This is a perfect Thanksgiving STEM Challenge or Halloween STEM Challenge to keep your kids engaged this fall in brain-busting work disguised as fun.

The basic premise:

Individually, or in partners/groups, students will design and build a device to harvest a field of pumpkins as efficiently as possible. (Efficiency is measured in amount of time or number of moves needed to clear the pumpkin patch.) Once picked, pumpkins will be deposited in a harvest container.


Note: This is the printable version. If you are in a 1:1 / paperless classroom, you will want to check out the digital option for use with GOOGLE SLIDES (TM) instead.

Sample/suggested materials for each student or group:

(Materials you’ll need to do the activity are easily modified.)

o Candy pumpkins or candy corn (24 – 36) (Rolos or wrapped caramels can be substituted)

o Pipe cleaners (5 – 10)

o Popsicle/craft sticks (10 – 15)

o Plastic spoons (5 – 10)

o Bowl or holding container for harvested pumpkins

o Scissors

o Copies of pumpkin patch guide handout or green construction paper

o Copies of data recording & analyzing handouts

o Optional:

• Straws

• Clothespins

• String

• Rulers/measuring tapes

• Tape, cable ties, rubber bands


Benefits of this STEM Design Challenge:

- Focus on critical thinking, problem solving, and application of learning

- Helps students develop growth mindset traits like persistence and resilience

- High levels of student engagement

- The potential to hit upon all NGSS ETS standards depending on the depth and number of iterations you choose to implement in your classroom (modifications included)

- Highly flexible and differentiated for materials, timing, grade levels, and rigor.

Each design iteration should be planned for ~60 min. if you are including data gathering and analysis rather than just building for fun. If you add extension activities, you will need to adjust timing accordingly.

This particular challenge is a perfect opportunity to practice multiplying & identifying factors with arrays, measurement, perimeter & area, multiplying % to project how changes in design efficiency or pumpkin patch size might impact future results. Suggestions for these and other types of math extension problems/tasks are included.


What do teachers have to say about this resource?

“This is a fun STEM challenge that is very thought provoking. Excellent tie in to writing and math, and very detailed teacher notes and steps. That makes it so much easier to get everything set up so the students can start learning. Great product! Thank you!”

“Perfect for my little engineers!”

“I used this with my 8th grade STEM class and they had such an amazing time. I couldn't find any pumpkin candies or candy corn in stores (even though it wasn't even Thanksgiving yet) so I used caramels instead. It worked like a charm because they are about the same size and consistency. I will be using this again!”

"I was leery about paying $4 for this because it seemed like something I could easily do on my own, but there are lots of extra resources and ideas that would allow you to extend this challenge into a week or even more. Well done!"
