What if I'm having issues viewing your PDFs?

Why does the worksheet appear completely gray?

When you click on a Mystery Science worksheet, you’ll see a preview of the document on the webpage. However, sometimes browser settings can affect whether the preview is displayed. If you see a gray screen where the document preview should be, as shown below, it's possible that your browser or computer may not have an application set as the default PDF viewer.

If you're using the Chrome browser, you can set Chrome to display PDFs using the following steps:

1. On the Settings window, under Privacy and security, click the Site Settings option.

2. Scroll down the Site Settings screen to find and click Additional Content Settings, then select the PDF documents option

3. Chrome downloads a PDF when the toggle switch is set to On and displays a PDF in the browser when set to Off.

Keep in mind that if you’re using a school-owned device, your IT department may have restrictions on what settings you can change. If these settings aren’t available to you, we recommend reaching out to the IT department at your school or district for assistance with making these changes.

In many cases, even though the preview of the document is not shown on the page, you can still use the Download button at the top of the page to download a copy of the worksheet as a PDF, Google document, or Microsoft Office document.
