This activity is linked to the National Profiles, Level 4, Science and Mathematics.

Materials:

A large collection of different seeds and seed pods

Stimulus work:

  • Discuss the way different plants spread their seeds (do not rely on natives at this stage)
  • Explore the reasons why plants need to spread their seeds. Why can’t they just drop them right underneath the parent plant?
  • Encourage students to handle a variety of seed pods and discuss the different ways plants spread their seeds.

National Profiles, Level 4, Science
Life and Living

A student
  • Identifies events that affect the balance of life in an ecosystem
  • Explains the major systems of living things and the way that they function

Natural and Processed Materials

A student
  • Recognises and describes conditions that influence reactions and changes in materials

Working Scientifically

A student
  • Identifies the factors and controls that need to be considered in investigations and ways of achieving control
  • Collects and records information as accurately as the equipment permits and according to the purpose of the investigation
  • Draws conclusions based on the information gathered and the reasons for carrying out the investigation
  • Reviews findings to see if the conclusions are reasonable answers to the questions asked
This project also applies to the Mathematics curriculum.

National Profiles, Level 4, Mathematics
Chance and Data

A student
  • Uses numerical and other information to place things in order of least likely to most likely to happen
  • Collaborates in deciding what data is to be collected and assists in its collection
  • Experiments with organising and showing data in forms that help to answer questions
  • Summarises data using simple fractions, highest and lowest and middle scores and means
  • Reads and describes information from tables, diagrams, line and bar graphs

Number

A student
  • Counts, places in order, estimates and describes with common and decimal fractions
  • Identifies, continues and invents number patterns involving multiplication and division
  • Uses an understanding of numbers and number relationships to make and complete equations
  • Makes suitable choices about when and which of the four number operations to use
  • Uses a variety of ways to mentally calculate involving both exact and approximate answers
  • Adds and subtracts numbers having the same number of decimal places, multiplies and divides whole numbers and decimals by single digit numbers when working with numbers, money and measurement
  • Uses a calculator to carry out tasks using decimals and when more than one operation is needed

Measurement

A student
  • Selects appropriate attribute and units to describe and compare objects
  • Measures and makes things using conventional units and measuring equipment paying attention to measuring length, mass, capacity and angle
  • Reads scales to the nearest measurement mark
  • Uses the known size of familiar things to estimate
  • Estimates and measures time and the duration of time and prepares possible timetables
  • Understands and uses relationships between measurements of some common shapes
