Working Through Of The Moon Worksheet Content
The Of The Moon Worksheet is a teaching resource that covers lunar phases, tides, and basic astronomy concepts for middle school science classes. It typically contains fill-in-the-blank sections, diagram labeling, and a few short-answer questions. I've used it in a few different classrooms over the years, and it does what it promises, but there are some things you should know before you start using it. You can download it directly from Teachers Pay Teachers under the creator name "Science Made Simple." The file is a PDF at around $2.50. There's also a free version on the NASA Educator portal that covers similar material but with fewer diagrams. If you're looking for the one with the phase chart included, the TPT version is the one most teachers actually use. I tried the NASA version once because I wanted to save money, but it lacked the answer key and the labeling practice section was too bare-bones for my students. Went back to the paid version within a week.
How to use it effectively
Don't just hand it out and walk away. The worksheet is designed to be done in two class periods if you're doing it right. The first period should cover the content leading into it. The second period is for completing it with some discussion after. I found that if you skip the mini-lesson beforehand, most students will struggle with the tidal force question on page two. That question assumes they already understand the relationship between gravitational pull and water movement, which they usually haven't covered yet in the unit sequence. The answer key is included in the PDF itself as the last three pages. It's thorough enough that you don't need to modify it, but I do recommend checking question 7 before giving it to students. The question asks about the difference between a synodic and sidereal month, and the answer provided uses the synodic period of 29.5 days without explaining why that number matters practically. My students kept asking follow-ups about that and I ended up having to look it up myself to explain it properly.
Common problems and what to do about them
One issue I ran into last year was with the diagram on page one where students have to label the moon phases. The image uses a static sun angle that doesn't match standard textbook representations. Some students who had seen the phases drawn differently in their main textbook got confused about which side of the moon was lit in each phase. I had to draw a quick correction on the board showing that the sun's direction is consistent regardless of how the textbook illustrates it, and that the worksheet diagram is just one valid representation. Another thing to watch for: the tidal bulge diagram assumes a two-bulge model, which is the simplified version taught in most middle school curricula, but it's worth noting that real ocean tides are more complicated due to basin geometry and Coriolis effects. If you have advanced students who ask about this, you can tell them the simplified model is what the worksheet uses, and that the real-world version gets significantly more complex. The short-answer section on page three works best if you do it as a pair-share activity rather than having students work alone. I tried independent completion once and spent the next period re-teaching half the class on why the moon doesn't rotate relative to itself in the way the question implies. The question itself isn't wrong, but the phrasing trips up students who haven't internalized the concept of synchronous rotation yet.

What the worksheet leaves out
The resource doesn't cover lunar eclipses or solar eclipses at all, even though those topics usually come right after moon phases in a standard curriculum. I've added a separate activity from the PhET simulations website to fill that gap. You could also supplement with a simple flashlight-and-ball demo in class, which takes about ten minutes and makes the eclipse concept stick better than anything on paper. There's also no coverage of the lunar maria or crater formation. If your unit includes those topics, you'll need additional materials. The worksheet is narrowly focused on phases and tides only.
Final thoughts on the resource
It's a decent tool for the price point. Not perfect, but functional. The formatting is clean and the questions are at the right difficulty level for grades six through eight. I wouldn't use it for honors or advanced students without adding supplementary material, and the diagrams could use some updating, but it gets the job done for a standard classroom setting. If you're already using a moon phase unit plan, this fits right in without much extra prep time on your end.
