Topic: Volume (of the mouth)
Second Year Level
Objective:
Students will learn to measure the volume of an irregularly shaped container.
Materials:
Water, mouths, graduated cylinders, beakers, cups, and straws.
Procedure:
Ask students who has the biggest mouth in the class. Then ask them the focus question of how can we tell for sure that that student has the biggest mouth? Introduce the unit of milliliters and tell students that they are going to measure the volume of their mouths in milliliters to find out who has the biggest mouth. Give students cups of water and have them fill their mouths with water by using a straw. When they have their mouths full, have them spit out the water into a beaker. Then teach students how to use a graduated cylinder to measure the volume of that water. Whoever has the largest volume of water after spitting it out has the biggest mouth in the class.
