Dead or alive!

Science Year 2
This unit is part of Year 2 Science Habitats

Objectives

Look at a live spider, a dead spider and a toy spider. What are some of the differences between the live spider and the dead one? And the dead spider and the toy one? How can we work out what's alive and not alive? Is it sometimes difficult to tell? Armed with all these questions, go outside and collect something alive, something dead and something that was never alive. Sort these specimens into three categories.

Science Objectives
i) Explore/compare the differences between things that are living, dead, and things that have never been alive.

ii) Identify that most living things live in habitats to which they are suited and describe how different habitats provide for the basic needs of different kinds of animals and plants, and how they depend on each other.

Working Scientifically

  1. Ask simple questions and recognise that they can be answered in different ways.
  2. Observe closely, using simple equipment.
  3. Identify and classify.
  4. Use their observations and ideas to suggest answers to questions.

Lesson Planning

Teaching

  • Explore outside, and through observation, the differences between things that are living, dead, and have never been alive.
  • Discuss the features of those things that are living, dead and have never been alive.
  • Find, classify and label specimens into categories.
  • Engage in further discussion and thought around these questions: A robot can move, so why is it not alive? If a robot magically came to life, how could we test to make sure this were true?

Activities

  1. Understand the differences between things that are living, dead, and things that have never been alive.
  2. Understand the key features of things that are living, as opposed to dead.
  3. Be able to categorise specimens according to their features.

Investigation - exploring, sorting, classifying and identifying, problem solving
