Let's teach! Primary

Lesson 1

Is it living, non-living or once living?

Lesson Plan

Preparation

  • Collect some of the items mentioned in the last two paragraphs of the student summary e.g. bouquet of flowers, fruit, fossils, paper and wood, milk and cheese, flour. Collect the materials listed on the investigation sheet:
  • Collect the materials listed on the investigation sheet: 4 seedlings (such as bean plants) in small plastic pots or containers; a large shoe box lined with plastic; the shoe box lid with a hole, about 5cm diameter, cut to one side.

Curriculum links

  • Australian Curriculum: ACSSU044, ACSIS053, ACSIS054, ACSIS055, ACSIS057, ACSIS215, ACSIS058, ACSIS060
  • NSW Curriculum: ST2-4LW-S, ST2-1WS-S
  • VIC Curriculum: VCSSU057, VCSIS065, VCSIS066, VCSIS067, VCSIS069, VCSIS070, VCSIS072
  • WA Curriculum: ACSSU044, ACSIS053, ACSIS054, ACSIS055, ACSIS057, ACSIS215, ACSIS058, ACSIS060

Suggested teaching strategies

  • Collaborative learning
  • Scaffolding of learning

 

Introduction

  • Display the digital lesson to introduce the concept of what is living, non-living or once living.
  • The student summary and worksheet should be used together.

Development

  • Provide students with printable versions of the student summary and worksheet. Have students complete the worksheet.
  • Take the students on a ‘nature walk’ outside so they can observe their surroundings to identify living and non-living objects. Ask them to take note of any objects they’re unsure about.
  • Introduce the students to the experiment on the investigation sheet. The aim of the experiment is for students to understand that, like all living things, plants can and do move. Plants usually move slowly that we don’t notice. Plants respond to a number of different cues in their environment with movement. These movements are called ‘tropisms’ and include gravitropism (response to gravity), hydrotropism (response to water) and phototropism (response to light).

Differentiation

  • Show time lapse photography of a plant moving upward towards light. This could help some students to understand that plants do in fact move.

Conclusion

  • Discuss with the students after the activity how the experiment worked or didn’t work, what might have gone wrong, and what they would change to make it better.

Assessment

Worksheet answers

  1. (a)-(b) Answers might include items that move or have moving parts; e.g. clock, sun, clouds. (c) Answers could include because it doesn’t take in food or nutrients, have offspring, give off wastes etc.
  2. Teacher check
  3. Refer to 1(c)
  4. They were both once living
  5. Living: (d), (e), (g), (h)
    Non-living: (a), (b), (f), (i)
    Once living: (c), (j), (k)
  6. Possible answers: paper, wood, milk, cheese, flour

Investigation sheet answers

It is expected students will test to determine if plants grow towards the light (phototropism).
After about two weeks, with the box situated in a bright location and with regular watering, students should note the stems of the plants in the darkest part of the box are bent towards the light.

Science Year 3 Unit 1 Lesson 1 Slide 1

How do you know if something is living or non-living?

Science Year 3 Unit 1 Lesson 1 Slide 2

Look around your classroom
and decide what might
be living or non-living.

Science Year 3 Unit 1 Lesson 1 Slide 3

Desk and chair

You would be likely to say you and your teacher are living and your desk and chair are non-living.

Science Year 3 Unit 1 Lesson 1 Slide 4

But how do you know this?

Science Year 3 Unit 1 Lesson 1 Slide 5

Usually it’s easy to tell if something is living.

You would probably say you are living because you can move, grow and breathe.

Your desk can’t do these things so it is non-living.

Science Year 3 Unit 1 Lesson 1 Slide 6

Clouds

Fire

But sometimes non-living things can do some of the things that living things can do.

For example, clouds can move across the sky.

A fire can grow and
get larger.

Science Year 3 Unit 1 Lesson 1 Slide 7

However for something to be called living, it must have all the features of living things.

Living things, like humans,
other animals and plants,
can do the following…

Science Year 3 Unit 1 Lesson 1 Slide 8

Breathe (take in oxygen)

Take in food or nutrients

Respond to things around
them, like light or heat

Science Year 3 Unit 1 Lesson 1 Slide 9

Move (by themselves,
either whole body or
part of their body)

Reproduce (have ‘offspring’ like babies, or grow from seeds or spores)

Grow and change

Give off wastes

Science Year 3 Unit 1 Lesson 1 Slide 10

Fire moves, flows and seems to ‘eat’ things when it burns them. But fire does not reproduce.

It is non-living.

Science Year 3 Unit 1 Lesson 1 Slide 11

Clouds move and change colour and shape. They drop rain and can get bigger.
But they do not breathe,
eat or have offspring.

Clouds are non-living.

Science Year 3 Unit 1 Lesson 1 Slide 12

Water moves and changes state. While water might carry away wastes, it does not make waste or reproduce.

Water is non-living.

Science Year 3 Unit 1 Lesson 1 Slide 13

What about things like a bouquet of flowers and fruit you buy in a supermarket?

Science Year 3 Unit 1 Lesson 1 Slide 14

Cut flowers

The cut flowers are ‘once living’, once part of living plants.

Fruit is also once living.

Chopped fruit

Science Year 3 Unit 1 Lesson 1 Slide 15

Fossil

Decomposing grapes

Fossils are remains of once living animals.

Dead animals or plants are also once living.

Science Year 3 Unit 1 Lesson 1 Slide 16

There are many products made from living things.

Science Year 3 Unit 1 Lesson 1 Slide 17

Paper and wood were once part of living trees.

Science Year 3 Unit 1 Lesson 1 Slide 18

Milk and cheese come from animals such as dairy cows.

Science Year 3 Unit 1 Lesson 1 Slide 19

Flour is produced from wheat.

Science Year 3 Unit 1 Lesson 1 Slide 20

Can you think of other products made from living things?
