Spider Web Lesson Plan Name: Subject: Science Date: Grade: grade one Content: (Topic) spider webs (habitats) Teaching Strategy: questioning student-involved demonstrations Learning Objectives/Outcomes: to understand how and why webs are built Assessment: I will ask a series of questions to understand students’ knowledge Adaptive Dimension: Common Essential Learnings (CEL’s): Communication students will learn terminology about spider webs and this will improve their language abilities Prerequisite Learning: none required Lesson Preparation: Equipment/materials book: Anansi Goes Fishing by Eric A. Kimmel yarn fact sheet & pictures paper for the craft Advanced preparation: Presentation: Set (5-8 min) Classroom Management Strategies read the book Anansi Goes Fishing by Eric A. Kimmel. It is a West African trickster tale about the origin of spider webs Ask for predictions of what the book is about Read the book Discuss the book-what liked? What noticed? Development (15-20 min) Show students the pictures and tell them the facts on the fact sheet Make a class spider web Split into two groups (approx. 8 students each) Each group gets into a circle One child starts with the yarn ball. Pass the ball around the circle. Remind students to keep a hold on the yarn as they pass the ball to the next person Once the yarn has been passed to each student and a circle has been made, students pass the yarn to another student on the other side of the circle Say student’s name so know yarn ball is coming their way Keep passing the yarn until you have a complete spider’s web (teacher decides when done) Set web carefully on the ground being sure to keep holding onto the yarn. Take a picture of your class web Compare your web with the pictures of the real webs. Discuss findings Closure (15 min) Student will take part in an art activity were they will create a spider’s web on paper. Using crayons or markers, students will draw a spider’s web Students will draw a picture of prey they caught on their web Extensions: Do the activity again and see what your new spider’s web looks like. Compare the two. The art activity could be done with yarn and glue. Facts Sheet A spider’s web is also known as a cobweb. This comes from the old-fashioned word coppe, meaning “spider” and is sometimes in connection with the idea of a dusty, abandoned web. (Wikipedia, 2009a) Spider’s webs are built out of a proteinaceous spider silk. This silk is extruded from a spider’s spinnerets. (Wikipedia, 2009a) A spinneret is a spider’s silk spinning organ. It is located on the underside of a spider’s abdomen, to the rear. Spider’s can have anywhere from one to six spinnerets but the majority have six. (Wikipedia, 2009b) Webs are built for many reasons. Some are built for catching prey. Others are used to make spider’s homes and to protect their eggs. (The Earth-Life Web, 2009) Only about half of the worlds spiders spin webs to catch prey. The rest are hunters who either stalk their prey or lay in ambush waiting for their prey to come along. (The Earth-Life Web, 2009) Not all spiders build webs. (Wikipedia, 2009a) Because spider silk requires so much protein, spinning a web is an extremely costly process. After a time, webs lose their stickiness so spiders will eat their own webs daily to regain some of the energy lost and then will rebuild a new web. (Wikipedia, 2009a) The strength of tension in spider silk is greater than the same weight of steel. The silk also has more elasticity. Scientists are looking at how it is made up for possible application in industry, including bullet-proof vests. (Wikipedia, 2009a) References: The Earth-Life Web. (2009). Introduction.
