• A family made the observation that more expensive brands of popcorn seern to produce more popped kernels than cheaper brands of popcorn, In order to test this hypothesis, the family
conducted an experiment in which they followed the procedures below
• The family bought 2 differing brands of popcorn to test: Wilbur Bockenreder Popcorn and
PopWhisper.
• They measured 1 cup of kernels and popped 5 bowls of each type of popcorn, They ensured they
popped the popcorn for the same amount of time, used the same wattage microwave, and did not
have any other ingredients added to the kernels (butter, etc).
• They counted and recorded the number of unpopped kernels in each of the 10 bowls.
• As they analyzed the data collected, they were able to conclude that their initial hypothesis was
supported.
• They formed the conclusion that the more expensive brand of popcorn popped more kernels than
the cheaper brand of popcorn.
From this experiment, let's answer some questions,

Was this a controlled experiment?

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
