Science SCI.V.3.2 Strand V : Using Scientific Knowledge in Earth Science Standard 3: Grade: 5 Atmosphere and Weather - All students will explain what causes different kinds of weather Benchmark 2: Describe the composition and characteristics of the atmosphere. Constructing and Reflecting: SCI.I.1.1 - Generate scientific questions about the world based on observation. SCI.I.1.2 - Design and conduct scientific investigations. SCI.II.1.1 - Evaluate the strengths and weaknesses of claims, arguments, or data. Vocabulary / Key Concepts Context Composition: • air • molecules • gas • water vapor • dust particle Examples of characteristics of the atmosphere: • steam • pressurized cabins in airplanes • demonstrations of air pressure Characteristics: • air pressure • temperature changes with altitude • humidity Examples of air-borne particulates: • smoke • dust • pollen • bacteria Effects of humidity: • such as condensation • dew on surfaces • comfort level of humans. Knowledge and Skills The students will identify and explain the composition of the atmosphere, discussing molecular components like water vapor and other gases. Characteristics of the atmosphere will be summarized using examples such as air pressure, temperature changes and humidity.

Vernier probes available: Relative Humidity, Barometer Instruction Assessment Focus Question: What is water vapor/humidity and how does it affect weather? Optional Assessment: Assessment II (JCISD) The Clooneys took a car trip across the United States, from their home in San Francisco to New York. The fog was really heavy when they left San Francisco. Fog in the air means that the air contains more: a. dust particles b. ozone c. water vapor d. acid rain One activity to show water vapor/humidity is to use 2 tablespoons Cobalt Chloride to one pint of water solution. Coffee filters are dipped into the solution and hung to dry. Students should then cut the coffee filters into a cloud shape. Students place “coffee filter cloud” in their bathroom at home and observe the color of the “cloud” before they shower, then again after they shower. Students record observations. (The cobalt chloride will show red with the presence of water. It will be blue when the air is dry.) Assessment I Students will build models to show variations in air pressure or humidity. They will work with the model to explore and collect data on the properties of air. They will write their observations and conclusions from the investigation. They will relate their work to another application such as hot air balloons, temperature variation at the top and bottom of a mountain, and pressurized cabins on an airplane. (Scoring rubric in teacher notes – give to students prior to activity) The drive along the New Jersey coastline was beautiful. They began to perspire heavily as they walked along the beach. The humidity was very high. This meant that which gas molecules were most present in the air? a. smog b. water vapor c. acid rain d. industrial emissions As they drove up into the Rocky Mountains, the Clooney’s ears began to pop. Then when they got out of their car to walk to a scenic view, they all noticed that they were breathing more heavily than when they walk in San Francisco. This was due to: a. b. c. d. low pressure and high temperatures high altitude and low humidity high altitude and low pressure high humidity and high temperatures Teacher Notes: The atmosphere is a mixture of nitrogen, oxygen, and trace gases that include water vapor. The atmosphere has different properties at different elevations. (NSES) Focus Questions • • What gases compose the atmosphere and why are they important? What are their characteristics?
