The life cycle of the strawberry.
You know what I love even more than when an activity goes exactly as planned? When my kids take the lesson even further than I'd dreamed. That sends this deceptively educational mom over the moon! This simple engineering activity is a perfect example. I got the idea from a local STEM event eons ago, that provided kids with mostly edible building supplies and asked them to build and evaluate which shapes created the strongest, most stable structure. On the table were gumdrops, marshmallows, toothpicks, and uncooked spaghetti noodles. For our experiment, I omitted the gumdrops. Marshmallows would suffice as our "connectors." I started by asking my oldest son to build a cube with toothpicks and marshmallows. What he soon discovered was that it was wobbly, wonky, leaning, and shaky (choose whichever adjective you like best). To stabilize it, he added diagonal lengths of broken spaghetti noodles (essentially X shapes around all the sides). We checked the cube; no more wobbling! He was excited. Now the pace of building REALLY picked up. While he was busy popping marshmallows in his mouth and building his four-story tower, little brother came wandering by. "I want to do that," said my preschooler. "I want to make a triangle." This was when the questions came spilling out of my mouth. "How many sides does a triangle have? How many toothpicks will we need?" In no time flat, he was exercising his fine motor skills to make a triangle. "I want to make an E," he said next. This took a little more instruction from me but boy, oh boy, was he proud when we were done. What started as an engineering activity for my oldest son became that AND a lesson in shape and letter recognition for my youngest son. That made the nominal amount I spent on supplies for this activity WELL worth it!
