Record the weight of the object when submerged in water, by attaching it to a spring balance. Determine the weight of the liquid displaced and compare it to the apparent weight of the submerged object due to the buoyant force. The weight loss of the submerged object should be equal to the weight of water displaced. Repeat for an object which floats. Carefully examine how the apparent loss in weight of a floating object compares to the weight of the liquid it displaces.
More sugar is added, if necessary.
The starting specific gravity determines the potential alcohol yield. Perform an activity to investigate the specific gravity of sugar solutions at different concentrations. Research wine making and the historical aspects of wine making. It has important scientific, social, technical, historical, and economic aspects. In teams, make small batches of wine.
