Curated OER
Dissolved Oxygen
Students examine characteristics of dissolved oxygen. Given a stream temperature, and stream conditions, students study the relationships of the dissolved oygen in a stream, in organic waste loads.
Curated OER
Dissolved Oxygen
Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.

Create a Quadrant Instructions for Teachers
Students, who are teachers, discover how to make a quadrant in their classrooms. They use the given pattern to make the tool which they would have their students research.
Curated OER
Introduction to the Oscilloscope as a Voltmeter
Students measure the electric potential of 9 volt batteries using oscilloscopes. They draw a diagram of the front panel of the oscilloscope, conduct the experiment, and create a graph of voltage versus the number of batteries.
Curated OER
Using Ion Exchange Chromatography to Separate Proteins
Students explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.
Curated OER
Anatomical Female Reproductive System
Students dissect internal female reproductive organs and take digital pictures that are exported onto a disc for use with power point technology.
Curated OER
Causal Patterns in Air Pressure Phenomena
Students examine why air pressure is hard to notice. They observe the height of a liquid in a tube over time and lift a table with balloons.
Curated OER
Section 1: Non-obvious Causes
Students explore the historical problem of pumping water out of mines.
Curated OER
Passive Causal Agents and the Omnidirectional Nature of Air Pressure
Students study passive causal agents, such as air pressure, in a system. They conceptualize air pressure as passive and omnidirectional, with molecules that make up the air bouncing off surfaces with which they have contact in all...
Curated OER
What is Charles' Law and How Does it Involve Relational Causality?
Students explore how temperature is related to air pressure and introduces students to Charles' Law through the lens of relational causality.
Curated OER
Clean Air
Students observe gas molecules in the atmosphere absorbing the light that goes through them.
