Primary 5 ScienceHome-based Lesson

• FROM PARENTS TO YOUNG

2
What you will learn

• Reproduction in living things
• Hereditary characteristics in animals
• Hereditary characteristics in plants
• Characteristics that are not hereditary

3
Reproduction in Living Things

• All living things reproduce.
• Mammals give birth to their young
• Insects lay eggs which hatch into the young.
• Fishes lay eggs/give birth.
• Birds lay eggs which hatch into the young.
• Plants reproduce through the process of
  pollination.

4
Reproduction in Living Things

• All living things reproduce. (Video)
• Chicken egg hatching
• Moth egg hatching
• Whale giving birth

5
Reproduction in Living Things

• Living things reproduce to ensure the continuity
  of their own kind. Thus parents pass on their
  characteristics to their young during
  reproduction. This process is called heredity.

6
Hereditary characteristics - Animals

• Animals pass on hereditary characteristics to
  their young in order to ensure continuity of
  their own kind.
• Examples of characteristics that are passed on -

• Height
• Colour of eyes
• Colour of skin
• Blood type
• Type of ear lobe

• Type of hair
• Colour of hair
• Facial features
• Others

7
Hereditary characteristics - Animals

• LETS EXPLORE!
• Compare yourself to your parents. Identify some
  of the characteristics that each of your parents
  passed on to you.
• Share your findings with your parents.
• (Use Worksheet Activity 1 Part 1)

8
Hereditary characteristics - Plants

• Like animals, plants pass on hereditary
  characteristics to their young in order to ensure
  continuity of their own kind.
• A plant will always have fruits and flowers that
  are similar to its parent plants.
• Examples of characteristics that are passed on -

• Colour of fruit
• Colour of flowers
• Taste of fruit
• Presence of seeds

• Shape of fruits
• Size of fruits
• Others

9
Hereditary characteristics - Plants

• LETS EXPLORE!
• Get a red apple and a green apple from the
  supermarket. Try the red apple on one day and the
  green apple on another day. Pen down the physical
  differences in part 2 of Activity 1.
• Share your findings with your parents.
• (Use Worksheet Activity 1 Part 2)

10
Characteristics not passed down from parents to
young

• Some physical features are not hereditary.
  Examples of such physical features are
• hair length.
• length of fingernails.
• type of language spoken.
• others.
