Wax Museum information letter that can be sent home. 2nd grade at my school does a wax museum every year. Each child gets to pick someone to dress up as and complete some research on. On the day of the wax museum, students will have completed research, created a 3-5 sentence speech, a timeline of 5 events and have brought a costume from home to wear. They will give their speeches at their desks in front of parents and other students.
