In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

In this activity, learners of all ages will roll a ball coated with paint to artistically visualize the motion of the object.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners make a photographic image—without a camera!

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners make a Benham Top to explore visual illusions and optics.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta, explorando el salón, y usando su creatividad.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.
