CHEM 1100-General Chemistry II Podcasts

Since there is some course material overlap between CHEM 1090 and CHEM 1100, some podcasts will work for both courses. If you are viewing a podcast and you see “CHEM 1090" or “General Chemistry I" in the title, don’t panic! I’m using it for both courses.

Apps for Scanning Dcouments

How to take pictures of one or more pages and then turn them into a single pdf file. All of these choices have free versions.

Genius Scan (7m40s, 4/11/2020)

Comes in Android and iOS versions. Easy to use and allows you to compress your exported pdf file. My favorite option out of these five. Evaluated on an iPad Pro running iPadOS 13.3.1.

CamScanner (7m27s, 4/15/2020)

Comes in Android and iOS versions. Allows you to set the scan resolution which can help with file size. In the Apple App Store it may look there's only a free 3-day trial until it turns into a paid subscription, but that's for the premium version. The free version works fine. Evaluated on an iPad Pro running iPadOS 13.3.1.

Adobe Scan (5m40s, 4/16/2020)

Comes in Android and iOS versions. You have to register to use it. Has a whiteboard option. Clean and easy-to-use interface. Evaluated on an iPad Pro running iPadOS 13.3.1.

It was available starting with iOS 11 but the procedure is probably a little different for iOS 11 and 12. Evaluated on an iPad Pro running iPadOS 13.3.1.

Office Lens (7m28s, 4/10/2020)

Comes in Android and iOS versions. It connects with your Office 365 apps and also has a whiteboard scan mode. Evaluated on an iPad 7 running iPadOS 13.3.1.

Evernote Scannable (6m35s, 4/9/2020)

Only has an iOS version. It connects with Evernote which is nice and it cleans up scans nicely. But, there's some hurry-up-and-wait and the app's control over the camera light is flakey. Evaluated on an iPad Pro running iPadOS 13.3.1.
