Design an experiment to test how the length of a wire affects its resistance.

• Measure the resistance at different temperatures using the same length of wire

• Use wires of different materials but the same length and measure resistance

• Cut a wire into different lengths and measure the resistance of each piece

• Keep the wire at the same length and change the voltage across it

DOK Level 3: Strategic Thinking

Explain why cells are often called the "building blocks of life."

• Because they can exist independently of other cells

• Because all organisms are made up of cells

• Because cells contribute to the organism's genetic material

• Because cells are capable of performing all functions necessary for life
