week 5 - Feb 25 - 29, 2008 & week 6- Mar 3 - 7, week 7 - Mar 10 - 14

We are currently studying organ systems in humans and comparing them to earthworm systems. I use a combination of reading and "reading diagrams and photos" from the text and Brainpop videos from the web (www.brainpop.com). These are animated short videos that explain various human systems. We have studied circulatory and nervous systems and touched on the respiratory system, briefly.

This week, we will study: cells - basics, including osmosis/diffusion; cell theory; observation of cells under the microscope; a homework assignment of building a cell model; and a lab on diffusion across dialysis tubing as a model for diffusion in the cell. This unit will run until March 11, with March 6 & 7 off for lessons taught by the school counselor.

week 2, quarter 3, Feb. 11 - 15. 2008

overview:

• complete living earthworm observation lab notes (in lab notebook)
  
• write a paper about the lab results based on the notes. (see attached copies)
• all 6th grade life science classes watch "Brainpop" (www.brainpop.com ) heart and circulatory system videos on Feb.14, "heart day"
• LIVING EARTHWORM OBSERVATIONS paper due Feb. 15, except P7, due Feb. 19.
• Also, on Feb. 15, Ms. P. will do a binder check. I expect to see a divider in the binder devoted to science. Science papers should be well organized behind the divider. We are 1/2 of the way through the year, headed for 7th grade. Make sure you're prepared! : > )
  

week 1, quarter 3, Feb 4 - 8, 2008
