Biofilms and Biodiversity
Students get first hand experience with Chesapeake Bay biodiversity
and the micoorganisms that develop suitable habitat. The program
will help students and teachers understand the role that biofouling
communities play in relationship to water quality by using an
innovative sampling system that incorporates acrylic discs and
performing analysis via the WWW. The project will increase the
ability to rapidly monitor and identify the organisms that attach
to the discs as another way of monitoring water quality. This
information will be shared with our VIRTUE Project partner schools
in Goteborg, Sweden, and Bergen, Norway, making this a global
and collaborative project. |

DNA Extraction Lab
Following an introduction to DNA, students will have an opportunity
to extract DNA from some interesting cell samples like horseshoe
crab blood, salmon sperm, bacteria, and some common vegetables
or fruits. Some samples will be prepared ahead of time while
others will be prepared by the students. The students will then
compare their DNA extractions to positive samples. The steps
are not complicated but do require that students work with the
idea in mind of optimizing the yield of DNA product that they
are attempting to extract. The experiment introduces students
to the use of fundamental lab equipment and the process of gel
electrophoresis of DNA samples. |

Natural Products and Biosensors
Students learn about the development and research behind microbial
biosensors. Students are able to prepare extracts from marine
algae and other plants, test the effectiveness of the extract
on a bioluminescent bacterium, and make conclusions about their
experiment based upon their hypothesis regarding their extract
in comparison to the results from other groups. |

Oil Pollution: A Soapy Solution
Students will investigate the ability of biosurfactants
to emulsify motor oil by attempting to remove oil from sand
and false fur that has been contaminated with oil. The techniques
and methods utilized by the students increase their awareness
of the process of emulsification by biosurfactants and what
value it may have for environmental problems regarding oil
pollution. |
|
Enzyme Function Lab
Students will explore and investigate the specificity of
enzymes. Test a lactase enzyme for effectiveness on its
substrate while changing the pH and temperature of its environment.
Discover what you know about enzymes used in everyday products
and how enzymes are used in biotechnology research. |

Oysters
After an inquiry about the eastern oyster and a review of background
information with the SciTech staff, students will generate a
list of questions they have about the eastern oyster. Student
investigations will be preformed in the SciTech Student Research
Laboratory. Students will work with a live oyster to observe
and understand the relationship oysters have with other invertebrates,
oyster anatomy, the process of filtration of food and non-food
particulate matter, and the techniques used to identify disease-causing
microorganisms. In addition, a Center of Marine Biotechnology
(COMB) scientist will discuss his or her research, personal
science career path and respond to student questions about possible
careers in science. |

Plankton in the Bay
In the lab students will use the Olympus America microscope
equipment to get a better view of the plankton so they can learn
about the different species and estimate populations from the
Inner Harbor water. The lab will help students understand the
dynamics between nutrients, springtime algae blooms, and zooplankton
population growth. Students will explore the environmental factors
that favor plankton growth and reproduction in the Bay and how
their populations are dependent upon key nutrients like nitrogen
and phosphorus. Fundamental math applications to estimate plankton
populations will help students understand the role of math and
sampling in the environment. In turn, the research conducted
at COMB that focuses on the link of zooplankton to vectors of
human disease will be described and demonstrated. |

Zebrafish Embryology
Students learn about developmental biology by collecting and
observing newly fertilized zebrafish eggs. Students observe
zebrafish development at varying temperatures and record data
as the embryos rapidly develop from 2 cells to over 1,000 in
just three hours! The speed of zebrafish development provides
researchers with a powerful model useful in studying gene function
in Striped Bass. Students will learn to stage cells and will
design experiments to observe the effect of very small temperature
changes on the rate of development. |

Grade 3-5 Program - Looking at the Chesapeake Bay
The grade 3-5 program is called Looking at Chesapeake
Bay. During their two-hour visit the students get a chance to
gain an understanding of the ecology of the bay by using different
field and laboratory equipment. One activity involves the hands-on
use of different devices used to collect water samples and plankton
from the bay. Inside, the participants put on lab coats and
get a chance to try different lab activities. They involve using
Olympus America microscope equipment to look at different Chesapeake
organisms while they are alive. The focus is practicing the
use of the microscopes with activities that include feeding
sea anemones, identifying different types of mud crabs using
a simple key, and looking at the plankton that the students
collected while they were outside. With the equipment the students
all get a chance to get a take home a photo of something that
they enjoyed looking at under the microscopes. Other activities
include holding a periwinkle snail and a scavenger hunt looking
for different bay creatures that are maintained in the lab.
The latest additions to those organisms are thirteen diamond
back terrapins that are a part of a Department of Natural Resources
program. This gives the students a chance to see and participate
in a threatened species restoration project.
