Initial perceptual naive misconceptions (any age)

Misconceptions (Explanations, Naive understanding, Misconceptions, or Perceptual responses)

Organisms

  1. Any object that moves is living. (Machines, smoke, clouds, fire, moving water...)
    Non living is dead.
  2. Plants are not living.
  3. Living and growing movement makes an animal alive, a seed is dead, all living organisms make noise.
  4. Plants are not alive. because they do not move…
  5. Students will sometimes say that plants breathe and grow but still do not see them as alive.
  6. Need to talk, walk, or breathe to be alive
  7. Can't link the same properties that are associated with animals being alive to plants.

Plants

  1. Plants are not living
  2. Plants absorb food through their roots.
  3. Oxygen, Carbon dioxide, water, minerals is food
  4. Seedlings are plants or living, trees are not
  5. Grass, trees, and other plants die in the winter and are born in the spring
  6. Plants eat artificial food, nutrients, water
  7. Plants bring up soil, water, minerals to get food
  8. Need sugar to survive.
  9. Leaves change color because they don't have much moisture, get dry, and turn brown
  10. The temperature changes and leaves can't survive so they drop off.
  11. Trees hibernate like animals.

Microorganisms and disease

Beginning (preschool - 7 years)

Concepts

Organisms , Behavior, Diversity, Adaptation, and Survival

  1. Plants and animals are the same and different.
  2. Organisms need food, water, and shelter to survive.
  3. The behavior of individual organisms is influenced by internal cues (such as hunger) and external cues (such as changes in the environment).
  4. Plants and animals have features that help them survive in different environments.
  5. Stories sometimes give plants and animals properties they do not have.
  6. Humans and other organisms have senses that help them detect internal and external cues
  7. Each plant and animal have different structures that serve different functions in growth, survival, and reproduction (humans have distinct body structures for walking, holding, seeing, and talking)
  8. Different plants and animals have features that help them live in different places.
  9. Some kinds of organisms that once lived on Earth have completely disappeared.

Reproduction and Life Cycles

  1. Plants and animals reproduce plants and animals similar to their parents.
  2. Plants and animals have life cycles that include being born, developing into adults, reproducing, and eventually dying.
  3. Plants and animals closely resemble their parents but not exactly.
  4. There are differences among individual organisms of a species.

Clone

  1. A clone is in many ways like identical twins. They have the same DNA, they may look the same but they have unique experiences and memories. They are two different people.

Microorganisms and disease

  1. Plants, and animals (people are animals) get infections from other organisms (germs).

Intermediate (7 years - 11 years)

Concepts

Organisms , Behavior, Diversity, Adaptation, and Survival

  1. All living organisms use - metabolize food for energy - to move, respire, use water, reproduce, respond to the environment (sensitivity), grow, excrete waste, require nutrition.
  2. All living organisms have basic needs, (animals need air, water, food, and shelter; plants need air, water, nutrients, light, and shelter).
  3. Organisms can survive only in environments in which their needs can be met.
  4. Living organisms can be sorted into groups in many ways by their common properties.
  5. Properties used for grouping depends on the purpose of grouping.
  6. Internal and external features are used to classify organisms.
  7. Adaptation is a change in a species or individual that improves its condition or relationship to the environment.
  8. Organisms must have their basic needs met to survive.
  9. Organisms must have optimum ranges of food, light, heat, water, and shelter met to survive.
  10. All species are different.All organisms have similar needs and structures.
  11. Organisms must have their basic needs met to survive.
  12. Organisms must have optimum ranges of food, light, heat, water, and shelter met to survive.
  13. Species must reproduce to survive.
  14. Some organisms that lived long ago are similar to organisms that live today while others are different.
  15. Some individual differences provide better opportunities for surviving and reproducing.
  16. Extinction means there are no living organisms of a certain species.
  17. Adaptation is a change in a species or individual that improves its condition or relationship to the environment.

