In this story time program, young learners listen to the Dr.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.

In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.

In this math activity, learners estimate how many pennies are in a jar by predicting and counting handfuls of pennies.

In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system.

In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

In this activity (on pages 16-21), learners get a sense of geological time by understanding how big a million is.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this math lesson, learners compare products to determine the best product.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
