In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

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

In this activity, learners will keep track of how much they can do in one minute. Instructors can pick something everyone will do for a minute, such as jumping up and down or drawing stars.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

This is an online activity about simple machines. Learners will try their hand at putting these amazing devices to work. They will use several simple machines to help "build" a tree house.

Learners make a counting/estimating jar to exchange with friends or bring home.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

In this quick activity about size and scale (on page 2 of the PDF under What's Nano?

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s
