I built a website about World War I and then I created this webquest to go along with it. It will take students three days to complete if you want them to go through everything and it includes interesting topics in WWI that I don't always get to in class. The categories on my website include:
Horses of war, truth of the trenches, soldier's stories, medical innovations, the home front, WWI Battles, weapons of war, and the medal of honor.
The link to the site I created is included on this handout.
