Weather Fronts (student-led lesson)


Subject: Earth and Space Sciences 6th grade
State standard: Standard 6.ESS2.6 “Explain how relationships between the movement and interactions of air masses, high and low pressure systems, and frontal boundaries result in weather conditions and severe storms” (Tennessee Department of Education, 2016).
Learning Objectives:
  •          Analyze different types of weather fronts and explain what type of weather is typically associated with each front.
  •          Evaluate current weather fronts and air masses and predict local weather conditions.

Essential Questions:
  •           Why would it be important to be able to predict weather patterns and conditions?
  •           Where do air masses form and how does that impact weather?
  •           How do large air masses and weather fronts affect weather?

Materials:
  •           Computers with internet access
  •          Materials for experiment: 10-gallon aquarium, appropriately sized piece of cardboard, spoon, cold water with blue food coloring, hot water with red food coloring
  •         Weather maps and symbols explained
  •         Graphic organizer worksheet for the explore activity
  •         Guided questions worksheet for the elaborate activity

Essential vocabulary: weather, weather fronts, air pressure, pressure systems, air masses
Previous knowledge:
  •           Students will have previous knowledge of basic weather map symbols
  •          Students will have a general understanding of the basic factors that affect weather

Learning Experience:
-          Engage
o   In order to engage the students, the teacher will perform an experiment simulating weather fronts.
§  Base the experiment off of: when air masses collide
§  Before the experiment, have students hypothesize about what they expect would happen to the warm front and the cold front.
§  After the experiment, have students discuss their observations about what happened when the two “air masses” came together.
§  The teacher will pose the first essential question and elicit feedback.
§  The teacher will then pose the other two essential questions to lead into the explore activity.
-          Explore
o   The students will individually explore a weather front animation and collect information about different weather fronts.

§  weather fronts

§  weather forecasting

o   They will fill out a graphic organizer with the front name, its corresponding symbol, observation of what the two air masses do, and weather associated with the front (Chapel Hill Carrboro City School, 2019).
-          Explain
o   Once students have completed the explore activity, the teacher will ask the students to share their understanding of the different types of fronts and corresponding weather patterns.
o   The teacher will clarify any misunderstandings and introduce additional information by showing several short video clips on air masses and weather fronts to help students visualize the terms being discussed and the interactions that happen between air masses and fronts.
§  Air masses (4:49 minutes)
§  Air masses and fronts (2:22minutes)
§  Meteorologist Ryan Davidson explains weather maps: (3:49 minutes)
-          Elaborate
o   The teacher will then provide regional weather maps, forecast maps, and radar maps for assigned groups of students to analyze. The students will look for patterns and discuss their observations with each other. 
§  NOAA weather forecast maps
§  NOAA radar maps
o   The teacher will provide guiding questions in a worksheet format to help students analyze and compare the forecast and radar maps. (Students can use their graphic organizer to help them understand the maps).
§  Locate a warm front. In which direction is the warm front moving?
§  Locate a cold front. In which direction is the cold front moving?
§  Locate one area that may be experiencing severe storms. What type of front do you notice there? What pressure system is present?
§  Locate one area that is experiencing rain. What type of front do you notice there? What pressure system is present?
§  Locate one area that will likely experience rain for several days. How can you tell?
§  Locate one state that is experiencing clear weather. What type of pressure system is present? Are there any weather fronts in that area?
§  Find your location on the map. What type of front is moving in that direction? What type of weather could you expect when that front moves in? (Boyden, n.d.).

-          Evaluate
o   Students will perform self-evaluations by going to the NOAA weather service page at weather.gov to check the accuracy of their forecasts. They will do this by typing in their chosen city in the “local forecast” box at the top left of the page. 
o   The teacher will evaluate student understanding throughout the lesson by listening to student responses and providing feedback.
Differentiation strategies:
-          English Language Learners
o   The teacher will provide a sheet/website with simple definitions of each weather symbol.
o   For the explore project, the teacher will provide links with text that is matched to the reading level of the student
-          Advanced students
o   The teacher will encourage advanced students to make a 3-day prediction of future weather for a city of their choice based on their analysis of the weather maps.
