This packet of logic puzzles has eight different topics: 2nd Law of Motion, Average Speed, Volume, Density, Momentum, Work, Power, and Atomic Structure. There are nine puzzles in all because there are two versions of the average speed puzzle: one that requires unit conversion and one that does not.
Note: For a limited time, I am offering a "Six Weeks to Summer Survival Kit" that includes this bundle, my Jeopardy Games Bundle, AND my Task Card Bundle. It's an amazing value at $29.99 and not only will help your students review and stay engaged in the weeks before summer, it will be a great toolkit for you for years to come! Find it here: Six Weeks to Summer Survival Kit
I love using logic puzzles with my students as transition activities, as bell-ringers, and even as part of my emergency sub plans. They are also great for enrichment - kids enjoy the challenge!
Each of these puzzles is available separately at my store, but they are $1.29 each, so you get a great value when you buy the bundle. These puzzles are most appropriate for a physical science or general science class - I have used them successfully with 7th - 10th grade students and I imagine they would be fine with 6th grade students who are familiar with the formula/math of the topic, with support.
I have many other high-quality products here on TPT - here are some links to some of my best-sellers:
