Here’s a simple open-ended building activity for kids of all ages – Colored craft sticks, wooden cubes, and small plastic cups! Simple materials, and yet we have been having a blast building all kinds of amazing structures with them.

Four Engineering Challenges for Kids - With Craft Sticks, Cups, and Cubes

This project is the second project in our Summer STEAM Camp series! This week, we are exploring with the sense of touch.

Here are the materials we used for this project: (Amazon affiliate links)

Who knew that craft sticks, cubes, and cups could be so interesting? Extend the play and learning with these fun engineering challenges.

Challenge #1: Build a structure with one cube as the base. Yes, just one cube!

When I announced this one, the boys told me it would be impossible. So I showed them this construction which I had already built:

So then Owen came up with this:

And Gresham built this:

As long as you add pieces on both sides of your structure simultaneously, you can build some amazing designs!

Challenge #2: Using any size base, build the tallest possible structure.

Stacking craft sticks on top of plastic cups allows you to build a much more vertical structure than what you can make with cups alone.

Challenge #3: Feats of Balance. Make something stick out in an impressive way!

This structure that Aidan built seemed to defy gravity! Those cubes are really lightweight, and it was hard to believe that they could counterbalance the craft sticks and cups sticking out like that. But add enough of them…

How many cups can it hold?

Challenge #4: What can you build with just one cup as the base?

More than you might think!

Bonus Challenge: Build a chain reaction!

Remove the first cup, and the sticks fall down in a chain! See how to make it here: Simple Popsicle Stick Chain Reactions

    This looks amazingly fun. :) Pinned and will probably use this as a Sunday School activity!

      Really great resources! Good for parents and schools. It is a huge way to engage learners that are Kinesthetic and help balance childhood education. the materials are cost and nature friendly. Thank you so much for sharing.

          Thanks so much for sharing this activity. Just had one quick question. How many sticks, cups and cubes did you use to build the tallest possible structure (challenge #2). Appreciate your help. Thanks in advance.

            I am the STEM teacher for a Pre-K - 5th grade school. I love your activities. I want to do this one, but will need to make sets so that I can easily pass them out. How many sticks/cubes/cups did you make for each set?

            Thanks for all your great ideas!!

            Sarah! I love this engineering challenge! What a great way to keep the kiddos entertained and thinking this summer! We'll definitely try this one! Tracy

              I simply love love love these challenges!!! I think they will definitely keep kids engaged and learning. I do have a few questions; however, since I'm teaching a STEM program for rising 8th grades this summer. What was the biggest takeaway(s) you were trying to get your kids to learn in these challenges? Did you have them work in groups? How long did they have for each challenge? How did you divide the responsibilities between each person? Sorry for all the questions, and thank you in advance for your response. Keep up the great work. Also if there's a website you can direct me to that will answer some of these questions that would be great as well. Thanks again.

                Well, our set up was pretty informal. It was just my 11, 8, and 6 year old's building, so they each did their own thing. No groups and no division of responsibility, etc. Since my kids are younger than the ones that you are teaching, my goals were just to explore balance (adding equal weight to both sides of the structure, etc.), to explore design - creating patterns with colors and just exploring interesting designs, and to build coordination.

                  Silly question, but where did you get those cubes? Those could be handy for many activities. Thanks.

                    We got them at Hobby Lobby, but I saw them the other day at Michael's too. Any good craft store should have them! They really are quite useful!

                      I've seen them at the dollar store by my house, as well as lots of sizes of popsicle sticks. So make sure to check that out too and could save a few $$!

                        How many bags of the blocks did you use? Unfortunately, the store I went to the other day only had 1 bag. I definitely want more but wasn't sure how many bags is ideal. This looks like so much fun - I can't wait to try it myself! Thanks for sharing.

                        I would only add that another source for the wooden cubes is Craftparts.com - a great resource for wooden objects of all sorts of shapes and sizes!

                        Here is a link for 1" wooden cubes - http://www.craftparts.com/square-block-cubes-p-2628.html

                        Oh my gosh! Love these ideas. I don't have kids yet, but do tons of babysitting. These challenges would be great with the kids!

                          Fun ideas!

                          I have a daughter named Gresham and I was surprised to see you have a Gresham too! What is your Gresham's namesake? We got the idea from Joy Gresham, who married C. S. Lewis.

                            That's great! We got the idea from the same place. Well, from Douglas Gresham (her son). Also, I had heard someone calling their son "Gresham" in Toys R Us and liked the name!

                            I can't wait for the day that my boys WANT to build things! (I've got toddlers) These are great ideas; I'm so glad you shared!

                              Wow! I work at a library and we just finished completing these challenges for an Evil Genius Club program. The kids LOVED it! They were totally engaged. You could almost see the wheels turning inside their heads trying to figure out what to place where. Thanks for the awesome idea! I'll definitely be checking out more of your site!

                                Hi, I love these ideas and have bought the components but wanted to print out and laminate the challenges. I've tried all sorts of things including copying all the text and pictures into word but I can't get them to print in any way that doesn't mean the pictures are over several pages. Is there any way you can come up with a print friendly version please? Thank you

                                  Thanks for sharing this activity.. I have dominoes and jenga blocks do you think they can work instead of the cubes.

                                      The video playing is very distracting. Why isn't there an option to close it?? I like this website , but that;s enough for me to leave this site and find similar information elsewhere.
