Lesson Title:  Building a life

NC Ref: 

Objectives:    

Lesson outline:

Starter – Discuss what the human body is made up of.  Discuss that we (and all other organisms) are made up small ‘building blocks’ called cells (as a house is made up of bricks).

Main – Pages 8 and 9 – Exploring science 7
            Discuss briefly the history of cells and Robert Hooke (opportunity for Thinking Skills exercise where you read them the Robert Hooke story).

        Look at the diagrams of animal and plant cells.  Compare the drawings and photos. Discuss the features of each cell in turn – possibly using the nightclub model.

Nucleus – The manager who ‘controls’ everything (not a brain!)
Cell surface membrane – bouncer
Cytoplasm – dance floor
(can also apply to chloroplasts – snack bars; vacuole – bar; cell wall – club wall)

Worksheets Cut and stick (warning - quite time consuming) 7Ab/4 and 7Ab/3 – label and add functions.  Or children to copy and label plant and animal cells.  Stress the 3 features that plant cells have that animal cells do not.  Discuss the function of each of the cell parts. 

Could show children model plant and animal cells, or the children can make their own model cells, see model cell sheet.

Show brainpop demo on cells

Plenary – recap label and functions.
            Worksheet 7Ab/7 could be used.  Or play cells splat
Extension  Worksheet 7Ac/4

Homework Suggestion: 

Resources: There are sort cards - see technicians.  Glue, scissors, coloured pencils, mode cell equipment if necessary (wallpaper paste, balloons, strong plastic bags, sellotape, scissors, platic tubs).  Video - Secondary Science from Channel 4 Schools - Scientific Eye - Life and Living Processes 2 - Cells (in Sc8 cupboard).  SEN sheets.  Boardworks ppt.  Summary sheet, word list target sheet     link to technicians list

Lesson Title: Seeing is believing

NC Ref: 

Objectives:    

MK – Microscopes are needed see cells, how to use a microscope  
SK – How to work out a microscope magnification; how to prepare a slide for viewing ; stains can be used to show up various parts of a cell more clearly.
CK – Different stains are used for different purposes; micrometer is a unit of measurement

Lesson outline: (please note this content could be stretched over 2 lessons)

 Starter- Discuss problem of looking at small cells.  Pupils to decide how to overcome this problem.  Or draw animal and plant cell on board - no labels - students add labels. Or use cells starters sheet.

 Main – Introduce the microscope – emphasise care needed when handling. Go through how to use microscope (Page 6 Exploring Science 7).

 Label microscope (Worksheet 7Aa/4)

 Pupils to focus microscopes using various pre-prepared slides.  Could use Microscope photos, Microscope worksheet

 Make own slides – red onion good, then there’s no need for stain.  Or use white onion cell and stain with iodine. 

Can snap rhubarb in half, peel away the thin inner layers to show xylem.  Can use pre-prepared animal cell slides.

(page 7 – Exploring Science 7 will help)  

Draw calls and note magnification  (magnification = eyepiece lens X objective lens). 

Could do an investigation into which stain is best - see teachers guide.

Plenary – recap parts of microscope and how to make a slide.  Use 7Ab/9 to spot problems - could project and use as whole class exercise.

Extension Working out magnification (Page 7 – Exploring Science 7 or bottom of worksheet 7Ab/8)

Unit No 7A   
 

Lesson Title: Shaped for the job

NC Ref: 

Objectives:    

MK – Cells have different shapes to perform certain functions.     
SK – How ciliated epithelial cells, muscle, nerve, palisade and root hair cells are adapted to their functions.
CK – Historical ideas and development of cell theory

Lesson outline: 

Starter- Discuss the question – Are all cells in an animal or plant identical?

Or could ask how a town bus is different to a long distance coach, why they are different or compare the design of a racing car and a family car, etc to introduce the idea of specialisation..

Main – Use pages 10 and 11 – Exploring Science 7 to discuss differences in the cells shown.  Discuss why these differences exist.

