Curated OER
Relational Causality
Students explore volume and pressure. Through an activity, students discover what happens in situations when volume is increased but no additional air is able to enter the enclosed space. Students create models and explain their...
Curated OER
Ideal Gas Law
Students explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.
Curated OER
Learning Lesson: Go With the Flow
Learners complete experiments with soda cans to examine the effect of pressure and air movement. They create low pressure and discuss its effects. They also examine thunderstorm safety rules.
Curated OER
Learning Lesson: Crunch Time
Students demonstrate the effect of heat on pressure. They use a 2-liter bottle and hot tap water to complete the experiments. They also discuss thunderstorm safety rules.
Curated OER
Learning Lesson: Measure the Pressure -- The "Wet" Barometer
Students use simple objects to create their own barometer. They have five days to build it and ten days to observe and collect data. They examine thunderstorm safety tips to end the lesson.
Curated OER
Learning Lesson: Measure the Pressure II -- The "Dry" Barometer
Learners use simple items to create their own aneroid barometer. They have five days to build it and ten days to observe and collect data. They examine tornado safety tips to end the instructional activity.
Curated OER
Metamorphic Sandwiches - - "Bread Rock"
Young scholars graphically show how metamorphic rock is formed by pressure and heat using bread.
Curated OER
Siphon Pump
Learners determine the basic types of pumps and how they work in terms of pressure, velocity, and elevation differences. They build two examples of gravity-driven water pumps.
Curated OER
Pumps
Students examine the basic types of pumps. They build a gravity-driven water pump and solve a mystery using their knowledge of pressures and pumps.
Curated OER
Wind Tunnel Aerodynamics Problem Set
Students, after reading an explanation from a NASA Web-based textbook, demonstrate an understanding of the text by applying it to the calculation of area, velocity, and pressure in a wind tunnel.
Curated OER
Air Expansion and Contraction
Students observe that air exerts pressure, that heated air expands and that cooled air contracts. After the demonstration, students engage in a question and answer session about what they saw.
