How are living things classified?

Science Year 4
This unit is part of Year 4 Science Name That Living Thing!

Objectives

Look carefully at features of the living things you found in the local area. Make a branching database to sort and identify the local invertebrates. This can be linked to a mathematics block on statistics and data handling.

Science Objectives
i) Recognise that living things can be grouped in a variety of ways.

ii) Explore and use classification keys to help group, identify and name a variety of living things in their local and wider environment.

Working Scientifically

  1. Ask relevant questions and use different types of scientific enquiries to answer.
  2. Gather, record, classify and present data to help answer questions.
  3. Record findings using simple scientific language, drawings, labelled diagrams and keys.

Other Curriculum Areas
Computing (This session can cover some computing objectives if appropriate software is available )

  • Select, use and combine a variety of software (including internet services) that can accomplish given goals, including collecting, analysing, evaluating and presenting data.

Extended Writing Opportunities
Biography: Research some key facts about Carl Linnaeus and write a short biography about him explaining his importance.

Lesson Planning

Teaching

  • Observe features of living things and sort them into different groups.

Activities

  1. Understand why it is useful to classify living things.
  2. Answer questions about the features of insects, arachnids and plants found in the local area.
  3. Create a branching database/dichotomous key to sort and identify local invertebrates.
  4. Understand why it is important to make accurate observations when describing features of living things.

Investigation - sorting, classifying and identifying
