FOULING LAB• GROUPS OF 3:

YOU WILL NEED:A Clipboard with the field sheet

NO BOOTS TODAY:

Now that we are back….

• Drop our animals in the tanks• Return clipboards to the drawers• Make sure to turn in your data

sheet.

• Open up to PAGE 9 of your NOTES

• BIOLOGICAL STRESSES influence what can live on the dock. What is a BIOLOGICAL STRESS?

USE YOUR NOODLE!!!

• BIOLOGICAL STRESSES can be grouped into two categories: BIOTIC and ABIOTIC. What do these terms mean?

USE YOUR NOODLE!!!

DOCK ABIOTIC AND BIOTIC FACTORS NOTES PAGE 19:

BIOTIC FACTORS:

ABIOTIC FACTORS:

USE YOUR NOODLE!!!• What observation did you make about the

amount of space available for organisms on the dock?

DOCK ABIOTIC AND BIOTIC FACTORS NOTES PAGE 19:FACTOR BIOTIC or ABIOTIC?

SESSILE

MOTILE

SPACE IS HARD TO COME BY…

USE YOUR NOODLE!!!• What activity did the barnacles spend most of their

time doing? What does that tell you about the availability of food in the dock community?

DOCK ABIOTIC AND BIOTIC FACTORS NOTES PAGE 19:FACTOR BIOTIC or ABIOTIC?

BARNACLES FEEDING…

USE YOUR NOODLE!!!Organisms found on the dock are often referred to as FOULING organisms. Given what you know about the word fouling (foul ball, a foul smell etc) what effect do you think these organisms have on the areas to which they attach?

Fouling Organisms damage

WARMUP!!!• GROUPS OF 2:– Logon and open up excel. Go to class website and

download class data from the dock lab.

• GRAPH DATA FROM YESTERDAYAnswer the questions that

follow:

YOU HAVE 25 MINUTES!!

• We know that FOULING organisms are potentially damaging to boats and pilings. What kind of damage could they cause?

USE YOUR NOODLE!!!

USE YOUR NOODLE!!!• Damage to boats and pilings by fouling

organisms is estimated between 10-15 million dollars a year. How can this damage be prevented or mitigated?

ONE SUCH EXAMPLE…

PROJECT: Design A Dock!!!• GROUPS OF 1: Design an Anti-fouling Dock Technology– Must be New (It CANNOT be pre-existing)– Include a Detailed Drawing of HOW your technology works.– Consider the ENVIRONMENTAL Impact– Consider the FINANCIAL Impact– Consider the INSTALLATION and EASE OF USE
