How to fill out the Unit 1: Measuring The Earth - 2 Lab Hours online
This guide provides clear instructions on how to complete the Unit 1: Measuring The Earth - 2 Lab Hours form. Each section is outlined to help users accurately fill out the required information and complete the lab tasks effectively.
Follow the steps to accurately fill out the form online.
- Click ‘Get Form’ button to obtain the form and open it in the editor.
- Enter your name in the designated field labeled 'Name.' This should include your full legal name.
- Input the current date in the 'Date' field, using the format MM/DD/YYYY.
- Fill in the 'Period' section with your class period or time slot for the lab.
- In the 'Data Table A' section, follow the procedure to measure the mass of the graduated cylinder first, and enter the mass in the appropriate box.
- Measure 2 ml of alcohol using a pipette and record the mass of the graduated cylinder plus alcohol. Subtract the mass of the graduated cylinder to find the mass of the alcohol and record it.
- Use the formula for density (Density = Mass/Volume) to calculate the density of the alcohol, and record it in 'Data Table A.' Repeat this process for all samples of alcohol as specified.
- In 'Data Table B,' weigh each sample of aluminum and record their masses. Measure the volume for each sample and calculate the density, entering the data in the respective boxes.
- Construct line graphs for both the alcohol and aluminum samples based on the calculated density data and label each line appropriately.
- In the 'Analyzing the Graph' section, answer the questions based on your graph and recorded data, providing complete and clear sentences.
- Lastly, complete the discussion questions and the conclusion section, making sure to articulate your understanding of the concepts covered in the lab.
- Once you have filled in all required sections, save your changes, and utilize the options to download, print, or share the document as needed.

'Centrifugal force' due to the spinning lowers your body weight by about 0.4 per cent at the equator relative to its weight at the poles. The Earth's spin also causes the planet to bulge, so that at the equator you're about 21km further from the Earth's centre of gravity and so weigh around 0.1 per cent less.
