measuring mass is difficult without a scale. but you can make a simple balance using a clothes hanger to estimate mass (google how to make one). then balance know mass objects (ex. nickles) with selected unknown objects. for example to determine the mass of a wrist watch, you can use several money nickels because each nickel has a mass of exactly 5 grams. for larger items you can use can food because they have labeled masses on the outside. we realize your answers will be estimates and not exact by try your best to estimate accurately.
