I’m a Meteorologist! Background Information You have been learning all about different types of weather and you know how to record data. Today you will be given a design challenge where you will have to use some of your weather knowledge. Design Challenge You are a Meteorologist for a local TV station. Part of your job is to report on rainfall for the Marietta area. You are to create your own weather rain gauge. You need to test it, measure and record rainfall amounts, and report your results back to the rest of the class. Criteria Your weather instrument must the rain gauge must include a unit of measurement it must work and you must be able to use it accurately be able to be made in the science lab in one class period Possible Materials/Tools: plastic water bottle (1 pint or 500ml) or other container for collecting rain Scissors Markers Tape (masking or duct) Writing tools for data collection Weather recording sheet Units for measurement (inches, cm, Unifix cubes, etc.) Any other items you think you might need for your design Standards Science S1E1. Students will observe, measure, and communicate weather data to see patterns in weather and climate. b. Investigate weather by observing, measuring with simple weather instruments (thermometer, wind vane, rain gauge), and recording weather data (temperature, precipitation, sky conditions, and weather events) in a periodic journal or on a calendar seasonally. c. Correlate weather data (temperature, precipitation, sky conditions, and weather events) to seasonal changes. Math MCC1.MD.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Assessments/Rubrics Student Journals Student Checklist Teacher Observation CRITERIA Your rain gauge must be made out of a plastic bottle (unless you have prior approval from your teacher to use a different container) be able to be made in one class period in the science lab it must work and you must be able to use it accurately there should be visible marks that indicate how much rain there is work in a rainstorm I’m a Meteorologist! Student Journal Name_______________________________________ 1. ASK: What is the problem? State the problem in words. OR draw a picture of the problem and label it. Date_________________________ 2. BRAINSTORM Possibilities What do you already know that will help you solve this problem? Think about the constraints of this challenge. Sketch or describe some possible solutions. Be sure to add labels to your design. 3. CREATE the solution that you think is best. Decide which design is the best possible solution to the problem and determine how you will make it. Write down your design plan step-by-step. 1. 2. 3. 4. List or draw the materials that you will need to complete your design. _____________________________________ _____________________________________ _____________________________________ 4. DRAW and label your final design. 5. Time to BUILD your rain gauge! You will build your rain gauge during your science lab time. 6. EVALUATE your solution. a. Test your design. Measure rainfall for 2 weeks. b. Record your results for each day of the week and the total rainfall for the 2 week period. c. Did your design solve the problem? _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ Did you create a working rain gauge? YES How could you improve your design? What could you do differently next time? Draw or write NO _____________________________________________________________________
