Detailed Examples for K-12 Teachers

Putting together a PBL science plan can be enormously time consuming without excellent models. So here are hundreds of free detailed plans for projects for elementary, middle and high school students. The plans are sorted by discipline - astronomy and space, chemistry, engineering and architecture, physics, technology, and earth, life sciences, physical sciences, and... well, "other" for no clear fit. Most of the ones I've listed provide project overviews, guiding questions, procedures and activities, work product descriptions, grading rubrics, and questions for reflection.

The first PBL project I planned many years ago was the creation of a butterfly habitat in the school garden by my 3rd graders. I think the planning took more time than the project, and I didn't have a lot of resources to help guide me. Since then, I've been an avid collector of PBL plans.

I found far more free PBL resources than I ever anticipated, and hundreds of free science-based PBL projects are listed below. Many of these projects would also be considered problem based learning projects.

Heads up!

Astronomy & Space Science PBL

Astronomy & Space Science PBL

Astronomy and Space Sciences Projects

  • K-12 Projects | NASA
    Several projects, competitions and activities for students at all grade levels. Although not as detailed as many of the PBL projects listed here, the range available include designing, building and conducting experiments in space sciences.
  • Project Spectra! | U. of Colorado Boulder
    For students in grades 6-12. In this NASA-approved projects, students learn about how light is used to explore our solar system. It culminates with their construction of a spectrometer to interpret actual data.
  • NASA - Solar Energy for Space Exploration
    For students in grades 6-12. Students propose and defend a design for a solar power system that will support 6 explorers on the moon or Mars. Leading up to that, they develop a solar power system for a home and the ISS.

Life Sciences Projects - Projects in Anatomy, Biology, Animals, Plants

  • Human Genetics Project | CIESE
    For students in grades 6-12. Students determine if the most dominant trait is the most prevalent trait by surveying phenotypic traits of classmates, compiling data, and analyzing it with data from students around the world.
  • San Diego Bay Field Guide | High Tech High
    For students in grades 9-12. Incorporating biology, environment and math, high school students study the biogeography of the bay. They create a baseline inventory at several sites, with changes over time, and use this data to produce a field guide.
  • Endangered Animals PBL Unit |
    For grades preK-K. Teacher Megan Power thoroughly documents this project, in which her children research endangered animals, create educational materials about them, decide which ones they want to help save, and raise money for the World Wildlife Fun
  • Duke School | 1st Grade My Healthy Self Project
    For 1st grade students. Children learn all the components that go into making ourselves healthy. Then they convert the classroom into a state-of-the-art wellness center for a day and conduct physicals, offer massages, aeroboics class, and counseling.
  • KKits Bacteria | PBWorks
    For 10th grade biology students. Culminating project is a 30-second public service announcement for the CDC on how to prevent the spread of infection disease, based on research on viruses and bacteria.

I've found the best management tool is to get students excited about perspective projects. l have often looked for projects by scouring the local news for vexing problems, such as water or air quality, or mold problems in our own school. If the kids play a part in selecting the project, that goes a long way for creating buy in.

Andrew Miller, an instructional coach at Shanghai American School writes an excellent blog post on the topic and I've used many of his ideas: Hope this helps. on October 05, 2016:

This is an amazing resource article. I would love to know more about your classroom management tips for PBL. How do you get the students to buy into the process without being a drill sargent?

it will be helpful for the educators.

Great work!

my 4 primary school girls have developed amazingly well since PBL was introduced


OUTFOXprevention1 on October 11, 2013:

Great lesson ideas! We can use some of the ideas for our germ lessons.

EzLoanLookUp LM on August 19, 2013:

I totally agree with this model of teaching. Great lens!
