Curiosity Bundle · Grades 3-5

Around the House

Look closely at familiar household mechanisms and compare safe models.

Pick a question to explore together. Find readings, hands-on discoveries, and printable sheets inside.

Choose a question

Watch a zipper join and separate its teeth. Try a paper model and explore what the little slider does.

Explore a familiar flush through reading and a clean-water model, with no tank opening or repairs.

Notice what changes with each click, test a simple model, and explore the parts that keep a pen tip in place.

Compare shapes and try a fictional paper lock. Explore why a match matters without opening a real lock.
