+## Learning Objectives
+
+In this lab, you will practice...
+* Loading data in json files
+* Loading data in csv files
+* Using try/except to handle malformed data
+

+
+## Note on Academic Misconduct
+
+You may do these lab exercises only with your project partner; you are not allowed to start 
+working on lab-p10 with one person, then do the project with a different partner. Now may be a 
+good time to review [our course policies](https://cs220.cs.wisc.edu/s23/syllabus.html).
+
+**Important:** p10 and p11 are two parts of the same data analysis.
+You **cannot** switch project partners between these two projects.
+If you partner up with someone for p10, you have to sustain that partnership until end of p11.
+**You must acknowledge that you have read this to your lab TA**.

+
+## Segment 1: Setup
+
+Create a `lab-p10` directory and download the following files into the `lab-p10` directory.
+
+* `small_data.zip`
+* `practice.ipynb`
+* `practice_test.py`
+
+After downloading data.zip, make sure to extract it (using [Mac directions](http://osxdaily.com/2017/11/05/how-open-zip-file-mac/) or [Windows directions](https://support.microsoft.com/en-us/help/4028088/windows-zip-and-unzip-files)). After extracting, you should see a folder called `small_data`, which has the following files in it:
+
+* mapping_1.json
+* mapping_2.json
+* mapping_3.json
+* stars_1.csv
+* stars_2.csv
+* stars_3.csv
+* planets_1.csv
+* planets_2.csv
+* planets_3.csv
+
+You may delete `small_data.zip` after extracting these files from it.
+
+
+## Segment 2: 
+For the remaining segments, detailed instructions are provided in `practice.ipynb`. From the terminal, open a `jupyter notebook` session, open your `practice.ipynb`, and follow the instructions in `practice.ipynb`.
+
+## Project 10
+
+You can now get started with [p10](https://git.doit.wisc.edu/cdis/cs/courses/cs220/cs220-s23-projects/-/tree/main/p10). **You may copy/paste any code created here in project p10**. Have fun!
