Thar She Blows!

4th grade lesson: Thar She Blows!

Content:

  • This lesson is designed to engage students with an investigation into the mechanisms by which plants are able to distribute seeds.
  • Students will investigate the role of the wind and weather conditions in seed dispersal.

Time Requirement:

  • This lesson is designed to extend over several class periods.
  • During the first period, students will make paper models of seeds typically transported by the wind and investigate the movement of the paper models when dropped with and without wind (air currents are generated by a box fan).
  • Students gather seeds from areas around the school and investigate the means by which the seeds are dispersed.

Data Collection:

  • Data collection will result from the distance the paper seeds travel from the drop point with or without wind. Students will create a data table within their notebooks.

5th grade lesson: Thar She Blows!

Content:

  • This lesson is designed to build upon students’ prior knowledge of seed adaptations for wind dispersal and support students’ understanding of weather and the use of tools to document wind speed.
  • Students will be challenged to construct an anemometer and use the anemometer as a tool to gather and record data on wind speed. Fifth grade students will reflect upon wind speed data to identify pattern and explain dispersal of seeds as a result of wind.
  • Students will build and use anemometers to measure wind speed.

Time Requirement:

  • This lesson is designed to extend over several class periods.
  • Students will investigate the tools used to measure weather conditions including: wind speed, wind direction, air pressure, precipitation, and humidity.
  • Students will construct anemometers to measure wind speed.

Data Collection:

  • Data collection will result from students’ use of their anemometer and other weather instruments to gather weather data over time.
