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.

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.

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

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

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

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

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).

In this activity, learners explore the concepts of natural selection and observable traits in a game that can be played at home.

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.

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 will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

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
