Measuring Using a Scale and Graduated Cylinder

In the past days, we've completed one lab. In this lab, we had to measure certain objects using a scale and graduated cylinder. One column was for our guesses on how much it weighed. The other was for actual measures. We then used the formula: predict-measured/measured x 100% to find out the percent difference of what we guessed and the actual. To find out its weight, we put the object on the scale and moved the ten marker and hundred marker until it is balanced. For the objects using water, we measured the volume by pouring the water into graduated cylinders.

Penny Lab

In this lab we turned a copper penny into gold. We achieved this by soaking the penny into a bowl of sodium hydroxide. While soaking, the penny changed into a silver shade. If the sodium hydroxide gets on skin or eyes, it burns. I believe this also applies to the penny. Burning the copper color, the sodium hydroxide cleans it leaving a smooth, silver slate. After this process was completed, we used tongs to burn the penny over a bunsen burner. Like when something burns, it turns yellowish-tan. This concept was shown in the change of color in the penny. In conclusion, our penny was gold.
