Success Criteria

C1: Tissues &Organs

 Toknow that plants & animals contain organs.

 Toknow that tissues make up organs.

 Toidentify and locate the major organs of the humanbody.

 Toknow the function of our major organs.

Revise children's knowledge of seven life processes normally taught as MRS GREN.

Discuss make -up of human body as being organs. Usefull-sized model, ask children to identify the organs they knowand, where possible, their functions. Remove and replace allorgans.

Cut'n'stick labelling activity, ensuring that relevantorgans are behind others as appropriate, e.g. kidneys atback.

Key Objectives

C5

All pupils will recall that several life processes can beused to define living things, and be able to name many or all ofthese. They will recognise that the body is made up of organs, andbe able to name key organs (heart, lungs, digestive system) andwill know the function of these.

Most will recall all 7 life processes, and be able to nameall major organs, recalling the function of most. They willrecognise that organs are made up of tissues

Some will know functions of all major organs, and be ableto describe structure of tissues to make up organs.

Evaluation:

C2: The microscope

  To use a microscope safely and effectively

  To prepare simple specimens on a slide forobservation

  To make observations using a microscopes

Demonstrate the correct use of the microscope, appropriatevocabulary used. Function of each part explained. Demonstrate howto clean eye lens with lens tissue.

Children taught how to setup microscopes to examine prepared slides.

Children should be taughthow to make scientific drawings, e.g. solid line, unshaded inpencil, not sketched.

Key Objectives

S4

All pupils will be able to use a microscope, obtaining afocussed imaged use at least one magnification setting. They willrecord their observations.

Most will obtain several focussed images, drawingappropriate scientific observational drawings.

Evaluation:

C3: Observation of cells

  To know that plants are made up ofcells

  To learn how plant cells arestructured

  To make observationaldrawings

Review tissues/organs, and introduce structure of cells.Show main strucuture of plant celland label.

Demonstrate preparation of a slide, using onion epidermis.Talk through process, and revise notes for observationaldrawing.

Children to create onion skin slide, and recordobservations following LAT sheet (7a)

Outcomes to be assessed against LAT assessmentsheets.

Evaluation:

C4: Plant & Animal cells

  To know that plant and animalcells are similar, but have significant differences

  To be able to name the key partsof both plant and animal cells

  To know the main functions of eachpart of plant and animal cells

Review knowledge from last lesson on cell structure inplants.

Children use prepared cheek cell slides to examine animalcells. Make observational drawings.

Draw group together to review findings. Look in detail atdifferent structure of animal cells, identifying reasons.

Children to draw and label diagrams of both types of cell,noting differences. See Hodder p3

Key Objectives

S4, C1

All pupils will have drawn a diagram based on theirobservations of a human cheek cell. They will recognise that thecell has a wall and nucleus, and that it is different from a plantcell.

Most will identify the differences between plant and animalcells and give some reasons for differences.

Evaluation:

C5: Specialised cells

  To know that different cells canbe adapted for different function

  To recognise that organs are madeup of different types of cell

Link knowledge of cells to that of Organs

Display image of sperm cell on IWB noting that it is asingle cell. Discuss how it is well-suited to its purposes, usingrelevant terminology (adaptation, specialised, etc.)

Present children with examples of other specialised cells.Children should describe adaptations for purpose. (Matchingactivity where appropriate)

Key Objectives

C1, C4, C5

All pupils will recognise that different cells servedifferent functions, and will be able to give one or two examplesof this.

Most will be able to give examples of 2 or 3 specialisedcells, indicating how they are adapted for theirspecialisation.

Some will be able to explain how the adaptation of 5 ormore cells are suitable for their respective functions.

Evaluation:

C6: Cell reproduction

  To know how cells reproduce bydivision

  To revise knowledge of unit

Consider the development of tissues, including skin. Notethat dead cells fall away constantly. Children to consider wherenew cells come from.

Explain process of cell division, noting that nucleussplits meaning that each cell reproduced is a clone ofparent.

HW: Make a model of a cell (see C6)

The main section of this lesson should allow time to beleft to consider the homework task in detail, referring tolevelling according to LAT guidance.
