Name
Events or steps usually happen in sequence or in a particular
order. If you can recognize and follow the sequence, you will
better understand what will happen next. Words such as first,
then, next, now, and finally help signal the order in which events
or steps occur.
Read the scientific method. Label each step of the scientific
method below.

Sequence
Scientifi c method is specifi c steps scientists take during an experiment.
Scientists try to answer questions they have by performing several tests. By
following a specifi c sequence during different experiments, they are able to
determine the answers to their questions.
1. Initial or First Observation: Scientists notice something and wonder why.
2. Gather Information: Scientists try to fi nd out more.
3. Hypothesis: Scientists take their initial observation and create a question
that can be tested. A hypothesis should make a prediction of the outcome.
4. Testing: Scientists will perform experiments and record data.
5. Draw a Conclusion: Using the information from their tests, scientists will
compare this data to their hypothesis to see if their prediction is correct or not.
1. Finally I conclude my hypothesis was correct. The birds made a nest to hold
their eggs.
2. Then I learned more from a book about birds laying eggs in the spring.
3. First I see two blue birds. One is fl ying from tree to tree. The other is
gathering twigs. It is springtime.
4. Next I observe the birds for a week. They choose a large tree branch. The
birds gather more twigs and start building a nest. I see three bird eggs.
5. I predict the birds will make a nest to hold their eggs.
At Home: Write a paragraph explaining why it is important
for scientists to follow a specifi c sequence.
