Lesson Plan – The growth and survival of living things are affected by physical conditions of their environment

Learning Intention:  Students become aware of the effect of the life history trade offs an animal must make for survival.

In this lesson students will learn:

  • Life has existed on Earth for approximately 3.5 billion years and has changed and diversified over time (ACSBL088)
  • Natural selection occurs when selection pressures in the environment confer a selective advantage on a specific phenotype to enhance its survival and reproduction; this results in changes in allele frequency in the gene pool of a population (ACSBL090)
  • Populations with reduced genetic diversity face increased risk of extinction (ACSBL095)
  • Explore and draw conclusions from the data they collected (Under the Science Inquiry Skills provided by ACARA)

Timing:

This lesson is designed to be accomplished in a 60 minute time period, but you may find that your students benefit from additional time. This lesson can also be extended where students are able to write up a scientific report or be turned into a depth study (NSW) using the information they have collected and answered during the process of doing the worksheet.

Assumed Knowledge:

  • There are many different factors that affect an animal’s life such as predation, sickness etc
  • Animals have a finite lifespan
  • All living things follow a life cycle and in order to progress through, animals will have to eat, breathe etc
  • All living things will develop behaviours that are unique to them which helps them survive in the wild- with every behaviour there is an associated risk
  • Students are aware that living organisms learn and adapt from their surroundings thus making changes to their behaviour

Preparation:

To facilitate a streamlined lesson, it would be useful to let the students know that their upcoming lesson involves the use of technology. Students can play Arludo games on any device with internet connectivity including laptops, tablets and smartphones. Inglorious Baskers is also embedded directly into the worksheet, so there is no need for students to download any apps for this lesson.

Australian Curriculum Points (ACARA)

 

Science Inquiry Skills

  • Identify, research and construct questions for investigation; propose hypotheses; and predict possible outcomes (ACSBL061)
  • Represent data in meaningful and useful ways, including the use of mean, median, range and probability; organise and analyse data to identify trends, patterns and relationships; discuss the ways in which measurement error, instrumental accuracy, the nature of the procedure and the sample size may influence uncertainty and limitations in data; and select, synthesise and use evidence to make and justify conclusions (ACSBL064)
  • Select, construct and use appropriate representations, including models of DNA replication, transcription and translation, Punnett squares and probability models of expression of a specific gene in a population, to communicate conceptual understanding, solve problems and make predictions (ACSBL066)
  • Communicate to specific audiences and for specific purposes using appropriate language, nomenclature, genres and modes, including scientific reports (ACSBL067)

 

Science as a Human Endeavour

  • ICT and other technologies have dramatically increased the size, accuracy and geographic and temporal scope of data sets with which scientists work (ACSBL068)
  • Models and theories are contested and refined or replaced when new evidence challenges them, or when a new model or theory has greater explanatory power (ACSBL069)

 

Science Understanding

  • Life has existed on Earth for approximately 3.5 billion years and has changed and diversified over time (ACSBL088)
  • Natural selection occurs when selection pressures in the environment confer a selective advantage on a specific phenotype to enhance its survival and reproduction; this results in changes in allele frequency in the gene pool of a population (ACSBL090)
  • Mutation is the ultimate source of genetic variation as it introduces new alleles into a population (ACSBL092)
  • Populations with reduced genetic diversity face increased risk of extinction (ACSBL095)
