![]() ![]() After allowing time for reports, tell them that, although their ways are good and that they will have time to try out their ideas, you are going to show them how to make three instruments that they will be using in this unit. The groups will come up with different solutions to the problem that was posed (for example a group might decide to hold a long paper streamer straight up in the air and the direction that it points will tell them something about wind direction). Gather groups together to report on their ideas. What kind of container would be good for collecting rain?Īfter a brief discussion, divide students into groups and have them brainstorm things or designs for things that they could use to measure wind, precipitation, and temperature.How can we tell how fast the wind is blowing?.How can we tell from which direction the wind is blowing?.Tell them that, although thermometer will be provided, they have the task of constructing the other instruments themselves Refer to the list (generated in Activity#3, Lesson #1) of weather attributes that they would like to study.They will not be making entries in their "official" weather log until Lesson#3. ![]() They can be completed on separate days or after they have constructed all of the instruments. Note: The practice activities below are suggested to familiarize the students with the instruments. The thermometers should be purchased the students will make the other weather instruments. Since it would be impractical for the students to leave their instruments outside for the duration of the unit, each group will keep in a box its own thermometer, anemometer, wind vane, and rain gauge and take it outside with them each day. Students should be divided into groups of three or four and work in these groups throughout the length of this unit. Inexpensive outdoor thermometers can be purchased from school supply companies or may be brought in from home. The materials needed for the construction of the rain gauge, wind vane, and anemometer are listed on the Directions for Construction Page for each. Time: Approximately three hours spread over a one week period.
