DON’T WASTE ANSWERS PLEASE :( 6. Read the following news article about a scientific experiment:
A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The
scientists pointed out that because beets grow underground, they continue to grow in freezing
conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter.
To test this hypothesis, the scientists froze equal volumes of water on two separate plates. They spread
an extract of beet roots on one plate of ice and sprinkled an equal amount of salt over the other plate.
After keeping both plates at 0°C (the temperature at which water freezes) for a period of time, they
measured the amount of melted water on each plate. Their results showed that the plate treated with
beet-root extract contained more liquid water than the plate treated with salt.

a) Summarize the steps of the scientific method by answering the questions in each box below. Use the
information from the passage to answer the questions. (5 points)

What is the question or problem? What question are the scientists trying to answer?

What is the hypothesis? What educated guess are the scientists making?

Make a prediction. Remember, a prediction is a statement of if the hypothesis is true, then...

What are the steps in the experiment?( list four steps) How did the scientists test the hypothesis?

What is a possible conclusion for the results of the experiment? How do the experimental data answer the question from the beginning?

b) What would make the results of this experiment reliable?

c) Would you recommend that the members of your city council use beet- root extract instead of salt to thaw icy winter roads? Explain your answer.
Please help anyone.
