method:
1.Make a floating boat
2.Float that boat in water
3. Add some paper clips in
4.Put some mass on
Conclusion: When i put alot of mass in the boat the boat just got in the water..
i want to know what is the variable and control of this science experiment

Variable: added weight of paper clips and mass
Control: The boat before the paper weight is added

The control is the substance without any additive. Example to test the effect of salt on water. The control is water the variables maybe a 10% solution of salt a 20% solution of salt and a 30% solution of salt. All four must be kept in the same environment from the beginning of the experiment until the end. If there is any change the control must also be tested to insure the environment did not have an effect. The sun, extreme heat, extreme cool, extreme moisture, extreme dryness etc could all effect the experiment but they should also effect the control if done properly.

the variable would be the added weight of paper clips and mass because it is the thing you are testing, and the control would be the boat before the paper weight is added, because it is constant, and you are going to compare it with the results.

Boat's displacement without the paper clips is the control. Displacement w/ paperclips is the variable.

Variable - increasing weight.
Control: None, there should be another boat to see if it sinks if you do nothing.
