Presentation Transcript


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?


Seed dispersal

Seeds are dispersed in many different ways:

  • Wind

  • Explosion

  • Water

  • Animals

  • Birds

  • Scatter


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

  • 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)
