Draw The Core

  1. 1. Draw the CoreLabel if you’re ableAnnotate if you’re greatStephen Taylorhttp://sciencevideos.wordpress.com Draw the Core 1
  2. 2. Draw the Corehttp://sciencevideos.wordpress.com Draw the Core 2This presentation is for practice with assessment statements whereyou need to draw, label, annotate or where a diagram would be veryhelpful to describe, outline or identify.One slide has the assessment statement. The next has the diagramand the last has the diagram with labels.How could you use it in your revision?• QuickDraw flashcards – can you draw the item in the statement?• Labeling practice – can you add the correct labels?• Explain, outline, annotate, describe practice. Take the diagram orimage and use it to help in your treatment of objective 2 and 3assessment statements.This is a work in progress – but you mightfind it useful. It will be updated later.The diagrams in the presentation are all creative commons (unless otherwise noted), which means you canshare, edit and print them, as long as you cite the source as http://sciencevideos.wordpress.com.Remember:It’s an exercise inclarity, not acolouring-incompetition!Assessment statements have been taken from the online IB Biology subject guide:http://xmltwo.ibo.org/publications/migrated/production-app2.ibo.org/publication/7/part/2/chapter/2.html
  3. 3. Drawing in IB Biology Examshttp://sciencevideos.wordpress.com Draw the Core 37. (a) Draw a labeled diagram showing the ultrastructure of a typical prokaryote. [4]• You can use pencil and a ruler.• You must not use coloured pencils.As of 2011, exams will be scanned and look like this:This bit gets cut offThe scanning machine only looks inside the boxes, so stay inside!Use extra paper if needed, but include a note to that effect in this box.Make sure the extra paper is labeled clearly.• Draw clearly! Not too light or messy.• Practice first on the scrap paper.
