About this workbook

25x: Physical Science - MS - 5th Edition is a 371-page black-and-white middle school workbook from 3andB, with complete answer keys and teacher lecture notes. Its 25 lessons are organized into five connected units covering scientific investigation, motion and forces, energy transfers, properties of matter, atomic structure and chemical reactions, and physical science at an astronomical scale.

Each lesson combines accessible science reading with guided notes, vocabulary, reflection questions, data analysis, hypothetical situations, crosswords, word searches, and real-world application. Updated photographs, diagrams, questions, and critical-thinking opportunities support use in classrooms, homeschool programs, independent study, supplemental science, and intervention.

The course is aligned to NGSS Middle School Physical Science Standards and current Texas TEKS Science Standards for Grades 6–8. Through repeated investigation and analysis, students learn to identify patterns, interpret data, apply scientific principles, evaluate evidence, and draw supported conclusions.

A Well-Crafted, High Value Resource

The curriculum my school provided was incomplete, and the 25x resources were the perfect addition to providing a higher value of education to my students. The content is high quality and the questions are well-written. I could see how using all the resources would create a consistent education for students, but the similar format may eventually become repetitive. I do plan on holding on to these resources for years to come.

Well organized resource!

I used this to review my students before state testing! It was a great resource! I think next year I will use this to introduce my students to new topics or to reinforce my teaching.

Such a great resource!

This has been such a great resource! I'm teaching a pull-out physical science class for the first time, and this has been so helpful!

A light even for school librarians

For clarity, I am a school librarian—not a science teacher. But every school librarian worth their salt has an arsenal of Mini-Lessons ready to go so they can best serve and co-teach alongside the classroom teachers. This book is, for me, that arsenal to first amaze then get students passionate about science. Five neutron stars, no question.

Good resource

This is a nice middle school level resource to introduce students to physical sciences topics. It covers a broad range, from basics in chemistry, physics, and astronomy. Each chapter has a series of exercises like fill-in-the-blank, short answer style questions, along with a word search. There are many colorful illustrations to keep the kids somewhat engaged. It could be applicable for a wide age range (even as low as 9 yrs. and up to maybe 13 yrs. old).

Lots of resources

Great value! Many pages and activities for the price. It will help me have appropriate-level choices for my students. Thanks.

Great for Yearly Planning

I have not used this yet, but have copied my first few units. I used them to plan my entire school year. They match up with the textbook I have, which makes it even better. My students love word searches and crossword puzzles as activities. I love the guided notes to go along with the video (which I believe the kids will like). The reading article is especially nice because it fits in with reading standards. Thanks!

Solid middle school science support

This huge physical science workbook really covers the bases—articles, guided notes, vocab, puzzles, and even YouTube vids. It’s super organized and clearly built by experienced teachers, so I can see it being a boon for busy middle school classrooms or homeschools needing a full curriculum in one book. My only nitpick: is it has that polished, mass-produced vibe (think: solid content but not super inspiring). Still, for structure, variety, and NGSS alignment, it does exactly what it promises. All in all, quite a good school book.
