Biocomplexity Lab Activity: Measuring Turbidity

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

In this aquatic organism learning exercise, students measure the pH of household solutions and of pond water samples. They compare these to tolerance charts for aquatic macro-invertebrates to complete 5 charts or short answer questions.

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Students are introduced to careers with an aquatic emphasis. They take a self-evaluation test on what they enjoy in school to determine which career is right for them. They listen to people in the field discuss what their job is like.

Students measure the clarity of a body of water and identify possible environmental complications that can be attributed to clarity and turbidity.

JASON Aquatic Field Study: Use water temperature, turbidity, and dissolved oxygen data collected by researchers to examine the quality of an aquatic site using a TI-73 Explorer to graph and analyze the values and determine its water...

In this activity, students' use a pH sensor and Temperature Sensor to measure and compare the pH and temperature of three aquariums over a period of several weeks. They will compare and understand how plants and animals affect the water...

For this activity, students visit a local stream over a 9-week period to take measurements of its chemical and physical attributes, and collect information about the life forms it supports. After exploration, they will choose what they...

Learners explore the health of aquatic life in this science instructional activity They measure and track the oxygen level in the water to determine the health of the aquatic life. They collect this data using the TI explorer to graph...

Learners test their local aquatic site to determine its water clarity. They collect a water sample and measure its turbidity using a sensor, then they repeat the experiment to obtain a second turbidity reading to find the average value.
