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.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this hands-on activity, learners track and record the passage of colored "pompom traits" through three generations of gingerbread people.

In this activity, learners make instant ice cream without using a freezer.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity, learners make balloon models of disease-causing bacteria.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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 activity, learners investigate the olfactory system by conducting several experiments.

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 activity, learners will work together to create a program to navigate a Remotely Operated Vehicle (ROV) through an obstacle course.

In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.

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

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

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 nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels
