Google Docs and Google Slides (aka Google Presentation) has a research tool where students can get ideas to assist them in their writing - particularly non-fiction writing as part of their studies. This provides a great scaffold for those students who struggle with their writing, but also provides an in-house tool for everyone to use to gather images, videos, information, vocabulary (synonyms from the dictionary), quotes and citation references. You can also filter images and videos to meet copyright requirements.
To access the tool, click on the Tools menu and select Research. This will open a pane on the right of the screen within the Google app.
Type in your search term and then you can select what format you are looking for.
If selecting images you can also click on the small triangle arrow to filter these for ones that meet creative commons attribution.
With videos you can see the attribution below the video once embedded.
Once you have selected your image simply drag and drop it onto your slide. For videos click Insert. Your media will now load on to your Google slide. To play the video while in construction mode just double click the movie camera icon. Note that videos will still have any advertising attached.
You can also use the Dictionary to search for more interesting vocabulary such as synonyms, or use the Everything category to get information that you can use to enrich your writing as well as the vocabulary.
The Research Tool is also available through the Tools menu in Google Docs though you can only search for videos by adding "Youtube video" to your search term within the Everything category. All else works the same as for Google Slides.
