Joining the War Effort, One Peach Pit at a Time

by Rebecca Furer for Teach It


Historical Background

World War I was the first conflict to see large-scale use of chemical weapons. Poison gases, such as chlorine, phosgene, and mustard gas caused blisters on the skin, blindness, lung damage, asphyxiation, and other injuries. The earliest German gas attack (at Ypres, France, in 1915) took the Allied forces by surprise, and soon afterwards the British and French started developing their own chemical weapons and protective gas masks. The United States ramped up its gas mask production in 1917–1918. The Red Cross spearheaded a campaign to collect fruit pits and nut shells for making gas mask filters. Several factories in Connecticut converted to gas mask production in order to meet the army’s needs. Hundreds of women in the state were recruited for this work.

D1: Potential Compelling Question

How does an entire society participate in war?


  • To what extent were women essential to the workforce during World War I?
  • How did the U.S. government and the Red Cross mobilize people to participate in the war effort?
  • In what ways did Connecticut industry influence World War I?
  • How did Connecticut’s existing industrial infrastructure and workforce adapt to serve the war effort?


Things you will need to teach this lesson:


  1. Start by displaying the “Peach pit hogshead” image, preferably full screen, without the title/caption.
  2. Ask students to look closely at the image and share what they see. Encourage them to back up their comments with specific visual evidence. Ask, “What do you see that makes you say that?” You may want to use the Library of Congress Analyzing Photographs & Prints process (download Teacher’s Guide) to guide students’ looking. Assemble a list of questions that arise from the students’ examination of the photograph.
  3. Next, display or distribute the advertisement for Murray’s Boston Store in Willimantic. Once students have had a chance to read the advertisement, make a list of the new pieces of information students have gathered. See which questions from the initial list have now been answered, and make a list of additional/new questions.
  4. Select one, two, or all three of the short newspaper articles to share with students. You may wish to assign different articles to different students or have everyone read all of the articles. Ask students to:
    OBSERVE: What information can they gather from the articles?
    REFLECT: What do they think based on what they have read?
    QUESTION: What does this article make them wonder?
  5. You may want to use the Library of Congress Primary Source Analysis worksheet to help students organize and record their thoughts.
  6. Look back at the students’ list of questions for inquiry and/or at the suggested supporting questions. Discuss to what extent these primary sources help uncover answers to those questions or to the larger compelling question. Discuss additional questions the students have and sources or avenues for further inquiry.

  • Drawing on their examination of the primary sources in this activity and other related sources (see below for some suggestions), students will design a World War I-style poster promoting the collection of fruit pits for the war effort OR encouraging women to take on war work in Connecticut factories. Need inspiration? Check out the Library of Congress’s collection of World War I Posters.
  • Students will research other Connecticut industries during World War I and compare them to the production of gas masks at the time. Who was employed? Where were the factories located? How did the products contribute to the war effort? Did the factories make something different before the war?
  • Students will draft a letter to a state legislator or to the editor of their local newspaper advocating why—based on the study of history and the examination of primary sources—there should be a monument that recognizes the war efforts of Connecticut residents on the home front during World War I.
