about why our beloved penny should be removed from the currency system. We have all spent countless times digging through our wallets searching for change and waiting for our grocer or barista to give us back the meaningless pennies that will most likely end up in a tip jar or a penny tray. Sereno not only states that the penny no longer has value to society‚ but is more so of an annoyance to the US Mint system. I believe that society can most certainly do without the petty penny‚ regardless of the

of pasta noodle would hold the most pennies if we were to tape them to two stools 16 cm apart‚ dropping pennies into a cup tied around the noodle? Expiremental Variables - We will be able to identify the mass of a penny and how it can test the strength of a pasta noodle as a result of the downward pull of gravity on the penny. Test Variable: The type of noodle is what I’d be changing throughout the process Outcome Variable: I would be observing how many pennies each noodle could hold counting every

DETERMINATION OF % COMPOSITION OF PENNIES USING REDOX AND DOUBLE DISPLACEMENT (PRECIPITATION) REACTIONS Pre- Lab 8 Objective: The purpose of this experiment is to determine the percent composition of pennies using oxidation-reduction and double displacement reactions as well as titration techniques. We will take a post 1982 penny and place in a strong acid dissolving the zinc core and leaving behind the copper coating. We will figure out the percent composition from the mass of copper and zinc using

Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds‚ and when water is mixed with soap the polar bonds which help to bind the water together are weakened‚ thus lessening the surfacetension. Materials: pipette‚ liquid soap‚ water‚ beakers‚ penny‚ graduated cylinder

After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating was used in a particular penny. Not knowing the about information‚ my original hypothesis was that the penny would contain a great deal
