We had a number of small pumpkins in our classroom in the days leading up to Halloween.  We placed some of the pumpkins with a selection of gourds at our art centre.  Students were invited to select a gourd/pumpkin to sketch and paint.  The art was displayed on our new artist bulletin board in our classroom, and on our hallway bulletin board.  At our science table, we placed the pumpkins with a variety of tools for our students to explore.  On this day, we put out a balance scale, mirrors and magnifying glasses.  Our students were invited to find an answer to the question, "Which pumpkin weighs the most?"
