This is HL #11. Using a sheet of loose leaf notebook paper with no edges, write using blue/black ink or pencil. Be sure to head your paper correctly (upper right hand corner with last name, first name; date; period; HL #11. Also, include the title, waves, on the first line. LETTER ANSWERS ONLY!
Students will be able to:
use information from textbooks and classroom discussions to
-compare and contrast characteristics of electromagnetic and mechanical waves by constructing a Venn diagram.
-explain the relationship between wavelength and frequency.
Students submitted their scientist card.
The do now was to read pages 187-189 in the text and complete a Venn diagram on the information.
Students then watched BrainPops on the electromagnetic spectrum and the water cycle.
Students received HL #11, which can be found at the top of this blog. There will also be a notebook check.
Students spent the remaining class time at the BBC UK site, learning about waves and their properties. Visit Dr. Gayden's Science Zone for October 11. Be sure to click the links under the date that has seventh graders at the top (this is the SECOND blog for this date!)
Information that should be in your notes:
Electromagnetic waves
-do not need a medium to travel
-can travel through a vacuum
-can be transverse waves with a crest and trough
-examples include visible light, ultra violet radiation, infra red waves, microwaves, radio waves, gamma waves, and X-ray waves.
Mechanical waves
-require a medium to travel, which may be either solid, liquid or gas
-can be transverse with a crest and trough
-can be compressional waves (also known as longitudinal waves)
-examples include sound waves, seismic (earthquake) waves, and water (ocean) waves
