i. Showing the pieces

of polystyreneii. Students are given

the pieces of polystyrene andobserve it usingmicroscope

iii. Through discussionand questioning,students are ableidentify how the cellslook alike

Questions:a) What you can see or

observe throughmagnifying glass?

b) Can anybody try to drawroughly a diagram onthe whiteboard aboutwhat you can see?

i. In a groups, studentsdiscuss the structureof plants cell and

animal cells insidethe textbook

ii. Gather informationon living organismsand identify thesmallest living unit

that makes up theOrganisms.

iii. Making comparisonbetween animals cells

and plant cellBased on shape andsize

Questions:a) What you can compare

between animal cell and

shape and size of bothcells

RestructuringOf ideas(40 minutes)

Observations:

i. Students arepreparing slides of cheek cells and onion

cellsii. Students discuss in a

groups for carryingout an experiment

iii. In group of 6students carrying outan experiment

Preparing a slides of cheek cellsMethod:

i. Using the blunt end

of clean toothpick,carefully scrapesome cells from theinside of your cheek

ii. Spread the scrapingsonto clean slide

iii. Add a drop of iodinesolution to the smear

iv. Place a cover slip atan angle to thesolution on the slide.Slowly slide the cover

slip to cover thespecimen withouttrapping any airbubble

v. Clear and dry up anysolution on the slideand around the coverslip with a filter paper

vi. Examine the cheekcells under themicroscope, first onlow magnification,

then on highmagnification. Drawthe structure of thecheek cells in thespace provided

Preparing slides of onioncells

Application of ideas(10 minutes)

We can see thestructure of cheekcells and onion cellsthrough microscopeby using low objective

lenses The diagram was drawn toshow how the cheek cells andonion cells look a like.

The part of animal cells andplant cells are labeled, so thatwe can compare the

differences between both cells

Students are given the chart of similarity and the differencesbetween plant cells and animalcells.

They need to complete thechart given

Reflection

(10 minutes)

The structure of plant

cells and animal cells

1. Students make a

3-2-1 summary 3 things I
