Molly is planting a flower garden. She carries the flowers from the car to the garden. She then pulls each flower out of its pot. She shoves a shovel into the dirt and digs a hole. She then holds the flowers as she places each of them in a hole.

In which case is Molly doing work? Remember, works is when an object moves as a result of force (a push of a pull). There are 2 answers! TWO ANSWERS!

• When Molly carries the flowers from the car to the garden.

• When Molly pulls the flowers from their pots.

• When Molly lowers the flowers into their holes.

• When Molly digs a hole.
