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.

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?

They have red on the bottom black on the top and gray in the middle to help them blend in with the nature.

FISH PLANTS INSECTS AND ANIMALS IS SOME OF THERE FOOD.THEY BITE INTO THE FLESH AND START SHAKING.

Transcript: Animal Camouflage know more about camouflage and their types, and how it applies in our lives. Chameleon Types of camouflage Immobility: This is the simplest form of camouflage and is not moving to blend with the environment. Coloration:Blend with the environment changing color Pattern:Adjust the texture pattern around us. 30/Oct./13 The camouflage can be used in the military or just wear clothes that are the color of our environment and we are practicing the camouflage. Camouflage in our lives Objective Camouflage is a natural technique used by both predators as prey. Basically, this technique involves blending into the environment not to be perceived. starry flounder caterpillar baron Ghost mantis CAMOUFLAGE Stone fish What is the camouflage?
Transcript: Camouflage SSSSS&M SHAPE SHADOW SILHOUETTE SPACING SHINE MOVEMENT SHAPE: MILITARY EQUIPMENT AND THE HUMAN BODY ARE FAMILIAR OUTLINES TO ALL SOLDIERS. THEY ARE INSTANTLY RECOGNISED wHEN IN CONTRAST WITH THE SURROUNDINGS. AN OBJECT CAN CAST A SHADOW IN SUN OR MOONLIGHT AND SHADOWS ARE EASILY RECOGNISED. SHADOWS CAN BE USED TO CONCEAL OBJECTS BUT IT MUST BE REMEBERED THAT THEY MOVE AS THE SUN OR MOON MOVES. WHAT IS CONCEALED BY MORNING MAY BE EXPOSED IN THE AFTERNOON. ANY OBJECT THAT IS SILHOUETTED AGAINST A CONTRASTING BACKGROUND IS CONSPICUOUS. SMOOTH, FLAT BACKGROUND SUCH AS WATER, SNOW, FEILD AND WORST OF ALL SKY, MUST BE AVOIDED. NATURAL OBJECTS ARE RARELY IF EVER REGULARLY SPACED. REGULAR SPACING DRAWS ATTENTION TO THE FACT THAT SOMETHING OTHER THAN A NATURAL OBJECT IS PRESENT. TO GIVE OFF or GLOW WITH LIGHT. TO BE BRIGHT WITH REFLECTED LIGHT. TO APPEAR BRIGHTLY OR STRONGLY; GLARE. SUDDEN MOVEMENT ATTRACTS THE EYE. SLOW DELIBERATE MOVEMENT IS MUCH LESS LIKELY TO BE DETECTED.
