Saint John High School

Today students from Saint John High School were here at the Huntsman Marine Science Centre as part of their grade 11 Biology class. These students went on the boat to collect plankton and invertebrate specimens and also studied various species of phyto and zooplankton under the microscope. In the afternoon the students classified a number of benthic marine invertebrates as well as took a closer look at the feeding rate of barnacles at temperatures between 5 and 25 degrees Celsius.

 
Students head for cover as we begin the scallop drag. For safety reasons students may not remain on the deck while the winch is being operated.

 
Students examine a scallop and a sea peach found in the scallop drag.

 
Students enjoy the sunny ride back to the dock.

 
Students carefully catalogue different traits of each marine invertebrate to aid in identification.

 
Water baths are used during the barnacle feeding rate experiment.  The fresh water ice in the outside bowl cools the salt water in the inside bowl.

 
These girls are carefully monitoring the temperature of their water so that it does not get to hot or cold.

 
If you look closely you can see the cirri, jointed appendages of the barnacle, sweeping through the water as it feed.
