Investigate meaningful questions about the water around you
15 Probeware-based guided-inquiry activities
The Teaching Challenge
The Water Quality ImagiLab includes 15 activities designed to encourage students to take an active interest in maintaining and improving the water quality in their local areas.
The PASCO Solution
The activities help students learn about watershed biology, the parameters necessary for evaluating the health of lakes, streams, estuaries, and a variety of methodologies for monitoring water quality. These activities use three measurements that are essential to water quality assessment: dissolved oxygen, temperature and pH—and can all be conducted with just one sensor, the PASPORT Water Quality MultiMeasure Sensor.
How does shade influence water temperature
The enclosed activities are designed to enable students to investigate meaningful questions about water properties and water quality. In the fifteen investigations included in the Water Quality ImagiLab students will be genuinely engaged in inquiry through the use of technology and learn both science content and process

How It Works
About ImagiLabs
ImagiLabs are collections of activities designed to guide student's natural curiosity toward developing an understanding of fundamental science concepts. Each learning activity includes several elements:
Investigating the Question(s)
- Inquiry Question: States the central question the activity addresses.
- Thinking About the Question: Introduction for students and questions for small groups.
- Materials: Lists the sensor, substances, and equipment needed for the investigation.
- Safety: Lists warnings and cautions concerning the investigation.
- Investigation (divided into day by day steps): Provides general guidelines that indicate how to carry out the activity.
Answering the Question(s)
- Analysis Guide: Suggestions for graphs and guidelines for helping students reflect on their collected data.
- Further Investigations: Ideas for extending the investigations.
Teacher Notes
- Introduction: Provides relevance of the lab to both students and national standards -- National Science Education Standards (NRC) and Benchmarks for Science Literacy (AAAS).
- Discussion Guide: Leading questions and possible demonstrations that will help students develop a connection between major concepts.
- Background Information: Further information that enables the teacher to explain or understand the over-riding concepts introduced in the activity.
- Timeline: Suggested guidelines for length of time needed to fully develop the activity.
- Sample Student Report: Provides teachers with a model of completed projects (in PDF format).
Lab Activities
Lab Activities:
- Breathing Underwater -- Can fish breathe better in hot or cold water?
- Oxygenated Waterfalls -- Does the amount of oxygen in the water change in different kinds of streams?
- pH and the Power of Ten -- What pH values are found in consumer products?
- Salting-Out Oxygen -- How does the amount of dissolved oxygen in seawater differ from that found in fresh water streams?
- Buffered Streams and Lakes -- Why does the pH of a stream or lake stay relatively stable?
- Bag an Ecosystem -- How does light affect the pH of an aquatic ecosystem?
- Thermal Pollution -- Is there thermal pollution in your river or stream?
- Biochemical Oxygen Demand -- How much oxygen could your water consume?
- Logging DO Concentration -- How does dissolved oxygen (DO) in a body of water change during a day
- The pH Factor -- How does pH change during a day in a body of water?
- The Shade Factor -- How does shade influence temperature and oxygen levels in a stream?
- Flowing Water -- How does the amount of dissolved oxygen change in pools, riffles, and glides within your stream or river?
- Temperature Stratification -- How does water temperature vary with depth in your lake?
- Probing an Estuary -- What is the pH of your estuary compared to incoming fresh water?
- Probing a Vernal Pool -- How can life exist in a vernal pool?
