                                      The Tide Pool Studies (12 points)
In the 3 tide pool studies you will be determining some of the abiotic factors that affect the life in these pools
and you will be identifying the various species of plants and animals associated with the pools. You will also
need to check the ocean temperature, salinity(saltiness), and possibly the pH of the ocean water to do
comparisons.

9:50 am -.Collect your abiotic data about the ocean. Try to get a thermometer to record its temperature and
record its pH if you have some pH indicator paper. If you do not then you should try to get this data from other
groups that had equipment. All students should do a taste test for salinity or collect a small amount of water
directly from the ocean to do salt-taste comparisons with the tide pools.
DATA from Step 1: Time of day:_______________ Ocean temp.____________ pH______________

10:30 am-. Upper Shore Tide Pool Study: Walk back up the beach and choose a tide pool somewhere in the
upper shore area. Try not to disturb it too much while you conduct your studies. Collect the data on the abiotic
factors first and then determine how many species of plants and animals inhabit that pool.

11:15 am -12:00pm Middle Shore Tide Pool Study and Treasure Hunt ( see page 3): Walk down the beach
and choose a tide pool somewhere near the rocks draped with rockweed (Complete Rockweed study page 5
and Barnacle study page 6). Again try not to disturb it too much and collect the data on the abiotic factors first
and then determine how many species of plants and animals inhabit this middle shore pool.

rockweed area, in the lower tide zone. Collect your data and record below.

COMPARING THE TIDE POOLS: How the pools are similar, and how they are different.
A. Look at the abiotic factors that are different between the 3 tide pools and explain why these differences exist
from pool to pool: ________________________________________________________________

variations would occur from pool to pool: ________________________________________________

TREASURE HUNT: Use the pictures below as a guide to find and identify as many plants and
animals as possible. Put a circle around the ones you find. (Value 8 points)_________________




                                                                                            4
                                ROCKWEED STUDY (5 points)
The two main types of rockweed at the rocky shore are Fucus vesiculosis (commonly called
rockweed) and Ascophyllum nodosum (commonly called knotted wrack). These two species
often grow together on the rocks in the intertidal zone. In our Atlantic area these seaweeds are
taken off the rocks and sold to companies to extract powders containing algin which can be
used as a gelling agent in many foods and substances. The agar we used in our microbiology
studies would contain algin that causes the agar to gel.




1.Use the sketches above to help you find these 2 common types of seaweed. Describe each.
(color, average length, special structures, its root-like structure, symmetry, texture, weight, etc.)

2. Look through and under the piles of seaweed to find organisms that may be hiding. Report.

_____________________________________________________________________________

4. Fucus vesiculosus (rockweed) contain reproductive structures at their tips. The male plants
   release sperm while the female plants release eggs. Eggs and sperm will unite in the water to
   form zygotes. Cut open the tips to see if you can see the difference between the males
   (orange-colored) and the females (olive-green color). Report your findings on the back of
   this sheet.
5. Draw a sketch of each of these seaweeds. Provide a title, labels and signature.

                                                                                                    5
                                BARNACLE STUDY (5 points)

Barnacles are sessile animals that are related to common crustaceans such as lobster, crab and
shrimp. When water covers barnacles they open their shells and begin to feed by sweeping the
water with jointed appendages. When the tide goes out the barnacle closes up except for a small
hole called a pneumatophore.

1. Find a small rock that has a few barnacles on it and place the rock in a shallow tide pool to
    watch the barnacles feed. You can also try to cut a larger barnacle from a rock and place it in
    a small container with ocean water. The barnacle should soon begin to feed.
2. Describe the moving structures and activity you see as the barnacle feeds. Use a magnifying
    glass if you have one. ________________________________________________________

4. When the tide goes out how do barnacles protect themselves from various factors that would
kill them? Identify the various factors and explain how the barnacle is protected. ____________

                      COMPARING TWO ORGANISMS (6 POINTS)

Place 2 or 3 interesting organisms in your larger bucket with materials to form a temporary
aquarium. Do a detailed study of two of the more active animals. Use a magnifying glass if
you have one. Describe movement, behavior, structures, similarities and differences. Also try to
sketch and label both organisms. Good luck!
