in your notebook on a blank page Predict how you could make a slinky move similar to a wave you may have seen in the ocean Remember, its a prediction..
