DK:
· systems do specific jobs and contain organs and other parts to carry out its job.
· All parts of these systems are made of tissues
· All tissues are made from billlions of microscopic cells
· That the same is true for all living things (plants also) / PK:
Investigate the types of cells in the human body
Success Criteria:
Be able to recall DK. To list some types of cells .
2 / LEARNING GOAL:
To be aware of the general structure of all cells and list some parts of cells / Model of animal cell
Text page 101
DK:
Cells contain structures generally named “Oganelles”
that perform specific functions for the health of the cell and for it to grow and divide.
List of Organelles and their functions. / PK:
Compare the organelles in plant and animal cells
Success Criteria:
Be able to recall some of the major organelles in a cell and compare plant and animal cells
3 / LEARNING GOAL:
To know the parts of a microscope. How to prepare a “wet mount slide” and view. / Use the Skills Activities pages 97 and 95 of the text.
DK
List of microscope parts.
Instructions on how to use a microscope / PK
Construct a “wet mount slide”
Apply DK to view the slide
Success Criteria:
To be able to view the newsprint on the wetmount slide and view prepared slides with highpower objective lenses
4 / LEARNING GOAL:
To know the meaning “magnification power” and how to calculate it / Book equipment for activity p97 of text.
DK
Magnification power is how many times bigger the image is made to appear than it really is.
Multiply the eyepiece lens power by the objective lens power / PK
Reading the power of lenses from a microscope and calculating Magnification powers.
Record by drawing specimens as viewed by a microscope
Success Criteria
Able to complete the worksheet on microscopes.
Able to draw specimens seen with a microscope
5 / LEARNING GOAL:
To know the organelles in a cell and their functions / Text page 101
Worksheet:
Characteristics of Plant and Animal Cells
Video:
Clickview “ Scope: Cell science”
DK
List and describe function of :
Nucleus
Cell Membrane
Mitochondria
Golgi bodies
Endoplasmic reticulum
Vacuoles
Cytoplasm
Chloroplast
Cell wall / PK
To differentiate between
A plant and animal cell
Success Criteria
To be able to list 5 organelles
6 / LEARNING GOAL:
To know how cell specialisation allows organisms to be more complex . / Video
Clickview “The Cell – How it works
DK
Cell Specialisation allows complex life forms. Simple life forms are unicellular and have no or little cell specialisation. Different cells built different types of tissues used to construct organs ect. / PK
To classify oranisms as simple or complex on the basis of cell specialisation.
Success Criteria
7 / LEARNING GOAL:
To understand the term “Field of view” and to use a cavity slide to view simple life forms from a pond .
DK
Field of view is the width of the circle visible in the microscope. / PK
Prepare a specimen of pond water and view to find simple organisms
Success Criteria
Can give the field of view of the microscope.
Can examine microscopic life forms
8 / LEARNING GOAL:
Techniques to make cell parts more visible / Book investigation “Examining Cells” Page 102 Part A and B
DK
Certain stains can be used to make cell parts more visible.
Peeling single layers of tissue help make cells easier to view / PK
How to prepare a slide using a stain.
Slivering speciments of leaves to view single tissue layers of cells.
Success Criteria
Identify nucleus ,chloroplasts,cell walls in cells and the stomata structure in epithelial leaf tissue (underside)
9 / LEARNING GOAL:
To understand the process of cell division
DK
Cells division is the basis of reproduction and growth
Success Criteria
To generally describe the process mentioning the chromosomes, the nucleus and the membrane division
8 / Assessment
Constructing a jelly model of the cell / Book activity with lab techs to have preset jelly plates and lollies available .
Models to be assessessed at end of lesson . They can then be taken by students to eat.
(note it probably won’t be the first cell that they have eaten today) (Mention also that there will also be plenty of their skin cells in the model as well. Have them wash their hands first.
DK
Organelles in a cell / PK
Modelling the cell
Success Criteria
A completed model with 7 organelles represented and labelled
9 to 15 / LEARNING GOAL: Research Assignment on a specialised cell
