Correctly writing lab reports will enhance your scientific communication skills. We will use this Circle Lab to model proper techniques for sharing information by focusing on the Conclusion section of a lab report. Your conclusion will have three parts: a restatement of the purpose (which answers the question, "Why did we do this activity?"), a brief description of the results of the activity and what you learned (do not include the procedures), and possible sources of error (be specific, for example, "human error" is too vague). Remember that the conclusion is a narrative that is written in complete sentences.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
