Engineering

Engineering activities for 4 year olds.

Engineering for a 4 year old is build, test, change one thing, and test again. These ideas use simple materials and avoid projects that depend on perfect cutting or adult-only construction.

Quick pick: After the first try, ask for one redesign: wider, taller, stronger, flatter, or slower.

How to choose safely

Match the activity to the child in front of you, not just the age label. Use larger pieces when younger siblings are nearby, keep ramps and towers low, and supervise tape, pom poms, small blocks, water, rubber bands, or anything that can go in a mouth.
