Choose the DV: Eggs were placed in containers with and without salt to determine how high they would float. What's the DV?
independent variable
height the eggs floated
amount of salt
constant
If more salt is added to water, then the higher the egg will float.
increasing the temperate of water
observations made involving exact quantities and measurements are made
control
Which part of the investigation is kept the same and doesn't change throughout the experiment?
independent variable
height the eggs floated
amount of salt
constant
If more salt is added to water, then the higher the egg will float.
increasing the temperate of water
observations made involving exact quantities and measurements are made
control
Which part of the investigation is a comparison to the independent variable?
independent variable
height the eggs floated
amount of salt
constant
If more salt is added to water, then the higher the egg will float.
increasing the temperate of water
observations made involving exact quantities and measurements are made
control
Find the IV: If we increase the temperature of water, then the tablet will dissolve faster.
independent variable
height the eggs floated
amount of salt
constant
If more salt is added to water, then the higher the egg will float.
increasing the temperate of water

Choose the IV: One egg was placed in water without salt, one was placed in water with 2 tbsp of salt, and one was placed in water with 4 tbsp of salt. Make observations to see if the egg floats or not.
independent variable