Reproduction, Life Cycles, and Heredity

  1. Species must reproduce to survive.
  2. A species includes all organisms that can mate with one another to produce sexually fertile offspring.
  3. Organisms are collections of cells.
  4. Cells continually divide to make more cells for growth and repair.
  5. Important levels of organization for structure and function include cells, organs, tissues, organ systems, and organisms.
  6. Similarities among organisms internal features infer a degree of relatedness among them.
  7. The human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control and coordination, and for protection from disease.
  8. These systems interact with one another.
  9. Groups of specialized cells cooperate to form a tissue, such as a muscle.
  10. Different tissues are grouped together to form larger functional units, called organs.
  11. Each type of cell, tissue, and organ has a distinct structure and set of functions that serve the organism as a whole.
  12. Each different organism has a life cycle that is different from other organisms Plants and animals may change in appearance a little or a lot as they grow.
  13. In many species, including humans, females produce eggs and males produce sperm, plants also reproduce sexually, the egg and sperm are produced in the flowers of flowering plants.
  14. An egg and sperm unite (fertilization) to begin development of a new individual.
  15. That new individual receives genetic information from its mother (via the egg) and its father (via the sperm).
  16. Sexually produced offspring never are identical to either of their parents.
  17. Many characteristics of an organism are inherited from the parents of the organism, but other characteristics result from an individual's interactions with the environment.
  18. Inherited characteristics include the color of flowers and the number of limbs of an animal.
  19. Other features, such as the ability to ride a bicycle, are learned through interactions with the environment and cannot be passes on to the next generation. This infers a way to transfer genetic information from one generation to another.

Microorganisms and disease Concepts

  1. Microorganisms can cause disease.
  2. Disease is essential to decompose organism.
  3. Decomposition is a way to recycle materials.
  4. Most microorganisms do not cause disease and many are beneficial.
  5. Disease is a breakdown in structures or functions of an organism.

Literate (11+)

Concepts

Organisms , Behavior, Diversity, Adaptation, and Survival

  1. Organisms have been classifed into six kingdoms: Archaebacteria, Eubacteria, Protist, Fungi, Plant, and Animal. These classes can also be goupred as viral and nonviral life. With nonviral classified into three groups 1. complex organisms with nucleated cells: eukarya / eukaryotes (protists, plants, algae, fungi, & animals) 2.bacteria, and 3. archaea. Prokaryotes incude both bacteria and archaea. Prokaryotes have no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single strand of coils or loops. Lokiarchaeota appears between archaean and ekaryotes.
  2. Living systems and ecosystems at all levels of organization demonstrate the complementary nature of structure and function.
  3. Animals consume energy and plants use sunlight to make their food.
  4. Some organisms can not be easily classified as only a plant or animal.
  5. All organisms are composed of cells, the fundamental unit of life.
  6. Two-thirds of a cell is water.
  7. Most organisms are single cells; other organisms, including humans, are multicellular.
  8. Cells carry on the many functions needed to sustain life.
  9. Cells take in nutrients to provide energy for the work that cells do and to make the materials that a cell or an organism needs.
  10. Specialized cells perform specialized functions in multicellular organisms.
  11. An organism's behavior evolves through adaptation to its environment.
  12. How a species moves, obtains food, reproduces, and responds to danger are based in the species' evolutionary history.
  13. Millions of species of animals, plants, and microorganisms are alive today. Although different species might look different, the internal structures among organisms is similar, their chemical processes, and common ancestry. Biological evolution explains how the diversity of life and the uniqueness of each species' properties developed through a slow processes over many generations through biological adaptation, which involves the selection of naturally occurring variations in populations, which include changes in structures, behaviors, or physiology that enhance survival and reproduction success in a particular environment.
  14. Small differences can accumulate in successive generations so that descendants are very different from their ancestors. Individual organisms with certain traits are more likely to survive and reproduce. Changes in environment can affect the survival of individuals and entire species.
  15. Extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient to allow its survival.
    Fossils indicate that many organisms that lived long ago are extinct. Extinction of species is common; most of the species that have lived on the earth no longer exist.

Reproduction, Life Cycle, and Heredity

  1. A species includes all organisms that can mate with one another to produce sexually fertile offspring.
  2. Organisms are collections of cells.
  3. Cells grow and divide - thereby producing more cells.
  4. Reproduction is a characteristic of all living systems.
  5. No individual organism lives forever. Therefore, reproduction is essential to the continuation of every species.
  6. Some organisms reproduce asexually and other organisms reproduce sexually.
  7. Genetic characteristics are passed from only one parent (asexual) or two parents (sexual) reproduction.
  8. Every organism requires a set of instructions for specifying its traits.
  9. Heredity is the passage of these instruction from one generation to another.
  10. Heredity information is contained in genes, located in the chromosomes of each cell.
  11. Each gene carries a single unit of information.
  12. An inherited trait of an individual can be determined by one or by many genes, and a signal gene can influence more than one trait.
  13. A human cell contains many thousands of different genes.
  14. New varieties of plants and animals have been cultivated through selective breeding and gene splicing.

Microorganisms and disease

  1. Most microorganisms do not cause disease and many are beneficial.
  2. Disease is a breakdown in structures or functions of an organism.
  3. Some diseases are the result of intrinsic failures of the system.
  4. Others are the result of damage by infection of other organisms.
