Students will use weather trends to determine planting dates.

Estimated Time

45 Minutes

Setting Required



  • S4E4. Students will analyze weather charts/maps and collect weather data to predict weather events and infer patterns and seasonal changes.
    • b. Using a weather map, identify the fronts, temperature, and precipitation and use the information to interpret the weather conditions.
    • c. Use observations and records of weather conditions to predict weather patterns throughout the year.


  • Large outdoor thermometer
  • Rain gauge


  1. Remind students that most plants like to grow when there is not a threat of frost (which occurs at 32 degrees Fahrenheit).

  2. Challenge students to determine when it’s a good time to plant a spring garden based on weather data they’ve collected it (if it is spring time) or based on historic weather data (from sites like:
  3. Check student guesses with resources like the farmer’s almanac for the average last frost date or other local growing guides from organizations like extension agencies or master gardeners.
