Lesson Plan Title: Jack-o-liters (science lesson on metric volume)

Purpose: To construct a jack-o-liter

Materials: orange, black, yellow and green construction paper, tape, glue, scissors.

Introduction:

A cube that is 10 cm on each side is a liter. The volume of a cube is found by the equation V = l x w x h. If a cube is 10 cm on each side, the volume of the cube = 10 cm x 10 cm x 10 cm. This is equal to 1000 centimeters cubed. A centimeter cubed is equal to one milliliter and 1000 centimeters cubed is equal to one liter. Therefore, 1000 centimeters cubed is one liter. A cube that is orange and 10 cm on each side with a jack-o-lantern face is a jack-o-liter!

Procedure:

1. Cut 6 orange squares 10 cm on each side.

2. Tape the squares together to make a cube.

1. Cut out a jack-o-lantern face, stem, and any other desired items.

4. Glue the face and stem to the orange liter cube.

5. Congratulations!! You have made a jack-o-liter
