  1. Barnacles can’t move, so finding mates can be difficult. How do you think these animals solve this problem? WARMUP!!!!! (activity # 3)

  2. GOALS • Analyze reproductive techniques in marine organisms and determine how such strategies evolved.

  3. Your Task: Mommy, Where do Babies Come from? Groups of 2:Each group gets an envelope PART 1: On your whiteboard: -Group the scenarios into similar problems 1. MATES ARE HARD TO FIND 2. MY EGGS WILL GET EATEN 3. IM TOO BIG TO REPRODUCE 4. MY EGGS ARE VULNERABLE -How do the animals solve the problem? YOU HAVE 15 MINUTES CHALLENGE QUESTION: GRAB A WHITEBOARD AND CLASSIFY THESE STRATEGIES AS SEXUAL OR ASEXUAL.

  4. USE YOUR NOODLE: • Barnacles and Sea Hares share a BIG problem when trying to find a mate. What is that problem?

  5. REPRODUCTIVE NOTES PAGE 12

  6. USE YOUR NOODLE: • The eggs of Salmon and Sea Scallops are vulnerable to attack. How do these animals get around this problem?

  7. REPRODUCTIVE NOTES PAGE 12

  8. USE YOUR NOODLE: • Coconut Crabs and Shrimp also have vulnerable eggs. How does their strategy differ from salmon and scallops?

  9. REPRODUCTIVE NOTES PAGE 12

  10. USE YOUR NOODLE: • Anemones and Corals have the problem of getting to big as they grow. How do they solve this problem?

  11. REPRODUCTIVE NOTES PAGE 12

  12. Your Task: Mommy, Where do Babies Come from? Groups of 2:Each group gets an envelope PART 2: On your whiteboard: - Match the animals to the REPRODUCTIVE STRATEGY they use. YOU HAVE 10 MINUTES

  13. USE YOUR NOODLE: • Which of the REPRODUCTIVE STRATEGIES you looked at today would be beneficial when mates are difficult to find? HERMAPHRODITISM: BROODING: CLONING: BROADCAST SPAWNING

  14. REPRODUCTIVE NOTES PAGE 12

  15. USE YOUR NOODLE: • Which TWOREPRODUCTIVE STRATEGIES you looked at today would be useful in protecting eggs from predators? HERMAPHRODITISM: BROODING: CLONING: BROADCAST SPAWNING • WhichSTRATEGY would OVERWHELM Predators?

  16. USE YOUR NOODLE: Can Broadcasters be Hermaphroditic? Why or Why not? WHATS THE BENEFIT OF THIS?

  17. USE YOUR NOODLE: Even though they both protect eggs from harm, BROADCASTING SPAWNING and BROODING do so in different ways What are those differences?

  18. USE YOUR NOODLE: What benefit would CLONING provide for an organism?

  19. USE YOUR NOODLE: • For the majority of animals we looked at today, when babies are born, they are released as microscopic plankton. What are the advantages to this? What are the disadvantages?

  20. USE YOUR NOODLE: • Which of the REPRODUCTIVE STRATEGIES you looked at today would be considered SEXUAL and which would be considered ASEXUAL? HERMAPHRODITISM: BROODING: CLONING: BROADCAST SPAWNING

  21. REFLECTION: • Below is a picture of a creature known as a abalone. What REPRODUCTIVE STRATEGY could it use? Explain your answer.
