In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

In this arts and crafts activity about animals and animal characteristics, learners will design animal hats and role-play as animals.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

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

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners explore the possibilities of clay as a natural material.

In this math lesson, learners rotate through various centers while comparing and ordering objects according to length.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this activity, learners set up a night time insect observation station with a light and sheet.

In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.
