In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

In this math activity, learners use gingerbread cookies to collect and organize simple data. First, learners read "The Gingerbread Boy" by Paul Galdone.

In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.

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.

In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

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.

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