Pros: Kids see a reason to learn major science concepts because they're solving relatively realistic problems.

Cons: Some investigations could be more tightly linked to the problems presented in the initial video.

Bottom Line: An engaging way to weave some engineering into your middle school science lessons.

Middle school teachers who are looking for ways to meet the engineering standards in the Next Generation Science Standards (NGSS) will love Mosa Mack Science. Be sure to use Mosa Mack's units in a way that keeps the science content central to solving the problem at hand. This way you can help kids to see science as necessary and useful. When letting kids design their own investigations, start by placing all the materials they might want to use at a central location. It's important to give kids time to puzzle over their problem, look over the materials, and make a plan. Allow your students to share out plans with the class and build on each other's ideas.

Mosa Mack Science features earth, physical, and life science units aimed at middle school classrooms; each unit emphasizes the NGSS Science and Engineering Practices. Students start by watching a cartoon featuring the likable character Mosa Mack, Science Detective, a young woman who solves science problems. Teachers can organize each unit around a host of provided materials: lesson plans, graphic organizers, quizzes, slideshow presentations, videos, and rubrics.

The videos here are used to introduce a problem, like the Mystery of the Ailing Fern, as well as the high-yield vocabulary necessary to create a solution. The program's Lesson 2: The Make is a hands-on investigation where students might find themselves at stations, exploring the different states of matter. Lesson 3: The Engineer closes each unit with a design challenge where students can use the content they've learned so far.  

Mosa Mack Science places scientific phenomena first in its units. Like Mystery Science and other NGSS science programs, Mosa Mack engages kids with a scientific puzzle to solve. In the second lesson (The Make), teachers have access to plans with leveled differentiation options. Level 1 is simply a teacher demo, while level 4 has students completely design and conduct an investigation themselves, addressing the NGSS Science and Engineering Practices. A few of the inquiry investigations could seem a little bit unnecessary. For example, creating a model to see the effect that trapped heat has on temperature; most middle school kids will get -- without the investigation -- that this makes it warmer. In Mosa Mack's third lesson (The Engineer), kids solve engaging design challenges. In one scenario, students help a pet store owner who has run out of oxygen pumps -- they'll learn about photosynthesis before engineering a solution using the water plant Elodea. Sample solutions and detailed descriptions of needed materials support teachers throughout.

The unit and lesson plans are well-thought-out, with plenty of teacher resources. Tools provided move beyond the traditional worksheet, including digital drag-and-drop vocabulary maps. Teachers can create tests from question banks dominated by multiple-choice vocabulary questions. They can also add their own questions to the test. In an effort to mirror NGSS assessments, Mosa Mack includes some advanced options such as adding images to questions, checkbox selection, and open-ended responses. Mosa Mack is missing some of the interactive item types offered by tools like Concord Consortium, such as dragging data points to build a graph.

Overall Rating


Kids stay engaged because they're at the center of this type of learning. The funny, short cartoons naturally hook students into solving the problems.


The program helps teachers address all three dimensions of the NGSS. Kids get content centered on core ideas and a chance to investigate and engineer solutions.


Videos have subtitles in English and Spanish. Teachers have access to answer keys, as well as detailed lesson plans that include options for differentiation.

Mosa Mack Science is the Trifecta of Blended Learning Tools - Students Solve Content Based Mysteries, Conduct Hands on Lab Activities and Engineer Solutions.
This is one of the most detailed and useful content based tools that I have reviewed but it is only free to try and not all units are available to use with the free version. I do love how it includes everything I need to use for the lessons immediately. After reviewing the materials I have all of the instructions and student directions to use in my classroom. I love that the content is presented as a comic, making harder concepts less intimidating to students. I also think the hands on activities a ...
