Wednesday, 4-15-15 Warm up: Butterfly Disguise Rules of contest: 1. Color FIRST 2. Cut out the correct size 3. The whole butterfly must be visible 4. The location must be visible, not hidden behind an object 5. A predator will come to pick off those that are not fit to the environment 6. Prizes for winners © A. Weinberg Agenda: 1. Notes adaptations 2. Poster walk 3. Zingy 11.9 done? 4. Natural Selection game/ Biodiversity activity Draw and label the structures of a fish that allow it to move underwater. Gills Fins Scales Streamlined body © A. Weinberg 2013 Science Teacher Pro toad Adaptations: Physical traits and behaviors that enhance an organism’s survival © A. Weinberg Animals have certain adaptations that help them to survive. Zebras confused predators with their stripes. © A. Weinberg Physical adaptations are body structures that allow an animal to find and consume food, defend itself, and to reproduce its species © A. Weinberg © A. Weinberg Physical adaptations help an animal or plant survive in its environment. Physical adaptation Camouflage (use of color in a surrounding) The chameleon can change its color to match its surroundings. Can you do that? © A. Weinberg Physical adaptation Mimicry (looking or sounding like another living organism) The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart? I’m the Viceroy! Not poisonous Poisonous I’m the Monarch! © A. Weinberg Physical adaptation Chemical defenses (like venom, ink, sprays) An octopus squirts out ink to escape predators © A. Weinberg Physical adaptations Body coverings: armor plates, fur, feathers, shells, scales © A. Weinberg Physical adaptations Body parts (claws, beaks, feet, skulls, teeth) The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick things up. © A. Weinberg Physical adaptations Adaptations of leaves, stems, and roots Leaves: Food storage Onion=bulb © A. Weinberg Leaves: Protection Cactus=spines Stem: Climbing/support Grape vine=tendril © A. Weinberg Root: Support Corn=prop roots Behavioral adaptations are organisms’ actions. Remember that Physical Adaptations are body structures of animals or plants. Each organism has unique methods of adapting to its environment by means of different actions. © A. Weinberg We can divide Behavioral Adaptations into two groups: Instinctive Learned These behaviors happen naturally & don’t have to be learned. These behaviors must be taught. © A. Weinberg Learned behaviors Chimpanzee using a stick to get insects © A. Weinberg = Obtained by interacting with the environment and cannot be passed on to the next generation except by teaching. Nomadic: Polar bear needs to search for food (roams all over) Swarming: Fish use as a defense against predation © A. Weinberg Nocturnal: active at night BurrowerDigs holesMole © A. Weinberg Food Storage: some hide food away; some store fat Hibernation: deep sleep through winter Migration: Wildebeest follow the rainfall patterns © A. Weinberg Arboreal (live in trees) © A. Weinberg Night Blooming Some desert plants have flowers that open at night because there are more pollinators active during the cool hours. © A. Weinberg Other responses to environmental stimuli: Lean towards light (phototropism) Shed leaves (apoptosis) Flower Lean away from loud music © A. Weinberg Katydid False Eyes This insect has two false eyes that act to scare away predators. As a predator is approaching, the katydid opens its wings to reveal the eyes. The predator may believe that they are eyes one of its own predators and will avoid them. © A. Weinberg 2013 Science Teacher Pro Atlas Moth The wings open up to reveal a pattern that is similar to snake skin. In nature, many organisms are afraid of snakes so this pattern may make the predator turn right back around. © A. Weinberg 2013 Science Teacher Pro Deilephila Moth This moth hides among similarly colored plants by day and does not fly until well after dark. The moth will travel to species of plants that have the red and orange color of its body. © A. Weinberg 2013 Science Teacher Pro Flatfish Flatfish can flatten their bodies and lay on the bottom of the sea floor waiting to snatch at passing prey. Some species can even rotate their other eye so that both are looking up! © A. Weinberg 2013 Science Teacher Pro Butterfly Fish Butterfly fish have a false eye on both sides of its body. This feature serves two purposes. 1.False eye is large and on the back 2.Real eye is hidden by a black stripe © A. Weinberg Eye Stripe False Eye 2013 Science Teacher Pro Iguana Can you see him? Many of its prey can not. This lizard uses camouflage to blend into the surroundings while hunting his prey. 2013 Science Teacher © A. Weinberg Pro Kill Deer Eggs Kill Deer eggs look like and they lay them in gravel If anything gets close to the young the mother will appear injured by dragging their wing across the ground and limping. Predators will think it’s injured and follow it but the bird stays just one limping step in front of them…the entire time they are leading the predator AWAY from their young. Once they are far enough away the faking bird will 2013 Science Teacher © A. Weinberg fly away. Pro Leaf Insect Small insects like this one are often a favorite food for many animals. This insect protects itself by mimicking a green leaf. You can even see the fake leave veins on its body. © A. Weinberg 2013 Science Teacher Pro Just Some Cool Animals You May Not Know About: What do you think their adaptations are for? Mongolian Mickey Mouse! Bask Shark! Purple Frog! © A. Weinberg
