8. Compare your results with other students’ results to confirm your findings. f. Follow a set of written instructions for a scientific investigation. # ' , $( Analyzing Data To communicate your results, set up your data clearly.

See the students’ results on the graph below. DkcX[he\7djiedekhi Explain how you think the line graph makes the results clear.

They determine if their prediction matched their results. They draw conclusions and try to explain their results. When you draw conclusions, you interpret observations to answer questions.
