Hanging under eaves, tucked in the cracks on tree bark, hidden in tall grass, spiders and webs can be found nearly everywhere you look in late summer. Not all spiders spin webs, however. Some actively hunt for prey, scurrying over dirt in the garden or ambushing pollinators visiting flowers. Whether wanderers or web weavers, spiders abound in nearly every habitat on Earth, with estimates of one million individuals living in each acre of grassy field. There are about 2,500 spider species in North America, all different and each well adapted to its role as a small but effective predator.
Spiders are arthropods, which means that they have jointed legs and hard exoskeletons, as insects do. Continue reading Spiders: Web-Builders and Wanderers – Background
FOCUS: Spiders come in a variety of shapes, colors, and sizes, but they all share some specific characteristics: two body parts, a hard exoskeleton, eight legs. They all make silk, too, though not all weave webs. Here we take a close look at web spinners and wandering spiders, examine their anatomy, and consider their special adaptations. We’ll learn about their lives as small predators and scout outdoors for spiders and webs.
Objective: To begin to explore and ask questions about spiders.
A day or two ahead of time, gather a variety of spiders and put them in jars with perforated lids, only one spider per jar, and include a moist cotton ball and bit of vegetation in each jar. Give each small group of children a spider in a jar to examine, and ask what they notice and wonder about it.
Materials: live spiders in clear jars with perforated lids with moist cotton ball and bit of vegetation, only one spider per jar; magnifying lenses.
SPIDERS UP CLOSE
Objective: To observe closely and compare a variety of different live spiders.
Using the spiders in jars from the Introduction, encourage children to use their magnifiers to look closely at the different parts of a spider. Can they distinguish Continue reading Spiders: Web-Builders and Wanderers – Activities

SPIDERS ALIGNMENT WITH
NEXT GENERATION SCIENCE STANDARDS
The activities in this unit help children understand the basic concepts in the Disciplinary Core Ideas listed here. You can use the following list as a guide for lesson planning. These Disciplinary Core Ideas are taken from Grade Band Endpoints in A Framework for K-12 Science Education. Additionally, our activities give children opportunities to engage in many of the Science and Engineering Practices and reflect on the Crosscutting Concepts as identified in the Next Generation Science Standards.
