      Offspring: similar but not identical

      I can describe how offspring of different animals are similar but not identical to their parents.

      Lesson details

      Key learning points

      1. Living things produce offspring of the same kind.
      2. Offspring share some characteristics of their parents.
      3. Normally offspring vary and are not identical to their parents.

      Keywords

      • Offspring - Living things create offspring when they reproduce.

      • Similar - Things that are similar have some things in common or are alike in some ways.

      • Vary - To vary is to differ or change.

      • Identical - Things that are identical are exactly the same as each other.

      • Variation - A variation is a difference between two or more things.

      Common misconception

      Pupils may think that male animals get their characteristics from their father, and female animals from their mother, with no characteristics shared between offspring and parents of different sexes.

      Use the images and examples in the lesson to make it clear that offspring share a combination of characteristics of both of their parents, regardless of sex.

      For Task A, pupils can identify similarities between themselves and a parent. If possible, encourage them to bring in photographs of their parents and provide them with mirrors to make their observations.
