Habitats/Adaptations Habitat—Place where plants and animals can live and survive. Behavioral Adaptation—How something acts. Physical Adaptation—How something looks. Hibernation—When an animal sleeps for the winter. Dormancy—When a plant “sleeps” for the winter. Migration—When animals travel to another place to find shelter or food. Camouflage—Helps an animal blend into its surroundings. Mimicry—When a plant or animals acts or looks like another of its kind to protect itself. Habitats: Water Related Environments o Pond o Marshland o Swamp o River o Ocean Dry Land Environments o Desert o Grassland o Rainforest o Forest Aquatic food chain Instinct—Something you are born with/knowing how to do. Learned Behavior—Something you are taught. Not born knowing. Producer—Makes own food. Terrestrial food chain Consumer—Something that eats another thing. Decomposer—breaks down dead organisms. Herbivore—Eats only plants Carnivore—Eats only meat Omnivore—Eats both plants and animals. Predator—the hunter Prey—the hunted Matter Scavenger—eats animals that have been skilled by other animals for food. Sun is the beginning of all food chains. Everything is made of one or more materials that can be described by their physical properties. A physical property is what they look like. Materials/things are composed (made up) of parts that are too small to be seen without magnification. Physical properties remain the same as the material is reduced in size. Soil Sources of Energy Weathering—The process by which rocks are broken down into small grains and soil. Weathering can happen through rainfall, ice formation, or the action of living things, such as algae and plant roots. Sunlight—produces light and heat energy—is renewable Erosion— the wearing away by water, glaciers, wind, waves, etc. Wind--renewable Humus—Decayed plants and animal matter that provides nutrients to the soil. Is part of the topsoil layer of soil and is not a layer of its own. Water--renewable Wood—non-renewable Fossil Fuels—non-renewable—fuels that come from nature: Natural gas, coal, oil Renewable Resource—can be used over and over again. Non-Renewable Resource—cannot be reused -The kind of soil formed depends on the kind of rock that weathers. -Clay is a type of soil that holds water very well, where sand is a type of soil that does not hold water well. -Soil is a natural resource that needs to be conserved (saved). Topsoil—Top layer of soil and is a natural product of bedrock and subsoil. Earthworms, humus, and plant roots are usually found here. Subsoil—Is the “middle” layer of soil, has some rocks. Bedrock—The bottom layer of soil and is made up of mostly solid rock. -Small spaces in the soil hold nutrients, water and air that plants need to grow. -Soil helps plants by providing both nutrients and support. Topsoil Subsoil Bedrock Simple Machines Force—Push or pull that causes something to move. Types of Force: Wind, water, windup, gravity, magnetic, electricity, push and pull. Mass—the amount of matter that makes up an object. Weight—the measure that tells how much gravity pulls on an object. Gravity—the force that pulls things towards earths center. Work—the act of movement. Simple Machine—a machine used to help make work easier. Types of Simple Machines— Wheel and Axle: Cycles The Moon Cycle The moon is made of rock The earth has one moon Orbit means to go in a path of revolution The moon revolves around the earth. The moon has 8 phases In moon phases—“Waxing” means getting bigger. In moon phases—“Waning” means getting smaller. The moon is illuminated by the light of the sun. It takes one month for the moon to revolve around the earth. The Tide Cycle Tides are caused by the gravity of the moon There are 2 high tides and 2 low tides each day The Water Cycle Example of animal life cycle Processes involved in the water cycle o Evaporation o Condensation o Precipitation Also know run off and ground water We need to conserve water o Conserve means to use wisely Heat from the sun drives the water cycle Water is essential/important for all living things The following diagram: Example of plant life cycle The Sun Condensation Precipitation Evaporation Other Cycle Info. Earth is tilted We have four seasons o Summer o Fall o Winter o Spring A cycle is a natural event that happens over and over again It takes the Earth 365 days to revolve around the sun We have 4 seasons because of the tilt of the Earth’s axis The Earth’s rotation on its axis every 24 hours causes day and night
