That is unusual because I usually change the apparatus weekly. Sometimes I will leave an apparatus up for two weeks, but then something would be added the second week to change the configuration. Instead of changing the apparatus these past three weeks, I changed what was in the table and the accompanying provisions.
The first week was snow with scoops, containers and people for a Snow Park. The second week was snow with paint and paint brushes for Painting Snow. This past week, objects frozen in ice were added to the table. In addition, wooden hammers, tongs, goggles and table knives were available on the shelves next to the table for the children to use.
