Patterns in Nature

Looking for Similarities and Differences

Patterns exist everywhere in nature. Early on we learn to recognize them, and they help us make sense of the world. It starts simply – noticing that night follows day, plants have leaves, animals move, and winter snows change to spring rains.

This recognition of repeating events and reoccurring structures and shapes naturally leads to our organizing and grouping things together and inspires us to look more closely. We recognize that insects are animals with six legs, the seeds of evergreen trees are contained in cones, and birds build nests every spring. Careful observation of similarities and differences within groups helps us further classify both living and non-living things. Snowflakes are all six-sided crystals, yet they can be sorted into categories by growth pattern and specific design. Insects, like butterflies, beetles, and grasshoppers, can be separated into easily recognizable orders based on their shared traits. And, while all leaves share a similar function, they can be differentiated by shape and venation patterns. Continue reading Patterns in Nature

All Sorts of Insects – Background

The world is full of all sorts of insects. You can find them everywhere you go, whether swimming in a pond, weeding your garden, playing on the playground, or enjoying a picnic lunch. It is said that there are 200,000,000 insects for every person on earth. Scientists have identified more than a million different kinds of insects. And they think there are millions more species still waiting to be discovered.

Insects belong to a group called arthropods. Unlike you and me, with our bony internal skeletons, an arthropod’s body is covered with a tough outer shell, or exoskeleton. This exoskeleton is divided into segments that allow the critter to move. In fact, the word arthropod means “jointed legs.” Arthropods include not only insects, but also centipedes, crustaceans, and arachnids like spiders, ticks, and mites.

All Sorts of Insects – Activities

FOCUS: Honeybees, grasshoppers, and butterflies are all insects, yet they look and behave very differently from each other. So what makes an insect an insect, and how is it different from other animals? Insects all share the same basic design of three body parts, six legs, wings, antennae, and compound eyes. Variations in the size and shape of these parts account for their great diversity. We’ll learn to recognize common groups of insects by their characteristic features and watch them outside as they go about their daily lives.

INTRODUCTION
Objective: To begin to explore and ask questions about insects.

Give a variety of adult insects in small jars to children to examine in small groups, and ask what they notice and wonder about them.

Materials: a variety of live adult insects collected in small jars, magnifying lenses.

BUILD AN INSECT
Objective: To construct and compare felt insect models and identify common features and differences in insect anatomy.

Ahead of time, create bags of insect parts using the five Build an Insect templates and a variety of craft materials. In every bag use the same material to represent Continue reading All Sorts of Insects – Activities
