When I started teaching STEM science using PBL, I found out that, although there are millions of resources for "dessert projects" for middle school, there was not much in terms of the invitations to learn that I was looking for at this level. I started modifying or adapting what I found, and came up with several entry documents that I am now using in my practice. All of these have a "teacher corner" where you will find enduring understandings, essential questions and NGSS and CCSS alignment. All of them are intended for middle school, but they could easily be used across grade levels depending on the need to knows of your students. Hope you find them useful.

If you are ready to branch out on your own, I invite you to read my PBL toolkit post.

If you would like to have these resources sorted by NGSS standard, visit my LiveBinder.

  1. WOW, I'm am so impressed by the quality of your sites and projects! Thank you SO much for sharing and spurring ideas for my middle school classroom! Keep up the great work!

  2. Mariana,

    Thank you so much for creating this resource. I've encountered the same problem you mentioned (all sorts of "projects", but no real in-depth scientific research projects). I was curious how you introduced these? Do you simply allow students to learn through their research? Or do you teach general lessons first and then allow them to specialize and deepen their understanding?

    Thank you again for this, I believe you just saved me 2 months of coming up with bad ideas!

    1. It really all depends on the students I have and the support they need. I usually start with a class know-need to know chart, which gives me an idea of which students will need a more direct approach, and which are ready for a individual/group research. I hold mini-workshops where I provide explicit instruction on the identified areas of need (some students are invited, while others may join if they feel they need it).

  3. Hi,
    My biggest roadblock in developing a good PBL is how to make it engaging, relevant, and real-world to the kids so that they will be engaged and it won't just become "another project". Any good resources, advice or anything else to help me figure out how to create authentic PBL products?

  4. The Buck Institute and High Tech High are good resources. Also, the Edmodo PBL community has been quite helpful. When I first started, I was developing webquests. After a while, and lots of reading, I started transforming the webquests into project-like scenarios. Once you have a feel for what you need in a project, you kind of start seeing project possibilities around you. For example, I am in CA, and between this year's drought and the fact that the water district is re-furbishing some of the percolation ponds around us, I started thinking of how I could use that for a project that my students would find both timely and relevant; talked to the water district, invited some speakers and viola, the water conservation project is born.

  5. WOW I love this. Thank you so much for creating. I have always been into PBL but didn't know where to start.
