Books and articles are what you'll cite the most, so really learn how to cite those properly. For everything else, Google is my go-to. For example, if you're not sure how to cite a video in-text, just Google "video apa in-text". Look for results from apastyle.org, and college libraries or writing centers.

Don't try to do this in Google Slides - just do it in Word or Google Docs, and copy/paste it into Google Slides.
