Experience a spinning spiral...you won't be hypnotized, but you'll see what happens when you look away. It's like getting off a merry-go-round and everything keeps moving.
Find Someone: Use Math to Learn About Friends
Source Institutions
Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

Egg Drop
Source Institutions
Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

Designer Ears: Make “better” ears!
Source Institutions
Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

Tessellations
Source Institutions
In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

Crazy Shapes
Source Institutions
In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.

Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.
Starburst® Graph
Source Institutions
In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.

Pencil Balance
Source Institutions
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.
Pass or Roll!
Source Institutions
In this math activity, learners play a game in which every roll can earn you counters, but if you roll the wrong number (6), you have to put everything back.

Source Institutions
Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Magnetic Marble Run
Source Institutions
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.

Build a Bubble Circuit
Source Institutions
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

Make Ziff's Carpenter's Square
Source Institutions
In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

All Wound Up
Source Institutions
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.
