I’ve been planning to use toothpicks and marshmallows to build SOMETHING- and now we have a book to use an amplifying activity…I am in LOVE with the bridge book and concept. We will be doing that activity in the future for sure….
I love building activities sparked by books. Building is my favorite kind of creativity, I think because it all goes back to my days of Lego building as a kid! The variation in this post is awesome!
What an amazing camp! I would have loved to have been in your class.
Thank you for linking to Read.Explore.Learn. I am pinning this post.
Thanks for pinning, JDaniel4’s Mom!!
I love all of these! So creative and so clever. How fun.
Thanks Jen!
Can I just say awesome?! You did most of the work for us. I love connecting books with projects. My son’s two favorite things. My son’s a little old for some of these things, but we can certainly work on them together or have friends over to create together. I would LOVE to see more of the same. Thanks!
Your note made my day, Karla! Thank you. 🙂
This is incredible! Am pinning and reposting now!
You’re the best! Thanks Boy Mama Teacher Mama.
Found you from “I Can Teach My Child”. I love these ideas and the creativity it sparked. I’m going to pin this to use next summer, when I try to do activities and fun stuff with my own children. Thanks so much!
Great ideas. I love when the children create their own challenges. We will have to try your bridge penny challenge.
Thank you, Margaret! Let me know if you give the bridge challenge a try. 🙂
I love everything about this post! We have some tin can robots just like that too – we used magnetic letters to give them names too!
These are amazing! How you need for each lesson? Do you think an hour is long enough for the read aloud and activity?
Thanks for your kind note, Jess! Yes, it took us about an hour to complete the read aloud and activity.
I love the tips, that’s so helpful for me in my daily life
What a wonderful list! So glad you shared. Thanks for promoting STEM to kids! 🙂
I am new to homeschooling and the STEM activities you shared will be great to use with my girls! Thank you for sharing.
This is great stuff…I live in the UAE and was exploring for new ideas…thanks for sharing!

help me I don’t know haw to do it so help
this is not 40 in all of the categories just sayin
You have wonderful ideas here that can keep children of all ages busy for hours. The pictures are vibrant.
Suggestion: As a teacher, it is really difficult to read your site. Pale blue on white really strains the eyes.
I am very much interested in implementing STEM studies into my home school. Grade k – 8th . Please help me understand what is the best way to start with your products. Thank You
Awesome & brilliant idea it`s very helfful of child education.
“Create straw roller coasters. // Frugal Fun for Boys”
First thing I want to say is that I love the fact that websites like this exist but…
I’m a civil engineer. I design the structural systems for buildings and bridges. I was looking for a project to do at a transportation summer camp when I came across this project. I am ultimately disappointed in you because you target roller coasters for boys. Really? Please correct as it is hard enough as a girl to be told that you can’t play with Erector sets or Legos because they are for boys as well…
Thanks
Hi Kelsey,
Thanks for reaching out. We couldn’t agree more that Erector sets and LEGOS are just as much for girls as they are for boys. The site that published the article is run by a mom of four boys (and one baby girl). When she started her blog “Frugal Fun for Boys” many years ago, she intended to share all of the cool, low cost projects her four boys designed together. The blog title has nothing to do with “boy only activities” and everything to do with the gender of her kids. In fact, since welcoming her daughter, she updated her blog logo to say “Frugal Fun for Boys AND Girls”. Hope that helps clarify!
Warmly,
Kimberleigh
It would be nice to have a PDF of all of these activities so that we’re not searching the website, and we can just print it out.
Hi Laura,
Thanks for reaching out. While I understand that a PDF would be convenient, this list is a collection of STEM activities from a variety of authors, so we can’t create a PDF.
If you’re looking for a PDF style version of STEM activities, you might be interested in our ENDLESS STEM Challenge Bundle.
Let me know if I can be of any further help.
Warmly,

Hi Malia,
I recently purchased your endless STEM bundle and was wondering if there is a comprehensive materials list or some sort of materials list for each activity. Or do I need to download each file to see what I need to purchase?
Thanks so much for sharing your amazing activities!
Beth
Hi Beth,
