It's Our Air - 1-1 What Is Air? WHAT IS AIR? ACTIVITY Through a variety of hands-on experiences presented as stations in the classroom, students will discover properties of air, including that air has volume, mass, and pressure; that it is compressible and that it expands when heated. They will also learn about the major molecular components of our atmosphere (nitrogen, oxygen, argon), the four layers of our atmosphere, and that air contains water vapor. ESSENTIAL QUESTIONS: What is air made of? What are some of the properties of air? How can we demonstrate those properties when air is invisible? Is our atmosphere homogenous or does it change with elevation? TIME NEEDED: one class period MATERIALS: VIDEOS: What Is Air? Part I (included) What Is Air? Part II (included) Video worksheets (included) STATION 1: Molecule sets Transparent jar containing 100 marbles or beads Worksheet (included) STATION 2: Large wide-mouth jar Dishwashing glove Worksheet (included) STATION 3: Two empty glass bottles Balloons Container of hot water Container of ice water Worksheet (included) STATION 4: Large wide-mouth glass jar Water balloons Tea candles Matches Metal tongs Worksheet (included) STATION 5(A): Large wide-mouth jar Hot water Small plate Gallon freezer bag Ice cubes Worksheet (included) STATION 5(B): Two thermometers Fan Small amount of gauze Water Rubber band Sling psychrometer (optional) Worksheet (included) CLASSWORK OR HOMEWORK: Data sheet (included) Graph paper (included) TOPICS: properties of air, components of air, layers of the atmosphere, hydrologic cycle. TYPES: hands-on demonstration, graphing NC ESSENTIAL STANDARDS for Earth/Environmental Science: EEn.2.3.1 Explain how water is an energy agent (currents and heat transfer). EEn.2.5.1. Summarize the structure and composition of our atmosphere. EEn.2.5.5 Explain how human activities affect air quality [video:https://vimeo.com/114136096] DOWNLOAD PART I VIDEO FILE [video:https://vimeo.com/114136097] DOWNLOAD PART II VIDEO FILE WHAT IS AIR? VIDEO Through a two-part video packed with demonstrations and animation, students will discover properties of air, including that air has volume, mass, and pressure; that it is flows, and that it expands when heated. They will also learn about the major molecular components of our atmosphere (nitrogen, oxygen, argon), the four layers of our atmosphere, and that air contains water vapor.
