The higher the temperature the faster the egg will cook. Identify the independent variable.
What is the temperature?
200
This is the variable that is used to measure the outcome of the experiment.
What is the dependent variable?
200

Convert 12000 ml to liters.

What is 12 liters?

200
These are the things in the experiment that are kept the same.
What are the controlled variables or constants?
200

Which instrument of measurement would one use if they wished to measure the volume of a liquid?

Graduated cylinder

200
Lemon trees that receive the most water produce the largest lemons. Identify the independent variable.
What is water?
300

These are the variables that are not changed. They can not be changed so the outcome is sure to come from the I.V and D.V.

What is the controlled variable or constant?

300

Convert 63.2 dekameters to meters

What is 632 meters?

An experiment is run to see if different wood beams can hold more/less weight.  The amount of weight until breaking is observed and and the splintering of the wood. What is qualitative and what is quantitative data in this experiment? 

Quality = observation of splintering 

Quantity = weight before breaking
