Module 1:Accuracy and Precision Lab and Density Labs

What is due this week?

1. Do the Accuracy and Precision lab.
2. The Density lab uses the objects. Make a data table for this lab.
3. Bowling for Density is a calculation.
4. Take a photo or short video of the completed Cartesian diver lab.
5. These labs are this week’s work.

Accuracy and Precision Lab

1. Drop a wet sponge into a cup.
2. Measure distances outside the cup
3. Count a direct strike into the cup as zero.
4. Answer all of the questions.

Accuracy and Precision Lab

What is density?

1. Density is mass/volume
2. The units are usually in g/mL or g/cm3
3. 1 mL = 1 cm3

It’s All About Density!

1. There are two methods to determine volume: direct measurement or volume by displacement.
2. Some objects can be measured both ways. Others are irregular.
3. Measure the density of water. Weigh the cylinder. Add 20-50 mL of water. Weigh the water. Don’t forget to subtract the mass of the cylinder.
4. Create a data table to submit.
