How to Find and Solve PBS Science Show Crossword Puzzles
I've spent more time than I care to admit looking for downloadable versions of PBS's science-themed crosswords. They pop up occasionally on PBS.org and related educational sites, usually tied to specific episodes of shows like NOVA or SciFriday. The tricky part isn't solving them — it's tracking down working links before they get pulled or buried. The puzzles themselves are fairly standard crossword format, usually 15x15 or so, with a science vocabulary theme. Clues range from straightforward definitions to wordplay that expects you to know the difference between "potential" and "kinetic" in both physics and everyday language. I've downloaded several over the years and printed them for classroom use, though the PDFs sometimes come out blurry depending on which browser you're using. The main hub has historically been pbs.org/science/crossword or similar URLs, but PBS restructures their site regularly and links rot fast. A good backup is searching the Wayback Machine for old crossword pages, or checking educational sites that mirrored them. Teachers who use these with students often save copies locally because there is no guarantee a given puzzle will stay live next semester.
When I first started trying to use these in my own materials, I ran into a specific problem: the puzzle answer keys were either missing or hidden behind login walls on PBS's site. You could solve the crossword fine, but there was no reliable way to check your work without creating an account, and even then the key wasn't always accessible. My workaround was to download the puzzle grid as a PDF and then manually verify answers against the episode transcripts or NASA's educational resources, which tend to have plain-language glossaries that map directly to the vocabulary used in the clues. It took longer than I'd like to admit, but it works consistently. Here is something most people overlook about these puzzles. The clue quality varies significantly depending on which season or episode they are tied to. Earlier NOVA crosswords tend to be tighter and more accurate in their scientific terminology. Later ones sometimes get sloppy, mixing up similar concepts or using outdated definitions — I once saw a clue referencing the "nine planets" model without any note about Pluto's reclassification, which caused real confusion for students who had been taught the current model. Always double-check obscure clues against a current textbook or reputable source like the National Science Teaching Association. Another counter-intuitive detail: these puzzles are not always created in-house by PBS. Sometimes they are licensed from third-party educational puzzle makers, which is why the difficulty level can jump unexpectedly between two puzzles listed on the same page. If you encounter one that feels unusually hard or easy compared to the others, that is probably why. Checking the puzzle credits at the bottom of the page — if they are listed at all — will often tell you who made it.
For downloading, the best approach is right-clicking the puzzle grid image and saving it as PNG or PDF, then printing it yourself rather than relying on any built-in print function, which often crops the grid awkwardly. I've found that using Firefox instead of Chrome preserves the layout better on these particular pages, though that is a minor detail that matters more when you are printing thirty copies for a classroom than it does for casual use. If you are looking for a direct link to the current active version, it changes frequently enough that I would rather point you toward the PBS Science Crossword search page and suggest doing a site-specific search rather than relying on a URL that may be dead by the time you read this. The general search pattern that works reliably is pbs.org crossword science NOVA in any search engine. That will surface whatever is currently indexed. One honest limitation worth stating plainly: these puzzles are not as comprehensive as standalone science vocabulary programs. They cover a finite set of terms per episode, and unless you are solving a large volume of them across many episodes, you will not build broad scientific literacy from them alone. They work best as supplemental material — a warm-up activity or a review tool after watching the associated show. Using them as a primary teaching resource will leave gaps in coverage that are easy to notice if you compare the clue vocabulary against a standard middle school science curriculum.

For a more complete alternative, some educators prefer the puzzle libraries at NASA's education portal or the American Museum of Natural History's website. Those sources maintain their archives better and provide answer keys more consistently, even if the presentation is less polished. PBS crosswords are fine for what they are, but they are not the deepest resource available, and treating them as such will lead to frustration on either end.
