3.8 reproductive systems draw, label, annotate

  1. 1. Draw – Label – Annotate (Starter activity) Previously you have learnt about the digestive system. Get ready, make sure you have access to: • (sharp) pencil • ruler • A3 paper By Chris Paine https://bioknowledgy.wikispaces.com/
  2. 2. Draw – Label – Annotate Guidelines • You are drawing, labelling and annotating the reproductive systems: 3.8 describe the structure and explain the function of the male and female reproductive systems • The group will the highest total will receive a reward.
  3. 3. Draw – Label – Annotate Guidelines 1. 2. 3. 4. 5. 6. 7. 8. Form groups of three students Everyone draws a male and female reproductive system DO NOT Label (2 mins) Pass your drawing to the next person in your group Everyone labels the drawing they have in front of them DO NOT Annotate and DO NOT add to the drawing (1 min) Pass the labelled drawing to the next person in your group (you should be looking at a different drawing again) Annotate EXISTING LABELS only (3 mins) Now for the reflection: trade your group’s papers with a different group (the teacher might ask you to rotate papers between groups rather than trade) Mark the drawings according to the mark scheme you are shown on the next slides
  4. 4. 1 mark for each correct label (10 max) 1 mark for each correct annotation (9 max) a. uterus • Muscular womb for development of fetus b. fallopian tube (oviduct) • • Connects the ovary to the uterus Fertilisation happens here c. ovary • (meosis) eggs produced, stored and mature d. endometrium (lining of the uterus) • • develops each month in readiness for the implanation of a fertilised egg (site of implantation becomes the placenta) e. cervix f. vagina • • Muscular opening/entrance to the uterus Source: i-Biology • Accepts the penis during sexual intercourse / connects the uterus to the outside Sperm deposited here
  5. 5. 1 mark for each correct label (8 max) 1 mark for each correct annotation (10 max) c. urethra • Deliver semen to the outside/vagina d. Penis/erectile muscle • • Becomes erect to penetrate the vagina during sexual intercourse Delivers sperm to the top of the vagina e. Seminal vesicle • • adds nutrients including fructose sugar for respiration Adds mucus to protect sperm in the cell f. epididymis • Sperm mature here and become able to move a. Vas deferens (sperm duct) g. testis (pl. testes) • • Duct that carries sperm to the penis Produces (milions) of sperm (every day) b. Prostate gland h. scrotum • • adds fluids that neutralise the vaginal acids Source: i-Biology Protects and holds the testes outside the body (to maintain a lower optimum temperature for sperm production)
  6. 6. Deductions • -1 for for label lines not drawn with a ruler • -1 arrow heads on label lines (I know the example diagram did have arrow heads, but this is bad practise) • -1 for drawing <1/2 a page in size • -1 for shading • -1 for sketching rather than outlining n.b. deductions are per drawing, not per incidence
  7. 7. Reflection • Total the marks by group to see which group did best – Rewards for the best group • In groups discuss what group you are marking did well and what they could improve on. Comments should be in terms of “next time they should …” • As a class share your “next time” recommendations is there a lot of similar mistakes being made? • Return drawings • Using your feedback produce an excellent example drawing to add to your notes
