In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

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.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

This is an online Flash game where learners can experiment with ballistics and how to compensate for the varying levels of gravity found on the planets of our Solar System.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this activity, learners build water-propelled engines from soft drink cans.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
