Weighing In
How does an object's size affect its weight? Does bigger always mean heavier?
Have students explore various objects and come to a conclusion.(*)
How much is one pound? Fill your bag with beans until you think it weighs one pound. Check your bag on a scale. Add to your bag or take beans out until you have as close to one pound as possible. Name something else that weighs one pound.
