Year 5 - Science

Insects (non-statutory)

Reproduction and life cycles: animals

Unit Summary

This unit explores the life cycles of mammals, amphibians, insects, and birds, and the reproduction process in plants and animals. It focuses on recording data, presenting findings with conclusions, and evaluating scientific evidence to support or refute ideas in various presentation formats.

Lesson Summary

You will learn to identify and name insects and describe their common features.

Key Notes

  • An insect is a small animal that has six jointed legs, and typically one or two pairs of wings
  • Insects have three parts to their segmented bodies (head, thorax, and abdomen) and a pair of antennae
  • Insects are invertebrates (have no backbone) and have an external shell (exoskeleton)
  • Common insects are ants, flies, butterflies, and beetles

Vocabulary To Learn

  • insect: An insect is an invertebrate animal that lays eggs and has antennae, six legs and a body divided into three segments.
  • antennae: Antennae are a pair of long, sensory organs on the heads of insects.
  • segmented: Something that is segmented is in segments or sections.
  • invertebrate: An invertebrate is an animal that does not have a spine or backbone.
  • exoskeleton: An exoskeleton is the hard outer layer that covers, supports, and protects the body of an invertebrate.

Common Mistakes To Avoid

  • Pupils may think that all small creatures, or 'minibeasts', are insects.

3 Quick Questions (With Answers)

1. Explain the scientific idea in this lesson using two key points.

An insect is a small animal that has six jointed legs, and typically one or two pairs of wings. Insects have three parts to their segmented bodies (head, thorax, and abdomen) and a pair of antennae.

2. Define this scientific word and use it in context. 'insect'

An insect is an invertebrate animal that lays eggs and has antennae, six legs and a body divided into three segments. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: Pupils may think that all small creatures, or 'minibeasts', are insects. Correction: Explain that an animal is only an insect if it has the characteristics of insects. Use lots of examples and non-examples to make this clear.
