Explore STEM This Festive Season

Many of the following Christmas STEM activities include one or more of the different pillars of the acronym STEM. STEM stands for science, technology, engineering, and math.

Generally, a good STEM project will include a combination of these pillars and call on lots of different skills! Read more about the engineering design process below.

These Christmas STEM activities below are really quite easy and use just a few common kitchen and laundry ingredients. Don’t be intimidated! Look around your house or classroom for suitable and inexpensive supplies. Think cups, Christmas cards, straws, playdough, and more…

I am always amazed at how much we learn from creative STEM challenges. These Christmas STEM projects are perfect for budding engineers and scientists. They are also terrific frugal, screen-free ideas that will encourage imagination, free thinking, and curiosity in kids!

Set them up at home or in the classroom with kids this holiday season for some hands-on scientific fun! Great for elementary age and beyond!

Use The Engineering Design Process For Christmas STEM

This season, why not pair the engineering design process with fun holiday themes including candy canes, gumdrops, Christmas trees… you get the picture!

Engineers often follow a design process. There are many different design processes that all engineers use but each one includes the same basic steps to identify and solve problems.

An example of the process is “ask, imagine, plan, create, and improve”. This process is flexible and maybe completed in any order. Read More Here.
