1 Air and Weather FOSS kit 2. E. 1 Understand patterns of weather and factors that affect weather. 2.E.1.1 Summarize how energy from the sun serves as a source of light that warms the land, air and water. 2.E.1.2 Summarize weather conditions using qualitative and quantitative measures to describe: Temperature Wind direction Wind speed Precipitation 2.E.1.3 Compare weather patterns that occur over time and relate observable patterns to time of day and time of year. 2.E.1.4 Recognize the tools that scientists use for observing, recording, and predicting weather changes from day to day and during the seasons. 4 Investigations: Exploring air and pressure; measuring weather; wind explorations; long term weather explorations Purpose: Develop curiosity about air and weather. Enough materials for 2 classes of 32 students in each kit Air and weather journal for each student; important assessment component Letter to parents Investigation 1 Exploring Air; Part 1 Air is There 2.E.1.2 Observe properties by observing how air interacts with different objects Materials: balloon pumps, round balloons, zip bags, flex straws, cotton balls, plastic foam balls, feathers You provide: scissors, scrap paper Cut flex straws in half and save the flexible end for this activity What is air? What can it do? Introduce the bag contents; find out all they can about air by using their materials in the bag Rules: nobody blows the balloon in their mouth use balloon air pump; cannot let go of balloon; do not use straw to blow into other peoples faces Cleanup: Foam balls and feathers go back in the kit; students may keep the rest Draw or write what they know about air already 1

7 Meteorologists use several tools to observe the wind. A wind scale describes the strength of the wind. Anemometers measure the speed of the wind. Wind vanes are used to observe the direction of the wind. Investigation 4 Looking for Change Part 1 Weather Graphs 2.E.1.4, 2.E.1.3 Look for changes of weather; organize information gathered on the class weather chart over the past month Duplicate a copy of Weather record; attach symbols of class weather record and duplicate one for each student; 1-2 copies of graph; students cut symbols apart and construct graph of weather; make predictions of next month; easy to see information when organized on a graph Investigation 4 Looking for Change Part 2 Comparing the Seasons 2.E.1.4, 2.E.1.3 Monitor temperature, weather and rainfall on seasonal charts throughout the year Use rain gauge made from 2 liter bottle (same instrument without funnel works well for snow) Glue 2-3 copies of the weather graph end-to-end; cut strip from category sheet and attach to the bottom row; Label graph conditions ; Temperature record made in the same way; rainfall gauge should also have strips of blue construction paper and tape/scissors near the chart Ongoing investigation: Observe sun moving across sky. Look at newspaper weather and ask why there are high and low temperatures given for each day. Each day at specified time, class meteorologist makes an X on temperature graph and conditions graph; if rain, take blue strip of paper, hold against rain gauge and cut a strip to the size necessary to represent the height of rain in the gauge; placed temporarily on the today column, later being moved to the total for season; keep graph for each season; compare graphs for each season. Look for temperatures and conditions that are characteristic for each season Investigation 4 Looking for Change Part 3 Night Sky This is not a part of the Essential Standards for grade 2. I would omit this portion of the kit. 7
