Making Connections: Pressure, Temperature, & Volume

8th Grade Physical Science Module Overview

Topic: Pressure, Temperature, & Volume

Grade Level: 8

Course: Critical Thinking Science – Middle School

Time Allotted: 13 days

Prior Knowledge: Students should have basic algebra, graphing, and spreadsheet skills.

Overview: Students will first be introduced to temperature, exploring the concept and building their own thermometer. Students will then be introduced to pressure through activities, demonstrations, and an experiment comparing pressure and temperature. They will construct and use their own barometer. Next, students will be introduced to the concept of volume and the relationship between pressure, altitude, temperature and volume, describing the relationship using an equation. Finally, in the culminating activity, students will design a travel itinerary for a visiting alien with a flexible body. The students will calculate the alien’s volume at different locations on Earth, taking into account pressure, temperature and volume effects, including Charles’s law and Boyle’s law.

Vocabulary

Barometer: An instrument used to measure atmospheric pressure

Conversion: Moving between different units of measurement for the same quantity

Manometer: Instruments that use liquids to measure gas pressures that are close to atmospheric pressure

Pressure: The amount of force acting on a unit area

Volume: How much three-dimensional space a substance occupies. For containers, it is the amount of fluid they could hold.

Materials

•  All students should have their own science notebooks for ALL activities
