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 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.

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?
A CTD — an acronym for Conductivity, Temperature, and Depth — is the primary tool for determining essential physical properties of sea water. It gives scientists a precise and comprehensive charting of the distribution and variation of water temperature, salinity, and density that helps to understand how the oceans affect life
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
It's All About Repetition!
In this lesson, we will learn what repeat photography is, and discuss how it can be used in scientific analysis.
Introduction
What is repeat photography? It is the taking of photographs from the same location, over time, to document changes. This tool has become extremely useful in science, as a qualitative way to
