Transcript: In this 2nd Grade unit, the students will learn all about camouflage. For two weeks, they will engage in fun activities that pertain to all different kinds of animals who learn to blend into their environment. They will learn new vocabulary pertaining to the topic. They will also have the chance to be creative based on what they learned throughout the unit. Objectives 1 The students will watch the introductory video (Leopard stealth) and through group discussion, find 3 key points about the leopard in the video to type a short Power Point summary. 2 As a class, students will watch a portion of “Kings of Camouflage” and discuss what they observed the cuttlefish do, taking notes of all the key points the teacher mentions (which will also be displayed on the whiteboard). The students will then get into pairs to use Microsoft Word to create a Venn Diagram that compare and contrast the animals listing at least four differences and one similarity between the animals in regards to their environment and food source. 3 After the teacher has read 3-D Close Up: Animal Camouflage, the students will search online in groups for different kinds of camouflaged animals through child-friendly sites. The students will individually create “Inspiration” maps based on 2 different camouflage animals they choose and include 2 descriptions of each (one of their habitat and one of how they camouflage). 4 Individually, the students will create a camouflaged animal of their own on Kidpix using the lesson vocabulary to 1) describe what kind of animal it is, 2) how it camouflages, and 3) what kind of environment it lives in. 5 Individually, students will create a habitat that corresponds to the animals that they had previously created with KidPix and should include 2 things- food source, shelter/hiding place.

Camouflage

Transcript: Have you ever been outside and noticed how some animals blend into their surroundings? In today’s lesson, we’ll think about how they do that and how that might affect their survival. Share your answers with your group. What does camouflage mean? 1. What helped the moths survive? 2. Why did some moths survive while others perished? 3. How will the offspring of the survivors appear? What will they look like? 4. What are some advantages and disadvantages of camouflage as a survival strategy? How hard will it be to find the offspring of the survivors? Why? What is it called when traits are passed down to offspring that help them survive? 1. England’s industrial revolution gradually coated the countryside with dark soot from factories. How did this affect moth coloration over time? 2. Go outside and see if you can find examples of camouflage. How many moths were found? Now we are going to color in our moths. Try and camouflage them around the classroom. Rules: a. Moths must be visible from the center of the room. b. You may not put the moths under or behind things. c. You may not put them on the ceiling or outside a window. Then the Hungry Birds are going to try and find as many as they can in one minute! Answer in your journals: How can you hide paper moths in plain sight in the classroom? http://www.online-stopwatch.com/full-screen-stopwatch/ Camouflage Other examples of Camouflage Natural Selection! What questions do you have about the importance of camouflage?
