Will White Copernicus School
60l0 Throop Street
1. Being able to identify parts of plant and animal cells and to
describe function(s) of each part.
2. Being able to distinguish between plant and animal cells.
Solution of sodium borate (see attached)
Solution of polyvinyl alcohol (see attached)
Zip-lock transparent sandwich bag for each pupil
Lima bean seeds - dyed
Dry rice - dyed
Packing material bubbles
Containers - McDonald`s hamburger boxes and petri dishes
1. Abstract to Concrete
a. Develop vocabulary and describe functions associated with
each organelle by:
(1) Listing the following on chalkboard and discussing functions:
plasma membrane cytoplasm nucleus cell wall
vacuole mitochondria ribosomes chloroplasts
(2) Use overhead projector and transparencies to show
plant and animal cells to reinforce structure name and
function of each part.
b. Construct models of plant cell and animal cell by adding
mixture of polyvinyl and sodium borate into sandwich bags. To
this mixture add organelles (nucleus-clay nuclear membrane-
saran wrap vacuoles-bubbles mitochondria-dyed dry rice
ribosomes-peppercorns embedded in thin rolls of clay) (cell
wall and chloroplasts-hamburger container and dyed lima beans
added to plant cell.
c. Review with worksheet that requires students to distinguish
between plant and animal cell and describe functions of each
2. Concrete to Abstract
a. Worksheet used as guide in constructing models of plant and
b. Names and functions of each organelle discussed as each item is
c. Review structures and corresponding functions through use of
chalkboard and overhead projector.
1 liter-polyvinyl alcohol mixture
l. Using magnetic automatic stirring hot plate and large
beaker, heat l liter of distilled water to boiling.
2. 40 grams of polyvinyl alcohol powder added gradually
(approximately 2 or 3 grams at a time) until
dissolved. Continue adding polyvinyl powder until 40
grams have been dissolved in l liter of distilled
100 milliliters-sodium borate - Mix 4 grams of sodium borate
powder to 100 ml of tap water in container.
