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

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

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

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners work in small groups to match various marine animals with their different environments.

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

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

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 make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

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

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 first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

Heat makes some materials expand, and it makes others shrink.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

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.
