- Measurement
- Measurement is the size, capacity, or amount of something. It is used to record, compare, and describe things.
- survival
- Survival is to remain alive.
- muscles
- Muscles are animal body tissue that can contract and produce movement.
- cold-blooded
- Being cold-blooded is having a body temperature that changes with the temperature of the surrounding air or water.
- nervous system
- The nervous system carries information from the brain to the body and from parts of the body back to the brain. The nervous system controls the actions of the body.
- evidence
- Evidence is what a person observes, reads, or does, that strengthens a belief that something is true. It is important to know what the evidence is for a person to write statements or talk about science investigation.
- data
- Data is the information or facts collected in a scientific investigation.
- parasitism
- Parasitism is a relationship between two different organisms that is beneficial to one organism and harmful to the other organism.
- decomposer
- A decomposer is an organism that gets its food by breaking down once-living things.
- single cell organism
- A single cell organism is a plant or animal that is made of only one cell.
- natural balance
- Natural balance in nature refers to the steady condition of organisms in an ecosystem.
- growth
- Growth is the process of growing.
- evaporation
- Evaporation is the process by which liquid water changes into a gas called water vapor and enters the atmosphere.
- conclusion
- The conclusion is the part of the scientific method that should relate directly to the purpose statement. It summarizes the results of the experiment.
- observation
- An observation is the careful and thoughtful gathering of information by the senses.
- blood
- Blood is the red liquid that flows through the circulatory system.
- invertebrates
- Invertebrates are animals without a backbone.
- population
- The population of an ecosystem is made up of all organisms, plants, and animals.
- symbiosis
- Symbiosis is a relationship between two different organisms that is beneficial to both organisms.
- circulatory system
- The circulatory system controls the movement of blood to and from all parts of the body. It contains the heart, the blood, and the vessels.
- stages
- The stages of succession are the sequence of changes over time where plant and animal communities replace other plant and animal communities.
- producer
- A producer is an organism that makes its own food. Plants are producers.
- succession
- Succession is the changes that take place in an ecosystem over a long period of time.
- transport
- To transport is to carry from one part of the body to another.
- pioneers
- Pioneers are the first trees to germinate and grow in a young forest.
- bones
- Bones are the hard material that forms the skeleton.
- predator
- A predator is an animal that hunts and eats other animals.
- ecosystem
- An ecosystem is a community of organisms and interactions within the community.
- water cycle
- The water cycle describes the continuous movement of water from the oceans, lakes, ponds, rivers, and streams to the atmosphere, precipitation (rain, snow, etc.) to the Earth's surface, and finally, runoff through streams and rivers back to the oceans, lakes, ponds, rivers, and streams.
- heart
- The heart is a large involuntary muscle that pumps the blood through the circulatory system.
- endocrine system
- The endocrine system is made up of ten glands that secrete substances (hormones) into the circulatory system. The endocrine system controls body functions.
- warm-blooded
- Being warm-blooded is keeping about the same body temperature even when the outside temperature changes.
- dependence
- Dependence in ecosystems is the reliance upon the survival of other organisms for the needs for life.
- classification
- Classification is the process of grouping things based on their similarities.
- vertebrates
- Vertebrates are animals with a backbone.
- fair test
- A fair test is not favoring one over another. A scientific fair test is a procedure or investigation that is used on two or more subjects in the same manner.
- multicellular organism
- A multicellular organism is a plant or animal that has more than one cell.
- repair
- To repair is to put something back in good condition.
- skeletal system
- The skeletal system is the human framework made up of bones and joints.
- respiratory system
- The respiratory system brings oxygen to the body and takes carbon dioxide away from the body.
- theory
- A theory is an idea used as a starting point for a discussion or an investigation.
- prey
- Prey is an animal that is hunted and eaten by other animals.
- hypothesis
- The hypothesis is a step in the scientific method where a statement is written that supports an idea. It should be based on research and personal experiences and observations.
- digestive system
- The digestive system breaks down food into nutrients for the body.
- competition
- Competition is a relationship between organisms where different organisms compete for the same needs of life.
- climax community
- A climax community is when an ecosystem remains unchanged over a long period of time and there are no disturbances in the climate.
- nutrients
- Nutrients are the parts of food used by the body for life.
