This unit provides an activity for the use of
the PASCO interface and an absolute pressure sensor within the Fluids unit of
the APEF Science 8 curriculum.
Learning Level: Grades 7-9Author(s): Nancy Chisholm
What happens to the pressure on air when the volume is altered?
APEF Science 8 Curriculum outcomes addressed in this unit:
Explain qualitatively the relationship among pressure, volume, and temperature when liquid and gaseous fluids are compressed or heated (309-4)
Describe the science underlying hydraulic technologies (111-5)
Science classroom, in groups.This should be carried out as one activity of several taking place in the classroom simultaneously. Students will spend up to 20 minutes at the computer, in pairs or groups of three to carry out the activity and to respond to the questions.
Use the computer, DataStudio software, and the PASCO interface with Absolute Pressure sensor.
Run the DataStudio Workbook activity titled "tightsqueeze.ds" and follow the instructions provided.
Analyze results and make predictions.APEF Science 8 curriculum outcomes:(309-4)
Explain qualitatively the relationship among pressure, volume, and temperature when liquid and gaseous fluids are compressed or heated(111-5)
Describe the science underlying hydraulic technologies
Students will work in pairs or groups of three.
Several stations of activities related to the unit (Fluids) should be set up.
If there is enough equipment, each computer of the pod could be set up with this activity, including a copy of the file: "tightsqueeze.ds"
Students open this activity through DataStudio, and follow the instructions on each page of the workbook.
They are to collect the data at the appropriate section, and respond to the questions in the following pages.
At the end of the activity, students are to save their work for the teacher to review.
Collaboration and group skills (Rubrics available through the textbook materials)
Responses to questions
Plans for further investigation provided
Computer with DataStudio software
Pressure (Absolute) sensor
20 mL syringe with connector to sensor
Workbook file: tightsqueeze.ds
The tightsqueeze.ds file includes instructions for students to save their work using a different name. This new file will be used for evaluation and assessment.
