Objectives:

Following are the syllabus objectives that need to be covered for Stage5- Science/ Unit: Structure and function

Structure and function

• 5Bs.01 Know that not all plants produce flowers.

• 5Bs.02 Identify the parts of a flower (limited to petals, sepals, anthers, filaments, stamens, stigma, style, carpel, and ovary).

• 5Bs.03 Describe the functions of the parts of a flower (limited to petals, anthers, stigma and ovary).

• 5Bs.04 Describe the human digestive system, including the functions of the organs involved (limited to mouth, oesophagus, stomach, small intestine, large intestine and anus), and know that many vertebrates have a similar digestive system.

Topic: 1

Topic Name: Plant Life Cycle

Notes:

  • Plants can be flowering or non-flowering.

  • Flowering plants produce flowers and seeds (e.g., sunflowers, mango trees).

  • Non-flowering plants reproduce without flowers. They may use:

  • Spores (e.g., ferns, mosses)

  • Cones (e.g., pine trees, conifers)

Even though they do not make flowers, they still carry out normal plant functions such as photosynthesis.

Topic: 2

Topic Name: Parts of a Flower

Notes:

Topic: 3

Topic Name: Functions of Flower Parts

Notes:

Parts

Functions

Petals

    • Brightly coloured to attract insects and animals for pollination

Anthers

    • Produce pollen grains, which contain the male sex cells

Stigma

    • Sticky surface that captures pollen during pollination.

Ovary

    • Contains ovules (female sex cells).

    • After fertilisation, the ovary develops into a fruit and the ovules become seeds.

Topic: 4

Topic Name: — Human Digestive System & Functions

Notes:

organ

function

mouth

    • Food is chewed (mechanical digestion).

    • Saliva begins chemical digestion of starch.

Oesophagus

    • A muscular tube that pushes food down to the stomach using peristalsis (wave-like movements).

Stomach

    • Stores food temporarily.

    • Releases digestive juices and acids to break down proteins.

    • Mixes food into a liquid paste called chyme

Small Intestine

    • Most digestion happens here.

    • Nutrients are absorbed into the bloodstream.

Large Intestine

    • Absorbs water and minerals.

    • Forms solid waste (faeces).

. Anus

    • Waste leaves the body.

Other Vertebrates

The following syllabus objectives are covered as part of studies for stage 5 Cambridge primary science:

Structure and function

• 5Bs.02 Identify the parts of a flower (limited to petals, sepals, anthers, filaments, stamens, stigma, style, carpel, and ovary).

• 5Bs.03 Describe the functions of the parts of a flower (limited to petals, anthers, stigma and ovary).

• 5Bs.04 Describe the human digestive system, including the functions of the organs involved (limited to mouth, oesophagus, stomach, small intestine, large intestine and anus), and know that many vertebrates have a similar digestive system.
