Problem
Conservation of Mass Activity
Observe and analyze the interactions between the substances pictured in the slide show below. What observations can you make about the steel wool and oxygen in the first slide? How would you describe what they look like? How would you describe the product they make? Was mass conserved during the process (look at the sums of the masses)?
Provide your observations and analysis of the beginning substances and ending substances in the activity worksheet. If you are not sure what to include in your observations, read the first example in the chart of your worksheet.
