This past Tuesday, the 5th and 6th grade students joined the Marine Science Institute for a four-hour expedition of the San Francisco Bay aboard a 90-foot research vessel, the R.V. Robert G. Brownlee. The students discovered what lives in the estuary and how we are connected to it. They rotated through three stations using scientific methods and equipment to examine different types of life.
First, they went to hydrology to understand the water quality, and then performed a plankton tow to see the basis of the food chain. After, they used a mud grab to collect a benthic mud sample to look for invertebrates. And lastly, they worked together to deploy a 16-foot trawl net to bring fishes on board. In small groups, they studied the fishes using dichotomous keys. Students were inspired to observe and touch the live animals that they collected. Between sharks, crabs, halibut and sting rays, they saw a bunch of cool marine life!
