This is a fun activity to explore the science of balance and weight in the classroom. Have the students use the classroom balance scales to see how much items from their pencil boxes weigh. Does it weigh 1 bear, 2 bears, 3 bears, or more?
Trees study- From: I'm a teacher, get me OUTSIDE here! Sorting sticks from longest to shortest. Good outdoor group activity for preschoolers that can be left for individual students to return to time and again.
