What standard unit of measure is used by a scientist to measure the temperature of a substance?
What do scientists use to make observations or to gather information about the world?
by using their five senses
You think the sound in the front yard is your friend arriving to spend the night. Is that an observation or inference?
What is information collected through an observation called?
evidence or data
What are the 8 levels of classification of living things?
Scientists call the 8 levels of classification top heavy because there are many more organisms at the _____ level. Scientists relate the classification system to _______________ (geometric shape) this reason?
- an upside down triangle
You think the huge pine tree is leaning toward the center of the yard to compete for the little light available in your wooded backyard. Is that an observation or an inference?
Why do organisms share similar classification levels?
The more classification levels they share the more characteristics they have in common.
In what ways do scientists display data to share with others?
- line graph
- pie graph
- bar graph
- data tables
- making models
True or false: Plants are autotrophs.
What important ingredients do scientists include when making a graph to share with others to?
capitalized/centered titles, 2 subtitles, zero on graph, increments to fit data, plot or connect points and color in data
Why are viruses great messengers of genetic information?
Because of their ability to enter cells
Looking out your window you notice your neighbor's dog sitting in the back yard. Is that an inference or an observation?
What is a change in an organism's surroundings that causes the organism to react?
What level of classification is where organisms mate with like or similar organisms?
What is an action or change in behavior that occurs as a result of a stimulus?
What do scientists call getting bigger?
What is the process of change that occurs during an organism's life to produce a more complex organism?
What are 4 basic needs of living things?
- 1. water
- 2. energy
- 3. living space
- 4. stable internal conditions
Why do scientists put things into groups in an organized way?
so the organisms are easier to study
What are 6 characteristics that living things share?
- 1.cellular organization
- 2.contain similar chemicals
- 3.use energy
- 4.grow and develop
- 5.respond to their surroundings
What are the names of the 3 domains?
Viruses need energy to __________.
How do scientists place organisms into kingdoms?
- 1. Based on their types of cells,
- 2. their ability to make food
- 3. and the number of cells in their bodies
What are the 4 kingdoms that living things are placed in?
What do scientists call organisms that CAN make their own food?
Autotrophs use the ____ 's ______ to help make their own food to use as an energy source to carry out life's functions.
What is an animal called that can NOT make its own food? It uses the sun's energy in an indirect way. They eat stored energy in autotrophs or heterotrophs.
What are characteristics that plants have in common with other plants?
- multicellular eukaryotes
- make their own food
- life exists on earth because of them
Why are bacteria called decomposers? Why are bacteria so important on earth?
Decomposers are "nature's recyclers." They return basic chemicals to the environment for others thing things to reuse.
Why are viruses considered nonliving?
They are NOT cells
Viruses only need energy to _____________.
Why are viruses used in gene therapy?
Scientists take advantage of a viruses ability to get into a host cell.
Why do scientists now classify organisms into more than just the plant and animal kingdom?
(The domain level was added for this reason)
The use of the modern technology, especially use of a high powered microscope, led to the discovery of many new organisms and the identification of differences among cells.
What 2 ways are bacteria harmful?
- 1. cause illness/infectious diseases
- 2. cause food poisoning
What are some ways that are bacteria helpful?
- fuel production
- food production
- oxygen production
- environmental recycling
- environmental cleanup
- production of medicines
- food preservation
What are 3 common conditions that promote the growth of a common fungi or bread mold?
- ***Mold needs water, food (bread) and a place to grow (a dark, warm place)
How would you recommend food be stored after completing the bread lab?
Store food in cool, dry places to prevent the growth of mold.
What are some common food preservation techniques?
- silica packets
