Anthropologists from the Newark Museum discovered a sealed pot while exploring an ancient pueblo in Arizona. In the pot, they found a tan substance that they had never found before (See Figure 1). Their first question was “Is it alive?”
In order to answer the question, they performed the following investigation.
Step 1: Place 5 grams of the substance and 20 ml of warm water into four sterilized water bottles.
Step 2: Place 1 gram of table sugar in bottle #2, 2 grams of table sugar in bottle #3, and 4 grams of table sugar in bottle #4. Bottle #1 did not have table sugar added.
Step 3: Place a non-latex balloon over the top of each bottle and shake gently.
Step 4: Measure the radius of the balloon each hour for 24 hours.
Step 5: At the end of the 24 hours, add Benedict's solution to determine if sugar is present in the solution.
