What is the
importance of a
control in an
experiment?
How many variables
do you test at one
time during an
experiment?
Answer the following question regarding scientific experiments.
Harvester ants often strip a bush of all its leaves. Some people believe
this helps the plant grow thicker, healthier stems. In an experiment, a
student stripped off all the leaves from a set of plants. In a second set of
identical plants, the student allowed ants to strip off the plants’ leaves.
What needs to be added to the experimental design in order to improve
the overall experiment? How would you accomplish this task?
Read the following experiment and answer the
accompanying questions.
A student investigated the effect of radiation on
the germination of bean seeds. He thought
that exposure to radiation would limit the seeds
ability to germinate (grow) much like ultraviolet light causing skin cancer. Three hundred
seeds were soaked in distilled water for one
hour. They were then divided into three
groups. One group was placed in a microwave
oven on high for three seconds. Another group
was microwaved on high for six seconds. The
last group was not microwaved. The seeds
were then planted in three separate flats and
given the same amount of water. The flats
were placed in a location with constant
temperature of approximately 27 degrees
Celsius. Each day for two weeks the number of
seeds that germinated each group was
recorded.
Three sec of radiation: 54
Six sec of radiation: 26
No radiation: 88
