What is an example of a lab write up?

A lab write up is a report explaining a scientific experiment and its results. A standard lab write up includes the following sections: I. Introduction/Purpose of the experiment II. Statement of the hypothesis III. Materials used IV. Methods/Procedures V. Observations/Data collected VI. Results/Discussion VII. Conclusion

The following sample lab write up demonstrates how the different sections come together to complete a report.

I. Introduction/Purpose:

This experiment will test the theory that gravity causes objects to fall toward the center of the Earth when they are dropped.

II. Hypothesis:

A soccer ball will fall to the floor when rolled off of a table with a surface 4 feet high,.

III. Materials:

a. Soccer ball

b. Table with a surface height of 4 feet

IV. Methods/Procedure:

The soccer ball was placed on the surface of the table and then pushed so that it rolled off of the table.

V. Observations/Data:

When the soccer ball rolled off the edge of the table, it fell, hit the ground, and bounced three times. It then rolled on the floor until it came to a stop.

VI. Results/Discussion:

Our observations supported the hypothesis that when a soccer ball is rolled off of a table 4 feet high, it will fall to the floor.

VII. Conclusion:

This experiment showed that when a soccer ball was rolled off the surface of a table at 4 feet high it dropped to the ground. This result supports the theory that gravity causes objects to fall toward the center of the Earth when they are dropped.
