Read the scenario and determine if work happened. Taryn pushed against the brick wall and the brick wall did not move.

• Taryn did do work because she used her energy against the wall.

• Taryn did not do work because the wall did not move.

• Taryn did not do work because the wall did not use energy.

• Taryn did do work because the wall is using Taryn's energy.

Read the following experiment: Alex wanted to figure out if the material of plant pots affect how plants grow. He grew four tomato plants and watered them everday at the same time. Plant 1 grew in a plastic pot, Plant 2 grew in a glass pot, Plant 3 grew in a stone pot, and Plant 4 grew in a wood pot.

What was the independent variable? (What was changed on purpose?)

• The type of tomato plants

• The amount of water given to the plants

• The time of watering the plants

• The material of the plant pots

What is taking place in this picture?

• Eletrical and Mechanical energy are being created

• Electrical energy is being transformed into mechanical and sound energy.

• Electrical, Mechanical, and Sound energy are being created by the blender.

• The fruit's energy is being destroyed.

Which of the following demonstrates the Law of Conservation?

• A piano player is playing on the piano and sound is produced.

• A football player throws the football across the field.
