100 Building Block STEM Challenge


We finished early so I wanted to find something to challenge the kids with, so I decided on giving them a 100 building block STEM challenge. The purpose of the challenge was to get them to figure out how to build a building that would not fall down.

Each one of my kids took a turn at building their own design. I tried to have them do it together but my daughter wanted to do things her way and wouldn’t compromise at all.

STEM, Block Challenge

I started by giving them a bin full of 100 blocks of different shapes and sizes and I let them construct from there.

We talked about why their building was successful and the first thing they both said was that it didn’t fall. My son said that it would be difficult to build a building that was high because the higher you go with the blocks, they have a tendency to be loose and then tip over. He would have liked to construct a high building but he just couldn’t do it.

I felt that the kids were creative. My daughter took the longest and she would take out blocks and redo it. She had a pyramid at the top going that looked really sharp at the end but then she changed her mind and started moving blocks around again.

So in their eyes, in order to succeed they figured out that they needed to build their building wider with a solid ground so they could build and stack with out it falling. They figured out which pieces to use first and what pieces to use last.

I still plan on having the kids research building structures. I want them to look for the mathematical data and the science behind higher buildings. It could make a difference on the next round of building with the blocks.

    This is such a great project! I love your daughters design. Her building is definitely solid.

    It’s funny she mentioned that you need a solid foundation. Isn’t that how most things work? You need a solid foundation?

    Thanks so much for sharing!

    She is 6 and blows my mind at things. I was surprised with how much she understood.

    This is a great project. I think I’ll be spending some time on the floor with the girls exploring some more building concepts. They already know triangles are the strongest, but I’d love to see them apply their own concepts to strength and see what their ideas are on why their structure works. Thank you!

    You are welcome Mary! It was a fun challenge. I loved how they were similar but yet different.

    Have fun doing the challenge 🙂 We are going to research it more and then redo it and see if our buildings change.

    I love when my grandchildren come over and drag out the building blocks, train tracks, or Legos. I’m always amazed at what they come up with.
