Daily Question: Will come later after you copy the agenda. March 16th, 2015 Thank you for not chewing gum  Today’s Agenda: Bell work Copy Agenda Pass back papers Review cell parts Intro to Microscopes Materials: Pencil, agenda, Science Notebook, worksheet Learning Target: Today we will review the parts of plant and animal cells by making a Venn diagram and begin learning how to use a microscope by learning the parts of a microscope. Daily Question: Will come later after you copy the agenda.

End of Quarter Reflection Get out your end of quarter reflection and read it over so you remember what you wrote. Share it with your shoulder partner…you read theirs and they will read yours. Make sure you heading is on your paper. You will turn them in when finished…put them in the drawer.

Compare plant/animal cells Plan for the day… Compare plant/animal cells Learn about the different parts of a microscope.

BASIC BUILDING BLOCKS OF LIFE and ALL LIVING THINGS ARE MADE OF CELLS

Prokaryotic: most simple cell Prokaryotic: most simple cell. Bacteria - single-celled, DNA floating around Eukaryotic: more complex, genetic material (DNA) in nucleus, PLANTS AND ANIMALS Organelle: small “organs”, parts of the cell, all have a specific function

Cell Theory Robert Hooke: 1st person to coin the term “CELL” Looked at cork under a microscope CELL means “little room”

Cell Theory All living things are composed of one or more cells. Cells are an organisms’ basic unit of structure and function. Cells come only from existing cells.

MICROSCOPE RULES THINGS TO REMEMBER….. Always carry the microscope by the arm and the base with two hands. ALWAYS start with the lowest magnification (low objective – red –X4). Lower the stage to its lowest point before placing a slide on the stage. Focus 1st using the coarse adjustment knob.

MICROSCOPE RULES Then use the fine adjustment knob. Increase magnification by moving to the 10X objective (yellow). NEVER, I repeat NEVER, use the coarse adjustment knob when using the highest power objective (x40 – blue).
