[2015] Zach Wenzel: The Effect of Metal on Heat Conductivity

The Effect of Metal on Heat Conductivity

Hypothesis

If the black iron steel is heated up, then it will conduct heat the best because it is dark.

Purpose

The purpose of this experiment is to find out which metal conducts heat the best.

The manipulated variable is the type of metal. My control was the indoor temp. My level 1 was the Sun temp. My level 2 was the blow torch temp.

Manipulated Variable

Responding Variable

The responding variable is the heat the metal conducts.

Constants

The constants are the blowtorch and the Sun.

Materials

My materials are:1. Blowtorch2. Aluminum3. Copper4. Black Iron Steel5. Galvanized Steel6. Braided Stainless Steel7. Brass

Procedure

1. Gather materials2. Record regular data/temp.3. Put the aluminum piece in the sun4. Record data/temp.5. Place piece in shade6. Record data/temp.7. Blowtorch the piece8. Record data/temp.9. Repeat 2,3,4,5,6,7&8 with all metals

The brass held the heat from the sun the best because it was thick and it took a while for the heat to leave it. The braided stainless steel held in the heat from the blow torch the best because it was very thin, so it heated up fast. So, in the end, my hypothesis was incorrect. I believed that the black iron steel would hold the heat the best because it was dark, but I learned it would take a lot longer.

My results stated that the brass heated up the most in the Sun, and the braided stainless steel was heated up the most by the blow torch
