In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

In this activity, learners explore clouds and how they form.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this environmental activity (page 6 of the PDF), learners identify household products that are recyclable and explore the different types of recyclable plastics.

In this activity, learners build small animated toys that move.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

Este Web site contiene links a 12 calendarios (12 meses). Cada mes contiene actividades sobre matemáticas.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this Cyberchase activity, use grid coordinates to share secret pictures with a friend. Color squares of a grid to make a picture (like a smiley face) that you keep hidden from the other person.
