The inspiration for this Christmas ornament STEM activity came from our diy geoboard activity. When our children were younger, we would go to the building classes at Home Depot because they loved building things and using tools.
So, this geoboard Christmas ornament STEM activity was popular with our kids. They were able to use tools, nails, and real wood to create unique ornaments for our tree and for gifts.
Geoboard Christmas Ornament STEM Activity
- Draw a horizontal line on the face of the tree cookie.
- Starting at the left end, dot the line every 1/2 inch.
- At the first dot, draw a line perpendicular to the first line, all the way down the ornament.
- Draw another horizontal line 1/2 inch below the previous line, making sure it is parallel to the line above it.
- Draw a dot where the perpendicular and second horizontal line intersect, and every half inch down the horizontal line from there.
- Continue to draw and dot lines 1/2 inch apart, all the way down the ornament.
- Add nails. Hammer a nail into the tree cookie at each dot from STEP 1. I would start the nail for my son, then my children would finish hammering it into the wood, leaving about 1/4 inch of the nail sticking out of the wood.
- With all the nails in, our natural wood geoboard ornament was complete!
- Add a design to the geoboard ornament. I pulled the yarn, and asked my son to cut it. I tied a knot to one of the nails, then asked my son to create a design around the nails.
- When my son was done with his design, I tied the yarn to one of the nails, then trimmed and tucked the yarn into the design.
Each ornament is unique and makes a fun gift for grandparents, teachers, neighbors, or nursing home residents.
