The Tide Pool Studies
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. Record the ocean temperature, salinity(saltiness), and pH to do comparisons.
Leader Name: ______(A)
9:50 am– Go directly to the ocean and observe the living organisms you can see in the water. This is called the ______zone.Collect your abiotic data about the ocean. Get a thermometer to record its temperature and record its pH with the indicator paper. 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.
ABIOTIC DATA from Step 1:
Time of day:______Ocean temp.______pH______
BIOTIC DATA for observations in the ocean water:
How many different species of plants are living in the observable ocean zone? ______
LIST the identifiable ones: ______
How many different species of animals are living in this area? ______
LIST the identifiable ones: ______
Leader Name: ______(B)
10:15 am. 10:40 am –Low Tide Zone Pool Study: Walk along the beach and choose a tide pool below the rockweed area, in the lower tide zone. Collect your data and record below.
ABIOTIC DATA for lower tide pool:
Time of day______Air temp.______
Approximate wind speed______km/h
Tide pool temps. Top______Bottom______
Pool dimensions: Depth______Length______Width______pH______
Salinity of pool(Less salty, more salty or the same as the ocean)______
BIOTIC DATA for lower tide pool:
How many different species of plants are living in the upper tide pool? ______
LIST the identifiable ones: ______
How many different species of animals are living in this upper tide pool? ______
LIST the identifiable ones: ______
Leader Name: ______(C)
10:40 am -11:05 am 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.Try not to disturb the organisms in the pool.
ABIOTIC DATA from middle tide pool:
Time of day______Air temp.______

BIOTIC DATA from middle tide pool:
How many different species of plants are living in the upper tide pool? ______
LIST the identifiable ones: ______
How many different species of animals are living in this upper tide pool? ______
LIST the identifiable ones: ______
Leader Name: ______(D)
11:05 – 11:30 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.

Complete Barnacle study (See page 7) Quadrant Study (See page 8)
DIAGRAM OF THE INTERTIDAL ZONE
Draw a diagram of the 3 zones of the intertidal zone at low tide so that all 3 beach areas are shown. Label each area and provide a list of 4 representative species for each zone.
Leader Name: ______(C)
Leader Name: ______(D)
COMPARING THE TIDE POOLS: How the pools are similar, and how they are different?
A. Consider the abiotic factors that are different between the 3 tide pools. Explain why these differences exist from pool to pool in detail: ______
______
B. Compare the varieties and numbers of plants and animals that exist in the 3 different pools. Explain with detail why variations would occur from pool to pool: ______
______
C. Describe theabiotic and biotic similaritiesbetween the 3 tide pools.
______
______
Leader Name: ______(A)
ROCKWEED STUDY
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.
- Use your index cards to help you find these 2 common types of seaweed. Describe each in detail. (colour, average length, special structures, symmetry, texture, weight, etc.)
Rockweed - ______
______
Knotted wrack -______
______
- Look through and under the piles of seaweed to find organisms that may be hiding. Try to identify any observed critters using your index cards, and list below.
______
- Fucus vesiculosus (rockweed) contain reproductive structures at their tips. The male plants release sperm while the female plants release eggs. 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 observations below.
- Draw a sketch of each of these seaweeds. Label major parts (holdfast, stipe, blade etc).
Rockweed / Knotted wrack
Leader Name: ______(B)
BARNACLE STUDY
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.
- 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.
- Describe the moving structures and activity you see as the barnacle feeds. Use a magnifying glass if you have one.
______
______
3. What is in the water that the barnacle is trying to catch?______
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. ______
5. Below draw a sketch of a barnacle feeding. Label the parts of the barnacle.
Quadrant Study: Using your string to measure out a 1 m2 area. Identify and count the specimens in the quadrant. This must be in the MID TIDE ZONE.
Organism / Count # / Trophic levelTREASURE HUNT: Use the pictures below as a guide to find and identify as many plants and animals as possible. Circle the ones you actually find!
