What is another name for living and non-living things?
Living is biotic and Non-living is abiotic
Which step of the scientific method is considered an educated guess
Hypothesis
What is the IV and DV in the following example:
An experiment that tests how quickly different temperatures will dissolve sugar cubes
IV: Temperature of substance
DV: time it takes to dissolve sugar cubes
What is a common way scientists organize living and non living things ?
Classification Tree
What are the 5 kingdoms of living things?
1) monera
2) protista
3) fungi
4) Plantae
5) animalia
What is another name for a community of plants, animals, and other organisms interacting with each other and nonliving things in a particular environment
Ecosystem
What is known as a series of steps that help find answers or information to questions about the natural world?
The scientific method
What kind of relationship is given in the example: wind is one of the forces responsible for soil erosion
Abiotic and Abiotic
What does classify mean?
To classify things means to place them in different categories, or groups
1) Bacteria belong is which kingdom?
2) One-celled organisms belong in which kingdom?
3) mushrooms belong in which kingdom?
1) Monera
2) Protists
3) fungi
Give an example of an abiotic and biotic factor
- Abiotic- temperature, air, water, soil, rocks, minerals, light, etc.
- Biotic- trees, plants, animals, grass, bacteria
What are the 6 steps of the scientific method in order
1) question
2) Hypothesis
3) experiment
4) analyze
5) conclusion
6) communicate
Write a hypothesis for the given question:
How does level of activity affect one’s breathing rate?
IF the level of activity increases then the breathing rate decreases
What is the word that means: the science of naming and classifying organisms
taxonomy
What are two categories that plants are divided into?
- vascular
-nonvascular
What are three types of relationships that can exist in an ecosystem? Describe each
Biotic and Biotic
Two living things interacting with each other
Abiotic and Abiotic
Two nonliving things interacting with one another
Biotic and Abiotic
One nonliving thing and one living thing interacting with each other
What are control variables?
Variables that are kept constant throughout an experiment to ensure results are not affected by any other variable
Identify 2 control variables in the example:
-How does water affecct the size of a raisin?
- same type or brand of raisin
- same size of raisin to start
- same type of water to start
- same container
What is a taxon?
is another name for each level of the level of classification for the living things (ex. Species is a taxon, genus is a taxon)
What are two categories are monera split into?
archaebacteria
eubacteria
What are 7 characterisitics of living things?
Are made up of one or more cells
Breathe (plants take in co2 and release oxygen, animals are opposite)
Require energy(through some type of food)
Respond to their environment (move and respond to things around them)
Grow and develop (life cycle)
Reproduce (offspring/babies)
Excrete- get rid of waste ( we get rid of CO2)
What is the difference between independent and dependent variables?
Independent variable: The cause portion of the testable question, the variable you purposely change
Dependent variable: the effect portion of the testable question, the thing you measure
Describe our penny lab. What did we find out?
n our penny lab we worked through each step of the scientific method to find out what the maximum number of water drops you can fit on a penny without the water spilling
We made predictions, conducted the test, and found the range for three trials.
We knew if the range of data was a larger number than our experiment was less accurate.
After each trial, we thought of ways to improve our next trial by determining more variables we could control to ensure a fair test
With each new trial we found our results got more accurate because we took more care in ensuring we had taken into consideration all variables that may be affecting our results
We found out the results are more accurate when we control variables that may affect our results
In the end our range got very small showing we had accurate results.
Name all seven of the levels of classification of living things
What are the 2 categories of animals and what can be found in each
1) invertebrate-- worms, molluscs, sponges, antropods
2) vertebrates-- mammals, reptiles, birds, amphibians, fish
