Space to grow

Science Year 3
This unit is part of Year 3 Science Roots and Shoots

Objectives

You agree to help Zinnia, a friendly alien who wants to farm human food in space. She needs you to find out what plants need to grow strong and healthy. Are you up to the challenge? You will need to do some scientific investigation and research over the coming sessions.

Science Objectives
i) Explore the requirements of plants for life and growth (air, light, water, nutrients from soil, and room to grow) and how they vary from plant to plant.

Working Scientifically

  1. Ask relevant questions and using different types of scientific enquiries to answer them.
  2. Set up simple practical enquiries and comparative and fair tests.

You Will Need

Provided Resources

  • 6 word cards (20 x 6 cm approx.)
  • A copy of the 2 task sheets each & some display shapes if you want to create a display

Additional Resources

  • Age appropriate non-fiction books on plant function, growth and structure, etc.
  • Access to computers for research
  • Chunky permanent markers
  • A few trays of seedlings
  • Compost & 18 medium flowerpots
  • A calendar & sticky labels
  • Green photocopy paper & different shades of green tissue paper

Lesson Planning

Teaching

  • Set up an enquiry to test our theories on what plants need to grow and thrive.
  • Research plant facts using books and the Internet.

Activities

  1. Become Planet Earth plant research experts for an alien called Zinnia.
  2. Discuss and decide all the requirements we think plants need to grow strong and healthy.
  3. Set up a plant growth investigation to test our theories.
  4. Begin to take measurements of height and make notes on observations.
  5. Research some interesting plant facts from books and the Internet.
  6. Create a display of “Did you know …?” facts.

Investigation - observing over time
Make a list of what we know and what we want to find out. Plant some beans in transparent jars and place them in different conditions to begin some observations. Use data loggers and other equipment to record light levels, water etc.