May use pre-prepared slides (ciliated epithelial, muscle, xylem, palisade, nerve etc) to reinforce this is wanted.  Use rhubarb for xylem, freshly germinated cress / mustard for root hair, raw meat for muscle - use cavity slides if possible.

Pupils need to make copies of these cells (if wanted you can make or show 3D models although this is time consuming but enjoyable)

Or you could give each child / pair a specialised cell (see 3D models) to research (see sheet - Name of specialised cell, what job it does and what features it has to help it) and then present to rest of class, possibly a poster / 3D diagram - notes to be made by other members of group - see sheet.

Could dissect a hens egg to show all the different types of tissue.

Cells plenary could be questioning sheet

 

Worksheets 7Ac/1;  7Ac/2 and 7Ac/3 available.

Cell division – discuss how we make new cells (page 13)

Show brainpop on specialised cells

Plenary – Recap cells, adaptations and functions

 

Extension – work out how many cells would be produced over 4 weeks if it takes a bacterial cell just 1 hour to divide.

Homework Suggestion: Research what exactly a tumour is.

Lesson Title:  Lesson Title: All systems go

NC Ref: 

Objectives:    

MK – Cells of the same type can group together to form a tissue. Different organ systems work together to form organ systems.  Cells, tissues, organs and organ system all make organisms.
SK – Functions of nerve and muscle tissue. Know functions of digestive, breathing, circulatory and nervous systems.– Excretory system

Lesson outline: 

Starter – Discuss the fact that single cells join to form tissues.  Discuss what  many tissues together form.  Organisms starter.

Main-  See how many different organ pupils can name.  Draw outline of the human body and ask pupils to draw on different organs that they come up with.  (you may need to help them with organ names)

Discuss how many of these organs work together to form organ systems.  Pupils to come up with as many different organ systems as possible.  Make a list on the board.

Worksheet 7Aa/1 and 7Aa/2.  Use Exploring Science and other biology books to identify organs and organ systems. More able pupils could make brief notes on each organ system.

Plenary- Describe different organs or systems and pupils need to try and identify them (or pupils could do descriptions) Or Card chase

CK –

Lesson outline: 

Starter – How do plants reproduce?  Discuss pupils ideas on this  (lot of this is covered in KS2) and how flowers are involved (reproductive organs)

Main – Flower dissection in small group.  Pupils test themselves on how many ‘bits’ they can name. Complete worksheet 7Ae/1 in this group.

Each group share findings with rest of class.

Pupils to draw and label dissected flower using page 14 Exploring Science 7 to help.

Unit No 7A   
 

Lesson Title:  A seedy story – part 2

NC Ref: 

Objectives:    

MK –Sexual reproduction needs male and female sex cells to join, pollen tubes grow down style to the ovary, fertilisation leads to formation of embryo inside a seed 
SK – Fertilisation is the joining of nuclei; sexual reproduction leads to new varieties
CK – Which part of the flower becomes which part of the fruit; meaning on words zygote and gamete

Lesson outline: 

Starter – Discuss what is meant by sexual reproduction and pollination.  How can pollination occur?  Show brainpop - pollination.

Main – Discuss the need for pollen to be transferred.  Discuss how this can occur – insects versus wind.  What will pollen need to like to be transferred in each manner (Page 14 Exploring Science 7) ?

Discuss what happens once pollen has been transferred (growing of pollen tubes).  (Page 15 Exploring Science 7, worksheet 7Ae/6) 

Discuss the joining of the sex cells (nuclei for more able pupils) as being fertilisation.  Discuss making of an embryo which is found in seed and ovary becomes the fruit.

Show apple and identify the structures or half a bean seed.

Worksheet 7Ae/8 good summary for plant fertilisation.

Can look at the factors affecting pollen tube growth - see Teachers guide - Sc1 opportunity.

Plenary – go through movement of pollen to the formation of an embryo.

Extension – How sexual reproduction leads to new varieties.
