Egglayers united

Meet our flock, feed them, check for eggs, pick one up if you are brave and quick enough

Overview

Chick, chick, chick, chick, chicken. Lay a little egg for me!

Meet our flock, feed them, check for eggs, pick one up if you are brave and quick enough.            

As rare as hens’ teeth, chalky shells, warm eggs, 'egg'citing 'egg'speriments, eggstremely strong - dissolving shells in vinegar, loading an egg with phenomenal loads.

Poems, battery farms vs free range farms. A good close look at and feel of a real live bird; scaly feet, hidden ears, gizzards of stones.

Programme of study

Science Key Stage 2

Working scientifically

  • asking relevant questions and using different types of scientific enquiries to answer them
  • setting up simple practical enquiries, comparative and fair tests

Animals including humans

  • recognize that living things can be grouped in a variety of ways
  • describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences, including microorganisms, plants and animals
  • Identify how animals are adapted to suit their environment in different ways and that adaptation may lead to evolution
  • describe the differences in the life cycles of a mammal and a bird and the life process of reproduction in animals
  • identify that animals, including humans, need the right types and amount of nutrition, and that they cannot make their own food; they get nutrition from what they eat
  • identify that humans and some other animals have skeletons and muscles for support, protection and movement
  • describe the simple functions of the basic parts of the digestive system in humans and chickens
  • recognize the impact of diet, exercise, drugs and lifestyle on the way their bodies function

Properties and changes of materials

Explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible, including changes associated with burning and the action of acid on bicarbonate of soda.

Learning objective
  • Describe the similarities and differences between chickens and humans, discussing that they can be grouped in a variety of ways e.g. birds and mammals
  • Outline how animals have adapted to suit their environments
  • Describe the life cycle of a mammal and a bird
  • Compare dietary requirements and difference in digestion for humans and chickens
  • Measure the load bearing capacity of an egg
  • Predict the effect acid will have on an egg
  • Note the irreversible change of a shell dissolving in acid and relate it to dental care
Activity
  • Overview diary page and set 'eggpectations'
  • Consider the similarities and differences between mammals and birds using a Venn diagram highlighting the main features of classification
  • Discuss life cycle of birds and mammals. Write this around the oval shells
  • Visit the flock of chickens to discuss life processes common to animals and man
  • Feed chickens, examine types of food, collect eggs and discuss domestication
  • Introduce land use and welfare issues; battery vs free range
  • Examine egg boxes.

Break

  • Compare an egg with a standard 50g mass. Each individual estimates the weight then the real egg is weighed accurately in grams
  • How will we test the strength of the egg? What equipment will we use? How will we make it a fair test? What do you expect will happen?
  • Load the egg with weights until it cracks
  • Introduce acid rain issue; Carbon dioxide + rain water = acid rain. Chalky buildings can be eaten away, ponds affected, trees killed etc. Teeth and fizzy drinks
  • What affect will vinegar have on our egg? How will we test this? What will we use? Do we use a control?
  • Record all findings on the egg layers page in the Earth book
