SIR

  • S – Describes asexual reproduction as reproduction where there is no fusion of gametes, and offspring are genetically identical to parents

    • Well presented information

  • I – Needs to define asexual reproduction

    • Need to put into own words


What is this why is it this shape what does it do

What is this? Why is it this shape?What does it do?


Seed dispersal
Seed dispersal

Seeds are dispersed in many different ways:

  • Wind

  • Explosion

  • Water

  • Animals

  • Birds

  • Scatter


Experiment
Experiment

  • You will design an investigation into seed wing length and time to fall. Decide on factors to be controlled. Collect results in rough at first

  • What is the independent variable? (thing you are changing)

  • What is the dependent variable? (thing you are measuring)

  • What are the control variables? (things that stay the same)


Hypothesis
Hypothesis

  • What do you predict will happen?

  • As seed length increases by _____, time to fall will ______ by _____


  • Checklist: Revealing patterns in data E (out of 8 marks)

  • Display your results in a simple table (1 mark)

  • Draw a bar chart/ graph using given axes and scales by your teacher (2 marks)

  • Record and draw a line graph for your results with the help of you teacher (3 marks)

  • Draw a line graph yourself that has some errors in scales and plotting of results (4 marks)

  • Correctly draw a line graph with correctly drawn scales and plotting of results (5 marks)

  • Draw a correct and appropriate line of best fit (6 marks)

  • Draw range bars or displaying data in scatter graphs to indicate spread of data (7 marks)

  • Correctly draw ranges bars and scatter graphs (8 marks)
