Before Strategy/Engage: 10 minutes
1. The teacher will write the following words on the board: tornado, shelter, basement, underground, and safe room. Ask students to brainstorm on paper how they think these words are connected. Allow students 5 minutes to brainstorm and write their thoughts on paper.
2. The teacher should call on various students. The teacher can guide students, if needed, to how the words are connected to safety for civilians and how shelters are a way for people to prepare for national disasters like a tornado.
During Strategy/Explore & Explain: 70 minutes
1. Pass out the Pros and Cons Graphic Organizer. Each student should receive three graphic organizers. Show students how to write each type of tornado shelter at the top of the page: Underground Shelter, Part of the House Shelter, and Prebuilt Shelter.
2. Model for students how to find pros and cons of an underground shelter by using the article "Comparing Safe Rooms and In-Ground Storm Shelters" from Rhodes Construction. Put a copy of the article under a document camera in order to highlight the pros in yellow and the cons in green. The teacher should highlight the pros of an underground shelter from the article (ex. cost). Then ask students to find the cons in the article (ex. flooding). Have students call them out as the teacher highlights them in green. Transfer the highlighted information into the graphic organizer. (15 minutes)
3. Ask the students to read the other articles while looking for pros and cons to each type of shelter and writing the information on their graphic organizer as modeled before. (40 minutes)
4. After forty minutes has elapsed, call on students to share their findings. On chart paper or the board, create a large table that lays out the pros and cons of each of the three tornado shelter designs the students researched: underground shelters, part of the house shelter, and prebuilt shelters. The teacher should write the pros and cons of each on the chart paper or board to reflect the student answers. (15 minutes)
After Strategy/Explain & Elaborate: 10 minutes
1. Ask students the following question as an "exit slip" writing prompt: Which design of a tornado shelter do you think is the best to assist citizens with public safety? Do you think there is an alternative design that could be made or a hybrid of the ones already available? Remind students that they may look at their notes of the pros and cons of each design.
2. Students will write the answers on the paper by using both writing and drawings. The teacher should circulate the room as students write, reminding students to reference their graphic organizer.
