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 help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.

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

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

In this activity, learners separate the protein from milk and and use it to make their own glue.

In this activity, learners use sets of cards to assign microorganisms to different groups.

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

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.

In this activity, learners play a matching game with their families to discover common inherited traits and traditions. Learners distinguish between inherited traits and learned traditions.

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.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity, learners will explore trends in Canada goose populations using real data from the National Audubon Society's Christmas Bird Count.

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 design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

Throw that fish back? A new generation of ethical anglers concerned about conserving resources is participating in "catch and release" fishing. How is this going?

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

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.
