Simple and Fun Lessons on Engineering for Elementary Students

Today we are beginning some hands-on lessons to introduce T to engineering. We are starting slow with this very simple marshmallow/toothpick tower and will move into more difficult problem solving with more advanced goals but you have to start somewhere.

Lesson Goals

  • Recognizing shape strengths
  • Problem-solving with only the items assigned
  • Have a lot of fun and build a super cool marshmallow tower

Vocabulary for this lesson.

This is new so first things first. Let’s see how the Bing Dictionary defines Engineering for us:

  • application of science to designing things: the application of science in the design, planning, construction, and maintenance of buildings, machines, and other manufactured things
  • profession involving technical designing: a branch of engineering pursued as a profession, e.g. civil engineering or electronic engineering
  • contrivance: the planning or bringing about of something, especially when done with ingenuity or secretiveness

Impressive Engineering Examples To Discuss

We are also going to look over this list of: Top 10 Most Impressive Engineering Projects from Engineering Daily. Here we will see that engineers are behind totally cool and awe-inspiring things such as the Moon Landing, The Hoover Dam, The Pyramids of Giza and more.

Watch A Video

Finally, T is a huge Guinness Book of World Records Fan so we are going to watch this YouTube Video of World Record Engineering Marvels and get oh so inspired!

Time To Learn About The Strengths of Shapes

To cover shape strength, we discuss which shapes we assume are the strongest and then we watch this video.

See How It’s Done

Then we are going to watch this to see how it has been done before with this Time-Lapse Video.

Time To Build Our Marshmallow Tower

And now we are ready. Let’s see what he can do!

Items you need for this Marshmallow Tower Project:

  • Mini Marshmallows
  • Toothpicks
  • A base of some form to build on so that you can turn it easily.


Step 1 – Build a base.   T didn’t skimp on the marshmallows!

Step 2 – Build upwards. Try for 5 inches of stable height.

Step 3 – Reach for the stars! See how high you can build it! 

Step 4 – Record your results and include notes on the experience. What worked and what didn’t. What did you learn?
