Sure, I can help you with that! Here are the steps to find a bell curve graph template in Microsoft Excel:

1. Open Microsoft Excel and click on the File tab in the top left corner.
2. Select New from the menu on the left-hand side.
3. In the search bar at the top of the page, type "bell curve" and hit enter.
4. You should see a variety of templates for bell curve graphs. Choose the one that best fits your needs by clicking on it.
5. Once you've selected a template, it will open in a new Excel workbook. You can then customize the graph by adding your own data and adjusting the formatting as needed.

If you don't see any bell curve templates in the search results, you can also try searching for "normal distribution" or "Gaussian distribution" templates, as these are other names for the bell curve. Good luck with your project!
