Concept note-1: -The federal government encouraged Americans to conserve and recycle materials such as metal, paper, and rubber, which factories could then use for wartime production. Lots of everyday household trash had value: kitchen fats, old metal shovels, even empty metal lipstick tubes.
Concept note-2: -At home, buying war bonds or savings stamps was probably the most common way to support the war. When people bought a bond or a savings stamp, they were lending money to the government. Their money would be paid back with interest after the war.
Concept note-3: -As the U.S. military recruited young men for service, civilians were called upon to do their part by buying War bonds, donating to charity, or, if they worked in industry, going that extra mile for the troops.
Concept note-4: -United States Food Administration In August 1917, the federal Food Administration began taking measures designed to conserve food for the war effort. Americans were asked to reduce their consumption of wheat, meat, sugar, and fats in particular.
Concept note-5: -Supplies such as gasoline, butter, sugar and canned milk were rationed because they needed to be diverted to the war effort. War also disrupted trade, limiting the availability of some goods.
