The scientific method begins with and hypothesis statement. This is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Éx: If i leave a cup of ice on the counter, then the ice will melt because the temperature in the room wasn't cold enough.
The independent variable would be the temperature, and the dependent variable would be the ice.
An experimental group is the group in an experiment where the independent variable is being tested and the changes are being recorded and observed. The control group is a group that is separated from the whole experiment and and where the independent variable in the experimental group can't effect the results of the control group.
PROCEDURES
1. Gather materials
2.Set up for your experiment
3.Determine dependent and independent variables
4.Determine controlled variable
Experiment with examples of hypothesis statements and a conclusion

After watching the video, think about whether it was a good or poor experiment. To do this you need to determine if it is controlled and organized. If so, its a good experiment.
