It does require your help and some pre-planning, depending on what your student chooses to demonstrate. Therefore, I will be sending a materials list to each parent, based on what each student chooses. It must be signed and returned to signify your approval of obtaining and/or transporting needed items to school.
For example, if your child chooses to demonstrate tie-dye, you/they will be responsible for obtaining a shirt to dye, dyes, rubber bands, 2 trash bags, etc. If they choose to make puppy chow, you/they will be responsible for obtaining all ingredients, providing mixing bowls, utensils, wax paper, etc.
Other demo speeches that don't include much (if any) "extras" are certainly options, as well. A google search can provide some options. :)
