This video summarizes an experiment performed to determine the mass of a sample of copper wire that could not be read using a decigram electronic balance. A data set is collected using longer pieces of wire that can be analyzed using linear regression. The trendline equation can be used to calculate the mass of the wire.

![Density of Water [AP Bio Lab 1.1]
Hey bio friends! I created this tutorial video showing a lab conducted to collect data to experimentally determine the density of water. The lab also serves as an introduction to using a micropipette.
In the lab, students use micropipettes to transfer water into a test tube in 200 μL (0.200 mL) increments. The mass of the water is measured after each transfer. A graduated test tube is also created in the lab that can be used for later experiments to quantify amounts of gas produced in biological reactions.
Here is a link to the video which shows how the data collected in this experiment can be analyzed in Google Sheets using linear regression.

Density is one of the important emergent properties of water covered in Unit 1.1 of the AP Biology Course & Exam Description (CED).
