This bundle of logic puzzles has nine different topics: 2nd Law of Motion, Average Speed, Volume, Density, Momentum, Work, Power, Atomic Structure, and the Solar System. There are ten puzzles in all because there are two versions of the average speed puzzle: one that requires unit conversion and one that does not.
Note: I also offer this bundle as a part of my "Middle School Science Survival Kit" that includes this bundle, a Jeopardy Games Bundle, my Task Card Bundle, a Metric System and Dimensional Analysis bundle AND two Periodic Table Projects. It's an amazing value at $36.99 and is versatile enough to be inter-laced into your teaching for the year or made a part of emergency sub plans. It is a great toolkit for you for years to come!

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 $1.49 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.
