1
Living in the tide pools

• With supplemental tour of horticulture

2
Outline of the day

• Quiz
• Introduction to the lab
• Lab!
• Check out
• Get a stamp
• Make sure I mark you down for attendance

• Ends at ____

4
Lab this week!

• Preparing for our tidepool trip
• Where were going
• What were going to do while there
• Applying what we learned last week to real plants
• A tour of horticulture!
• Todays worksheet is based on this part

5
The intertidal zone

• Area where land meets sea
• Can be rocky or sandy
• Rocky is typically more diverse

6
What causes the tides?

• The relative position of the sun and moon
• Moon affects tides on a daily basis
• Pulls on ocean water as it moves around the earth
• Sun has less of an influence seen more
  seasonally
• When moon and sun line up, tides are larger than
  normal (spring tides)
• When moon and sun counter each other, tides are
  lower than normal (neap tides)

7
Variation in tides seasonally

• Neap tides
• Tides are larger than average
• Sun and moon counter each other

• Spring tides
• Tides are larger than average
• Sun and moon lined up

There are many zones on the shore

• Subtidal Never exposed to air due to tides.
• Low littoral (Low intertidal) Infrequently
  exposed to air at low tides
• Mid littoral (Mid intertidal) Exposed to water
  and air relatively frequently
• Upper littoral (High intertidal) Infrequently
  covered by the tides
• Spray zone Never covered by the tides

Meeting site information

• Tide pools at Dana Point, near the Ocean
  Institute
• Saturday May 5 830 am 1130
• Sunday May 6 900 am 1200 noon
• You need to be there for 1.5 hours in that time
• See the handout for more information
• Wear appropriate field clothing
• Shoes/boots/sandals w/heel straps (e..g Tevas)
• Highs 65F may be cloudy and/or windy
• Bring supplies
• Water, sunscreen, snacks, etc.
• While there
• BE CAREFUL
• Watch the waves
• Watch your footing

10
What youre going to do

• Before you go
• Choose 5 organisms to look at
• See the photo guide for help with this
• Do a bit of research into what they look like,
  what they do, etc.
• When youre there
• Spend 15 minutes observing each of your five
  organisms
• Pick one area to look at and note how many are
  there, summarize the behavior of the organism,
  describe the environmental surroundings, and its
  adaptations to the environment
• After youre there
• Write up a formal report
• Turn this in next week
• Follow the instructions in the manual

11
Participation form

• Before attending the trip you need to sign a
  waiver
• Lets do that now!

12
Any questions on the field trip?
13
Plant diversity!

• Last week we looked at a few plant specimens in
  lab
• But we didnt really see all that much
• So today were going to go outside and look at
  real plants
• Complete the worksheet as we tour the campus

14
Before you leave

• Clean up your work area
• Show me your lab report so I can stamp it
• Need to have all data fields filled in
• Complete at home and then turn in at the
  beginning of next lab
• Remember that well have a quiz at the beginning
  of the next class
• 6-7 questions on todays lab
• 3-4 questions on the lab well do next week

15
Notes for the instructor

• I distributed a handout of photographs of common
  intertidal organisms, and let the students keep
  these for the trip. Contact me if youre
  interested in this handout (it consists solely of
  pictures Ive taken at Crystal Cove, so its
  completely distributable).
• As my students seemed to have great difficulty
  understanding the plant reproductive biology
  introduced in the reproduction lab, I replaced
  part of this lab with a tour of horticulture. I
  created my own handout for this, which focused on
  comparing the anatomy and reproductive physiology
  of the four major types of plants (non-vascular,
  vascular non-seed-producing, etc.). Contact me if
  youre interested in seeing this handout.
• Add any relevant cleanup instructions to the
  final slide (that slide is a generic one Im
  adding to each presentation).
• Change the meeting site information as
  appropriate.
