Through investigation, you will determine which solution has the highest density.
Objective
To determine, through experimentation, which of a variety of solutions has the highest density.
Preparation
Background: The waters of the ocean are constantly moving in many different ways. The surface of the ocean rises and falls in rhythm. These movements, in the form of
Students complete a physical puzzle based on a scientific poster about Bowhead Whales. Students then research the content of the poster and present their findings.
Objective
To familiarize students with:
* the scientific method
* real polar scientific posters
* real polar scientific research
* real polar scientific terminology
* real polar scientific technology
* real polar
Students are designated as the water or ocean currents, zooplankton, and bowhead whales. The zooplankton are informed that they are at the mercy of the currents. The currents are given instructions as to where to go during different times of the year (map). The whale pod is told that they need to breathe (raise hands above head to indicate
Students will build a simple plankton net from a nylon stocking, then (optionally) use it to collect plankton in ponds, lakes, streams, bays, oceans, or even aquariums.

The Center for Microbial Oceanography offers resources on education and outreach for K-12 teachers, undergraduates, grads & post-docs and related links. This is a great tool for lesson planning. In addition to outreach ideas, C-MORE offers kits for review and request.
Since most plankton is smaller than we can see, they must be looked at using a microscope. They are usually strained from the water using fine mesh nets or sieves with tiny holes. Typical plankton nets have a round opening and look like a funnel that leads into a collection bucket at the end of the net. The nets are
One of the simplest biological samplers, zooplankton nets are made in a wide variety of styles and sizes. The two nets in the MARMAP Bongo vertical-haul net system explained here each have a mouth diameter of about 25 cm.
What is it and why do we use it?
An Acoustic Doppler Current Profiler, or Acoustic Doppler Profiler, is often referred to with the acronym ADCP. Scientists use the instrument to measure how fast water is moving across an entire water column. An ADCP anchored to the seafloor can measure current speed not just at the bottom, but also at
Arctic Ocean Biodiversity is a Census of Marine Life project aimed at coordinating research efforts examining the diversity in each of the three major realms: sea ice, water column and sea floor, including fish, mammals & birds. This program will consolidate what is known and fill remaining gaps in our knowledge: it leads the Arctic Ocean diversity cluster within the
