Sci Meth 1
This is an educated guess.
This is a scientific process used to solve a problem.
The Scientific Method
This measures temperature.
Thermometer
A gram is equal to one unit. How many milligrams is equal to one unit?
1000
If you are to convert millimeters to kilometers what operation would you use? (this is the same as moving the decimal point one space to the left).
division
This is an issue that needs to be investigated.
A Problem
This is a designed test to solve a problem.
An Experiment
This measures length and distance.
Meter
10 units
Look at the picture of the cell.
What is represented by the 1? What does this part of the cell do?
The nucleus; it contains the cell's genetic materials.
This is what you are measuring in an experiment.
The Dependent Variable
This is a summary that explains if the data supports the hypothesis.
The Conclusion
This measures volume.
Liter
One Hecto equals how many units?
100 units
Look at the picture of the pyramid of energy in an ecosystem. Which level in the pyramid would most likely contain members of the plant kingdom?
D
This is collected from an experiment.
Data/results
THis is the one thing YOU CHANGE in an experiment.
This measures mass.
gram
1000 units
A biologist reported success in breeding a tiger with a lion, producing healthy offspring. Other biologists will accept this report as fact ONLY IF
1. the biologist included a control in the experiment
2. research shows that other animals can be cross bread
3. the offspring are given a scientific name
4. other researchers can replicate the experiment
Other researchers can replicate the experiment
This is the group in an experiment upon which changes are made BY THE SCIENTIST.
The Experimental Group
This is the group in an experiment that does NOT change.
The Control Group
Put the following in order from LARGEST to smallest: Centi, Deci, Kilo, Hecto, Milli, Deka
How many times smaller is a centi than a unit?
100 times smaller
The removal of the predator populations from an ecosystem would most likely result in
1. a decrease in all the prey populations
2. an increase in all the produce populations
3. an increase in ecosystem diversity
4. a decrease in ecosystem diversity
a decrease in ecosystem diversity
