PLEASE HELP ASAP

You will design an experiment to explore one of the two following situations. Your experimental design should include the
-independent variable
-dependent variable
-constants
-measurements you would take
-data you would collect
Equipment and materials (include quantities)
-safety precautions you would follow
-general procedure (including equipment and amounts of materials you would use)

Create your experimental design using complete sentences and with correct grammar and spelling. You may use numbered steps for the procedure if you wish. Use SI units for measurements (mL, g, cm, etc…) and common laboratory equipment (graduated cylinder, balance, etc..) when possible
