Learning about Mummies? I use this project in 6th grade World History and it is ALWAYS the favorite. This project could easily fit other grade levels.
In this project- students (in groups) will make a "mummy" out of classmates! They create fake organs, tools, and optional sarcophagus (I save them after the project to decorate the classroom). Students learn while screaming "eeeew" at the brains (slime or gak), stare intently as amulets and preservatives are used, and laugh hysterically when they watch their friends get wrapped in bandages.
Spruce the project up with STEM by asking for a "digital background" (students find a picture online and you project it so it looks like a background) OR have students record their mummifying efforts and show the video to the class.
The project page includes a brief description (so you can modify in your classroom) and a rubric.
Use a textbook for the steps, or I used BBC Mummy Maker for a more detailed process.
The Comprehensive Rubric includes a "Group Work Grade".This allows students to rate each other. At the end of the project- the teacher may ask if anyone did not contribute- every teammate that complains about a student is -1 on that student's "Group Work" grade. You could also allow students a silent ballot to rate each other's contributions.
