Question about Citing in Part 2E of Explore PT

My students are using the actual innovation’s product website as a source. Often, there is no publishing date on these pages. How do I advise them? Yes, I know this is super last minute.

I’ve been telling them that 2 out of 3 sources need to be newer than the end of the school year, so they can use the product website as an additional source to exceed the minimum.

I would check the product website’s PR, News and or about pages for information on the innovation. If there is a blog linked to the site, there could be dated information there.
