Classification Q1S1

7th Grade Q1, Seq 1 - How do scientists classify living things?

TermDefinition
Controlled experiment A lab investigation in which all the variables are kept the same except for the one that is changed.
Variables factors in a science experiment that are changed, controlled, or measured.
independent variable what the scientist manipulates or tests on purpose.
dependent variable the results that are measured/observed, the outcome.
Constant Factors that are controlled so that they don’t affect the dependent variable
field study A scientific study of free-living plants or animals in which the subjects are observed in their natural habitat without changing, harming, or altering the setting or subject.
Model A simplified representation of a system that are useful for studying systems that are too big, too small, or too dangerous to study directly.
Domain the highest level of scientific classification of organisms.
Archaea The domain of single-celled, prokaryotic organisms that include autotrophs and heterotrophs that are NOT bacteria.
Eukarya the domain of mostly multicellular eukaryotic organisms.
Bacteria the domain of single-celled organisms with prokaryotic cells that can be either autotrophs or heterotrophs and are NOT archaea.
Kingdom the second highest level of scientific classification of organisms.
Animal the kingdom of heterotrophs that are multicellular organisms that sexually reproduce.
Plant the kingdom of multicellular autotrophs that can reproduce sexually or asexually.
Fungi the kingdom of heterotrophs that can be either unicellular or multicellular and can reproduce either sexually or asexually.
Protist the kingdom that includes unicellular or multicellular organisms that can be either unicellular or multicellular and can reproduce either sexually or asexually.
Unicellular organisms that are made of only one cell.
Multicellular organisms that are made of more than one cell.
Autotrophs produce their own food for energy; use photosynthesis or chemosynthesis for energy.
Heterotrophs eat other organisms to get proteins and energy.
sexual reproduction reproduction that results in an offspring that is a mixture of both parents.
asexual reproduction reproduction that results in an offspring identical to the parent.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
